Use libm_alias_double for some dbl-64 functions. Continuing the move of libm aliases to common macros that can create _FloatN / _FloatNx aliases in future, this patch converts some dbl-64 functions to using libm_alias_double, thereby eliminating the need for some ldbl-opt wrappers. This patch deliberately limits what functions are converted so that it can be verified by comparison of stipped binaries. Specifically, atan and tan are excluded because they first need converting to being weak aliases; fma is omitted as it has additional complications with versions in other directories (removing the ldbl-opt version can e.g. cause the ldbl-128 version to be used instead of dbl-64); and functions that have both dbl-64/wordsize-64 and ldbl-opt versions are excluded because ldbl-opt currently always wraps dbl-64 function versions, so changing those will result in platforms using both ldbl-opt and dbl-64/wordsize-64 (i.e. alpha) starting to use the dbl-64/wordsize-64 versions of those functions (which is good, as an optimization, but still best separated from the present patch to get better validation). Tested for x86_64, and tested with build-many-glibcs.py that installed stripped shared libraries are unchanged by the patch. * sysdeps/ieee754/dbl-64/s_asinh.c: Include <libm-alias-double.h>.

New generic powf without wrapper on aarch64: powf reciprocal-throughput: 4.2x faster powf latency: 2.6x faster old worst-case error: 1.11 ulp new worst-case error: 0.82 ulp aarch64 .text size: -780 bytes aarch64 .rodata size: +144 bytes powf(x,y) is implemented as exp2(y*log2(x)) with the same algorithms that are used in exp2f and log2f, except that the log2f polynomial is larger for extra precision and its output (and exp2f input) may be scaled by a power of 2 (POWF_SCALE) to simplify the argument reduction step of exp2 (possible when efficient round and convert toint operation is available). The special case handling tries to minimize the checks in the hot path. When the input of exp2_inline is checked, int arithmetics is used as that was faster on the tested aarch64 cores. * math/Makefile (type-float-routines): Add e_powf_log2_data. * sysdeps/ieee754/flt-32/e_powf.c: New implementation. * sysdeps/ieee754/flt-32/e_powf_log2_data.c: New file. * sysdeps/ieee754/flt-32/math_config.h (__powf_log2_data): Define.

Simplify C99 isgreater macros Simplify the C99 isgreater macros. Although some support was added in GCC 2.97, not all targets added support until GCC 3.1.

Fix nearbyint arithmetic moved before feholdexcept (bug 22225). In <https://sourceware.org/ml/libc-alpha/2013-05/msg00722.html> I remarked on the possibility of arithmetic in various nearbyint implementations being scheduled before feholdexcept calls, resulting in spurious "inexact" exceptions. I'm now actually observing this occurring in glibc built for ARM with GCC 7 (in fact, both copies of the same addition/subtraction sequence being combined and moved out before the conditionals and feholdexcept/fesetenv pairs), resulting in test failures. This patch makes the nearbyint implementations with this particular feholdexcept / arithmetic / fesetenv pattern consistently use math_opt_barrier on the function argument when first used in arithmetic, and also consistently use math_force_eval before fesetenv (the latter was generally already done, but the dbl-64/wordsize-64 implementation used math_opt_barrier instead, and as math_opt_barrier's intended effect is through its output value being used, such a use that doesn't use the return value is suspect). Tested for x86_64 (--disable-multi-arch so more of these implementations get used), and for ARM in a configuration where I saw the problem scheduling.

Fix make-syscalls.sh VDSO support for GCC 8. sysdeps/unix/make-syscalls.sh has support, used only by x32, for generating IFUNCs for kernel VDSO symbols. This support creates IFUNCs by setting symbol types manually, which is bad for debug info and does not work with current GCC mainline because it results in errors from the checks on types of function aliases. This patch fixes it to use the common __ifunc macro, which uses the ifunc attribute when available and so works with GCC mainline. Note however that the original error resulted from an indirect inclusion of a header declaring __gettimeofday from the generated sources, and using __ifunc now relies on such an indirect inclusion remaining as it means use of __typeof to determine the correct types. If glibc's headers change in such a way as to remove that indirect inclusion, it will become necessary to change the syscalls.list syntax for VDSO syscalls so the name of the header to include can be specified. Tested (compilation only) with build-many-glibcs.py that this fixes the build for x32 with GCC mainline. * sysdeps/unix/make-syscalls.sh: Use __ifunc to define symbols using VDSO.

Fix range check in do_tunable_update_val Current implementation of tunables does not set arena_max and arena_test values. Any value provided by glibc.malloc.arena_max and glibc.malloc.arena_test parameters is ignored. These tunables have minval value set to 1 (see elf/dl-tunables.list file) and undefined maxval value. In that case default value (which is 0. see scripts/gen-tunables.awk) is being used to set maxval. For instance, generated tunable_list[] entry for arena_max is: (gdb) p *cur $1 = {name = 0x7ffff7df6217 "glibc.malloc.arena_max", type = {type_code = TUNABLE_TYPE_SIZE_T, min = 1, max = 0}, val = {numval = 0, strval = 0x0}, initialized = false, security_level = TUNABLE_SECLEVEL_SXID_IGNORE, env_alias = 0x7ffff7df622e "MALLOC_ARENA_MAX"} As a result, any value of glibc.malloc.arena_max is ignored by TUNABLE_SET_VAL_IF_VALID_RANGE macro __type min = (__cur)->type.min; <- initialized to 1 __type max = (__cur)->type.max; <- initialized to 0! if (min == max) <- false { min = __default_min; max = __default_max; } if ((__type) (__val) >= min && (__type) (val) <= max) <- false { (__cur)->val.numval = val; (__cur)->initialized = true; } Assigning correct min/max values at a build time fixes a problem. Plus, a bit of optimization: Setting of default min/max values for the given type at a run time might be eliminated. * elf/dl-tunables.c (do_tunable_update_val): Range checking fix. * scripts/gen-tunables.awk: Set unspecified minval and/or maxval values to correct default value for given type.

Use generic __ifunc for SPARC. glibc fails to build with GCC mainline for SPARC because of the use of manually-created IFUNCs, which fail the tests of compatibility of function alias types. This patch changes sparc-ifunc.h to use the generic __ifunc in defining sparc_libm_ifunc. The generic __ifunc can use the GCC ifunc attribute when available, so ensuring type-correctness as well as better debug info than when setting symbol types in asm statements. Note that for this to fix the build with GCC mainline the GCC patch <https://gcc.gnu.org/ml/gcc-patches/2017-09/msg01779.html>, or building GCC with --enable-gnu-indirect-function, is also needed.

Fix ia64 executable stack default (bug 22156). As per https://gcc.gnu.org/ml/gcc-patches/2017-09/msg01220.html ia64 defaults to non-executable stacks in the Linux kernel (furthermore, the use of function descriptors means that trampolines for nested function pointers never need an executable stack). glibc however defines DEFAULT_STACK_PERMS to include PF_X for that architecture, meaning (a) elf/check-execstack fails and (b) (from code inspection, not tested, but this is why I think this is a user-visible bug) thread stacks are unnecessarily mapped with execute permission. This patch fixes the DEFAULT_STACK_PERMS definition in question. Tested (compilation only) with build-many-glibcs.py for ia64. This fixes the check-execstack failure.

posix: Add compat glob symbol to not follow dangling symbols This patch follows commit 5554304f0 (posix: Allow glob to match dangling symlinks [BZ #866]) by adding a compat symbol that follow previous semantic of not following dangling symlinks and thus avoiding call gl_lstat with GLOB_ALTDIRFUNC. It avoids failure with old binaries that not set the alternate function pointer for lstat (GNUmake for instance). The following scenario, for instance, fails with current GNUmake because glibc will access unitialized memory when calling gl_lstat: $ cat src/t/t.c int main () { return 0; } $ cat Makefile SRC = $(wildcard src/*/t.c) OBJ = $(patsubst src/%.c, obj/%.o, $(SRC)) prog: $(OBJ) $(CC) $(CFLAGS) $(LDFLAGS) $(LIBS) $(OBJ) -o prog obj/%.o: src/%.c $(CC) $(CFLAGS) -c $< -o $@ $ make This works as expected with the patch applied. Since it is for generic ABI, default compat symbols are added with override for Linux due LFS. Now we have two compat symbols for glob on Linux: 1. sysdeps/unix/sysv/linux/oldglob.c which implements glob64 with the old dirent layout. For this implementation I also set it to not follow dangling symlinks (which is the safest path). 2. sysdeps/unix/sysv/linux/glob{64}-lstat-compat.c which implements the compat symbol for dangling symlinks. As for generic glob, the implementation uses XSTAT_IS_XSTAT64 to define whether both __glob_lstat_compat and __glob64_lstat_compat should be different implementations. For archictures that define XSTAT_IS_XSTAT64, __glob_lstat_compat is aliased to __glob64_lstat_compat. 3. sysdeps/unix/sysv/linux/alpha/oldglob.c with a different glob_t layout. As for 1. this patch changes it to not follow dangling symlinks. The patch also bumps _GNU_GLOB_INTERFACE_VERSION to 2 to advertise the new semantic. On GNUmake, for instance, it will force to it use its internal glob implementation instead and avoiding triggering the same failure on builds against newer GLIBCs. Checked on x86_64-linux-gnu and i686-linux-gnu. I also checked with a build against the major ABIs required to check for the abilist.

Optimized generic expf and exp2f with wrappers Based on new expf and exp2f code from https://github.com/ARM-software/optimized-routines/ with wrapper on aarch64: expf reciprocal-throughput: 2.3x faster expf latency: 1.7x faster without wrapper on aarch64: expf reciprocal-throughput: 3.3x faster expf latency: 1.7x faster without wrapper on aarch64: exp2f reciprocal-throughput: 2.8x faster exp2f latency: 1.3x faster libm.so size on aarch64: .text size: -152 bytes .rodata size: -1740 bytes expf/exp2f worst case nearest rounding error: 0.502 ulp worst case non-nearest rounding error: 1 ulp Error checks are inline and errno setting is in separate tail called functions, but the wrappers are kept in this patch to handle the _LIB_VERSION==_SVID_ case. (So e.g. errno is set twice for expf calls and once for __expf_finite calls on targets where the new code is used.) Double precision arithmetics is used which is expected to be faster on most targets (including soft-float) than using single precision and it is easier to get good precision result with it. Const data is kept in a separate translation unit which complicates maintenance a bit, but is expected to give good code for literal loads on most targets and allows sharing data across expf, exp2f and powf. (This data is disabled on i386, m68k and ia64 which have their own expf, exp2f and powf code.) Some details may need target specific tweaks: - best convert and round to int operation in the arg reduction may be different across targets. - code was optimized on fma target, optimal polynomial eval may be different without fma. - gcc does not always generate good code for fp bit representation access via unions or it may be inherently slow on some targets. The libm-test-ulps will need adjustment because.. - The argument reduction ideally uses nearest rounded rint, but that is not efficient on most targets, so the polynomial can get evaluated on a wider interval in non-nearest rounding mode making 1 ulp errors common in that case. - The polynomial is evaluated such that it may have 1 ulp error on negative tiny inputs with upward rounding. * math/Makefile (type-float-routines): Add math_errf and e_exp2f_data. * sysdeps/aarch64/fpu/math_private.h (TOINT_INTRINSICS): Define.

Use libm_alias_float in flt-32. This patch makes flt-32 libm functions use libm_alias_float to define public interfaces (in cases where _Float32 aliases of those interfaces would be appropriate, so not for finitef / isinff / isnanf).

Let fpclassify use the builtin when optimizing for size in C++ mode (bug 22146) When optimization for size is on (-Os), fpclassify does not use the type-generic __builtin_fpclassify builtin, instead it uses __MATH_TG. However, when library support for float128 is available, __MATH_TG uses __builtin_types_compatible_p, which is not available in C++ mode. On the other hand, libstdc++ undefines (in cmath) many macros from math.h, including fpclassify, so that it can provide its own functions. However, during its configure tests, libstdc++ just tests for the availability of the macros (it does not undefine them, nor does it provide its own functions). Finally, when libstdc++ is configured with optimization for size enabled, its configure tests include math.h and get the definition of fpclassify that uses __MATH_TG (and __builtin_types_compatible_p). Since libstdc++ does not undefine the macros during its configure tests, they fail. This patch lets fpclassify use the builtin in C++ mode, even when optimization for size is on. This allows the configure test in libstdc++ to work. Tested for powerpc64le and x86_64. [BZ #22146] math/math.h: Let fpclassify use the builtin in C++ mode, even when optimazing for size.

This accords with the principle that the output of running libc.so.6 is not the place to credit particular contributions (the manual is), and with all other configuration options not mentioned there, it doesn't seem appropriate to focus there on the one question of whether the one remaining piece configured as an add-on was enabled or not.

Remove conditional on LDBL_MANT_DIG from e_lgammal_r.c The IEEE 754 implementation of lgammal in sysdeps/ieee754/ldbl-128/ used to be shared by IBM's implementation in sysdeps/ieee754/ldbl-128ibm/ (by an inclusion of the source file). In order for the algorithm to work for IBM's implementation, a check for LDBL_MANT_DIG was required. Since the source file is no longer shared, the requirement for the check is gone.

ldbl-128ibm: Automatic replacing of _Float128 and L() The ldbl-128ibm implementation of j0l, j1l, lgammal_r, and cbrtl, as well as the tables used by expl were copied from ldbl-128. However, the original files used _Float128 for the type and L() for the literal suffix. This patch uses the following sed command to rewrite _Float128 as long double and L(x) as xL (for e_expl.c, e_j0l.c, e_j1l.c, e_lgammal_r.c, and t_expl.h): sed -i <filename> \ -e "/^#define _Float128 long double/d" \ -e "/^#define L(x) x ## L/d" \ -e "/L(/s/)/L/" \ -e "/L(/s/L(//" \ -e "s/_Float128/long double/g" For sysdeps/ieee754/ldbl-128ibm/s_cbrtl.c, this sed command incorrectly replaces a few occurrences of L(), so the following command is used instead: sed -i sysdeps/ieee754/ldbl-128ibm/s_cbrtl.c \ -e "/^#define _Float128 long double/d" \ -e "/^#define L(x) x ## L/d" \ -e "s/L(0\.3\{40\})/0.3333333333333333333333333333333333333333L/" \ -e "s/L(3\.7568280825958912391243e-1)/3.7568280825958912391243e-1L/" \ -e "/L(/s/)/L/" \ -e "/L(/s/L(//" \ -e "s/_Float128/long double/g" Tested for powerpc64le with patched [1] and unpatched gcc.

ldbl-128ibm: Copy implementations from ldbl-128 instead of including them Some files under sysdeps/ieee754/ldbl-128ibm/ are able to reuse the implementation in sysdeps/ieee754/ldbl-128/ by defining _Float128 to long double. This relied on compiler support for _Float128 being disabled. On powerpc, such support was disabled by default, however, it got enabled by default [1] in GCC 8. This patch copies the implementations from ldbl-128 to ldbl-128ibm. The uses of _Float128 and L() are kept intact in this patch and are replaced with a script in a subsequent patch.

powerpc: Add redirection for finitef128, isinf128, and isnanf128 On powerpc64le, compiler support for float128 is not enabled by default on gcc. To enable it, the flag -mfloat128 must be passed as a command line option to the compiler. This means that only the few files that actively have -mfloat128 passed as an argument get compiler support for float128, whereas all other files don't. When -mfloat128 becomes enabled by default on powerpc [1], all the files that do not currently have compiler support for float128 enabled during their compilation, will start to have it. This will lead to build errors in s_finite.c, s_isinf.c, and s_isnan.c. The errors are due to the unintended macro expansion of __finitef128 to __redirect_finitef128 in math/bits/mathcalls-helper-functions.h. In that header, __MATHDECL_1 takes '__finite' and 'f128' as arguments and concatenates them. However, since '__finite' has been redefined in s_finite.c, the function declaration becomes __redirect_finitef128: extern int __redirect___finitef128 (_Float128 __value) __attribute__ ((__nothrow__ )) __attribute__ ((__const__)); This declaration itself is OK. The problem arises when include/math.h creates the hidden prototype ('hidden_proto (__finitef128)'), which expands to: extern __typeof (__finitef128) __finitef128 __attribute__ ((visibility ("hidden"))); Since __finitef128 is not declared, __typeof fails. This effect was already true for the 'float' and 'long double' versions and is now true for float128. Likewise for isinsff128 and isnanf128. This patch defines __finitef128 as __redirect___finitef128 in sysdeps/powerpc/powerpc64/fpu/multiarch/s_finite.c, similarly to what's done for the float and long double versions of these functions, to get rid of the build error. Likewise for isinff128 and isnanf128.

Fix BZ# 22180. POSIX requires that dlclose() and exit() be thread safe, therefore you can have one thread in the middle of dlclose() and another thread executing exit() without causing any undefined behaviour on the part of the implementation. The existing implementation had a flaw that exit() exit handler processing did not consider a concurrent dlclose() and would not mark already run exit handlers using the ef_free flavour. The consequence of this is that a concurrent exit() with dlclose() will run all the exit handlers that dlclose() had not yet run, but then will block on the loader lock. The concurrent dlclose() will continue to run all the exit handlers again (twice) in violation of the Itanium C++ ABI requirements for __cxa_atexit(). This commit fixes this by having exit() mark all handlers with ef_free to ensure that concurrent dlclose() won't re-run registered exit handlers that have already run.

Remove non-add-on Banner files. Various subdirectories of glibc include Banner files to put some text in the output of executing libc.so.6, under "Available extensions". Some of those subdirectories (e.g. crypt) may originally have been add-ons (and so optional, so a particular glibc build might or might not have included them), but except for libidn they aren't now (or if only included in some builds, in the case of soft-fp, the inclusion depends on the architecture for which glibc is configured rather than having any glibc configuration for which it's an optional feature), and it doesn't seem useful for the libc.so.6 output to call out a few features like that.

Use libm_alias_ldouble in math/. This patch converts libm function implementations in math/ from using weak_alias to using libm_alias_ldouble to define public function names, in cases where it would be appropriate to define _Float128 / _Float64x aliases for those functions as well (in cases where either or both of those types exist and have the same ABI as long double). This eliminates many ldbl-opt wrappers round these function implementations. Tested for x86_64, and with build-many-glibcs.py. All installed stripped shared libraries are unchanged except for libm.so on powerpc64le. As noted for a previous patch, powerpc64le's use of ldbl-opt means various long double functions get defined using long_double_symbol which gives them an explicit symbol version in the object files, and this patch results in some such functions using weak_alias instead (because powerpc64le never had a previous version of these functions for long double = double); both produce a valid libm.so with the same public symbols at the same versions, but macros expanding to call weak_alias is cleaner in this case. * math/s_fmal.c: Include <libm-alias-ldouble.h>.

Fix powerpc64le problem from last ldbl-opt patch. This patch fixes a problem on powerpc64le that I missed in initial testing of my last patch to ldbl-opt. In the specific case of powerpc64le, the weak aliases for exp10l and remainderl do not get defined in the generic wrappers because of how those wrappers undefine and redefine weak_alias. This patch restores those aliases in the ldbl-opt code. Tested (compilation only) for powerpc64le with build-many-glibcs.py. * sysdeps/ieee754/ldbl-opt/w_exp10l_compat.c [LIBM_SVID_COMPAT && !LONG_DOUBLE_COMPAT (libm, GLIBC_2_1)] (weak_alias): Undefine and redefine.

Use libm_alias_ldouble in math/. This patch converts libm function implementations in math/ from using weak_alias to using libm_alias_ldouble to define public function names, in cases where it would be appropriate to define _Float128 / _Float64x aliases for those functions as well (in cases where either or both of those types exist and have the same ABI as long double). This eliminates many ldbl-opt wrappers round these function implementations. Tested for x86_64, and with build-many-glibcs.py. All installed stripped shared libraries are unchanged except for libm.so on powerpc64le. As noted for a previous patch, powerpc64le's use of ldbl-opt means various long double functions get defined using long_double_symbol which gives them an explicit symbol version in the object files, and this patch results in some such functions using weak_alias instead (because powerpc64le never had a previous version of these functions for long double = double); both produce a valid libm.so with the same public symbols at the same versions, but macros expanding to call weak_alias is cleaner in this case. * math/s_fmal.c: Include <libm-alias-ldouble.h>.

AArch64: use movz/movk instead of literal pools in start.S eXecute-Only Memory (XOM) is a protection mechanism against some ROP attacks. XOM sets the code as executable and unreadable, so the access to any data, like literal pools, in the code section causes the fault with XOM. The compiler can disable literal pools for C source files, but not for assembly files, so I use movz/movk instead of literal pools in start.S for XOM. I add MOVL macro with movz/movk instructions like movl pseudo-instruction in armasm, and use the macro instead of literal pools. * sysdeps/aarch64/start.S: Use MOVL instead of literal pools. * sysdeps/aarch64/sysdep.h (MOVL): Add MOVL macro.

Remove ENOSYS math/ function stubs. The math/ directory has various stub implementations of functions (generally long double functions, plus sqrtf128) that set errno to ENOSYS and print a message. These are a relic of when the long double libm implementation in glibc was originally incomplete. They are only present for a limited set of libm functions, not all those that would need implementing for any hypothetical new long double format, and only for long double (plus sqrtf128), not for other floating-point types. I removed the corresponding ENOSYS tests in the testsuite in <https://sourceware.org/ml/libc-alpha/2013-05/msg00599.html>. I think these stubs are an inherently different case from stubs for functionality needing OS-specific implementations, since floating-point formats are generally standardized between modern processors (a new long double format does not seem likely - I'd expect new ports all to have long double = binary128 or long double = binary64 - though _Float16 functions *f16 are entirely possible in future) and libm functions are generally only expected to fail for domain / range / pole errors, not for other unknown system-specific conditions the way the functions needing OS-specific implementations may fail. This patch removes these stub implementations. The effect (which, as noted above, was actually mostly already the case, given the incompleteness of the set of stubs, and was certainly the case if you wanted your libm port to *work* rather than just build) is that any new long double format needs to provide a full set of functions for the build to succeed; any port using ldbl-128 needs to provide sqrtl (possibly using the soft-fp version from another port); any port using ldbl-96 needs to provide all those functions that all of x86_64/i386/ia64/m68k provide rather than getting from the ldbl-96 directory; any port with _Float128 as a type with a distinct format needs to provide sqrtf128. Tested for x86_64.

Use libm_alias_double in math/. This patch converts libm function implementations in math/ from using weak_alias to using libm_alias_double to define public function names, in cases where it would be appropriate to define _Float64 / _Float32x aliases for those functions as well. This eliminates many NO_LONG_DOUBLE conditionals and ldbl-opt wrappers round these function implementations. Tested for x86_64. Also tested with build-many-glibcs.py. Binary differences seen are that the different order in which remainder and drem symbols get defined as a result of this patch (the same source file defines the same aliases, but in a different order of definition) changes the order of symbols in the final libm.so when long double = double, and for ldbl-opt configurations, the compat symbols for Bessel functions were previously defined by e.g. "compat_symbol (libm, j0, j0l, GLIBC_2_0)", which declares j0l as a compat symbol based on j0 and so makes j0l weak because j0 is weak, and are now defined (indirectly via the relevant macros) based on e.g. __j0, so are no longer weak because __j0 isn't weak. * math/s_fma.c: Include <libm-alias-double.h>.

Remove ENOSYS math/ function stubs. The math/ directory has various stub implementations of functions (generally long double functions, plus sqrtf128) that set errno to ENOSYS and print a message. These are a relic of when the long double libm implementation in glibc was originally incomplete. They are only present for a limited set of libm functions, not all those that would need implementing for any hypothetical new long double format, and only for long double (plus sqrtf128), not for other floating-point types. I removed the corresponding ENOSYS tests in the testsuite in <https://sourceware.org/ml/libc-alpha/2013-05/msg00599.html>. I think these stubs are an inherently different case from stubs for functionality needing OS-specific implementations, since floating-point formats are generally standardized between modern processors (a new long double format does not seem likely - I'd expect new ports all to have long double = binary128 or long double = binary64 - though _Float16 functions *f16 are entirely possible in future) and libm functions are generally only expected to fail for domain / range / pole errors, not for other unknown system-specific conditions the way the functions needing OS-specific implementations may fail. This patch removes these stub implementations. The effect (which, as noted above, was actually mostly already the case, given the incompleteness of the set of stubs, and was certainly the case if you wanted your libm port to *work* rather than just build) is that any new long double format needs to provide a full set of functions for the build to succeed; any port using ldbl-128 needs to provide sqrtl (possibly using the soft-fp version from another port); any port using ldbl-96 needs to provide all those functions that all of x86_64/i386/ia64/m68k provide rather than getting from the ldbl-96 directory; any port with _Float128 as a type with a distinct format needs to provide sqrtf128. Tested for x86_64.

[BZ #21745] powerpc: build some IFUNC math functions for libc and libm Some math functions have to be distributed in libc because they're required by printf. libc and libm require their own builds of these functions, e.g. libc functions have to call __stack_chk_fail_local in order to bypass the PLT, while libm functions have to call __stack_chk_fail. While math/Makefile treat the generic cases, i.e. s_isinff, the multiarch Makefile has to treat its own files, i.e. s_isinff-ppc64. [BZ #21745] * sysdeps/powerpc/powerpc64/fpu/multiarch/Makefile: [$(subdir) = math] (sysdep_calls): New variable. Has the previous contents of sysdep_routines, but re-sorted.. [$(subdir) = math] (sysdep_routines): Re-use the contents from sysdep_calls. [$(subdir) = math] (libm-sysdep_routines): Remove the functions defined in sysdep_calls and replace by the respective m_* names. * sysdeps/powerpc/powerpc64/fpu/multiarch/s_isnan-ppc64.S: (compat_symbol): Undefine to avoid duplicated compat symbols in libc.

Use libm_alias_float in math/. This patch converts libm function implementations in math/ from using weak_alias to using libm_alias_float to define public function names, in cases where it would be appropriate to define _Float32 aliases for those functions as well. expf and exp2f are omitted from this patch, given the in-progress patches that would change their symbol versioning arrangements (at a later stage it will be necessary to add macros that can be used for functions with such symbol versioning arrangements - which will apply to lgammaf as well - but for the initial patches in this area I'm just dealing with easy cases, and any symbol versioning changes to these functions while the work is in progress can effectively just undo the libm_alias_* changes as regards those functions).

Make more libm functions into weak aliases. Many libm functions define the function as __<func> and then define <func> as a weak alias. This is not at all limited to cases where there is an internal call that has namespace reasons to need to call __<func> instead of <func>. The common macros for creating libm function aliases work on the basis of public function names all being aliases; that is, they define aliases for functions using the above pattern. Thus, where a function just defines the public name <func> directly, changing that to be a weak alias enables a subsequent conversion to the common macros to retain the exact existing symbols (and so be testable by comparison of stripped binaries). This patch converts many existing functions to use the weak alias pattern, as preparation for subsequent conversions to common macros. I do expect that _FloatN/_FloatNx function aliases will end up needing new variants of the common macros that do *not* create the original float / double / long double name of a function - for cases where that name is created specially to give it a particular symbol version, for example - but for functions that can use the most common macros to create all the public names as aliases, it makes sense for them to do so. Regarding the Bessel function wrappers in this patch: only float and double wrappers are changed because the long double wrappers already used the weak alias pattern.

Add new codepage charmaps/IBM858 [BZ #21084] This code page is identical to code page 850 except that X'D5' has been changed from LI61 (dotless i) to SC20 (euro symbol). The code points from /x01 to /x1f in the /localedata/charmaps/IBM858 file have the same mapping as those in localedata/charmaps/ANSI_X3.4-1968. That means they disagree with with ftp://ftp.software.ibm.com/software/globalization/gcoc/attachments/CP00858.txt in that range. For example, localedata/charmaps/IBM858 and localedata/charmaps/ANSI_X3.4-1968 have: “<U0001> /x01 START OF HEADING (SOH)” whereas CP00858.txt has: “01 SS000000 Smiling Face” That means that CP00858.txt is not really ASCII-compatible and to make it ASCII-compatible we deviate fro CP00858.txt in the code points from /x01 to /x1f.

Define and use libm_alias_float128. Continuing the process of setting up common macros for libm function aliases, with a view to using them to define _FloatN / _FloatNx aliases in future, this patch adds a libm_alias_float128 macro and uses it in the type-generic templates. (_Float128 functions will end up with _Float64x aliases on powerpc64le, but not on x86_64/x86/ia64 because _Float64x has long double format there, and the macro will provide a single place for the conditionals for that choice, as well as for once ldbl-128 functions always build *f128 and need conditionals for whether to have *l aliases.) Tested for x86_64. Also tested with build-many-glibcs.py that installed stripped shared libraries are unchanged by the patch. * sysdeps/generic/libm-alias-float128.h: New file. * sysdeps/generic/math-type-macros-float128.h: Include <libm-alias-float128.h>.

Continuing the process of setting up common macros for libm function aliases, with a view to using them to define _FloatN / _FloatNx aliases in future, this patch adds a libm_alias_ldouble macro and uses it in the type-generic templates. Since math-type-macros-ldouble.h already did the appropriate thing for each symbol (weak_alias or long_double_symbol), this is just a straightforward rearrangement of code, to make the required logic available in a place that can also be used outside of the type-generic templates in future (in particular, to eliminate various wrappers for functions in ldbl-opt and ldbl-64-128). Tested for x86_64. Also tested with build-many-glibcs.py that installed stripped shared libraries are unchanged by the patch. * sysdeps/generic/libm-alias-ldouble.h: New file. * sysdeps/ieee754/ldbl-opt/libm-alias-ldouble.h: Likewise. * sysdeps/ieee754/ldbl-opt/math-type-macros-ldouble.h: Remove. * sysdeps/generic/math-type-macros-ldouble.h: Include <libm-alias-ldouble.h>.

Clear up log1p, ldexp, scalbn, scalbln compat handling. This patch cleans up how compat symbols / long double versioning are handled for log1p, ldexp, scalbn and scalbln functions. The general principle is to do as much as possible through the type-generic templates. Previously, when errno-setting wrappers were added the compat long double symbols were left pointing directly to the underlying implementations; they are moved to point to the errno-setting wrappers. For the functions also present in libc, compat symbol handling for the libc copies needs to go in ldbl-opt wrappers, but the type-generic templates can handle it for the libm copies. There is no need for w_scalbln_template.c to disable the creation of an unused internal alias (such code made sense in the context of patches trying to avoid any changes to generated code for ease of comparison, but can be removed in a change that specifically does intend to change details of where symbols point).

Define and use libm_alias_double. Continuing the process of setting up common macros for libm function aliases, with a view to using them to define _FloatN / _FloatNx aliases in future, this patch adds a libm_alias_double macro and uses it in the type-generic templates. This macro handles defining aliases for double, and for long double in the NO_LONG_DOUBLE case. It also handles defining compat symbols for long double = double for architectures that changed their long double format. By so doing, it eliminates the need for the M_LIBM_NEED_COMPAT and declare_mgen_libm_compat macros; the single declare_mgen_alias call in each template now suffices to define all required compat symbols. When used for more double functions (not based on type-generic templates), I expect it will eliminate the need for most ldbl-opt wrappers for such functions. A few special cases are needed. __clog10l is a public symbol (for historical reasons) so needs to be given appropriate compat versions for architectures that changed their long double format, but is not defined as an alias using the normal macros since __clog10* are *not* public symbols for _FloatN / _FloatNx types. For scalbn, scalbln and log1p, the changes adding errno setting support for those functions left compat symbols pointing directly to the non-errno-setting implementations. There is no requirement for the compat symbols not to set errno; that just made for the simplest patches at that time. Now, with these common macros, it's natural to redirect the compat symbols to the errno-setting wrappers, which I intend to do in a separate patch. Tested for x86_64, and with build-many-glibcs.py. For ldbl-opt platforms the stripped libm.so binaries are changed (disassembly unchanged) because the details of how the clog10l compat symbol is created mean it ceases to be weak as it was before; for other platforms, stripped libm.so binaries are unchanged. 2017-09-13 Joseph Myers <joseph@codesourcery.com> * sysdeps/generic/libm-alias-double.h: New file. * sysdeps/ieee754/ldbl-opt/libm-alias-double.h: Likewise. * sysdeps/generic/math-type-macros-double.h: Include <libm-alias-double.h>.

Remove declare_mgen_alias_2. The libm template machinery includes a macro declare_mgen_alias_2, to define two function aliases rather than one. This macro is only used in one place, to define ldexp and scalbn, and only has one nondefault definition, for double in the case where long double has the same format. That definition is because declare_mgen_alias for double, in that case, defines <internal-func>l as an alias of <internal-func>, so cannot be called twice for aliases of the same function. Now, I suspect the <internal-func>l aliases are generally not needed (with maybe a few exceptions such as __clog10l, which is an exported function). But even in the presence of them, there is no need for a special declare_mgen_alias_2 macro for this case. This patch eliminates the need for such a macro by defining __wrap_scalbn<suffix> as an alias of __ldexp<suffix>, and then using that when defining the scalbn public aliases. This is similar to how such internal aliases are created for functions with multiple symbol versions, for example. Tested for x86_64, and with build-many-glibcs.py. (There *are* some cases where installed stripped shared libraries change - not in the generated code but because such changes to static symbols on input to ld, even nonexported symbols that don't affect the code or dynamic symbols, can affect the particular representation in the output of string tables, hash tables etc.) * sysdeps/generic/math-type-macros.h [!declare_mgen_alias_2] (declare_mgen_alias_2): Remove. * sysdeps/generic/math-type-macros-double.h [NO_LONG_DOUBLE && !declare_mgen_alias_2] (declare_mgen_alias_2): Likewise. * math/s_ldexp_template.c (M_SUF (__wrap_scalbn)): Define strong alias.

Add aliases.
Define and use a libm_alias_float macro. Fully supporting TS 18661-3 _FloatN / _FloatNx types in the cases where they have the same format as other supported types (in line with the principles described at <https://sourceware.org/ml/libc-alpha/2017-01/msg00333.html>) means adding a lot of function aliases to libm (and a few to libc). float functions will have *f32 aliases, double functions will have *f32x and *f64 aliases, long double functions may have *f64x, *f128 or both aliases depending on the configuration, float128 functions have have *f64x aliases depending on the configuration. At present, most individual libm functions have their own weak_alias calls to define the public names for those functions. For TS 18661-3 support, it is desirable that functions not all need to duplicate the logic for which alias names to define. Thus, common macros for defining the public aliases to a libm function make sense. In the double and long double cases, such macros will also help simplify existing code (with LONG_DOUBLE_COMPAT etc. conditionals), by eliminating existing conditionals and ldbl-opt / ldbl-64-128 wrappers (using the generated ldbl-compat-choose.h to allow a single macro definition to expand appropriately for each symbol depending on LONG_DOUBLE_COMPAT for that symbol). This patch starts the process of adding such macros with a straightforward case: a libm_alias_float macro, initially only used in the case of type-generic templates, to define aliases for float functions (currently just the *f public names, in future also *f32). Future patches are intended to add such macros for other types and to extend the cases in which they are used, with a view to as many places as possible using them before support for _FloatN / _FloatNx aliases is enabled. (I think it's inevitable that some places doing architecture-specific things with aliases and symbol versioning may end up needing to replicate logic for the new aliases, but hopefully the number of such places can be kept to a minimum.) The libm_alias_float macro takes unsuffixed names for both the internal and public function names. The need for unsuffixed public names is obvious, since such macros will end up defining multiple public names with different suffixes. Unsuffixed internal names are because I expect the ldbl-128 functions to end up in a form that always defines *f128 names and sometimes also defines *l names - with the main internal names being e.g. __ieee754_<func>f128 (so many macros in float128_private.h can go away). But __ieee754_<func>l aliases will still be needed for e.g. use from math/ complex functions, meaning the alias macro needs to see just __ieee754_<func> as internal name so it can create an alias based on that name. Since libm_alias_float128 will thus need the unsuffixed internal name, it seems to make sense for all such macros to receive the unsuffixed name. Tested for x86_64. Also tested with build-many-glibcs.py that installed stripped shared libraries are unchanged by the patch. * sysdeps/generic/libm-alias-float.h: New file. * sysdeps/generic/math-type-macros-float.h: Include <libm-alias-float.h>.

x86: Add x86_64 to x86-64 HWCAP [BZ #22093] Before glibc 2.26, ld.so set dl_platform to "x86_64" and searched the "x86_64" subdirectory when loading a shared library. ld.so in glibc 2.26 was changed to set dl_platform to "haswell" or "xeon_phi", based on supported ISAs. This led to shared library loading failure for shared libraries placed under the "x86_64" subdirectory. This patch adds "x86_64" to x86-64 dl_hwcap so that ld.so will always search the "x86_64" subdirectory when loading a shared library. NB: We can't set x86-64 dl_platform to "x86-64" since ld.so will skip the "haswell" and "xeon_phi" subdirectories on "haswell" and "xeon_phi" machines. Tested on i686 and x86-64.

Add fcntl sealing interfaces from Linux 3.17 to bits/fcntl-linux.h. While reviewing Linux 4.13 for glibc header changes needed, I noticed that bits/fcntl-linux.h was missing F_ADD_SEALS etc. from Linux 3.17. I didn't find any discussion indicating this omission is deliberate. Now, these interfaces can only be used with file descriptors created with memfd_create, and we don't have a memfd_create wrapper in glibc (a patch was submitted in October 2014, albeit without documentation / tests, and discussions continued over the next few months, but without consensus on whether to add the interface - and we still lack any general consensus on syscall wrappers), but I don't think that's a reason to exclude the constants from bits/fcntl-linux.h (especially as the header does not look compatible with simultaneously including linux/fcntl.h). (Some of those 2014/2015 discussions raised concerns about difficulty using the memfd_create / sealing interface, but those seem to me more like a question of whether it should be part of the OS-independent GNU API - in my view, even fairly specialized syscalls ought to have wrappers added to glibc if not obsolescent, but there may be cases where we only want to include them in the Linux-specific API and anything in the OS-independent GNU API should be different - rather than being relevant to whether constants for use with fcntl should appear in headers.) * sysdeps/unix/sysv/linux/bits/fcntl-linux.h [__USE_GNU] (F_ADD_SEALS): New macro.

posix: Sync glob with gnulib [BZ #1062] This patch syncs posix/glob.c implementation with gnulib version b5ec983 (glob: simplify symlink detection). The only difference to gnulib code is * DT_UNKNOWN, DT_DIR, and DT_LNK definition in the case there were not already defined. Gnulib code which uses HAVE_STRUCT_DIRENT_D_TYPE will redefine them wrongly because GLIBC does not define HAVE_STRUCT_DIRENT_D_TYPE. Instead the patch check for each definition instead. Also, the patch requires additional globfree and globfree64 files for compatibility version on some architectures. Also the code simplification leads to not macro simplification (not need for NO_GLOB_PATTERN_P anymore). Checked on x86_64-linux-gnu and on a build using build-many-glibcs.py for all major architectures.

For archictures that define XSTAT_IS_XSTAT64, glob{free} is an alias to glob{free}64. * Move i386 olddirent.h header to Linux default directory, since it is the only header with this name and it is shared among different architectures (and used on compat glob symbol as well).

posix: fix glob bugs with long login names Current glob implementation allows unlimited user name for home directory construction on GLOB_TILDE case. To accomplish it glob either construct a name on stack if size are small enough (based on current alloca_used) or in heap otherwise.

posix: Allow glob to match dangling symlinks [BZ #866] This patch makes glob match dangling symlinks. Compared to other glob implementation (*BSD, bash, musl, and other shells as well), GLIBC seems the be the only one that does not match dangling symlinks. As for comment #5 in BZ #866, POSIX does not have any strict specification for dangling symlinks match and it is reasonable that trying to glob everything in a path should return all types of files (such as for a 'rm *'). Also, comment #7 shows even more example where GLIBC current behavior is unexepected. I avoided adding another GNU specific flag to set this behavior and instead make it the default. Although this change the semanthic from previous implementation, I think adding another compat symbol to be really unecessary as from aforementioned reasons (current behavior not defined in any standard, general idea of different implementation is to list dangling symbols). This also sync glob with gnulib commit fd1daf4 (glob: match dangling symlinks). Checked on x86_64-linux-gnu and on a build using build-many-glibcs.py for all major architectures.

posix: accept inode 0 is a valid inode number (BZ #19971) According to this kernel commit 2adc376c55194, d_ino 0 is a regular inode number on Linux (which also matches POSIX, as it does not treat the value as special).

posix: Sync glob with gnulib [BZ #1062] This patch syncs posix/glob.c implementation with gnulib version b5ec983 (glob: simplify symlink detection). The only difference to gnulib code is * DT_UNKNOWN, DT_DIR, and DT_LNK definition in the case there were not already defined. Gnulib code which uses HAVE_STRUCT_DIRENT_D_TYPE will redefine them wrongly because GLIBC does not define HAVE_STRUCT_DIRENT_D_TYPE. Instead the patch check for each definition instead. Also, the patch requires additional globfree and globfree64 files for compatibility version on some architectures.

Prefer new libm function wrappers for !LIBM_SVID_COMPAT. The initial obsoletion of SVID libm error handling left the old wrappers and __kernel_standard still being used for new ports and static linking, just with macro definitions of _LIB_VERSION and matherr that meant symbols with those names were never actually used and the code for different error handling variants could be optimized out. This patch cleans things up further by eliminating the __kernel_standard use for new ports and static linking. Now, the old wrappers no longer generate any code in the !LIBM_SVID_COMPAT case, while the new errno-only wrappers that were added for float128 support are now also used for float, double and long double in that case. The changes are generally straightforward. The w_scalb*_compat wrappers continue to be used (scalb is obsolescent in the sense of not being supported for float128, but is present in supported standards - the 2001 edition of POSIX and earlier XSI versions - so remains supported for static linking and new ports, as do the float and long double variants that are existing GNU extensions). Those wrappers would only call __kernel_standard in the _LIB_VERSION == _SVID_ case. Since we would like to be able to compile most of glibc without optimization, relying on a static function whose only use is under an if (0) condition being optimized away to avoid an undefined __kernel_standard reference may not be a good idea. Thus, the relevant code in the scalb wrappers has LIBM_SVID_COMPAT conditionals added to guarantee it's not built at all in the case where __kernel_standard does not exist. Just as i386 has its own w_sqrt_compat.c, so w_sqrt.c is also added. ia64 gets dummy w_*.c to prevent those files being built where they would conflict with the ia64 libm, as with its existing w_*_compat.c. Conditions disabling code for !LIBM_SVID_COMPAT are needed in both the math/ wrappers and in the long double wrappers in ldbl-opt (to avoid them setting up aliases and symbol versions for undefined symbols). I hope that future cleanups to how libm function aliases and symbol versioning are done will eliminate the need for most of the ldbl-opt wrappers.

Fix pcprofiledump cross-endian condition (bug 22086). debug/pcprofiledump.c contains code that tries to handle other-endian data. This uses a condition "(word & 0xfffffff0) == bswap_32 (0xdeb00000)". This condition is always false (the LHS always has the low four bits zero, the RHS doesn't); a correct comparison would use 0x0fffffff. This results in -Werror=tautological-compare build failures with the tile version of bits/byteswap.h and mainline GCC. https://sourceware.org/ml/libc-testresults/2017-q3/msg00400.html pcprofiledump.c: In function 'main': pcprofiledump.c:118:39: error: bitwise comparison always evaluates to false [-Werror=tautological-compare] int must_swap = (word & 0xfffffff0) == bswap_32 (0xdeb00000); ^~ This patch fixes the condition. Tested for x86_64, and with build-many-glibcs.py that it fixes the build for tilegx-linux-gnu. (Note that I have not tested the actual pcprofiledump functionality, native or cross endian, which lacks any testsuite coverage.)

Obsolete pow10 functions. This patch obsoletes the pow10, pow10f and pow10l functions (makes them into compat symbols, not available for new ports or static linking). The exp10 names for these functions are standardized (in TS 18661-4) and were added in the same glibc version (2.1) as pow10 so source code can change to use them without any loss of portability. Since pow10 is deliberately not provided for _Float128, only exp10, this slightly simplifies moving to the new wrapper templates in the !LIBM_SVID_COMPAT case, by avoiding needing to arrange for pow10, pow10f and pow10l to be defined by those templates.

Remove NO_CANCELLATION macro The NO_CANCELLATION macro is used currently on generic headers to define non cancellable syscalls and on Linux fcntl to implement the non cancellable variation. Former should be single-handled by not-cancel.h header and former could be simplified build both cancellable and non cancellable for default objects and alias the non-cancellable to default one for rtld ones (since Linux already support cancellation as default). This patch thus removes the NO_CANCELLATION macro and its usage. The generic non cancellable fcntl is route to internal fcntl. Checked on x86_64-linux-gnu and i686-linux-gnu.

Simplify HUGE_VAL definitions. There are various bits/huge_val*.h headers to define HUGE_VAL and related macros. All of them use __builtin_huge_val etc. for GCC 3.3 and later. Then there are various fallbacks, such as using a large hex float constant for GCC 2.96 and later, or using unions (with or without compound literals) to construct the bytes of an infinity, with this last being the reason for having architecture-specific files. Supporting TS 18661-3 _FloatN / _FloatNx types that have the same format as other supported types will mean adding more such macros; needing to add more headers for them doesn't seem very desirable. The fallbacks based on bytes of the representation of an infinity do not meet the standard requirements for a constant expression. At least one of them is also wrong: sysdeps/sh/bits/huge_val.h is producing a mixed-endian representation which does not match what GCC does. This patch eliminates all those headers, defining the macros directly in math.h. For GCC 3.3 and later, the built-in functions are used as now. For other compilers, a large constant 1e10000 (with appropriate suffix) is used. This is like the fallback for GCC 2.96 and later, but without using hex floats (which have no apparent advantage here). It is unambiguously valid standard C for all floating-point formats with infinities, which covers all formats supported by glibc or likely to be supported by glibc in future (C90 DR#025 said that if a floating-point format represents infinities, all real values lie within the range of representable values, so the constraints for constant expressions are not violated), but may generate compiler warnings and wouldn't handle the TS 18661-1 FENV_ROUND pragma correctly. If someone is actually using a compiler with glibc that does not claim to be GCC 3.3 or later, but which has a better way to define the HUGE_VAL macros, we can always add compiler conditionals in with alternative definitions. I intend to make similar changes for INF and NAN. The SNAN macros already just use __builtin_nans etc. with no fallback for compilers not claiming to be GCC 3.3 or later.

Simplify NAN definitions. Similar to my patches for HUGE_VAL and INFINITY. this patch eliminates the bits/nan.h headers. __builtin_nanf ("") is used to define NAN for GCC 3.3 and later; the fallback is (0.0f / 0.0f), which is a constant expression for a quiet NaN of type float, but raises a spurious "invalid" exception outside static initializers, which seems the best that can be done purely in standard C.

Fix mcontext_t sigcontext namespace (bug 21457). This patch completes the ucontext.h namespace fixes by fixing issues related to the use of struct sigcontext as mcontext_t, and inclusion of <bits/sigcontext.h> even when struct sigcontext is not so used. Inclusion of <bits/sigcontext.h> by <sys/ucontext.h> is removed; the way to get the sigcontext structure is by including <signal.h> (in a context where __USE_MISC is defined); the sysdeps/generic version of sys/ucontext.h keeps the inclusion by necessity, with a comment about how this is not namespace-clean, but the only configuration that used it, MicroBlaze, gets its own version of the header in this patch. Where mcontext_t was typedefed to struct sigcontext, the contents of struct sigcontext are inserted (with appropriate namespace handling to prefix fields with __ when __USE_MISC is not defined); review should check that this has been done correctly in each case, whether the definition of struct sigcontext comes from glibc headers or from the Linux kernel. This changes C++ name mangling on affected architectures (which do not include x86_64/x86). Tested for x86_64, and with build-many-glibcs.py. 2017-08-14 Joseph Myers <joseph@codesourcery.com> [BZ #21457] * sysdeps/arm/sys/ucontext.h: Do not include <bits/sigcontext.h>. * sysdeps/generic/sys/ucontext.h: Add comment about use of struct sigcontext and namespace requirements. * sysdeps/i386/sys/ucontext.h: Do not include <bits/sigcontext.h>. * sysdeps/m68k/sys/ucontext.h: Likewise. * sysdeps/mips/sys/ucontext.h: Likewise.

Fix m68k bits/math-inline.h macro namespace (bug 22035). As shown by build bot failures <https://sourceware.org/ml/libc-testresults/2017-q3/msg00349.html> the m68k bits/mathinline.h is not namespace-clean: it fails to compile if the user has defined macros f or l before it is included, because of expansions of those arguments to __inline_functions. This patch changes the __inline_functions definitions to take not the suffix but a macro that concatenates it with the function name, to avoid the spurious macro expansions. Tested for m68k with build-many-glibcs.py.

MIPS/o32: Fix internal_syscall5/6/7 Fix a commit cc25c8b4c119 ("New pthread rwlock that is more scalable.") regression and prevent uncontrolled stack space usage from happening when a 5-, 6- or 7-argument syscall wrapper is placed in a loop. The cause of the problem is the use of `alloca' in regular MIPS/Linux wrappers to force the use of the frame pointer register in any function using one or more of these wrappers. Using the frame pointer register is required so as not to break frame unwinding as the the stack pointer is lowered within the inline asm used by these wrappers to make room for the stack arguments, which 5-, 6- and 7-argument syscalls use with the o32 ABI. The regular MIPS/Linux wrappers are macros however, expanded inline, and stack allocations made with `alloca' are not discarded until the return of the function they are made in. Consequently if called in a loop, then virtual memory is wasted, and if the loop goes through enough iterations, then ultimately available memory can get exhausted causing the program to crash. Address the issue by replacing the inline code with standalone assembly functions, which rely on the compiler arranging syscall arguments according to the o32 function calling convention, which MIPS/Linux syscalls also use, except for the syscall number passed and the error flag returned. This way there is no need to fiddle with the stack pointer anymore and all that has to be handled in the new standalone functions is the special handling of the syscall number and the error flag. Redirect 5-, 6- or 7-argument MIPS16/Linux syscall wrappers to these new functions as well, so as to avoid an unnecessary double call the existing wrappers would cause with the new arrangement.

The current bits/math-finite.h approach to defining functions for different types, involving math.h defining _MSUF_ and _MSUFTO_ for the function suffixes involved, is not namespace-clean if one of those suffixes (f, l, f128) is defined as a macro by the user before math.h is included; too many levels of macro expansion occur. Instead, those suffixes should appear directly in the expansion of the macro using ## so they don't get expanded even if defined as macros by the user (that is, math.h should be defining __REDIRFROM_X and __REDIRTO_X directly to use those suffixes rather than suffixes being passed as an argument by macro callers). This patch makes that change. Tested for x86_64. [BZ #22028] * math/math.h [__FINITE_MATH_ONLY__ && __FINITE_MATH_ONLY__ > 0] (_MSUF_): Remove macro.

Provide a C++ version of iszero that does not use __MATH_TG (bug 21930) When signaling nans are enabled (with -fsignaling-nans), the C++ version of iszero uses the fpclassify macro, which is defined with __MATH_TG. However, when support for float128 is available, __MATH_TG uses the builtin __builtin_types_compatible_p, which is only available in C mode. This patch refactors the C++ version of iszero so that it uses function overloading to select between the floating-point types, instead of relying on fpclassify and __MATH_TG.

Simplify math-svid-compat code. Now there are no more assembly wrappers using _LIB_VERSION or __kernel_standard, the math-svid-compat code can be slighly simplified. math-svid-compat.h no longer needs __ASSEMBLER__ conditionals, and the _LIB_VERSION variable no longer needs to be built for static libm, since all references are now in C code that includes math-svid-compat.h and so gets the macro definition of _LIB_VERSION to _POSIX_ outside the compat case.

<bits/syscall.h>: Use an arch-independent system call list on Linux This commit changes the way the list of SYS_* system call macros is created on Linux. glibc now contains a list of all known system calls, and the generated <bits/syscall.h> file defines the SYS_ macro only if the correspnding __NR_ macro is defined by the kernel headers. As a result, glibc does not have to be rebuilt to pick up system calls if the glibc sources already know about them. This means that glibc can be built with older kernel headers, and if the installed kernel headers are upgraded afterwards, additional SYS_ macros become available as long as glibc has a record for those system calls.

Remove powerpc32 sqrt wrappers. This patch removes the powerpc32-specific wrappers for sqrt and sqrtf. These wrappers, by adding architecture-specific uses of _LIB_VERSION and __kernel_standard, unnecessarily complicate cleanups of libm error handling. They also do not serve a useful optimization purpose. GCC knows about sqrt as a built-in function, and can generate direct calls to a hardware square root instruction, either on its own, in the -fno-math-errno case, or together with an inline check for the argument being negative and a call to the out-of-line sqrt function for error handling only in that case (and has been able to do so for a long time). Thus in practice the wrapper will only be called only in the case of negative arguments, which is not a case it is useful to optimize for.

Use __HAVE_DISTINCT_FLOAT128 in tgmath.h. When _Float128 is ABI-equivalent to long double, there is no need for tgmath.h to have any special _Float128 handling: it's always OK to call the long double versions of functions for _Float128 arguments in that case, and the logic to determine return types is generic. Thus, this patch changes the use of __HAVE_FLOAT128 to __HAVE_DISTINCT_FLOAT128, as a minor optimization to reduce the size of the macro expansions in the ABI-equivalent case. Tested for x86_64. * math/tgmath.h [__HAVE_FLOAT128]: Change conditional to [__HAVE_DISTINCT_FLOAT128].

Clean up bits/math-finite.h for aliasing types. This patch cleans up how bits/math-finite.h handles types that are ABI-aliases of other types. For such types, no __*_finite functions exist; instead, bits/math-finite.h must redirect calls to a the functions for a canonical choice of type for each floating-point format. (For the actual public interfaces, symbols need exporting for each type, even those that are ABI-aliases, because of standard requirements that programs can declare the functions themselves without including <math.h>, but that does not apply to __*_finite.) At present, there is a special-case conditional in bits/math-finite.h on __MATH_DECLARING_LDOUBLE && defined __NO_LONG_DOUBLE_MATH to handle redirecting long double function calls to double __*_finite. This patch replaces this by a more general mechanism. math.h, before each inclusion of bits/math-finite.h, defines _MSUFTO_ as the suffix to use on the target of redirection, in addition to the existing _MSUF_. This way, __MATH_DECLARING_LDOUBLE can go away, as can the special conditional in bits/math-finite.h. With this patch, math.h is now prepared for the case of supporting float128 functions as aliases of long double ones on platforms where long double is binary128, with _MSUFTO_ appropriately defined for that case, and appropriate _MSUFTO_ definitions can easily be included when supporting _Float32 / _Float64 / _Float32x / _Float64x (which will always be ABI-aliases of another type when supported).

Fix the C++ version of issignaling when __NO_LONG_DOUBLE_MATH is defined When __NO_LONG_DOUBLE_MATH is defined, __issignalingl is not available, thus issignaling with long double argument should call __issignaling, instead. Tested for powerpc64le. * math/math.h [defined __cplusplus] (issignaling): In the long double case, call __issignalingl only if __NO_LONG_DOUBLE_MATH is not defined. Call __issignaling, otherwise.

Remove cancellation support for syscall generation This patch removes the cancellation mark from the auto-generation syscall script. Now all the cancellable syscalls are done throught C code using the SYSCALL_CANCEL macro. It simplifies the assembly required to each architecture port, since the SYSCALL_CANCEL uses the already defined INLINE_SYSCALL macros, and allows a more straigh fix on cancellation machanism (since no more specific assembly fixes will be required). Checked on i686-linux-gnu, x86_64-linux-gnu, x86_64-linux-gnux32, aarch64-linux-gnu, arm-linux-gnueabihf, and powerpc64le-linux-gnu.A Also with build-many-glibc.py with remaning touched architectures. * sysdeps/unix/make-syscalls.sh: Remove cancellable tagging for syscall definitions. * sysdeps/unix/syscall-template.S (SYSCALL_CANCELLABLE): Remove definition. * sysdeps/unix/sysv/linux/aarch64/sysdep-cancel.h (PSEUDO): Remove definition.

Fix remaining return type of ifunc resolver declaration Since Martin Sebor's commit commit ee4e992ebe5f9712faedeefe8958b67d61eaa0f2 Author: Martin Sebor <msebor@redhat.com> Date: Tue Aug 22 09:35:23 2017 -0600 Declare ifunc resolver to return a pointer to the same type as the target function to help GCC detect incompatibilities between the two when it's enhanced to do so. builds for powerpc64le fail in the declaration of some ifunc resolvers, because the ifunc is declared with unmatching return types. One of the declarations comes from the __ifunc_resolver macro, which was patched by the aforementioned commit: /* Helper / base macros for indirect function symbols. */ #define __ifunc_resolver(type_name, name, expr, arg, init, classifier) \ classifier inhibit_stack_protector \ __typeof (type_name) *name##_ifunc (arg) \ whereas the other comes from the unpatched __ifunc macro when HAVE_GCC_IFUNC is not defined: # define __ifunc(type_name, name, expr, arg, init) \ extern __typeof (type_name) name; \ void *name##_ifunc (arg) __asm__ (#name); \ This patch changes the return type of the ifunc resolver in the __ifunc macro, so that it matches the return type of the target function, similarly to what the aforementioned commit does. Tested for powerpc64le and s390x with unpatched GCC. * include/libc-symbols.h: [!defined HAVE_GCC_IFUNC] (__ifunc): Change the return type of the ifunc resolver to match the return type of the target function.

Fix {INLINE,INTERNAL}_SYSCALL macros for x32 The problem for x32 is the {INTERNAL,INLINE}_SYSCALL C macros explicit cast the arguments to 'long int', thus passing as 32 bits arguments that should be passed to 64 bits. Previous x32 implementation uses the auto-generated syscalls from assembly macros (syscalls.list), so the {INTERNAL,INLINE}_SYSCALL macros are never used with 64 bit argument in x32 (which are internally broken for this ILP). To fix it I used a strategy similar to MIPS64n32 (although both ABI differs for some syscalls on how top pass 64-bits arguments) where argument types for kernel call are defined using GCC extension 'typeof' with a arithmetic operation. This allows 64-bits arguments to be defined while 32-bits argument will still passed as 32-bits. I also cleanup the {INLINE,INTERNAL}_SYSCALL definition by defining 'inline_syscallX' instead of constructing the argument passing using macros (it adds some readability) and removed the ununsed INTERNAL_SYSCALL_NCS_TYPES define (since the patch idea is exactly to avoid requiric explicit types passing).

Fix tgmath.h handling of complex integers (bug 21684). The tgmath.h macros return a real type not a complex type when an argument is of complex integer type (a GNU extension) and there are no arguments of complex floating type. It seems clear that just as real integers are mapped to double for tgmath.h, so complex integers should be mapped to _Complex double. This patch implements such a mapping. The main complication in fixing this bug is that the tgmath.h macros expand their arguments a large number of times, resulting in exponential blowup of the size of the expansion when calls to tgmath.h macros are used in the arguments of such macros; it would be unfortunate for fixing a bug with a fairly obscure extension to make the macros expand their arguments even more times. Thus, this patch optimizes the definitions of the relevant macros. __tgmath_real_type previously expanded its argument 7 times and now expands it 3 times. __tgmath_complex_type, used in place of __tgmath_real_type only for functions that might return either real or complex types, not for complex functions that always return real types or always return complex types, expands its argument 5 times. So the sizes of the macro expansions from nested macro calls are correspondingly reduced (remembering that each tgmath.h macro expands __tgmath_real_type, or sometimes now __tgmath_complex_type, several times). Sometimes the real return type resulted from calling a complex function and converting the result to a real type; sometimes it resulted from calling a real function, because the logic for determining whether arguments were real or complex, based on sizeof, was confused by integer promotions applying to e.g. short int but not _Complex short int. The relevant tests are converted to use a new macro __expr_is_real, which, by calling __builtin_classify_type rather than comparing the results of two calls to sizeof, also reduces the number of times macros expand their arguments. Although there are reductions in the number of times macros expand their arguments, I do not consider this to fix bug 21660, since a proper fix means each macro expanding its arguments only once (via using new compiler features designed for that purpose).

Provide a C++ version of issignaling that does not use __MATH_TG The macro __MATH_TG contains the logic to select between long double and _Float128, when these types are ABI-distinct. This logic relies on __builtin_types_compatible_p, which is not available in C++ mode. On the other hand, C++ function overloading provides the means to distinguish between the floating-point types. The overloading resolution will match the correct parameter regardless of type qualifiers, i.e.: const and volatile.

Fix position of tests-unsupported definition in assert/Makefile. tests-unsupported has to be defined before the inclusion of Rules in a subdirectory Makefile; otherwise it is ineffective. This patch fixes the ordering in assert/Makefile, where a recent test addition put tests-unsupported too late (resulting in build failures when the C++ compiler was missing or broken, and thereby showing up the unrelated bug 21987). Incidentally, I don't see why these tests depend on $(have-cxx-thread_local) rather than just a working C++ compiler.

Fix sparc32 bits/long-double.h (bug 21987). My refactoring of long double information commit 0acb8a2a855395c25b1feef2470f4d7ca4bed589 Author: Joseph Myers <joseph@codesourcery.com> Date: Wed Dec 14 18:27:56 2016 +0000 Refactor long double information into bits/long-double.h. resulted in sparc32 configurations installing the ldbl-opt version of bits/long-double.h instead of the intended sysdeps/unix/sysv/linux/sparc version. For sparc32 by itself, this is not a problem, since the ldbl-opt version is correct for sparc32. However, both sparc32 and sparc64 are supposed to install sets of headers that work for both of them, so that a single sysroot, whichever order the libraries are built and installed in, works for both. The effect of having the wrong version installed is that you end up with a miscompiled sparc64 libstdc++ which fails glibc's configure tests for the C++ compiler. This patch moves the header from sysdeps/unix/sysv/linux/sparc to separate copies of the same file for sparc32 and sparc64, to ensure it comes before ldbl-opt in the sysdeps directory ordering. Tested with build-many-glibcs.py for sparc64-linux-gnu and sparcv9-linux-gnu.

Fix position of tests-unsupported definition in assert/Makefile. tests-unsupported has to be defined before the inclusion of Rules in a subdirectory Makefile; otherwise it is ineffective. This patch fixes the ordering in assert/Makefile, where a recent test addition put tests-unsupported too late (resulting in build failures when the C++ compiler was missing or broken, and thereby showing up the unrelated bug 21987). Incidentally, I don't see why these tests depend on $(have-cxx-thread_local) rather than just a working C++ compiler. Tested in such a configuration (broken compiler/libstdc++) with build-many-glibcs.py. * assert/Makefile [$(have-cxx-thread_local)]: Move conditional variable definitions above inclusion of ../Rules.

Obsolete matherr, _LIB_VERSION, libieee.a. This patch obsoletes support for SVID libm error handling (the system where a user-defined function matherr is called on a libm function error; only enabled if you also set _LIB_VERSION = _SVID_ or _LIB_VERSION = _XOPEN_) and the use of the _LIB_VERSION global variable to control libm error handling. matherr and _LIB_VERSION are made into compat symbols, not supported for new ports or for static linking. The libieee.a object file (which sets _LIB_VERSION = _IEEE_, so disabling errno setting for some functions) is also removed, and all the related definitions are removed from math.h. The manual already recommends against using matherr, and it's already not supported for _Float128 functions (those use new wrappers that don't support matherr, only errno) - this patch means that it becomes possible to e.g. add sinf32 as an alias to sinf without that resulting in undesired matherr support in sinf32 for existing glibc ports. matherr support is not part of any standard supported by glibc (it was removed in XPG4). Because matherr is a function to be defined by the user, of course user programs defining such a function will still continue to link; it just quietly won't be used. If they try to write to the library's copy of _LIB_VERSION to enable SVID error handling, however, they will get a link error (but if they define their own _LIB_VERSION variable, they won't). I expect the most likely case of build failures from this patch to be programs with unconditional cargo-culted uses of -lieee (based on a notion of "I want IEEE floating point", not any actual requirement for that library). Ideally, the new-port-or-static-linking case would use the new wrappers used for _Float128. This is not implemented in this patch, because of the complication of architecture-specific (powerpc32 and sparc) sqrt wrappers that use _LIB_VERSION and __kernel_standard directly. Thus, the old wrappers and __kernel_standard are still built unconditionally, and _LIB_VERSION still exists in static libm. But when the old wrappers and __kernel_standard are built in the non-compat case, _LIB_VERSION and matherr are defined as macros so code to support those features isn't actually built into static libm or new ports' shared libm after this patch. I intend to move to the new wrappers for static libm and new ports in followup patches. I believe the sqrt wrappers for powerpc32 and sparc can reasonably be removed. GCC already optimizes the normal case of sqrt by generating code that uses a hardware instruction and only calls the sqrt function if the argument was negative (if -fno-math-errno, of course, it just uses the hardware instruction without any check for negative argument being needed). Thus those wrappers will only actually get called in the case of negative arguments, which is not a case it makes sense to optimize for. But even without removing the powerpc32 and sparc wrappers it should still be possible to move to the new wrappers for static libm and new ports, just without having those dubious architecture-specific optimizations in static libm. Everything said about matherr equally applies to matherrf and matherrl (IA64-specific, undocumented), except that the structure of IA64 libm means it won't be converted to using the new wrappers (it doesn't use the old ones either, but its own error-handling code instead). As with other tests of compat symbols, I expect test-matherr and test-matherr-2 to need to become appropriately conditional once we have a system for disabling such tests for ports too new to have the relevant symbols.

Remove SPARC sqrt wrappers (bug 21973). This patch removes the SPARC-specific wrappers for sqrt and sqrtf. These wrappers, by adding architecture-specific uses of _LIB_VERSION and __kernel_standard, unnecessarily complicate cleanups of libm error handling. They also do not serve a useful optimization purpose. GCC knows about sqrt as a built-in function, and can generate direct calls to a hardware square root instruction, either on its own, in the -fno-math-errno case, or together with an inline check for the argument being negative and a call to the out-of-line sqrt function for error handling only in that case (and has been able to do so for a long time). Thus in practice the wrapper will only be called only in the case of negative arguments, which is not a case it is useful to optimize for. The removal of the wrappers also uncovers, and fixes, an old bug. 32-bit SPARC libm used (checked with glibc 2.8 binaries) to have a sqrtl compat symbol, version GLIBC_2.0, for old binaries when sqrtl was an alias of sqrt (I don't have pre-glibc-2.4 binaries for SPARC to hand to check for the sqrtl symbol in those). This disappeared, probably with: commit 8847f0377003fbfe9cbe951ce9f8717d74f26247 Author: David S. Miller <davem@davemloft.net> Date: Tue Feb 28 22:37:58 2012 -0800 Add sparc optimized sqrt{,f}. Removing the wrappers brings back the generic ldbl-opt logic for creating such compat symbols, and so restores the compat symbol that should be there. This could of course also be fixed in the wrappers - but as noted above, the wrappers are optimizing a case it's not useful to optimize, so the bug of the missing compat symbol serves to illustrate the risks involved with the extra complexity of architecture-specific function versions where not needed.

I expect the most likely case of build failures from this patch to be programs with unconditional cargo-culted uses of -lieee (based on a notion of "I want IEEE floating point", not any actual requirement for that library). Ideally, the new-port-or-static-linking case would use the new wrappers used for _Float128. This is not implemented in this patch, because of the complication of architecture-specific (powerpc32 and sparc) sqrt wrappers that use _LIB_VERSION and __kernel_standard directly. Thus, the old wrappers and __kernel_standard are still built unconditionally, and _LIB_VERSION still exists in static libm. But when the old wrappers and __kernel_standard are built in the non-compat case, _LIB_VERSION and matherr are defined as macros so code to support those features isn't actually built into static libm or new ports' shared libm after this patch. I intend to move to the new wrappers for static libm and new ports in followup patches. I believe the sqrt wrappers for powerpc32 and sparc can reasonably be removed. GCC already optimizes the normal case of sqrt by generating code that uses a hardware instruction and only calls the sqrt function if the argument was negative (if -fno-math-errno, of course, it just uses the hardware instruction without any check for negative argument being needed). Thus those wrappers will only actually get called in the case of negative arguments, which is not a case it makes sense to optimize for. But even without removing the powerpc32 and sparc wrappers it should still be possible to move to the new wrappers for static libm and new ports, just without having those dubious architecture-specific optimizations in static libm. Everything said about matherr equally applies to matherrf and matherrl (IA64-specific, undocumented), except that the structure of IA64 libm means it won't be converted to using the new wrappers (it doesn't use the old ones either, but its own error-handling code instead). As with other tests of compat symbols, I expect test-matherr and test-matherr-2 to need to become appropriately conditional once we have a system for disabling such tests for ports too new to have the relevant symbols.

Do not use __builtin_types_compatible_p in C++ mode (bug 21930) The logic to define isinf for float128 depends on the availability of __builtin_types_compatible_p, which is only available in C mode, however, the conditionals do not check for C or C++ mode. This lead to an error in libstdc++ configure, as reported by bug 21930. This patch adds a conditional for C mode in the definition of isinf for float128. No definition is provided in C++ mode, since libstdc++ headers undefine isinf. Tested for powerpc64le (glibc test suite and libstdc++-v3 configure).

Add math benchmark latency test This patch further improves math function benchmarking by adding a latency test in addition to throughput. This enables more accurate comparisons of the math functions. The latency test works by creating a dependency on the previous iteration: func_res = F (func_res * zero + input[i]). The multiply by zero avoids changing the input. It reports reciprocal throughput and latency in nanoseconds (depending on the timing header used) and max/min throughput in iterations per second: "workload-spec2006.wrf": { "reciprocal-throughput": 100, "latency": 200, "max-throughput": 1.0e+07, "min-throughput": 5.0e+06 } * benchtests/bench-skeleton.c (main): Add support for latency benchmarking. * benchtests/scripts/bench.py: Add support for latency benchmarking.

Fix sigval namespace (bug 21944). XPG4.2 defines the siginfo_t type, but not union sigval or its contents (which were added in the 1993 edition of POSIX.1), resulting in namespace violations for sigval, sival_int and sival_ptr for signal.h and sys/wait.h for that standard because those headers incorrectly expose those names in that case. This patch fixes this problem. The public type in this case is union sigval, but various places in the headers use the sigval_t name for it; direct uses of union sigval are already properly guarded or in headers not in XPG4.2. Now, sigval_t, although not a standard name, does seem to be widely used outside glibc. The approach taken by this patch is to make installed headers use the name __sigval_t instead. __sigval_t is then defined to either union sigval or union __sigval (where union __sigval has __-prefixed member names as well), depending on whether there are any namespace issues with the union sigval name and its members. In the case where union __sigval is used, sigval_t is not defined at all, to avoid the problem of sigval_t having a C++ mangled name that depends on feature test macros. sigval_t is still defined by signal.h if __USE_MISC (reflecting the nonstandard nature of that name). Tested for x86_64.

Given my patch <https://gcc.gnu.org/ml/gcc-patches/2017-08/msg00965.html> for the ICEs building a glibc string function test for SH, the testsuite can build completely for SH with GCC 7 and mainline. However, there is a test failure that does not appear for GCC 6: check-localplt fails because of an abort PLT reference in libc.so. Given the lack of a trap insn pattern for SH, it seems unavoidable that the compiler might sometimes generate abort calls, and such abort calls (generated from __builtin_trap when there is no trap insn pattern) will be unaffected by the normal mapping to __GI_abort for calls within glibc. Thus, this patch allows (but does not require) an abort PLT reference in libc.so for SH. Tested for sh4-linux-gnu with build-many-glibcs.py (GCC 7, with my patch applied). * sysdeps/unix/sysv/linux/sh/localplt.data: Allow abort in libc.so.

NSS: Replace exported NSS lookup functions with stubs [BZ #21962] Commit 384ca551743318bd9c9e24a496d6397f2e3f2a49 from 2007 added this to nss/XXX-lookup.c: +#ifndef NO_COMPAT +int +internal_function attribute_compat_text_section +DB_COMPAT_FCT (service_user **ni, const char *fct_name, void **fctp) +{ + return DB_LOOKUP_FCT (ni, fct_name, NULL, fctp); +} +#endif That is, it adds a pseudo-compat function with an internal_function attribute. The function it was supposed to replace did not have the attribute: extern int DB_LOOKUP_FCT (service_user **ni, const char *fct_name, - void **fctp) internal_function; + const char *fct2_name, void **fctp) + internal_function; This changed the calling convention on i386 for the following functions in the public ABI: __nss_passwd_lookup __nss_group_lookup __nss_hosts_lookup This commit replaces the functions with always-failing stubs, with true compat symbols. Due to a happy accident, the calling convention of the stub is identical for the internal_function and non-internal_function case on i386. In addition, this commit auto-generates the __nss_*_lookup2 function declarations as part of <nsswitch.h>.

posix: Fix mmap for m68k and ia64 (BZ#21908) Default semantic for mmap2 syscall is to take the offset in 4096-byte units. However m68k and ia64 mmap2 implementation take in the configured pageunit units and for both architecture it can be different values. This patch fixes the m68k runtime discover of mmap2 offset unit and adds the ia64 definition to find it at runtime. Checked the basic tst-mmap and tst-mmap-offset on m68k (the system is configured with 4k, so current code is already passing on this system) and a sanity check on x86_64-linux-gnu (which should not be affected by this change). Sergei also states that ia64 loader now work correctly with this change.

i386: Do not set internal_function All calls to functions with the internal_function attribute have been removed from assembler implementations, which means that the definition of internal_function can be changed at the C level without causing ABI issues with assembler code. _dl_fixup still uses a regparm calling convention on i386, but this is controlled through ARCH_FIXUP_ATTRIBUTE, not internal_function.

powerpc: Restrict xssqrtqp operands to Vector Registers (bug 21941) POWER ISA 3.0 introduces the xssqrtqp instructions, which expects operands to be in Vector Registers (Altivec/VMX), even though this instruction belongs to the Vector-Scalar Instruction Set. In GCC's Extended Assembly for POWER, the 'wq' register constraint is provided for use with IEEE 754 128-bit floating-point values. However, this constraint does not limit the register allocation to Vector Registers (Altivec/VMX) and could assign a Vector-Scalar Register (VSX) to the operands of the instruction. This patch changes the register constraint used in sqrtf128 from 'wq' to 'v', in order to request a Vector Register (Altivec/VMX) for use with the xssqrtqp instruction. Tested for powerpc64le and --with-cpu=power9. [BZ #21941] * sysdeps/powerpc/fpu/math_private.h (__ieee754_sqrtf128): Since xssqrtqp requires operands to be in Vector Registers (Altivec/VMX), replace the register constraint 'wq' with 'v'. * sysdeps/powerpc/powerpc64le/power9/fpu/e_sqrtf128.c (__ieee754_sqrtf128): Likewise.

[AArch64] Optimized memcmp. This is an optimized memcmp for AArch64. This is a complete rewrite using a different algorithm. The previous version split into cases where both inputs were aligned, the inputs were mutually aligned and unaligned using a byte loop. The new version combines all these cases, while small inputs of less than 8 bytes are handled separately. This allows the main code to be sped up using unaligned loads since there are now at least 8 bytes to be compared. After the first 8 bytes, align the first input. This ensures each iteration does at most one unaligned access and mutually aligned inputs behave as aligned. After the main loop, process the last 8 bytes using unaligned accesses. This improves performance of (mutually) aligned cases by 25% and unaligned by >500% (yes >6 times faster) on large inputs. * sysdeps/aarch64/memcmp.S (memcmp): Rewrite of optimized memcmp.

Fix uc_* namespace (bug 21457). The standard members of ucontext_t, in all standard versions with that type, are uc_link, uc_sigmask, uc_stack and uc_mcontext. The uc_* namespace is mostly reserved for additions to the structure. However, in XPG4.2, it's only reserved when <ucontext.h> is included, not when <signal.h> is included, while <signal.h> is required to define ucontext_t (but not allowed to make visible other symbols from <ucontext.h>). Thus, nonstandard members should avoid uc_* names. Some already do use __uc_*, but others don't; most architectures (all except ia64, I think) have a member uc_flags and some have additional members beyond that. This patch makes nonstandard members have an __ prefix unless __USE_MISC is defined. Members whose names indicate they are solely padding / reserved for future use are renamed unconditionally to use the __glibc_reserved1 naming convention. This is part of the preparation for a revised version of the mcontext_t / sigcontext patch to be able to eliminate all 13 of the miscellaneous XFAILs in conform/Makefile, rather than only 11 of them as at present (at least one further fix on top of this one will be needed for that as well).

aarch64: Optimized memcpy for Qualcomm Falkor processor This is an optimized implementation of the memcpy routine that gives a significant gain in performance for all sizes of copies on the Qualcomm Falkor processor. A detailed rationale of the implementation is written in a comment in the patch. This implementation improves time for copies up to 128 bytes by up to 15% and for larger copies by up to 35% in the glibc microbenchmark. The memcpy-random benchmark sees improvements in all sizes in the range of 13%-18%. Here are the full numbers extracted from the glibc microbenchmark using the commands: ../benchtests/scripts/compare_strings.py benchtests/bench-memcpy.out \

* sysdeps/aarch64/multiarch/memcpy_falkor.S: Fix code style in
comments.
aarch64: Optimized memcpy for Qualcomm Falkor processor This is an optimized implementation of the memcpy routine that gives a significant gain in performance for all sizes of copies on the Qualcomm Falkor processor. A detailed rationale of the implementation is written in a comment in the patch. This implementation improves time for copies up to 128 bytes by up to 15% and for larger copies by up to 35% in the glibc microbenchmark. The memcpy-random benchmark sees improvements in all sizes in the range of 13%-18%. Here are the full numbers extracted from the glibc microbenchmark using the commands: ../benchtests/scripts/compare_strings.py benchtests/bench-memcpy.out \

manual: Document getcontext uc_stack value on Linux [BZ #759] As decribed in BZ#759, Linux getcontext implementation on Linux does differs from other SysV system about the returned uc_stack. This is true not only for i386, but for all the architecture I could actually check (aarch64, arm, alpha, hppa, m68k, mips, mips64, mips64n32, powerpc, powerpc64, powerpc64le, s390x, sh, sparc, sparc64, and x86). And I think we should not change current behavior for some reasons: 1. POSIX 2008 removed this SySV interface for a good reason and changing this behavior adds nothing for current portable code. POSIX 2001 specification does states that stack should be saved [1] and current GLIBC code does in a arch-specific manner (inside the mcontext_t) which allows the setcontext to work correctly. 2. Changing this behavior would potentially require compat symbols and I see no gain in adding compat symbols for deprecated interfaces. 3. Also, for comment #2 in BZ#759, it is up to kernel do setup the contents for ucontext_t and currently it does not provide the stack information as well. Trying to change it is also another fix that does not worth the possible gains. Instead my proposal is to make it clear the current interface may differ depending of the underlying operational system. glibc documentation and close this bug as invalid.

Do not use __ptr_t. sys/cdefs.h has a macro __ptr_t, which a few places in glibc use instead of void *. void * is a well-understood standard type for that purpose and in a post-C89 context there is no need for a macro for it; this patch changes those places to use void * directly instead. Unlike __long_double_t, __ptr_t is widely used outside glibc (or at least has many hits on codesearch.debian.net). I don't know how many of those uses would break if sys/cdefs.h ceased to define the macro, but there's enough risk that this patch leaves the definition and just removes the uses within glibc; removal of the definition can be considered separately if desired.

i386: Add <startup.h> [BZ #21913] On Linux/i386, there are 3 ways to make a system call: 1. call *%gs:SYSINFO_OFFSET. This requires TLS initialization. 2. call *_dl_sysinfo. This requires relocation of _dl_sysinfo. 3. int $0x80. This is slower than #2 and #3, but works everywhere. When an object file is compiled with PIC, #1 is prefered since it is faster than #3 and doesn't require relocation of _dl_sysinfo. For dynamic executables, ld.so initializes TLS. However, for static executables, before TLS is initialized by __libc_setup_tls, #3 should be used for system calls. This patch adds <startup.h> which defines _startup_fatal and defaults it to __libc_fatal. It replaces __libc_fatal with _startup_fatal in static executables where it is called before __libc_setup_tls is called. This header file is included in all files containing functions which are called before __libc_setup_tls is called. On Linux/i386, when PIE is enabled by default, _startup_fatal is turned into ABORT_INSTRUCTION and I386_USE_SYSENTER is defined to 0 so that "int $0x80" is used for system calls before __libc_setup_tls is called. Tested on i686 and x86-64. Without this patch, all statically-linked tests will fail on i686 when the compiler defaults to -fPIE. [BZ #21913] * csu/libc-tls.c: Include <startup.h> first.

posix: Set p{read,write}v2 to return ENOTSUP (BZ#21780) Different than other architectures hppa-linux-gnu define different values for ENOTSUP and EOPNOTSUPP, where the later is a Linux specific one.

Fix XPG4.2 bits/sigaction.h namespace (bug 21899). For XPG4.2, sa_sigaction, SA_ONSTACK, SA_RESETHAND, SA_RESTART and SA_NODEFER should be defined in signal.h, but they are only defined for other standards at present. This patch fixes the various bits/sigaction.h headers accordingly. All the fixes are essentially the same, except those for SPARC and Tile. For SPARC, the header (a) spuriously defined various nonstandard macros for __USE_UNIX98 || defined __USE_XOPEN2K8 and (b) defined some standard macros as aliases of nonstandard ones instead of the other way round. This patch fixes the SPARC header to handle these macros the same way and with the same conditions as those for other architectures, so the standard macros are the primary ones and the other ones are defined only for __USE_MISC and are aliases of the standard ones where applicable. For Tile, the header spuriously defined the nonstandard macro SA_NOPTRACE for __USE_UNIX98 || defined __USE_XOPEN2K8; this is moved to __USE_MISC. (Those nonstandard macros are in a reserved namespace, but it seems desirable to be consistent between architectures as far as possible, and so not define them in standard modes anywhere.)

Consistently use uintN_t not u_intN_t everywhere. This patch changes the remaining uses of the old nonstandard u_intN_t types in glibc to use the C99 uintN_t instead, except for the definitions of those typedefs and the tests of them in the c++-types test. This follows the previous such fix for libm, and being consistent in using uintN_t makes sense as a global cleanup.

Remove __long_double_t. sys/cdefs.h has a macro __long_double_t used in two places in glibc. long double is a standard part of C since C89; there is no need for such an alias for it. This patch removes that macro and uses long double directly everywhere. As an implementation-namespace, undocumented symbol, it should not be considered part of the API for users, and codesearch.debian.net shows no sign of it being used outside glibc in a way that would break with this patch. Tested for x86_64. * misc/sys/cdefs.h (__long_double_t): Remove. * stdio-common/printf_fp.c (__printf_fp_l): Use long double instead of __long_double_t, * stdlib/strfmon_l.c (__vstrfmon_l): Likewise.

Consistently use uintN_t not u_intN_t in libm. This patch changes libm code to make consistent use of C99 uintN_t types instead of sometimes using those and sometimes using the older nonstandard u_intN_t names. This makes sense as a cleanup in its own right, and also facilitates merges to GCC's libquadmath (which gets the types from stdint.h and so may not have u_intN_t available at all).

tst-tlsopt-powerpc as a shared lib This makes the __tls_get_addr_opt test run as a shared library, and so actually test that DTPMOD64/DTPREL64 pairs are processed by ld.so to support the __tls_get_adfr_opt call stub fast return. After a 2017-01-24 patch (binutils f0158f4416) ld.bfd no longer emitted unnecessary dynamic relocations against local thread variables, instead setting up the __tls_index GOT entries for the call stub fast return. This meant tst-tlsopt-powerpc passed but did not check ld.so relocation support. After a 2017-07-16 patch (binutils 676ee2b5fa) ld.bfd no longer set up the __tls_index GOT entries for the call stub fast return, and tst-tlsopt-powerpc failed. Compiling mod-tlsopt-powerpc.c with -DSHARED exposed a bug in powerpc64/tls-macros.h, which defines a __TLS_GET_ADDR macro that clashes with one defined in dl-tls.h. The tls-macros.h version is only used in that file, so delete it and expand. * sysdeps/powerpc/mod-tlsopt-powerpc.c: Extract from tst-tlsopt-powerpc.c with function name change and no test harness. * sysdeps/powerpc/tst-tlsopt-powerpc.c: Remove body of test.

Fix tgmath.h for __int128 (bug 21686). When a tgmath.h macro is passed a double argument and an argument of type __int128, it generates a call to a long double function (although the result still gets converted to type double). __int128 is similar enough to integer types that it should be handled consistently like them, so always like double for these macros rather than sometimes like double and sometimes like long double. This patch fixes the logic accordingly and makes gen-tgmath-tests.py generate tests for __int128. Tested for x86_64 and x86.

Fix tgmath.h for bit-fields (bug 21685). The tgmath.h macros produce errors for bit-field arguments, because they apply sizeof and typeof to the arguments. This patch fixes them to use unary + systematically before using sizeof or typeof on arguments that might be bit-fields (note that __real__ of a bit-field is still a bit-field for this purpose, since it's an lvalue). gen-tgmath-tests.py is extended to add tests for this case.
