5e4e10636c Miscellaneous low-risk changes preparing for _ISOMAC testsuite. 
These are a grab bag of changes where the testsuite was using internal
symbols of some variety, but this was straightforward to fix, and the
fixed code should work with or without the change to compile the
testsuite under _ISOMAC.

Four of these are just more #include adjustments, but I want to highlight
sysdeps/powerpc/fpu/tst-setcontext-fpscr.c, which appears to have been
written before the advent of sys/auxv.h.  I think a big chunk of this file
could be replaced by a simple call to getauxval, but I'll let someone who
actually has a powerpc machine to test on do that.

dlfcn/tst-dladdr.c was including ldsodefs.h just so it could use
DL_LOOKUP_ADDRESS to print an additional diagnostic; as requested by Carlos,
I have removed this.

math/test-misc.c was using #ifndef NO_LONG_DOUBLE, which is an internal
configuration macro, to decide whether to do certain tests involving
'long double'.  I changed the test to #if LDBL_MANT_DIG > DBL_MANT_DIG
instead, which uses only public float.h macros and is equivalent on
all supported platforms.  (Note that NO_LONG_DOUBLE doesn't mean 'the
compiler doesn't support long double', it means 'long double is the
same as double'.)

tst-writev.c has a configuration macro 'ARTIFICIAL_LIMIT' that the
Makefiles are expected to define, and sysdeps/unix/sysv/linux/Makefile
was using the internal __getpagesize in the definition; changed to
sysconf(_SC_PAGESIZE) which is the POSIX equivalent.

ia64-linux doesn't supply 'clone', only '__clone2', which is not
defined in the public headers(!)  All the other clone tests have local
extern declarations of __clone2, but tst-clone.c doesn't; it was
getting away with this because include/sched.h does declare __clone2.

	* nss/tst-cancel-getpwuid_r.c: Include nss.h.
	* string/strcasestr.c: No need to include config.h.
	* sysdeps/powerpc/fpu/tst-setcontext-fpscr.c: Include
	sys/auxv.h. Don't include sysdep.h.
	* sysdeps/powerpc/tst-set_ppr.c: Don't include dl-procinfo.h.

	* dlfcn/tst-dladdr.c: Don't include ldsodefs.h.	 Don't use
	DL_LOOKUP_ADDRESS.
	* math/test-misc.c: Instead of testing NO_LONG_DOUBLE, test whether
	LDBL_MANT_DIG is greater than DBL_MANT_DIG.
	* sysdeps/unix/sysv/linux/Makefile (CFLAGS-tst-writev.c): Use
	sysconf (_SC_PAGESIZE) instead of __getpagesize in definition
	of ARTIFICIAL_LIMIT.
	* sysdeps/unix/sysv/linux/tst-clone.c [__ia64__]: Add extern
	declaration of __clone2.

c23de0aacb support: Introduce new subdirectory for test infrastructure 
The new test driver in <support/test-driver.c> has feature parity with
the old one.  The main difference is that its hooking mechanism is
based on functions and function pointers instead of macros.  This
commit also implements a new environment variable, TEST_COREDUMPS,
which disables the code which disables coredumps (that is, it enables
them if the invocation environment has not disabled them).

<test-skeleton.c> defines wrapper functions so that it is possible to
use existing macros with the new-style hook functionality.

This commit changes only a few test cases to the new test driver, to
make sure that it works as expected.

9e78f6f6e7 Implement _dl_catch_error, _dl_signal_error in libc.so [BZ #16628] 
This change moves the main implementation of _dl_catch_error,
_dl_signal_error to libc.so, where TLS variables can be used
directly.  This removes a writable function pointer from the
rtld_global variable.

For use during initial relocation, minimal implementations of these
functions are provided in ld.so.  These are eventually interposed
by the libc.so implementations.  This is implemented by compiling
elf/dl-error-skeleton.c twice, via elf/dl-error.c and
elf/dl-error-minimal.c.

As a side effect of this change, the static version of dl-error.c
no longer includes support for the
_dl_signal_cerror/_dl_receive_error mechanism because it is only
used in ld.so.

1b16ff0b1e Fix warning caused by unused-result in bug-atexit3-lib.cc 
The test case dlfcn/bug-atexit3-lib.cc calls write and doesn't check the
result.  When building with GCC 6.2, this generates a warning in 'make
check', which is treated as an error.  This patch replaces the call to
write with a call to write_message.

Tested for powerpc64le.

b5537473c2 tst-rec-dlopen: Fix build fail due to missing inclusion of string.h 
on S390, I get a compile error for dlfcn/tst-rec-dlopen.c:

b4f518ecfa Fix building glibc master with NDEBUG and --with-cpu. 
When building on i686, x86_64, and arm, and with NDEBUG, or --with-cpu
there are various variables and functions which are unused based on
these settings.

This patch marks all such variables with __attribute__((unused)) to
avoid the compiler warnings when building with the aformentioned
options.

ec999b8e5e Move bits/libc-lock.h and bits/libc-lockP.h out of bits/ (bug 14912). 
It was noted in
<https://sourceware.org/ml/libc-alpha/2012-09/msg00305.html> that the
bits/*.h naming scheme should only be used for installed headers.
This patch renames bits/libc-lock.h to plain libc-lock.h and
bits/libc-lockP.h to plain libc-lockP.h to follow that convention.

Note that I don't know where libc-lockP.h comes from for Hurd (the
Hurd libc-lock.h includes libc-lockP.h, but the only libc-lockP.h in
the glibc source tree is for NPTL) - some unmerged patch? - but I
updated the #include in the Hurd libc-lock.h anyway.

Tested for x86_64 (testsuite, and that installed stripped shared
libraries are unchanged by the patch).

ccdb048df4 Fix recursive dlopen. 
The ability to recursively call dlopen is useful for malloc
implementations that wish to load other dynamic modules that
implement reentrant/AS-safe functions to use in their own
implementation.

Given that a user malloc implementation may be called by an
ongoing dlopen to allocate memory the user malloc
implementation interrupts dlopen and if it calls dlopen again
that's a reentrant call.

This patch fixes the issues with the ld.so.cache mapping
and the _r_debug assertion which prevent this from working
as expected.

9114625bad Fix dlfcn/failtestmod.c warning. 
This patch fixes a "set but not used" warning from
dlfcn/failtestmod.c.  A variable is used only to store the return
value from dlsym.  As I understand this test, the point is simply to
do a sequence of load / unload operations in a loop, and all that
matters here is that dlsym gets called and returns without crashing,
not what its return value is.  So this patch removes the assignment to
a variable.

Tested for x86_64.

	* dlfcn/failtestmod.c (constr): Do not store result of dlsym in a
	variable.

Barring libc.so and libdl.so, none of the libraries have any entry
points, so it is pointless to add a .interp section for them.  The
libdl.so entry point (in dlfcn/eval.c) is also defunct, so remove that
file as well.

Build tested for x86_64, ppc64 and s390x.  I have not moved
CFLAGS-interp.c to CPPFLAGS-interp.c isnce I'll be removing it
completely in a follow-up patch.

f08e9a2629 Fix fallout from Joseph's untested Makeconfig change. 2014-02-28 13:00:27 -08:00
Joseph Myers
a5f891ac8d Consistently include Makeconfig after defining subdir. 
In <https://sourceware.org/ml/libc-alpha/2014-01/msg00196.html> I
noted it was necessary to add includes of Makeconfig early in various
subdirectory makefiles for the tests-special variable settings added
by that patch to be conditional on configuration information.  No-one
commented on the general question there of whether Makeconfig should
always be included immediately after the definition of subdir.

This patch implements that early inclusion of Makeconfig in each
directory (which is a lot easier than consistent placement of includes
of Rules).  Includes are added if needed, or moved up if already
present.  Subdirectory "all:" targets are removed, since Makeconfig
provides one.

There is potential for further cleanups I haven't done.  Rules and
Makerules have code such as

ifneq   "$(findstring env,$(origin headers))" ""
headers :=
endif

to override to empty any value of various variables that came from the
environment.  I think there is a case for Makeconfig setting all the
subdirectory variables (other than subdir) to empty to ensure no
outside value is going to take effect if a subdirectory fails to
define a variable.  (A list of such variables, possibly out of date
and incomplete, is in manual/maint.texi.)  Rules and Makerules would
give errors if Makeconfig hadn't already been included, instead of
including it themselves.  The special code to override values coming
from the environment would then be obsolete and could be removed.

Tested x86_64, including that installed binaries are identical before
and after the patch.

3b813b2965 [BZ #15897] dlfcn: do not mark dlopen/dlclose as leaf functions 
Since the dlopen funcs might invoke a constructor that calls a func
that is in the same compilation unit as the caller, we cannot mark
them as leaf funcs.

Similarly, dlclose might invoke a destructor that calls a func that
is in the same compilation unit as the caller.

f91f1c0fb8 [BZ #15022] Correct global-scope dlopen issues in static executables. 
This change creates a link map in static executables to serve as the
global search list for dlopen.  It fixes a problem with the inability
to access the global symbol object and a crash on an attempt to map a
DSO into the global scope.  Some code that has become dead after the
addition of this link map is removed too and test cases are provided.
