gdb: remove TYPE_FIELD_TYPE macro
Remove the `TYPE_FIELD_TYPE` macro, changing all the call sites to use `type::field` and `field::type` directly. gdb/ChangeLog: * gdbtypes.h (TYPE_FIELD_TYPE): Remove. Change all call sites to use type::field and field::type instead. Change-Id: Ifda6226a25c811cfd334a756a9fbc5c0afdddff3 |

gdb: remove TYPE_NFIELDS macro
Remove `TYPE_NFIELDS`, changing all the call sites to use `type::num_fields` directly. This is quite a big diff, but this was mostly done using sed and coccinelle. A few call sites were done by hand. gdb/ChangeLog: * gdbtypes.h (TYPE_NFIELDS): Remove. Change all cal sites to use type::num_fields instead. Change-Id: Ib73be4c36f9e770e0f729bac3b5257d7cb2f9591 |

gdb: add type::name / type::set_name
Add the `name` and `set_name` methods on `struct type`, in order to remove the `TYPE_NAME` macro. In this patch, the `TYPE_NAME` macro is changed to use `type::name`, so all the call sites that are used to set the type name are changed to use `type::set_name`. The next patch will remove `TYPE_NAME` completely. gdb/ChangeLog: * gdbtypes.h (struct type) <name, set_name>: New methods. (TYPE_CODE): Use type::name. Change all call sites used to set the name to use type::set_name instead. |

Use thiscall calling convention for class members
Non-static member functions for Windows 32bit programs need the thiscall calling convention, so the 'this' pointer needs to be passed in ECX. gdb/ChangeLog: 2020-04-30 Hannes Domani <ssbssa@yahoo.de> PR gdb/15559 * i386-tdep.c (i386_push_dummy_call): Call i386_thiscall_push_dummy_call.

Replace most calls to help_list and cmd_show_list
Currently there are many prefix commands that do nothing but call either help_list or cmd_show_list. I happened to notice that one such call, for "set print type", used the wrong command list parameter, causing incorrect output. Rather than fix this bug in isolation, I decided to eliminate this possibility by adding two new ways to add prefix commands, which simply route the call to help_list or cmd_show_list, as appropriate. This makes it impossible for a mismatch to occur. In some cases, a bit of output was removed; however, I don't think this output in general was very useful. It seemed redundant with what's already printed by help_list. A representative example is this hunk, removed from ada-lang.c: - printf_unfiltered (_(\ -"\"set ada\" must be followed by the name of a setting.\n")); This simplified the CLI style set/show commands quite a bit, and allowed the deletion of a macro. This also cleans up some unusual code in windows-tdep.c. Tested on x86-64 Fedora 30. Note that I have no way to build the go32-nat.c change. gdb/ChangeLog 2020-04-17 Tom Tromey <tromey@adacore.com> * auto-load.c (show_auto_load_cmd): Remove.

gdb: make gdbarch_displaced_step_copy_insn return an std::unique_ptr

gdb: add back declarations for _initialize functions
I'd like to enable the -Wmissing-declarations warning. However, it
warns for every _initialize function, for example:
CXX dcache.o
/home/smarchi/src/binutils-gdb/gdb/dcache.c: In function ‘void _initialize_dcache()’:
/home/smarchi/src/binutils-gdb/gdb/dcache.c:688:1: error: no previous declaration for ‘void _initialize_dcache()’ [-Werror=missing-declarations]
_initialize_dcache (void)
^~~~~~~~~~~~~~~~~~
The only practical way forward I found is to add back the declarations,
which were removed by this commit:

gdb: Remove a non-const reference parameter
Non-const reference parameter should be avoided according to the GDB coding standard: https://sourceware.org/gdb/wiki/Internals%20GDB-C-Coding-Standards#Avoid_non-const_reference_parameters.2C_use_pointers_instead This commit updates the gdbarch method gdbarch_stap_adjust_register, and the one implementation i386_stap_adjust_register to avoid using a non-const reference parameter. I've also removed the kfail from the testsuite for bug 24541, as this issue is now resolved. gdb/ChangeLog: PR breakpoints/24541 * gdbarch.c: Regenerate. * gdbarch.h: Regenerate. * gdbarch.sh: Adjust return type and parameter types for 'stap_adjust_register'.

Rename common to gdbsupport
This is the next patch in the ongoing series to move gdbsever to the top level. This patch just renames the "common" directory. The idea is to do this move in two parts: first rename the directory (this patch), then move the directory to the top. This approach makes the patches a bit more tractable. I chose the name "gdbsupport" for the directory. However, as this patch was largely written by sed, we could pick a new name without too much difficulty.

i386/AArch64: Remove old xml tests
Both the i386, X86_64 and AArch64 builds of gdbserver include a bunch of legacy xml files, dat files and auto generated C files, when building for unit test. These tests exists back from when feature target descriptions were added to prove that the new target descriptions were identical to the original older versions. The old files are not used for anything other than these tests. Now that this has been proven, we are not gaining anything by keeping the original files and tests. Should new functionality be added, it would break the tests, unless the functionality was backported to the xml. There is no requirement that we must match the exact xml from N releases ago. It adds obfuscation, where as the feature target descriptions were meant to simplify the code. In addition, there are a bunch of xml and dat files which are completely unused. This patch removes the selftests and the target descriptions from gdbserver. Update the unittest to allow 0 tests (note, this failed on other targets that never had any tests). gdb/ChangeLog: * aarch64-tdep.c: Remove xml self tests. * amd64-linux-tdep.c: Likewise. * amd64-tdep.c: Likewise. * i386-linux-tdep.c: Likewise. * i386-tdep.c: Likewise. gdb/gdbserver/ChangeLog: * configure.srv: Remove legacy xml. * linux-aarch64-low.c (initialize_low_arch): Remove initialize_low_tdesc call. * linux-aarch64-tdesc-selftest.c: Remove file. * linux-aarch64-tdesc.h (initialize_low_tdesc): Remove. * linux-x86-low.c (initialize_low_arch): Remove initialize_low_tdesc call. * linux-x86-tdesc-selftest.c: Remove file. * linux-x86-tdesc.h (initialize_low_tdesc): Remove. gdb/testsuite/ChangeLog: * gdb.server/unittest.exp: Allow 0 unit tests to run. |

Adjust i386 registers on SystemTap probes' arguments (PR breakpoints/24541)
This bug has been reported on PR breakpoints/24541, but it is possible to reproduce it easily by running: make check-gdb TESTS=gdb.base/stap-probe.exp RUNTESTFLAGS='--target_board unix/-m32' The underlying cause is kind of complex, and involves decisions made by GCC and the sys/sdt.h header file about how to represent a probe argument that lives in a register in 32-bit programs. I'll use Andrew's example on the bug to illustrate the problem. libstdc++ has a probe named "throw" with two arguments. On i386, the probe is: stapsdt 0x00000028 NT_STAPSDT (SystemTap probe descriptors) Provider: libstdcxx Name: throw Location: 0x00072c96, Base: 0x00133d64, Semaphore: 0x00000000 Arguments: 4@%si 4@%di I.e., the first argument is an unsigned 32-bit value (represented by the "4@") that lives on %si, and the second argument is an unsigned 32-bit value that lives on %di. Note the discrepancy between the argument size reported by the probe (32-bit) and the register size being used to store the value (16-bit). However, if you take a look at the disassemble of a program that uses this probe, you will see: 00072c80 <__cxa_throw@@CXXABI_1.3>: 72c80: 57 push %edi 72c81: 56 push %esi 72c82: 53 push %ebx 72c83: 8b 74 24 10 mov 0x10(%esp),%esi 72c87: e8 74 bf ff ff call 6ec00 <__cxa_finalize@plt+0x980> 72c8c: 81 c3 74 e3 10 00 add $0x10e374,%ebx 72c92: 8b 7c 24 14 mov 0x14(%esp),%edi 72c96: 90 nop <----------------- PROBE IS HERE 72c97: e8 d4 a2 ff ff call 6cf70 <__cxa_get_globals@plt> 72c9c: 83 40 04 01 addl $0x1,0x4(%eax) 72ca0: 83 ec 04 sub $0x4,%esp 72ca3: ff 74 24 1c pushl 0x1c(%esp) 72ca7: 57 push %edi 72ca8: 56 push %esi 72ca9: e8 62 a3 ff ff call 6d010 <__cxa_init_primary_exception@plt> 72cae: 8d 70 40 lea 0x40(%eax),%esi 72cb1: c7 00 01 00 00 00 movl $0x1,(%eax) 72cb7: 89 34 24 mov %esi,(%esp) 72cba: e8 61 96 ff ff call 6c320 <_Unwind_RaiseException@plt> 72cbf: 89 34 24 mov %esi,(%esp) 72cc2: e8 c9 84 ff ff call 6b190 <__cxa_begin_catch@plt> 72cc7: e8 d4 b3 ff ff call 6e0a0 <_ZSt9terminatev@plt> 72ccc: 66 90 xchg %ax,%ax 72cce: 66 90 xchg %ax,%ax Note how the program is actually using %edi, and not %di, to store the second argument. This is the problem here. GDB will basically read the probe argument, then read the contents of %di, and then cast this value to uint32_t, which causes the wrong value to be obtained. In the gdb.base/stap-probe.exp case, this makes GDB read the wrong memory location, and not be able to display a test string. In Andrew's example, this causes GDB to actually stop at a "catch throw" when it should actually have *not* stopped. After some discussion with Frank Eigler and Jakub Jelinek, it was decided that this bug should be fixed on the client side (i.e., the program that actually reads the probes), and this is why I'm proposing this patch. The idea is simple: we will have a gdbarch method, which, for now, is only used by i386. The generic code that deals with register operands on gdb/stap-probe.c will call this method if it exists, passing the current parse information, the register name and its number. The i386 method will then verify if the register size is greater or equal than the size reported by the stap probe (the "4@" part). If it is, we're fine. Otherwise, it will check if we're dealing with any of the "extendable" registers (like ax, bx, si, di, sp, etc.). If we are, it will change the register name to include the "e" prefix. I have tested the patch here in many scenarios, and it fixes Andrew's bug and also the regressions I mentioned before, on gdb.base/stap-probe.exp. No regressions where found on other tests.

gdb/fortran: Use floatformats_ia64_quad for fortran 16-byte floats
PR gdb/18644 is caused by GDB using the wrong floating point format for gfortran's 16-byte floating point type, including when the 16-byte float is used as the component of a 32-byte complex type. This commit addresses the issue in two places, first in i386-tdep.c, there is already some code to force the use of floatformats_ia64_quad for specific named types, this is extended to include the type names that gfortran uses for its 16-byte floats. Second, the builtin 16-byte float type (in f-lang.c) is changed so it no longer uses gdbarch_long_double_format. On i386 this type is not 16-bytes, but is smaller, this is not what gfortran is expecting. Instead we now use gdbarch_floatformat_for_type and ask for a 16-byte (128 bit) type using the common gfortran type name. This is then spotted in i386-tdep.c (thanks to the first change above) and we again get floatformats_ia64_quad returned. This patch was tested on X86-64/GNU-Linux using '--target_board=unix' and '--target_board=unix/-m32', and resolves all of the known failures associated with PR gdb/18644. I've also added the test case from the original bug report. gdb/ChangeLog: PR gdb/18644: * f-lang.c (build_fortran_types): Use floatformats_ia64_quad for 16-byte floats. * i386-tdep.c (i386_floatformat_for_type): Use floatformats_ia64_quad for the 16-byte floating point component within a fortran 32-byte complex number. gdb/testsuite/ChangeLog: PR gdb/18644 * gdb.fortran/complex.exp: Remove setup_kfail calls. * gdb.fortran/printing-types.exp: Add new test. * gdb.fortran/printing-types.f90: Add 16-byte real variable for testing. * gdb.fortran/type-kinds.exp (test_cast_1_to_type_kind): Remove setup_kfail call. |

Replace throw_exception with throw in some cases
This replaces throw_exception with "throw;" when possible. This was written by script. The rule that is followed is that uses of the form: catch (... &name) { ... throw_exception (name); } ... can be rewritten.

gdb: Restructure type_align and gdbarch_type_align
This commit restructures the relationship between the type_align function and the gdbarch_type_align method. The problem being addressed with this commit is this; previously the type_align function was structured so that for "basic" types (int, float, etc) the gdbarch_type_align hook was called, which for "compound" types (arrays, structs, etc) the common type_align code has a fixed method for how to extract a "basic" type and would then call itself on that "basic" type. The problem is that if an architecture wants to modify the alignment rules for a "compound" type then this is not currently possible. In the revised structure, all types pass through the gdbarch_type_align method. If this method returns 0 then this indicates that the architecture has no special rules for this type, and GDB should apply the default rules for alignment. However, the architecture is free to provide an alignment for any type, both "basic" and "compound". After this commit the default alignment rules now all live in the type_align function, the default_type_align only ever returns 0, meaning apply the default rules. I've updated the 3 targets (arc, i386, and nios2) that already override the gdbarch_type_align method to fit the new scheme. Tested on X86-64/GNU Linux with no regressions. gdb/ChangeLog: * arc-tdep.c (arc_type_align): Provide alignment for basic types, return 0 for other types. * arch-utils.c (default_type_align): Always return 0. * gdbarch.h: Regenerate. * gdbarch.sh (type_align): Extend comment. * gdbtypes.c (type_align): Add additional comments, always call gdbarch_type_align before applying the default rules. * i386-tdep.c (i386_type_align): Return 0 as the default rule, generic code will then apply a suitable default. * nios2-tdep.c (nios2_type_align): Provide alignment for basic types, return 0 for other types. |

Update copyright year range in all GDB files.
This commit applies all changes made after running the gdb/copyright.py script. Note that one file was flagged by the script, due to an invalid copyright header (gdb/unittests/basic_string_view/element_access/char/empty.cc). As the file was copied from GCC's libstdc++-v3 testsuite, this commit leaves this file untouched for the time being; a patch to fix the header was sent to gcc-patches first. gdb/ChangeLog: Update copyright year range in all GDB files. |

Introduce gdbarch_num_cooked_regs
The expression gdbarch_num_regs (gdbarch) + gdbarch_num_pseudo_regs (gdbarch) is used quite often to find the number of cooked registers (raw + pseudo registers). This patch introduces gdbarch_num_cooked_regs, which does the equivalent. It substantially reduces required wrapping in some places, so should improve readability. There is a for loop in m68hc11_frame_unwind_cache that had iterated until (the equivalent of) gdbarch_num_cooked_regs (gdbarch) - 1. During review, we concluded that this is most likely an off-by-one mistake, so I replaced it with gdbarch_num_cooked_regs (gdbarch). gdb/ChangeLog: * gdbarch.sh (gdbarch_num_cooked_regs): New. * gdbarch.h: Re-generate. * ax-gdb.c (gen_expr): Use gdbarch_num_cooked_regs. * dwarf2-frame.c (dwarf2_frame_cache): Likewise. * eval.c (evaluate_subexp_standard): Likewise. * findvar.c (value_of_register): Likewise.

Split size in regset section iterators
In the existing code, when using the regset section iteration functions, the size parameter is used in different ways. With collect, size is used to create the buffer in which to write the regset. (see linux-tdep.c::linux_collect_regset_section_cb). With supply, size is used to confirm the existing regset is the correct size. If REGSET_VARIABLE_SIZE is set then the regset can be bigger than size. Effectively, size is the minimum possible size of the regset. (see corelow.c::get_core_register_section). There are currently no targets with both REGSET_VARIABLE_SIZE and a collect function. In SVE, a corefile can contain one of two formats after the header, both of which are different sizes.

Remove long_long_align_bit gdbarch attribute
This removes the long_long_align_bit gdbarch attribute in favor of type_align. This uncovered two possible issues. First, arc-tdep.c claimed that long long alignment was 32 bits, but as discussed on the list, ARC has a maximum alignment of 32 bits, so I've added an arc_type_align function to account for this. Second, jit.c, the sole user of long_long_align_bit, was confusing "long long" with uint64_t. The relevant structure is defined in the JIT API part of the manual as: struct jit_code_entry { struct jit_code_entry *next_entry; struct jit_code_entry *prev_entry; const char *symfile_addr; uint64_t symfile_size; }; I've changed this code to use uint64_t. 2018-04-30 Tom Tromey <tom@tromey.com> * jit.c (jit_read_code_entry): Use type_align. * i386-tdep.c (i386_gdbarch_init): Don't call set_gdbarch_long_long_align_bit. * gdbarch.sh: Remove long_long_align_bit. * gdbarch.c, gdbarch.h: Rebuild. * arc-tdep.c (arc_type_align): New function.

infrun: step through indirect branch thunks
With version 7.3 GCC supports new options -mindirect-branch=<choice> -mfunction-return=<choice> The choices are: keep behaves as before thunk jumps through a thunk thunk-external jumps through an external thunk thunk-inline jumps through an inlined thunk For thunk and thunk-external, GDB would, on a call to the thunk, step into the thunk and then resume to its caller assuming that this is an undebuggable function. On a return thunk, GDB would stop inside the thunk. Make GDB step through such thunks instead. Before: Temporary breakpoint 1, main () at gdb.base/step-indirect-call-thunk.c:37 37 x = apply (inc, 41); (gdb) s apply (op=0x80483e6 <inc>, x=41) at gdb.base/step-indirect-call-thunk.c:29 29 return op (x); (gdb) 30 } After: Temporary breakpoint 1, main () at gdb.base/step-indirect-call-thunk.c:37 37 x = apply (inc, 41); (gdb) s apply (op=0x80483e6 <inc>, x=41) at gdb.base/step-indirect-call-thunk.c:29 29 return op (x); (gdb) inc (x=41) at gdb.base/step-indirect-call-thunk.c:23 23 return x + 1; This is independent of the step-mode. In order to step into the thunk, you would need to use stepi. When stepping over an indirect call thunk, GDB would first step through the thunk, then recognize that it stepped into a sub-routine and resume to the caller (of the thunk). Not sure whether this is worth optimizing. Thunk detection is implemented via gdbarch. I implemented the methods for IA. Other architectures may run into unexpected fails. The tests assume a fixed number of instruction steps to reach a thunk. This depends on the compiler as well as the architecture. They may need adjustments when we add support for more architectures. Or we can simply drop those tests that cover being able to step into thunks using instruction stepping. When using an older GCC, the tests will fail to build and will be reported as untested: Running .../gdb.base/step-indirect-call-thunk.exp ... gdb compile failed, \ gcc: error: unrecognized command line option '-mindirect-branch=thunk' gcc: error: unrecognized command line option '-mfunction-return=thunk' === gdb Summary === # of untested testcases 1 gdb/ * infrun.c (process_event_stop_test): Call gdbarch_in_indirect_branch_thunk. * gdbarch.sh (in_indirect_branch_thunk): New. * gdbarch.c: Regenerated. * gdbarch.h: Regenerated. * x86-tdep.h: New. * x86-tdep.c: New. * Makefile.in (ALL_TARGET_OBS): Add x86-tdep.o.

class readable_regcache and pass readable_regcache to gdbarch pseudo_register_read and pseudo_register_read_value
pseudo registers are either from raw registers or memory, so gdbarch methods pseudo_register_read and pseudo_register_read_value should have regcache object which only have read methods. In other words, we should disallow writing to regcache in these two gdbarch methods. In order to apply this restriction, this patch adds a new class readable_regcache, derived from reg_buffer, and it only has raw_read and cooked_read methods. regcache is derived from readable_regcache. This patch also passes readable_regcache instead of regcache to gdbarch methods pseudo_register_read and pseudo_register_read_value. This patch moves raw_read* and cooked_read* methods to readable_regcache, which is straightforward. One thing not straightforward is that I split regcache::xfer_part to readable_regcache::read_part and regcache::write_part, because readable_regcache can only have methods to read. readable_regcache is an abstract base class, and it has a pure virtual function raw_update, because I don't want readable_regcache know where these raw registers are from. They can be from either the target (readwrite regcache) or the regcache itself (readonly regcache). gdb: 2018-02-21 Yao Qi <yao.qi@linaro.org> * aarch64-tdep.c (aarch64_pseudo_register_read_value): Change parameter type to 'readable_regcache *'. * amd64-tdep.c (amd64_pseudo_register_read_value): Likewise. * arm-tdep.c (arm_neon_quad_read): Likewise.

Target FP: Remove convert_typed_floating from tdep files
This patch mechanically replaces convert_typed_floating with the equivalent target_float_convert throughout tdep files, to prepare for the removal of doublest.{c,h}. No functional change intended. gdb/ChangeLog: 2017-11-06 Ulrich Weigand <uweigand@de.ibm.com> * i386-tdep.c: Include "target-float.h". Do not include "doublest.h".
