9 daysnon-gcc: Remove trailing whitespaceJakub Jelinek4-8/+8
I've tried to build stage3 with -Wleading-whitespace=blanks -Wtrailing-whitespace=blank -Wno-error=leading-whitespace=blanks -Wno-error=trailing-whitespace=blank added to STRICT_WARN and that expectably resulted in about 2744 unique trailing whitespace warnings and 124837 leading whitespace warnings when excluding *.md files (which obviously is in big part a generator issue). Others from that are generator related, I think those need to be solved later. The following patch just fixes up the easy case (trailing whitespace), which could be easily automated: for i in `find . -name \*.h -o -name \*.cc -o -name \*.c | xargs grep -l '[ ]$' | grep -v testsuite/`; do sed -i -e 's/[ ]*$//' $i; done I've excluded files which I knew are obviously generated or go FE. Is there anything else we'd want to avoid the changes? Due to patch size, I've split it between gcc/ part and rest (include/, libiberty/, libgcc/, libcpp/, libstdc++-v3/; this part). 2024-10-24 Jakub Jelinek <jakub@redhat.com> include/ * dyn-string.h:

2023-01-13Fix support for atomic loads and stores on hppa.John David Anglin6-17/+400
This change updates the atomic libcall support to fix the following issues: 1) A internal compiler error with -fno-sync-libcalls. 2) When sync libcalls are disabled, we don't generate libcalls for libatomic. 3) There is no sync libcall support for targets other than linux. As a result, non-atomic stores are silently emitted for types smaller or equal to the word size. There are now a few atomic libcalls in the libgcc code, so we need sync support on all targets. 2023-01-13 John David Anglin <danglin@gcc.gnu.org> gcc/ChangeLog: * config/pa/pa-linux.h (TARGET_SYNC_LIBCALL): Delete define. * config/pa/pa.cc (pa_init_libfuncs): Use MAX_SYNC_LIBFUNC_SIZE define. * config/pa/pa.h (TARGET_SYNC_LIBCALLS): Use flag_sync_libcalls.

2022-10-06libgcc: Decrease size of _Unwind_FrameState and even more size of cleared ↵Jakub Jelinek2-11/+11
area in uw_frame_state_for The following patch implements something that has Florian found as low hanging fruit in our unwinder and has been discussed in the https://gcc.gnu.org/wiki/cauldron2022#cauldron2022talks.inprocess_unwinding_bof talk. _Unwind_FrameState type seems to be (unlike the pre-GCC 3 frame_state which has been part of ABI) private to unwind-dw2.c + unwind.inc it includes, it is always defined on the stack of some entrypoints, initialized by static uw_frame_state_for and the address of it is also passed to other static functions or the static inlines handling machine dependent unwinding, but it isn't fortunately passed to any callbacks or public functions, so I think we can safely change it any time we want. Florian mentioned that the structure is large even on x86_64, 384 bytes there, starts with 328 bytes long element with frame_state_reg_info type which then starts with an array with __LIBGCC_DWARF_FRAME_REGISTERS__ + 1 elements, each of them is 16 bytes long, on x86_64 __LIBGCC_DWARF_FRAME_REGISTERS__ is just 17 but even that is big, on say riscv __LIBGCC_DWARF_FRAME_REGISTERS__ is I think 128, on powerpc 111, on sh 153 etc. And, we memset to zero the whole fs variable with the _Unwind_FrameState type at the start of the unwinding. The reason why each element is 16 byte (on 64-bit arches) is that it contains some pointer or pointer sized integer and then an enum (with just 7 different enumerators) + padding. The following patch decreases it by moving the enum into a separate array and using just one byte for each register in that second array. We could compress it even more, say 4 bits per register, but I don't want to uglify the code for it too much and make the accesses slower. Furthermore, the clearing of the object can clear only thos how array and members after it, because REG_UNSAVED enumerator (0) doesn't actually need any pointer or pointer sized integer, it is just the other kinds that need to have there something. By doing this, on x86_64 the above numbers change to _Unwind_FrameState type being now 264 bytes long, frame_state_reg_info 208 bytes and we don't clear the first 144 bytes of the object, so the memset is 120 bytes, so ~ 31% of the old clearing size. On riscv 64-bit assuming it has same structure layout rules for the few types used there that would be ~ 2160 bytes of _Unwind_FrameState type before and ~ 1264 bytes after, with the memset previously ~ 2160 bytes and after ~ 232 bytes after. We've also talked about possibly adding a number of initially initialized regs and initializing the rest lazily, but at least for x86_64 with 18 elements in the array that doesn't seem to be worth it anymore, especially because return address column is 16 there and that is usually the first thing to be touched. It might theory help with lots of registers if they are usually untouched, but would uglify and complicate any stores to how by having to check there for the not initialized yet cases and lazy initialization, and similarly for all reads of how to do there if below last initialized one, use how, otherwise imply REG_UNSAVED. The disadvantage of the patch is that touching reg[x].loc and how[x] now means 2 cachelines rather than one as before, and I admit beyond bootstrap/regtest I haven't benchmarked it in any way. 2022-10-06 Jakub Jelinek <jakub@redhat.com> * unwind-dw2.h (REG_UNSAVED, REG_SAVED_OFFSET, REG_SAVED_REG, REG_SAVED_EXP, REG_SAVED_VAL_OFFSET, REG_SAVED_VAL_EXP, REG_UNDEFINED): New anonymous enum, moved from inside of struct frame_state_reg_info.

This change implements TI mode on PA64. Various new patterns are added to pa.md. The libgcc build needed modification to build both DI and TI routines. We also need various softfp routines to convert to and from TImode. I added full softfp for the -msoft-float option. At the moment, this doesn't completely eliminate all use of the floating-point co-processor. For this, libgcc needs to be built with -msoft-mult.

There is a builtin type mismatch in linux-atomic.c using the type long long unsigned int for 64-bit atomic operations on hppa64-linux. 2021-10-27 John David Anglin <danglin@gcc.gnu.org> libgcc/ChangeLog: * config.host (hppa*64*-*-linux*): Don't add pa/t-linux to tmake_file. * config/pa/linux-atomic.c: Define u8, u16 and u64 types. Use them in FETCH_AND_OP_2, OP_AND_FETCH_2, COMPARE_AND_SWAP_2, SYNC_LOCK_TEST_AND_SET_2 and SYNC_LOCK_RELEASE_1 macros. * config/pa/t-linux64 (LIB1ASMSRC): New define. (LIB1ASMFUNCS): Revise.

2021-08-31libgcc: Add missing runtime exception noticesRichard Sandiford1-2/+7
Quoting from https://gcc.gnu.org/pipermail/gcc/2021-July/236716.html: -------------------------------------------------------------------- It was pointed out to me off-list that config/aarch64/value-unwind.h is missing the runtime exception. It looks like a few other files are too; a fuller list is: libgcc/config/aarch64/value-unwind.h libgcc/config/frv/frv-abi.h libgcc/config/i386/value-unwind.h libgcc/config/pa/pa64-hpux-lib.h Certainly for the aarch64 file this was simply a mistake; it seems to have been copied from the i386 version, both of which reference the runtime exception but don't actually include it. -------------------------------------------------------------------- Similarly, frv-abi.h referenced the exception but didn't include it. pa64-hpux-lib.h was missing any reference to the exception. The decision was that this was simply a mistake [https://gcc.gnu.org/pipermail/gcc/2021-July/236717.html]: -------------------------------------------------------------------- […] It generally is considered a textual omission. The runtime library components of GCC are intended to be licensed under the runtime exception, which was granted and approved at the time of introduction. -------------------------------------------------------------------- and that we should simply change all of the files above [https://gcc.gnu.org/pipermail/gcc/2021-July/236719.html]: -------------------------------------------------------------------- Please correct the text in the files. The files in libgcc used in the GCC runtime are intended to be licensed with the runtime exception and GCC previously was granted approval for that licensing and purpose. […] The runtime exception explicitly was intended for this purpose and usage at the time that GCC received approval to apply the exception. -------------------------------------------------------------------- libgcc/ * config/aarch64/value-unwind.h: Add missing runtime exception paragraph. * config/frv/frv-abi.h: Likewise. * config/i386/value-unwind.h: Likewise. * config/pa/pa64-hpux-lib.h: Likewise.

2017-09-26Enable no-exec stacks for more targets using the Linux kernel.Joseph Myers1-0/+6
Building glibc for many different configurations and running the compilation parts of the testsuite runs into failures of the elf/check-execstack test for hppa and microblaze. Those configurations default to executable stacks in the Linux kernel because of VM_DATA_DEFAULT_FLAGS definitions including VM_EXEC (VM_DATA_DEFAULT_FLAGS being the default definition of VM_STACK_DEFAULT_FLAGS). This fails because those configurations are not generating .note.GNU-stack sections to indicate that programs do not need an executable stack. This patch fixes GCC to generate those sections on those architectures (when configured for a target using the Linux kernel), as it does on other architectures, together with adding that section to libgcc .S sources, with the same code as used on other architectures (or a variant using "#ifdef __linux__" instead of the usual "#if defined(__ELF__) && defined(__linux__)" for microblaze, as that configuration doesn't use elfos.h and so doesn't define __ELF__). This suffices to eliminate that glibc test failure. (For hppa, the compilation parts of the glibc testsuite still fail because of the separate elf/check-textrel failure.) gcc: * config/microblaze/linux.h (TARGET_ASM_FILE_END): Likewise. * config/pa/pa.h (NEED_INDICATE_EXEC_STACK): Likewise. * config/pa/pa-linux.h (NEED_INDICATE_EXEC_STACK): Likewise. * config/pa/pa.c (pa_hpux_file_end): Rename to pa_file_end.

2017-06-28Use ucontext_t not struct ucontext in linux-unwind.h files.Joseph Myers1-1/+1
Current glibc no longer gives the ucontext_t type the tag struct ucontext, to conform with POSIX namespace rules. This requires various linux-unwind.h files in libgcc, that were previously using struct ucontext, to be fixed to use ucontext_t instead. This is similar to the removal of the struct siginfo tag from siginfo_t some years ago. This patch changes those files to use ucontext_t instead. As the standard name that should be unconditionally safe, so this is not restricted to architectures supported by glibc, or conditioned on the glibc version. Tested compilation together with current glibc with glibc's build-many-glibcs.py. * config/aarch64/linux-unwind.h (aarch64_fallback_frame_state), config/alpha/linux-unwind.h (alpha_fallback_frame_state), config/bfin/linux-unwind.h (bfin_fallback_frame_state), config/i386/linux-unwind.h (x86_64_fallback_frame_state, x86_fallback_frame_state), config/m68k/linux-unwind.h (struct uw_ucontext), config/nios2/linux-unwind.h (struct nios2_ucontext), config/pa/linux-unwind.h (pa32_fallback_frame_state), config/riscv/linux-unwind.h (riscv_fallback_frame_state), config/sh/linux-unwind.h (sh_fallback_frame_state), config/tilepro/linux-unwind.h (tile_fallback_frame_state), config/xtensa/linux-unwind.h (xtensa_fallback_frame_state): Use ucontext_t instead of struct ucontext.
