elf: Remove HWCAP_IMPORTANT

2024-06-18T08:45:36Z

Remove the definitions of HWCAP_IMPORTANT after removal of LD_HWCAP_MASK / tunable glibc.cpu.hwcap_mask. There HWCAP_IMPORTANT was used as default value. Reviewed-by: Adhemerval Zanella

elf: Remove _DL_PLATFORMS_COUNT

2024-06-18T08:45:36Z

Remove the definitions of _DL_PLATFORMS_COUNT as those are not used anymore after removal in elf/dl-cache.c:search_cache(). Note: On x86, we can also get rid of the definitions HWCAP_PLATFORMS_START and HWCAP_PLATFORMS_COUNT. Reviewed-by: Adhemerval Zanella

elf: Remove _DL_HWCAP_PLATFORM

2024-06-18T08:45:36Z

Remove the definitions of _DL_HWCAP_PLATFORM as those are not used anymore after removal in elf/dl-cache.c:search_cache(). Reviewed-by: Adhemerval Zanella

elf: Remove platform strings in dl-procinfo.c

2024-06-18T08:45:36Z

Remove the platform strings in dl-procinfo.c where also the implementation of _dl_string_platform() was removed. Reviewed-by: Adhemerval Zanella

elf: Remove _dl_string_platform

2024-06-18T08:45:36Z

Despite of powerpc where the returned integer is stored in tcb, and the diagnostics output, there is no user anymore. Thus this patch removes the diagnostics output and _dl_string_platform for all other platforms. Reviewed-by: Adhemerval Zanella

Implement C23 logp1

2024-06-17T13:47:09Z

C23 adds various function families originally defined in TS 18661-4. Add the logp1 functions (aliases for log1p functions - the name is intended to be more consistent with the new log2p1 and log10p1, where clearly it would have been very confusing to name those functions log21p and log101p). As aliases rather than new functions, the content of this patch is somewhat different from those actually adding new functions. Tests are shared with log1p, so this patch *does* mechanically update all affected libm-test-ulps files to expect the same errors for both functions. The vector versions of log1p on aarch64 and x86_64 are *not* updated to have logp1 aliases (and thus there are no corresponding header, tests, abilist or ulps changes for vector functions either). It would be reasonable for such vector aliases and corresponding changes to other files to be made separately. For now, the log1p tests instead avoid testing logp1 in the vector case (a Makefile change is needed to avoid problems with grep, used in generating the .c files for vector function tests, matching more than one ALL_RM_TEST line in a file testing multiple functions with the same inputs, when it assumes that the .inc file only has a single such line). Tested for x86_64 and x86, and with build-many-glibcs.py.

It allows to remove a lot of arch-specific implementations. Checked on x86_64, aarch64, powerpc64. Reviewed-by: Carlos O'Donell

Refer to C23 in place of C2X in glibc

2024-02-01T11:02:01Z

WG14 decided to use the name C23 as the informal name of the next revision of the C standard (notwithstanding the publication date in 2024). Update references to C2X in glibc to use the C23 name. This is intended to update everything *except* where it involves renaming files (the changes involving renaming tests are intended to be done separately). In the case of the _ISOC2X_SOURCE feature test macro - the only user-visible interface involved - support for that macro is kept for backwards compatibility, while adding _ISOC23_SOURCE. Tested for x86_64.
