* Implement C23 logp1Joseph Myers2024-06-171-0/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | C23 adds various <math.h> 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.
* elf: Only process multiple tunable once (BZ 31686)Adhemerval Zanella2024-05-071-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | The 680c597e9c3 commit made loader reject ill-formatted strings by first tracking all set tunables and then applying them. However, it does not take into consideration if the same tunable is set multiple times, where parse_tunables_string appends the found tunable without checking if it was already in the list. It leads to a stack-based buffer overflow if the tunable is specified more than the total number of tunables. For instance: GLIBC_TUNABLES=glibc.malloc.check=2:... (repeat over the number of total support for different tunable). Instead, use the index of the tunable list to get the expected tunable entry. Since now the initial list is zero-initialized, the compiler might emit an extra memset and this requires some minor adjustment on some ports. Checked on x86_64-linux-gnu and aarch64-linux-gnu.

* Refer to C23 in place of C2X in glibcJoseph Myers2024-02-011-1/+1
| | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | The functions were previously written in C, but were not compiled with unwind information. The ENTRY/END macros includes .cfi_startproc and .cfi_endproc which adds unwind information. This caused the tests cleanup-8 and cleanup-10 in the GCC testsuite to fail. This patch adds a version of the ENTRY/END macros without the CFI instructions that can be used instead. sigaction registers a restorer address that is located two instructions before the stub function. This patch adds a two instruction padding to avoid that the unwinder accesses the unwind information from the function that the linker has placed right before it in memory. This fixes an issue with pthread_cancel that caused tst-mutex8-static (and other tests) to fail.

These symbols appear to be in libc only for compatibility, maybe one of the cases where they were accidentally exported from shared libc in glibc 2.0 before the introduction of symbol versioning and so programs started expecting shared libc to provide them. Thus, there is no need to have them in static libc. Add this set of libgcc functions to shared-only-routines so they are no longer provided in static libc. (No change is made regarding .mul - dotmul source file - since unlike the other symbols in this grouping, it doesn't actually appear to be a libgcc symbol, at least in current GCC.) Tested with build-many-glibcs.py for sparcv9-linux-gnu with GCC mainline.
