* nptl: Remove exit-thread.hAdhemerval Zanella2021-06-043-66/+2
| | | | | No function change. The code is used only for Linux, besides being included in generic code.
* dlfcn: Rework static dlopen hooksFlorian Weimer2021-06-031-0/+3
| | | | | | | | | | | | | | Consolidate all hooks structures into a single one. There are no static dlopen ABI concerns because glibc 2.34 already comes with substantial ABI-incompatible changes in this area. (Static dlopen requires the exact same dynamic glibc version that was used for static linking.) The new approach uses a pointer to the hooks structure into _rtld_global_ro and initalizes it in __rtld_static_init. This avoids a back-and-forth with various callback functions.

* dlfcn: Cleanups after -ldl is no longer requiredFlorian Weimer2021-06-033-15/+5
| | | | | | | | | | | | This commit removes the ELF constructor and internal variables from dlfcn/dlfcn.c. The file now serves the same purpose as nptl/libpthread-compat.c, so it is renamed to dlfcn/libdl-compat.c. The use of libdl-shared-only-routines ensures that libdl.a is empty. This commit adjusts the test suite not to use $(libdl). The libdl.so symbolic link is no longer installed. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>

| | | | | | | | | | | | | | The symbol was moved using scripts/move-symbol-to-libc.py. There is a minor functionality enhancement: dlerror now sets errno if it was set as part of the exception. (This is the result of using %m in asprintf, to avoid the strerror PLT call.) The previous errno value upon function return was unpredictable. Documenting this as a feature is premature; we need to make sure that the error codes are meaningful when they are set by the dynamic loader.

* Add libc ABI extension kludge for baseline-violating libdl symbolsFlorian Weimer2021-06-024-0/+4
| | | | | | | | | | | | | | | | | | | Some targets have a GLIBC_2.0 baseline for libdl, while using GLIBC_2.2 for libc. This means that the generated libc.map file does not have any version nodes for GLIBC_2.0 or GLIBC_2.1. However, moving symbols from libdl into libc needs such version nodes. (Future symbol moves from librt will need this as well.) This kludge is only necessary for symbols predating GLIBC_2.2 because the affected targets use GLIBC_2.2 as the baseline for libc. Given the small number and fixed set of affected architectures, no generic mechanism is implemented, and instead the map file fragment is hard-coded in scripts/versions.mk. The compat_symbol macro already emits the appropriate version strings, so no adjustments are needed there. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>

* powerpc: Optimized memcmp for power10Lucas A. M. Magalhaes2021-05-315-1/+218
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch was based on the __memcmp_power8 and the recent __strlen_power10. Improvements from __memcmp_power8: 1. Don't need alignment code. On POWER10 lxvp and lxvl do not generate alignment interrupts, so they are safe for use on caching-inhibited memory. Notice that the comparison on the main loop will wait for both VSR to be ready. Therefore aligning one of the input address does not improve performance. In order to align both registers a vperm is necessary which add too much overhead. 2. Uses new POWER10 instructions This code uses lxvp to decrease contention on load by loading 32 bytes per instruction. The vextractbm is used to have a smaller tail code for calculating the return value. 3. Performance improvement This version has around 35% better performance on average. I saw no performance regressions for any length or alignment. Thanks Matheus for helping me out with some details.

SVE assembler code for memset is implemented as Vector Length Agnostic code so theoretically it can be run on any SOC which supports ARMv8-A SVE standard. We confirmed that all testcases have been passed by running 'make check' and 'make xcheck' not only on A64FX but also on ThunderX2.

| | | | | | | | | | | | | | | | | | | Use the __nptl_tls_static_size_for_stack inline function instead, and the GLRO (dl_tls_static_align) value directly. The computation of GLRO (dl_tls_static_align) in _dl_determine_tlsoffset ensures that the alignment is at least TLS_TCB_ALIGN, which at least STACK_ALIGN (see allocate_stack). Therefore, the additional rounding-up step is removed. ALso move the initialization of the default stack size from __pthread_initialize_minimal_internal to __pthread_early_init. This introduces an extra system call during single-threaded startup, but this simplifies the initialization sequence. No locking is needed around the writes to __default_pthread_attr because the process is single-threaded at this point. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>

| | | | | | | | | | | | | | | | | | | ISO C2X adds a timespec_getres function alongside the C11 timespec_get, with functionality similar to that of POSIX clock_getres (including allowing a NULL pointer to be passed to the function). Implement this function for glibc, similarly to the implementation of timespec_get. This includes a basic test like that of timespec_get, but no documentation in the manual, given that TIME_UTC and timespec_get aren't documented in the manual at all. The handling of 64-bit time follows that in timespec_get; people maintaining patch series for 64-bit time will need to update them accordingly (to export __timespec_getres64, redirect calls in time.h and run the test for _TIME_BITS=64). Tested for x86_64 and x86, and (previous version; only testcase differs) with build-many-glibcs.py.
* powerpc: Add optimized rawmemchr for POWER10Matheus Castanho2021-05-176-27/+188
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Reuse code for optimized strlen to implement a faster version of rawmemchr. This takes advantage of the same benefits provided by the strlen implementation, but needs some extra steps. __strlen_power10 code should be unchanged after this change. rawmemchr returns a pointer to the char found, while strlen returns only the length, so we have to take that into account when preparing the return value. To quickly check 64B, the loop on __strlen_power10 merges the whole block into 16B by using unsigned minimum vector operations (vminub) and checks if there are any \0 on the resulting vector. The same code is used by rawmemchr if the char c is 0. However, this approach does not work when c != 0. We first need to subtract each byte by c, so that the value we are looking for is converted to a 0, then taking the minimum and checking for nulls works again. The new code branches after it has compared ~256 bytes and chooses which of the two strategies above will be used in the main loop, based on the char c. This extra branch adds some overhead (~5%) for length ~256, but is quickly amortized by the faster loop for larger sizes. Compared to __rawmemchr_power9, this version is ~20% faster for length < 256. Because of the optimized main loop, the improvement becomes ~35% for c != 0 and ~50% for c = 0 for strings longer than 256. Reviewed-by: Lucas A. M.
