PowerPC64 ELFv2 ABI 6/6: Bump ld.so soname version number To avoid having a ELFv2 binary accidentally picking up an old ABI ld.so, this patch bumps the soname to ld64.so.2. In theory (or for testing purposes) this will also allow co-installing ld.so versions for both ABIs on the same system. Note that the kernel will already be able to load executables of both ABIs. However, there is currently no plan to use that theoretical possibility in a any supported distribution environment ... Note that in order to check which ABI to use, we need to invoke the compiler to check the _CALL_ELF macro; this is done in a new configure check in sysdeps/unix/sysv/linux/powerpc/powerpc64/configure.ac, replacing the hard-coded value of default-abi in the Makefile.

powerpc __tls_get_addr call optimization This patch is glibc support for a PowerPC TLS optimization, inspired by Alexandre Oliva's TLS optimization for other processors, http://www.lsd.ic.unicamp.br/~oliva/writeups/TLS/RFC-TLSDESC-x86.txt In essence, this optimization uses a zero module id in the tls_index GOT entry to indicate that a TLS variable is allocated space in the static TLS area. A special plt call linker stub for __tls_get_addr checks for such a tls_index and if found, returns the offset immediately. The linker communicates the fact that the special __tls_get_addr stub is used by setting a bit in the dynamic tag DT_PPC64_OPT/DT_PPC_OPT. glibc communicates to the linker that this optimization is available by the presence of __tls_get_addr_opt. tst-tlsmod2.so is built with -Wl,--no-tls-get-addr-optimize for tst-tls-dlinfo, which otherwise would fail since it tests that no static tls is allocated. The ld option --no-tls-get-addr-optimize has been available since binutils-2.20 so doesn't need a configure test. * NEWS: Advertise TLS optimization. * elf/elf.h (R_PPC_TLSGD, R_PPC_TLSLD, DT_PPC_OPT, PPC_OPT_TLS): Define.

powerpc: Fix static-linked version of __ppc_get_timebase_freq [BZ #24640] __ppc_get_timebase_freq() always return 0 when using static linked glibc. This is a minimal example.c to reproduce: /******************************/ #include <inttypes.h> #include <stdint.h> #include <stdio.h> #include <sys/platform/ppc.h> int main() { uint64_t freq = __ppc_get_timebase_freq(); printf("Time Base frequency = %"PRIu64" Hz\n", freq); if (freq == 0) return -1; return 0; } /******************************/ Compile command: gcc -static example.c This bug has been reproduced, fixed and tested on all powerpc platforms (ppc32, ppc64 and ppc64le). The underlying code of __ppc_get_timebase_freq uses __get_timebase_freq that has a different implementation for shared and static version of glibc. In the static version, there is an incorrect sense in the if check for the fd returned when opening /proc/cpuinfo. This solution is mostly a cherry-pick from: commit 4791e4f773d060c1a37b27aac5b03cdfa9327afc Author: Stan Shebs <stanshebs@google.com> Date: Fri May 17 12:25:19 2019 -0700 Subject: Fix sense of a test in the static-linking version of ppc get_clockfreq That is in branch glibc/google/grte/v5-2.27/master and was mentioned for inclusion on master here: https://www.sourceware.org/ml/libc-alpha/2019-05/msg00409.html Adapted from original fix for get_clockfreq. That code was moved to get_timebase_freq. Also added a static-build testcase for __ppc_get_timebase_freq since the underlying function has different implementations for shared and static build.

powerpc: add sysconf support for cache geometries There is currently no "cross-platform" (x86 and POWER) support for determining the cacheline size. This patch adds support to sysconf() to correctly report cacheline sizes based on the information in the auxilliary vector.

Support is added (on powerpc) for: _SC_LEVEL1_ICACHE_SIZE _SC_LEVEL1_ICACHE_ASSOC _SC_LEVEL1_ICACHE_LINESIZE _SC_LEVEL1_DCACHE_SIZE _SC_LEVEL1_DCACHE_ASSOC _SC_LEVEL1_DCACHE_LINESIZE _SC_LEVEL2_CACHE_SIZE _SC_LEVEL2_CACHE_ASSOC _SC_LEVEL2_CACHE_LINESIZE _SC_LEVEL3_CACHE_SIZE _SC_LEVEL3_CACHE_ASSOC _SC_LEVEL3_CACHE_LINESIZE * sysdeps/unix/sysv/linux/powerpc/sysconf.c: New file.

powerpc: Relocate stinfo->main start_addresses in sysdeps/powerpc/powerpc64/start.S is historical baggage that should disappear. Until someone does that, relocating stinfo->main by hand is one solution to the fact that the field may be unrelocated at the time it is accessed. This is similar to what is done for dynamic tags via the D_PTR macro. stinfo->init and stinfo->fini are zero in both powerpc64/start.S and powerpc32/start.S, so make it a little more obvious they are unused by passing NULLs to LIBC_START_MAIN. The makefile change is needed to pick up elf/dl-static-tls.h from dl-machine.h. Reviewed-by: Tulio Magno Quites Machado Filho <tuliom@linux.ibm.com>
