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: 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. Thus, using sysconf() is a cross-platform (x86 and POWER) solution for determining cacheline sizes. 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: Add the lock elision using HTM This patch adds support for lock elision using ISA 2.07 hardware transactional memory instructions for pthread_mutex primitives. Similar to s390 version, the for elision logic defined in 'force-elision.h' is only enabled if ENABLE_LOCK_ELISION is defined. Also, the lock elision code should be able to be built even with a compiler that does not provide HTM support with builtins. However I have noted the performance is sub-optimal due scheduling pressures.
