powerpc: Add hwcap/hwcap2/platform data to TCB. This patch adds a new feature for powerpc. In order to get faster access to the HWCAP/HWCAP2 bits and platform number (i.e. for implementing __builtin_cpu_is () / __builtin_cpu_supports () in GCC) without the overhead of reading from the auxiliary vector, we now reserve space for them in the TCB. This is an ABI change for GLIBC 2.23. A new versioned symbol '__parse_hwcap_and_convert_at_platform' is available to get the data from the auxiliary vector and parse it, and store it for later use in the TLS initialization code. This function is called very early (in _dl_sysdep_start () via DL_PLATFORM_INFO for the dynamic linking case, and in __libc_start_main () for the static linking case) to make sure the data is available at the time of TLS initialization. * sysdeps/powerpc/Makefile (sysdep-dl-routines): Add hwcapinfo.

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. (DT_PPC_NUM): Increment. * elf/dynamic-link.h (HAVE_STATIC_TLS): Define.

powerpc: Add hwcap/hwcap2/platform data to TCB. This patch adds a new feature for powerpc. In order to get faster access to the HWCAP/HWCAP2 bits and platform number (i.e. for implementing __builtin_cpu_is () / __builtin_cpu_supports () in GCC) without the overhead of reading from the auxiliary vector, we now reserve space for them in the TCB. This is an ABI change for GLIBC 2.23. A new versioned symbol '__parse_hwcap_and_convert_at_platform' is available to get the data from the auxiliary vector and parse it, and store it for later use in the TLS initialization code. This function is called very early (in _dl_sysdep_start () via DL_PLATFORM_INFO for the dynamic linking case, and in __libc_start_main () for the static linking case) to make sure the data is available at the time of TLS initialization. * sysdeps/powerpc/Makefile (sysdep-dl-routines): Add hwcapinfo. (sysdep_routines): Likewise. (sysdep-rtld-routines): Likewise. [$(subdir) = nptl](tests): Add test-get_hwcap and test-get_hwcap-static [$(subdir) = nptl](tests-static): test-get_hwcap-static * sysdeps/powerpc/Versions: Added new __parse_hwcap_and_convert_at_platform symbol to GLIBC-2.23. * sysdeps/powerpc/hwcapinfo.c: New file. (__tcb_parse_hwcap_and_convert_at_platform): New function to initialize and parse hwcap, hwcap2 and platform number information. * sysdeps/powerpc/hwcapinfo.h: New file. Creates global variables to store HWCAP+HWCAP2 and platform number. * sysdeps/powerpc/nptl/tcb-offsets.sym: Added new offsets for HWCAP+HWCAP2 and platform number in the TCB. * sysdeps/powerpc/nptl/tls.h: New functionality. Stores the HWCAP, HWCAP2 and platform number in the TCB. (dtv): Added new fields for HWCAP+HWCAP2 and platform number. (TLS_INIT_TP): Included calls to add the hwcap and at_platform values in the TCB in TP initialization. (TLS_DEFINE_INIT_TP): Likewise. (THREAD_GET_HWCAP): New macro. (THREAD_SET_HWCAP): Likewise. (THREAD_GET_AT_PLATFORM): Likewise. (THREAD_SET_AT_PLATFORM): Likewise. * sysdeps/powerpc/powerpc32/dl-machine.h: (dl_platform_init): New function that calls __parse_hwcap_and_convert_at_platform for the dymanic linking case for powerpc32. * sysdeps/powerpc/powerpc64/dl-machine.h: Likewise, for powerpc64. * sysdeps/powerpc/test-get_hwcap-static.c: New file. Testcase for this functionality, static linking case. * sysdeps/powerpc/test-get_hwcap.c: New file. Likewise, dynamic linking case. * sysdeps/unix/sysv/linux/powerpc/libc-start.c: Added call to __parse_hwcap_and_convert_at_platform for the static linking case. * sysdeps/unix/sysv/linux/powerpc/powerpc32/ld.abilist: Included the new __parse_hwcap_and_convert_at_platform symbol in the ABI list for GLIBC 2.23. * sysdeps/unix/sysv/linux/powerpc/powerpc64/ld-le.abilist: Likewise. * sysdeps/unix/sysv/linux/powerpc/powerpc64/ld.abilist: Likewise.
