File glibc-power6x.patch of Package glibc
2006-11-28 Jakub Jelinek <jakub@redhat.com> * elf/dl-support.c: Include dl-procinfo.h. * sysdeps/powerpc/dl-procinfo.h (PPC_PLATFORM_POWER4, PPC_PLATFORM_PPC970, PPC_PLATFORM_POWER5, PPC_PLATFORM_POWER5_PLUS, PPC_PLATFORM_POWER6, PPC_PLATFORM_CELL_BE, PPC_PLATFORM_POWER6X): Define. (_dl_string_platform): Use PPC_PLATFORM_* macros instead of hardcoded constants. * sysdeps/powerpc/dl-procinfo.c (_dl_powerpc_platform): Use PPC_PLATFORM_* macros for array designators. 2006-11-11 Steven Munroe <sjmunroe@us.ibm.com> * sysdeps/powerpc/dl-procinfo.c (_dl_powerpc_cap_flags): Add 3 new cap names to the beginning. (_dl_powerpc_platforms): Add "power6x". * sysdeps/powerpc/dl-procinfo.h (_DL_HWCAP_FIRST): Decrease. (HWCAP_IMPORTANT): Add PPC_FEATURE_HAS_DFP. (_DL_PLATFORMS_COUNT): Increase. (_dl_string_platform): Handle power6x case. * sysdeps/powerpc/sysdep.h (PPC_FEATURE_PA6T, PPC_FEATURE_HAS_DFP, PPC_FEATURE_POWER6_EXT): Define. (PPC_FEATURE_POWER5, PPC_FEATURE_POWER5_PLUS): Correct Comment. 2006-11-03 Steven Munroe <sjmunroe@us.ibm.com> * sysdeps/powerpc/dl-procinfo.c (_dl_powerpc_cap_flags): Add arch_2_05, ic_snoop, smt, and booke. [!PROCINFO_DECL](_dl_powerpc_platforms): Add "power4", "ppc970", "power5", "power5+", "power6", and "ppc-cell-be". * sysdeps/powerpc/dl-procinfo.h (HWCAP_IMPORTANT): Defined to be only PPC_FEATURE_HAS_ALTIVEC. Library selection based on AT_PLATFORM with altivec modifier. (_dl_string_platform): Search _dl_powerpc_platforms for match. --- elf/dl-support.c | 1 sysdeps/powerpc/dl-procinfo.c | 30 +++++++++++- sysdeps/powerpc/dl-procinfo.h | 97 +++++++++++++++++++++++++++++++++++------- sysdeps/powerpc/sysdep.h | 21 ++++++--- 4 files changed, 125 insertions(+), 24 deletions(-) Index: glibc-2.4/elf/dl-support.c =================================================================== --- glibc-2.4.orig/elf/dl-support.c +++ glibc-2.4/elf/dl-support.c @@ -29,6 +29,7 @@ #include <bits/libc-lock.h> #include <dl-cache.h> #include <dl-librecon.h> +#include <dl-procinfo.h> #include <unsecvars.h> #include <hp-timing.h> Index: glibc-2.4/sysdeps/powerpc/dl-procinfo.c =================================================================== --- glibc-2.4.orig/sysdeps/powerpc/dl-procinfo.c +++ glibc-2.4/sysdeps/powerpc/dl-procinfo.c @@ -1,5 +1,5 @@ /* Data for processor capability information.
