2010-07-13 powerpc: POWER7 optimizationsibm/2.8/masterLuis Machado
Add optimizations for classification functions (32-bit and 64-bit) and string functions (32-bit and 64-bit). powerpc: Re-work the Implies structure This patch tries to organize the implies files for ppc, since there are a number of processors and most of them are compatible with each other (backwards compatible). Having in mind that we start the search for processor-specific files in the sysdeps/unix/sysv/linux tree (sysdeps/unix/sysv/linux/powerpc/powerpc[32|64]/[processor]/fpu to be exact), we would like to grab any linux-specific code from that tree prior to going through the other tree (sysdeps/powerpc/...). For that, i removed the Implies files that were originally inside the fpu directories and placed then in the non-fpu directories (still inside the unix/sysv/linux tree). If no processor-specific/linux-specific files could be found, we "imply" the other tree's (sysdeps/powerpc/...) fpu directory for that specific processor AND also the non-fpu directory for that same tree. If, again, no processor-specific code is found, we read another Implies file that will point to the most compatible processor that we should grab code from, and so on, until we reach the power4 processor. So, in summary, the Implies files will live inside these directories now: * sysdeps/unix/sysv/linux/powerpc/powerpc[32|64]/[processor] * sysdeps/powerpc/powerpc[32|64]/[processor] Practical example of the order we will use to pick power6-specific code with the new structure. sysdeps/unix/sysv/linux/powerpc/powerpc[32|64]/power6/fpu -> sysdeps/unix/sysv/linux/powerpc/powerpc[32|64]/power6 -> sysdeps/powerpc/powerpc[32|64]/power6/fpu -> sysdeps/powerpc/powerpc[32|64]/power6 -> sysdeps/powerpc/powerpc[32|64]/power5+/fpu -> sysdeps/powerpc/powerpc[32|64]/power5+ -> sysdeps/powerpc/powerpc[32|64]/power5/fpu -> sysdeps/powerpc/powerpc[32|64]/power5 -> sysdeps/powerpc/powerpc[32|64]/power4/fpu -> sysdeps/powerpc/powerpc[32|64]/power4 (from here, it'll go to the generic path as usual)

* ChangeLog: Updated to reflect following patch. Selective Cherry Pick of Roland McGrath's head commit 7967983fd42380b090a63b53fe57a05e1d1c0b4f. The configure.in and Makefile parts are the same as Roland's patch but since this is a backport to a GLIBC 2.8 branch the individual configure files are different so those were regenerated locally by Ryan. Roland's ChangeLog is still relevant: 2009-09-15 Roland McGrath <roland@redhat.com> * aclocal.m4 (GLIBC_PROVIDES): Add _AS_ECHO_PREPARE. * nptl/sysdeps/pthread/configure: Regenerated. * nptl/sysdeps/x86_64/configure: Regenerated. * sysdeps/unix/sysv/linux/configure: Regenerated. * sysdeps/x86_64/elf/configure: Regenerated. * Makefile (autoconf-it): Set execute bit only on top-level configure. * configure.in: Let add-ons set $libc_add_on_config_subdirs to have the effect of AC_CONFIG_SUBDIRS relative to the add-on directory. * aclocal.m4 (GLIBC_PROVIDES): Add AC_CONFIG_SUBDIRS. * configure: Regenerated. This fix makes configure recurse into an add-on's standalone directories where the directories in libc_add_on_config_subdirs (relative path to the add-on) have their own pre-configured 'configure' and 'Makefile.in' that is maintained 'out-of-project'.
