2010-06-30powerpc: Re-work the Implies structureLuis Machado
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)

2009-11-06Fix R_PPC64_{JMP_IREL,IRELATIVE} handling in dl-conflict.c.Jakub Jelinek
I've just committed STT_GNU_IFUNC ppc/ppc64 support into prelink, and this patch is needed on the glibc side. Without it ld.so segfaults, as in dl-conflict.c sym_map is always NULL. While dl-machine.h could use RESOLVE_CONFLICT_FIND_MAP macro to compute it, it doesn't make sense, because with prelink we know it is already properly relocated (all relative relocations are applied by prelink).
