2010-06-30powerpc: Re-work the Implies structureLuis Machado11-12/+8
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)
