* powerpc: Re-work the Implies structureLuis Machado2010-06-3048-58/+44
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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)
* Improve 64bit memcpy/memmove for Atom, Core 2 and Core i7H.J. Lu2010-06-3018-8/+6640
| | | | | | | This patch includes optimized 64bit memcpy/memmove for Atom, Core 2 and Core i7. It improves memcpy by up to 3X on Atom, up to 4X on Core 2 and up to 1X on Core i7. It also improves memmove by up to 3X on Atom, up to 4X on Core 2 and up to 2X on Core i7.

| | | | | | The getdents64 syscall adds on 32-but platforms padding which isn't needed and not included in the userlevel data structure definition. We have to avoid copying those padding bytes in the readdir64_r function.

* Define miss_F_GETOWN_EX only if needed.Ulrich Drepper2010-03-271-11/+11
| | | | | | | When doing i686-unknown-linux-gnu build configured with --enable-kernel=2.6.24, there are several warnings like this: ../sysdeps/unix/sysv/linux/i386/fcntl.c:36:12: warning: ‘miss_F_GETOWN_EX’ defined but not used
* Mark _dl_random attribute_relro in the header file.Richard Henderson2010-03-261-1/+1
| | | | | | | | It's already so marked in dl-sysdep.c. Failure to so mark in the header file leads the compiler to believe that the variable should be addressable via the .sdata section. Signed-off-by: Richard Henderson <rth@twiddle.net>
* Don't take the address of a void object.Richard Henderson2010-03-261-4/+4
| | | | | | | | GCC 4.5 warns about "extern void _end; &end;". Use char[] instead, as that also doesn't fall foul of a target's .sdata optimizations. Signed-off-by: Richard Henderson <rth@twiddle.net>
* Fix one case of last checkin.Ulrich Drepper2010-03-261-0/+1
| | | | If the v4 lookup failed but v6 succeeded we treat this as a success.
* Don't abort immediately on successful lookup in getaddrinfo.Ulrich Drepper2010-03-261-10/+10
| | | | | | | When not using gethostbyname4 methods we immediately aborted the loop over the nss modules on the first successful lookup. While this is almost always what is wanted the nsswitch.conf file allows to select something different.
