If it's not too late in the release cycle, I'd appreciate if this patch enabling optimal code alignment up to 32-byte boundaries, used by GCC when tuning for AMD Barcelona, were applied. It also does away with the special NOP sequences for AMD Opteron in 64-bit code. 2007-06-29 Evandro Menezes <evandro.menezes@amd.com> * config/tc-i386.c (handle_align_code, i386_align_code): new function to help alignment > 15 bytes, enable alignment up to 31 bytes, always use variable-length NOP for K8 too. * config/tc-i386.h (MAX_MEM_FOR_RS_ALIGN_CODE): change limit to 31 bytes. * testsuite/gas/i386/i386.exp: replace NOP test-case and remove K8-specific NOP test-case. * testsuite/gas/i386/nops-3-i686.d: new NOP test-case. * testsuite/gas/i386/x86-64-nops-1-k8.d: removed.
