This changes the PowerPC64 --plt-align option to perform the usual alignment of code as suggested by its name, as well as the previous behaviour of padding so as to reduce boundary crossing. The old behaviour is had by using a negative parameter. The default is also changed to align plt stub code by default to 32 byte boundaries, the point being to get better bctr branch prediction on power8 and power9 hardware. bfd/ * elf64-ppp.c (plt_stub_pad): Handle positive and negative plt_stub_align. ld/ * ld.texinfo (--plt-align): Describe new behaviour of option. * emultempl/ppc64elf.em (params): Default plt_stub_align to 5. * testsuite/ld-powerpc/powerpc.exp: Pass --no-plt-align for selected tests. * testsuite/ld-powerpc/relbrlt.d: Pass --no-plt-align. * testsuite/ld-powerpc/elfv2so.d: Adjust expected output. (cherry picked from commit 2420fff6) (and commit bab55c05 for part of elfv2so.d change)

Since the NOTRACK prefix is no longer required to be the last prefix before the REX prefix, restriction on the NOTRACK prefix position is removed from assembler as well as disassembler. Assembler encodes the NOTRACK prefix the same way as the DS segment register, which places it before other prefixes. Disassembler displays prefixes in the order they appear. gas/ * config/tc-i386.c (NOTRACK_PREFIX): Removed. (REX_PREFIX): Updated. (MAX_PREFIXES): Likewise.
