There is no performance advantage to use multi-byte nop instructions greater than 10 bytes. This patch limits multi-byte nop instructions to 10 bytes. Since there is only one way to encode multi-byte nop instructions now, it also removed redundant nop tests. gas/ * config/tc-i386.c (i386_align_code): Limit multi-byte nop instructions to 10 bytes. gas/testsuite/ * gas/i386/i386.exp: Don't run nops-1-bdver1, nops-1-bdver2, nops-1-bdver3, nops-1-bdver4, nops-1-znver1, nops-1-btver1 nops-1-btver2, x86-64-nops-1-nocona, x86-64-nops-1-bdver1, x86-64-nops-1-bdver2, x86-64-nops-1-bdver3, x86-64-nops-1-bdver4, x86-64-nops-1-znver1, x86-64-nops-1-btver1 nor x86-64-nops-1-btver2. * gas/i386/nops-1-core2.d: Updated. * gas/i386/nops-1-k8.d: Likewise. * gas/i386/nops-4a-i686.d: Likewise. * gas/i386/nops-5-i686.d: Likewise. * gas/i386/nops-5.d: Likewise. * gas/i386/nops-6.d: Likewise. * gas/i386/x86-64-nops-1-core2.d: Likewise. * gas/i386/x86-64-nops-1-g64.d: Likewise. * gas/i386/x86-64-nops-1-k8.d: Likewise. * gas/i386/x86-64-nops-1.d: Likewise. * gas/i386/x86-64-nops-2.d: Likewise. * gas/i386/x86-64-nops-3.d: Likewise. * gas/i386/x86-64-nops-4-core2.d: Likewise. * gas/i386/x86-64-nops-4-k8.d: Likewise. * gas/i386/x86-64-nops-4.d: Likewise. * gas/i386/x86-64-nops-5-k8.d: Likewise. * gas/i386/x86-64-nops-5.d: Likewise. * gas/i386/ilp32/x86-64-nops-1-core2.d: Likewise. * gas/i386/ilp32/x86-64-nops-1-k8.d: Likewise. * gas/i386/ilp32/x86-64-nops-1.d: Likewise. * gas/i386/ilp32/x86-64-nops-2.d: Likewise. * gas/i386/ilp32/x86-64-nops-3.d: Likewise. * gas/i386/ilp32/x86-64-nops-4-core2.d: Likewise. * gas/i386/ilp32/x86-64-nops-4-k8.d: Likewise. * gas/i386/ilp32/x86-64-nops-4.d: Likewise. * gas/i386/ilp32/x86-64-nops-5-k8.d: Likewise. * gas/i386/ilp32/x86-64-nops-5.d: Likewise. * gas/i386/nops-1-bdver1.d: Removed. * gas/i386/nops-1-bdver2.d: Likewise. * gas/i386/nops-1-bdver3.d: Likewise. * gas/i386/nops-1-bdver4.d: Likewise. * gas/i386/nops-1-btver1.d: Likewise. * gas/i386/nops-1-btver2.d: Likewise. * gas/i386/nops-1-znver1.d: Likewise. * gas/i386/x86-64-nops-1-bdver1.d: Likewise. * gas/i386/x86-64-nops-1-bdver2.d: Likewise. * gas/i386/x86-64-nops-1-bdver3.d: Likewise. * gas/i386/x86-64-nops-1-bdver4.d: Likewise. * gas/i386/x86-64-nops-1-btver1.d: Likewise. * gas/i386/x86-64-nops-1-btver2.d: Likewise. * gas/i386/x86-64-nops-1-nocona.d: Likewise. * gas/i386/x86-64-nops-1-znver1.d: Likewise. * gas/i386/ilp32/x86-64-nops-1-nocona.d: Likewise. |
