Lu <[email protected]> Date: Thu Dec 12 12:25:48 2019 -0800 i386: Also check R12-R15 registers when optimizing testq to testb Similar to SP, BP, SI and DI registers, R12-R15 registers must use REX prefix for the low byte register when optimizing test $imm7, %r64/%r32/%r16 -> test $imm7, %r8 PR gas/25274 * config/tc-i386.c (optimize_encoding): Also check R12-R15 registers for "test $imm7, %r64/%r32/%r16 -> test $imm7, %r8" optimization. * testsuite/gas/i386/x86-64-optimize-3.s: Add tests for test with r12. * testsuite/gas/i386/x86-64-optimize-3.d: Updated. * testsuite/gas/i386/x86-64-optimize-3b.d: Likewise. -- You are receiving this mail because: You are on the CC list for the bug.
