Lu <hjl.to...@gmail.com> Date: Mon Oct 5 05:23:29 2020 -0700 x86: Clear modrm if not needed The MODRM byte can be checked to display the instruction name only if the MODRM byte needed. Clear modrm if the MODRM byte isn't needed so that modrm field checks in putop like, modrm.mod == N with N != 0, can be done without checking need_modrm. gas/ PR binutils/26705 * testsuite/gas/i386/x86-64-suffix.s: Add "mov %rsp,%rbp" before sysretq. * testsuite/gas/i386/x86-64-suffix-intel.d: Updated. * testsuite/gas/i386/x86-64-suffix.d: Likewise. opcodes/ PR binutils/26705 * i386-dis.c (print_insn): Clear modrm if not needed. (putop): Check need_modrm for modrm.mod != 3. Don't check need_modrm for modrm.mod == 3. -- You are receiving this mail because: You are on the CC list for the bug.
