--- Comment #7 from Ivo Raisr <iv...@ivosh.net> --- Weird, line 20564 pertains to decoding "pop" instruction. There is a test case in Valgrind regression test suite: none/tests/amd64/bmi.c which exercises bextr with the following operands: c4 e2 f0 f7 d6 bextr %rcx,%rsi,%rdx c4 e2 f0 f7 55 d0 bextr %rcx,-0x30(%rbp),%rdx Perhaps the problem we see here is that the first operand is an immediate instead of a register? Also there is similar bug 322586 where folks were reporting unrecognized bextr (0x8F 0xEA 0xF8 0x10 0xCA 0x3 0x1D). Perhaps you could try the patch attached there if it works for you? -- You are receiving this mail because: You are watching all bug changes.
