--- Comment #7 from Jason Vas Dias <jason.vas.dias at gmail dot com> --- Aha! Am I right in thinking 'f3.0f.1e.fa' (hex byte string) specifies x86_64 instruction 'RDSSPD/RDSSPQ' ? I think so ! : >From Intel Software Developer's Manual (SDM), Book 2, Instructions, Chapter 3, Instruction Set Reference, page Vol-2B,4-553 (pp.1735) : " RDSSPD/RDSSPQ—Read Shadow Stack Pointer Opcode/ Op/ 64/32 CPUID F3 0F 1E /1 (mod=11) R V/V CET_SS Copy low 32 bits of shadow stack pointer (SSP) to r32. RDSSPD r32 F3 REX.W 0F 1E /1 (mod=11) R V/N.E. CET_SS Copies shadow stack pointer (SSP) to r64. RDSSPQ r64 " So, then maybe the code should take this as an indication that the job has been done OK and so NOT to raise an error here ? -- You are receiving this mail because: You are on the CC list for the bug.
