I'm not sure what are these bits defined according to. From PV of HW, I think this shouldn't be added. This bit is set by hypervisor rather than CPU like others. And I found this bit is still 0 in my VM. > bit_IA57: Appears to be defined in June 2021 Intel SDM at Vol. 2A 3-219 (PDF > page 794). Oh, I missed that. Thanks. GCC has the same (but fewer) definitions, https://github.com/gcc-mirror/gcc/blob/master/gcc/config/i386/cpuid.h +@hjl.tools to have a look. ================ Comment at: clang/lib/Headers/cpuid.h:159 +#define bit_RDTM 0x00001000 +#define bit_DEPRFPUCSDS 0x00002000 +#define bit_MPX 0x00004000 ---------------- `DEPR_FPU_CSDS` ?
