  third_party/crashpad/crashpad/snapshot/x86/cpuid_reader.cc(116,3): error: always_inline function '_fxsave' requires target feature 'fxsr', but would be inlined into function 'SupportsDAZ' that is compiled without support for 'fxsr'
    116 |   _fxsave(&fxsave);
        |   ^

  third_party/crashpad/crashpad/snapshot/win/system_snapshot_win.cc(438,3): error: always_inline function '_fxsave' requires target feature 'fxsr', but would be inlined into function 'CPUX86SupportsDAZ' that is compiled without support for 'fxsr'
