define PRINT_BIT_FIELD(Variable, FieldName) \ Print (L"%5a%42a: %x\n", #Variable, #FieldName, \ ##Variable.Bits.##FieldName);
The above definition in UefiCpuPkg/Application/Cpuid/Cpuid.c will cause GCC build error. Fix it with: define PRINT_BIT_FIELD(Variable, FieldName) \ Print (L"%5a%42a: %x\n", #Variable, #FieldName, \ Variable.Bits.FieldName); The '.' has its origin meaning as a member operator in the define statement. Thus, the token-pasting operator '##' is not necessary here.
