UefiCpuPkg/Cpuid: Fix GCC build error
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.
