From d2ba6f41e2f8cbc8dffee8bddaebbbd6f3a3b9ab Mon Sep 17 00:00:00 2001 From: Hao Wu Date: Fri, 26 Feb 2016 16:43:02 +0800 Subject: [PATCH] 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.
