Hi, All: I have a question about NOOPT and PcdOptimizeCompilerEnable. If Target = NOOPT, then will disable all optimizations. And PcdOptimizeCompilerEnable has the same function. So, What's the relationship between PcdOptimizeCompilerEnable and NOOPT? Thanks Best wishes, ????? ?????????????????????????????????????????????????????
