Yes. This is the expect behavior. Compiler optimization is disabled, then Od option will be used for VS tool chain.

Hi, Liming:

Thanks for your explanation.

If setting PcdOptimizeCompilerEnable as disable, then will cause D9025 compiling warning.

Such as:

cl : Command line warning D9025 : overriding '/O1' with '/Od'

So, is it ok?

Thanks

NOOPT is build target. It includes the compiler option to disable optimization. If the platform supports NOOPT target, it can be built with -b NOOPT.

PcdOptimizeCompilerEnable is one feature PCD defined in edk2-platforms. It can be used to control the compiler option in [BuildOptions] section. It can also be used for DEBUG or RELEASE target.

Thanks

Liming

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,
