Thanks for looking into this. It is alwa= ys good to try and do things the same way on different tool chains if possi= ble.

Liming,
 
For gcc/clang if you repeat an= argument the last argument wins. This is the default behavior and it does = not warn, as it is designed to work with features like PcdOptimizeComp= ilerEnable. 
 
=
If VC++ warns fo= r this behavior should we disable D9025 for VC++ so all the toolchains= have the same behavior?

Hi, Liming= :
Thanks for your explanation.
 
If setting PcdOptimizeCompilerEnable as disable, then will ca= use D9025 compiling warning.
Such as:
cl : Command line warning D9025 : overriding '/O1' with '/Od'
 
So, is it ok?

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

PcdOptimizeCompilerEnable is one feature PCD d= efined 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.
