Duane,
Try adding [BuildOptions] to your DSC file.
[BuildOptions]
MSFT:*_*_*_CC_FLAGS = /Od
This appends /Od to the end of the set of flags for every compile operation.
For VS compilers the last /O option wins.

Subject: [edk2] can we disable optimizations?
Tried today to change the VS2008 compile options from the variety of values
(/Oi- /O1bi2s etc.) to /Od and ran into several issues. (1) is that there
isn't one place where we can set a single optimization value. But it looks
like StdLib libs and AppPkg apps actually require different levels of
optimizations as various intrinsic functions (like abs and memcpy) are not
implemented - thus requiring the compiler to provide them. Has anyone managed
to disable VS2008 optimizations in EDK2?
Why would I try this? Various stack dump utilities I have claim to be able to
understand un-optimized MSC++ stack frames and they arn't working. The
suggestion was made to try to disable optimization.
So I reverted all my .inf file changes and then got this:
c:\.....\edk2\stdlib\libc\gdtoa\strtodg.c(628) : warning C4700:
uninitialized local variable 'rv' used
which is treated as an error and causes the build to fail. So, (2) has anyone
seen this problem in strtodg?
