Hi Matthew,
I am not seeing large differences in size using the default flags from
tools_def.txt.
Here are some measurements of the DxeCore.efi module in MdeModulePkg/Core/Dxe.
I have included the LZMA compressed size too because that the most common
compression for FVs/Modules.

Do you have an example of an EDK II module that exhibits the large size
differences you are seeing using the default flags from tools_def.txt?
Thanks,
Mike

Subject: [edk2] VS tools version and code size
I have noticed that while compiling using Visual Studio 2008 the code size is
much smaller compared to using a later version of Visual Studio, like 2012.
Does anyone have any experience as to why that is? Are there any recommended
configurations or changes needed when using a later version of Visual studio
not add to the output code size? Thanks for any recommendations or explications.
