Andrew:
  Yes. GenFw has -z option to clear debug entry data as zero. I try GenFw with -e PEIM –z together. But, I find the generated EFI image is wrong. I have submitted BZ https://bugzilla.tianocore.org/show_bug.cgi?id=1727 for it. I will fix it.

Thanks

Liming,

Is there a way to turn it off? Does it follow the -g flag passed to the compiler? Can you post process with GenFw --zero to remove it?

Thanks,

Subject: [edk2-devel] Remove debug strings from OVMF.fd

Hi EDK2 developers,

I'm trying to build OVMF without debug symbols but even building as RELEASE, I still can see some strings on the PE files, such as:
<my-edk2-folder>/Build/OvmfX64/RELEASE_GCC5/X64/MdeModulePkg/Application/UiApp/UiApp/DEBUG/UiApp.dll
and many others in the format */DEBUG/*.dll

Is there a way to build without these strings?

Thanks!
