Re: [edk2-devel] CryptoPkg OpensslLib INF files

["Michael D Kinney" <michael.d.kinney@intel.com>]

Hi Christopher,

I see that IA32 uses .nasm files and IA32Gcc uses .S files.

EDK II support use of NASM files from both VS and GCC builds.

Is there any reason why the .nasm files generated by OpenSSL can not 
be used for both VS and GCC builds and remove the .S files?

Thanks,

Mike
