[edk2-devel] [PATCH v5 0/2] CryptoPkg/OpensslLib: Add native instruction support for X64

Their options would be:
1) File a bug against OpenSSL that their NASM code is too advanced for GCC toolchain (unlikely to result in any change since OpenSSL would say GCC build should be using GAS instead of NASM and building outside of their makefile build system is bad practice in the first place).
2) File a bug against GCC that their toolchain can't handle NASM correctly.
3) Use CLANGPDB toolchain instead.
I am not familiar enough with the GCC toolchain to know if there is any way to make it interpret NASM files correctly, so there is a chance that someone who knows more about it could provide some configuration change that could resolve this. But I do not think we should say that VS and CLANGPDB toolchain users can't have OpenSSL acceleration because GCC can't handle it.
Thanks,
Christopher Zurcher
