NASM had been unable to assemble segment register operations before the following git commit:
http://repo.or.cz/nasm.git/commitdiff/21d4ccc3c338 That commit was first released in NASM 2.10: http://repo.or.cz/nasm.git/commitdiff/ff62f33da0a2 This makes NASM 2.07 unusable for edk2 in general, because now we have a lot of X64 assembly code that works with segment registers. For example in: UefiCpuPkg/Library/CpuExceptionHandlerLib/X64/ExceptionHandlerAsm.nasm Bump the minimum required version to 2.10, for use with GCC toolchains. Furthermore, list NASM 2.12.01 as a requirement for all other toolchains. In particular, for source level debugging, VS20xx requires CodeView 8 debug symbols, and only NASM 2.12.01 and later produce those. (Suggested by Liming, Mike, and Andrew.)
