...1 above. The command line is converted into a sequence of options and resolved by the LLVM backend. This means that Clang does not know exactly what will be enabled. It needs to know this to output the correct pre processor feature test macros. Consider this AArch64 march: -march=armv8.4-a+crypto+nosha2 The base arch is armv8.4-a, the crypto extension turns on AES/SHA2/SHA3/SM4. The nosha2 disables SHA2/SHA3 (since SHA3 is dependant on SHA2). Each of these features has an ACLE feature test macro, so Clang needs to know that nosha2 also disables SHA3.
