llvm-as wouldn't recognize pmull instruction without adding -march=armv8-a+crypto flag at least with the version I use "3.8.1" I tried both .arch armv8-a+crypto and .arch_extension crypto and they worked only for gas while llvm-as produces errors for pmull using.
Is there any documentation for llvm-as? Best I could find is the minimal man page https://www.llvm.org/docs/CommandGuide/llvm-as.html, with no info whatsoever on, e.g., supported pseudoops.
