[PATCH] D86889: [AArch64] Add asm directives for the remaining SEH unwind codes

[Eli Friedman via Phabricator via llvm-commits]

efriedma added a comment.

Adding assembler support for the basic opcodes we left out because the code generator doesn't use them seems fine.  We could teach the assembler to optimize certain constructs: for example, turn save_regp_x into save_r19r20_x if the register matches and the offset is in range.  Might be more confusing than helpful, though.

For the custom stack opcodes, do you have some intended use?  If we just want to allow people to dump random bytes into the unwind opcode list, we could add a directive for that, without trying to come up with an appropriate name for opcodes that aren't really documented.
