This adds support for the last missing construct to parse TLS-related assembler code: add 3, 4, symbol@tls The ADD8TLS currently hard-codes the @tls into the assembler string. This cannot be handled by the asm parser, since @tls is parsed as a symbol variant. This patch changes ADD8TLS to have the @tls suffix printed as symbol variant on output too, which allows us to remove the isCodeGenOnly marker from ADD8TLS. This in turn means that we can add a AsmOperand to accept @tls marked symbols on input. As a side effect, this means that the fixup_ppc_tlsreg fixup type is no longer necessary and can be merged into fixup_ppc_nofixup. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@185692 91177308-0d34-0410-b5e6-96231b3b80d8
