Dimitry Andric 86a34ce5a4 Pull in r300404 from upstream llvm trunk (by me): ... Use correct registers for "A" inline asm constraint Summary: In PR32594, inline assembly using the 'A' constraint on x86_64 causes llvm to crash with a "Cannot select" stack trace. This is because `X86TargetLowering::getRegForInlineAsmConstraint` hardcodes that 'A' means the EAX and EDX registers. However, on x86_64 it means the RAX and RDX registers, and on 16-bit x86 (ia16?) it means the old AX and DX registers. Add new register classes in `X86RegisterInfo.td` to support these cases, and amend the logic in `getRegForInlineAsmConstraint` to cope with different subtargets. Also add a test case, derived from PR32594. Reviewers: craig.topper, qcolombet, RKSimon, ab Reviewed By: ab Subscribers: ab, emaste, royger, llvm-commits Differential Revision: https://reviews.llvm.org/D31902 This should fix crashes when using the 'A' constraint on amd64, for example as it is being used in Xen.
