[llvm-commits] [PATCH] Fix PR11985

[Michael Liao]

Hi

The attached patch addresses the issue found in PR11985. BlockAddress
doesn't support BA + offset form and has no way to propagate offset into
machine operand if target could support that. BlockAddress node is
revised to support extra offset (0 by default.) and
getTargetBlockAddress is added (similar to other symbol reference
nodes.) X86 backend is enhanced to prepare BlockAddress with non-0
offset. All other backends are slightly modified to use the new
interface.

Thanks for your review!

Yours
- Michael
