This is a cleanup patch -- we're now able to support all flavours of variable location in instruction referencing mode. This patch updates various tests for debug instructions to be broader: numerous code paths try to ignore debug isntructions, and they now have to ignore the additional DBG_PHI and DBG_INSTR_REFs that we can generate. A small amount of rework happens for LiveDebugVariables: as we don't need to track live intervals through regalloc any more, we can get away with unlinking debug instructions before regalloc, then re-inserting them after. Note that this isn't (yet) true of DBG_VALUE_LISTs, they still have to go through live interval tracking. In SelectionDAG, add a helper lambda that emits half-formed DBG_INSTR_REFs for arguments in instr-ref mode, DBG_VALUE otherwise. This is one of the final locations where DBG_VALUEs are emitted for vreg arguments. X86InstrInfo now un-sets the debug instr number on SUB instructions that get mutated into CMP instructions. As the instruction no longer computes a subtraction, we can't use it for variable locations. Differential Revision: https://reviews.llvm.org/D88898 |
