| instruction. If done, the instruction does a 64-bit load and that's not safe. This can happen we a subreg_to_reg 0 has been coalesced. One exception is when the instruction that folds the load is a move, then we can simply turn it into a 32-bit load from the stack slot. rdar://7170444 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81494 91177308-0d34-0410-b5e6-96231b3b80d8 | |||||
