Hi Geoff,
I see the MachineVerifier complaining after this commit for our out-of-tree target. More over, address sanitizer is complaining about an invalid access.
==50770==ERROR: AddressSanitizer: SEGV on unknown address 0x000000000008 (pc 0x000102e7e42e bp 0x700002f37170 sp 0x700002f36f60 T9)
==50770==The signal is caused by a READ memory access.
==50770==Hint: address points to the zero page.
#0 0x102e7e42d in (anonymous namespace)::MachineCopyPropagation::forwardUses(llvm::MachineInstr&) MachineCopyPropagation.cpp:596
#1 0x102e79c22 in (anonymous namespace)::MachineCopyPropagation::runOnMachineFunction(llvm::MachineFunction&) MachineCopyPropagation.cpp:806
The MachineVerifier error is:
*** Bad machine code: Instruction ending live segment doesn't read the register ***
Could you revert while we investigate?
Thanks,
-Quentin
