I have a test case where the IfConversion pass adds lots of live-in regs to an MBB. At least some of these registers are in fact not live.
I wonder what can be done about this? There is some FIXME comment regarding live-ins, but I am not sure what should be done.
The most appropriate action would be to file a bug at llvm.org/bugs
Please verify the issue exists on top of trunk clang.
Also, please include your test case and the necessary command line options to reproduce the problem.
Please be descriptive in the comments and include as much detail as possible.
OK - done. See 25263 – LiveIn lists for MBBs are incorrect /Jonas
