Status of Strong PHI Elimination?

Hello,

I am implementing a code transformation that would heavily benefit from the CodeGen/StrongPHIElimination pass, but on the two bytecode files I’ve tested it on so far llc segfaults on both. I see there have been no substantive changes to this code since the middle of last year. Could someone please tell me what the status of this pass is? Thank you.

It's not production quality so I wouldn't recommend using it.

Hi Marc,

I don't know what the status is, but filing bug reports with the problematic
testcases will hopefully get things moving.

Ciao,

Duncan.

As you discovered, it's buggy, incomplete and, to my knowledge, not being worked on.
