HelloWorld app fails in -Xem:opt mode with verification level=2
To reproduce use this params:
-Xem:opt -verbose:em -XDjit.arg.verify=2
output:

Mikhail Fursov commented on HARMONY-3183:
-----------------------------------------
Problem source:
Peephole XORPS optimization created incorrect LIR: opnds without defs.
Solution: The optimization by itself (XORPS to PXOR replacement) is useless. The fix removes this optimization.

handleInst_SSEMov was commented some time ago by performance reasons. EHWA passes in -Xem:opt debug mode now with -XX:jit.arg.verify=2

-----------------------------------------
No,
The optimization has a bug with operands handling. Instead of fixing this bug I had just removed this useless optimization.

I do not think commenting out useless code with errors will help us to create good source.
I have another suggestion: create a TODO comment with a single line "XORPS to PXOR conversion has shown itself as useless"
It's not a question how to write IR. The only loss of removal this code I see is the loss of knowledge that we already tried this out.

------------------------------------------
Mikhail, while I can admit that the optimization gives no practical boost thus is useless, I suspect the rootcause of failure resides deeper and suggested fix just hides it?

[jira] Commented: (HARMONY-3183) [drlvm][jit] HelloWorld app fails
in -Xem:opt mode with verification level=2

------------------------------------------
My assumption proves right, EHWA fails if -XDjit.arg.verify=2 and starts working if handleInst_SSEMov() is off.
Commented it out too.
