Sorry for inconvenience, David.
I've tested it thoroughly on x86/x86-64 and ppc a few days ago but it
looks like I used LRA. PPC was not so interested for me as this patch
affects mostly two-op insn architectures. The problem is specific only
for reload and occurs when we reassign pseudo from the reload pass.
I've just committed the patch fixing this.
Sorry again.
