Thanks for the information. I haven't seen that yet, but I'll try (no need
for you to bother with creating a test case).
I've updated the patch to set global/fixed/uneliminated regs as live
throughout the function, and not to create REG_UNUSED notes for all
call-clobbered regs on every function call. I'll send a new version as soon
as I've tested it a bit more.
