[llvm-commits] [PATCH] [bug fix] llc -regalloc=basic -verify-regalloc: Don't say "unallocated live vreg" for vreg with empty live range

[Patrik Hägglund H]

Hi,

This patch fix a problem in RegAllocBase::verify(). Currently it complains "unallocated live vreg", even if the live range is empty for the vreg.

There is also a test file attached, that triggers this problem on x86_64, generated with llvm-stress.
