JDK-6913296 - CTW with -XX:+AggressiveOpts fails jdk7-64bit/hotspot/src/share/vm/opto/matcher.cpp:1396
Description
We are missing the most of the unsigned CMove match rules on sparc.
Comments
EVALUATION Sparc was missing the unsigned compare cmove patterns which could be emitted as a result of some optimizations which are currently guarded under AggressiveOpts. The fix is simply to add these patterns. Tested with new test case.
