Description
The fix for 6792161 creates situations in the scheduler where the verification of the def/use of registers fails, again because the precedence edge isn't a real use.  I think the fix has to be revisited.
On 01/29 a bunch of tests in Comp_Baseline failed:
#  Internal Error
(/tmp/jprt/P1/B/173357.kvn/source/src/share/vm/opto/output.cpp:2381),
pid=8, tid=9
#  Error: after block local scheduling
