  Target Milestone: ---

Saw this on powerpc64 both LE and BE.

The revision caused some previously failing test cases to now succeed but some
different ones to start failing.

Previously it was like this:

Running /home/seurer/gcc/gcc-test/gcc/testsuite/gcc.dg/ipa/ipa.exp ...
FAIL: gcc.dg/ipa/inline-1.c scan-ipa-dump inline "op2 change 9.990000. of time"
FAIL: gcc.dg/ipa/inline-1.c scan-ipa-dump inline "op3 change 9.990000. of time"
FAIL: gcc.dg/ipa/inline-1.c scan-ipa-dump inline "op4 change 9.990000. of time"
FAIL: gcc.dg/ipa/inline-1.c scan-ipa-dump inline "op5 change 9.990000. of time"


With this revision those tests now pass but these fail:

Running /home/seurer/gcc/gcc-test2/gcc/testsuite/gcc.dg/ipa/ipa.exp ...
FAIL: gcc.dg/ipa/inline-2.c scan-ipa-dump inline "op2 change 10.000000. of
time"
FAIL: gcc.dg/ipa/inline-3.c scan-ipa-dump inline "Scaling time by
probability:0.100000"
