There have been several fixes in the last couple of days. This is the
current state of regressions vs mainline:
New regressions in gcc.sum.gz:
FAIL: gcc.dg/debug/dwarf2/dwarf-die7.c scan-assembler 1.*DW_AT_inline
FAIL: 209: expected branch percentages not found: 25
FAIL: gcc.misc-tests/gcov-4b.c gcov: 0 failures in line counts
The dwarf2 regression may be related to one of the PRs opened by
mec (PR 14048, PR 14049). I do not know yet whether it's
reasonable to wait after the merge to fix this one (rth?).
The two others require that we build a flowgraph at -O0. I
would like to leave these until after the merge.
New regressions in g++.sum.gz:
FAIL: g++.dg/parse/stack1.C (test for excess errors)
This one requires an extensive modification to the gimplifier to
avoid deep recursion. This will have to be fixed after the
merge.
FAIL: 258: expected branch percentages not found: 25
FAIL: g++.dg/gcov/gcov-1.C gcov: 0 failures in line counts
FAIL: 23:is 2:should be 1
FAIL: g++.dg/gcov/gcov-2.C gcov: 1 failures in line counts
Similar to the GCC tests. We need the flowgraph at -O0. Post
merge.
FAIL: g++.old-deja/g++.brendan/crash13.C (test for errors
FAIL: g++.old-deja/g++.bugs/900205_03.C (test for errors
FAIL: g++.old-deja/g++.bugs/900205_03.C (test for errors

These are diagnostics that are either not emitted or at
different lines. Jason, are they fixable pre-merge?
New regressions in libffi.sum.gz:
NONE
New regressions in libjava.sum.gz:
FAIL: Array_3 execution - gij test
FAIL: Array_3 execution - gij test
In [link] aph says that it's a C++ bug. We are generating bad
EH code. rth?
FAIL: PR4766 -O3 compilation from source
FAIL: String_overflow -O3 compilation from source
FAIL: err3 output - source compiled test
FAIL: err3 -O3 output - source compiled test
Andrew, what should we do with these?
Fixed regressions in libjava.sum.gz:
FAIL: Thread_Monitor execution - gij test
At least one test where the branch does better.
New regressions in libstdc++-abi.sum.gz:
NONE
New regressions in libstdc++.sum.gz:
NONE
New regressions in objc.sum.gz:
NONE
