[Bug middle-end/20623] ICE: fold check: original tree changed by fold with --enable-checking=fold

["ghazi at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

------- Comment #38 from ghazi at gcc dot gnu dot org  2008-01-26 05:11 -------
Update: mainline appears to pass fold checking albeit with a few extra timeouts
due to length compilation times.  However the last fix for fold checking was
never backported to the branches.  On 4.1/4.2 I still get these extra fold
checking errors due to label addresses:

FAIL: gcc.c-torture/compile/20021108-1.c
FAIL: gcc.c-torture/compile/920501-7.c
FAIL: gcc.c-torture/compile/labels-1.c
FAIL: gcc.c-torture/compile/labels-2.c
FAIL: gcc.c-torture/compile/labels-3.c
FAIL: gcc.dg/20021029-1.c
FAIL: gcc.dg/pr16973.c


Here are the latest results for x86_64-unknown-linux-gnu:
4.1 (extra errors): http://gcc.gnu.org/ml/gcc-testresults/2008-01/msg01221.html
4.2 (extra errors): http://gcc.gnu.org/ml/gcc-testresults/2008-01/msg01222.html

trunk (x86_64 ok): http://gcc.gnu.org/ml/gcc-testresults/2008-01/msg01253.html

I don't have access to solaris any more to see if there are still gomp fold
checking failures as from comment #37.
