[Bug tree-optimization/21448] New: [4.1 Regression] ICE in estimate_num_insns_1, at tree-inline.c:1433

["jsm28 at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

The following test failures have appeared on mainline between 20050506 and
20050507.  All are "internal compiler error: in estimate_num_insns_1, at
tree-inline.c:1433".

On i686-pc-linux-gnu and ia64-hpux:

FAIL: gcc.dg/vect/vect-ifcvt-2.c (test for excess errors)
FAIL: gcc.dg/vect/vect-ifcvt-3.c (test for excess errors)
FAIL: gcc.dg/vect/vect-ifcvt-4.c (test for excess errors)
FAIL: gcc.dg/vect/vect-ifcvt-5.c (test for excess errors)
FAIL: gcc.dg/vect/vect-ifcvt-6.c (test for excess errors)
FAIL: gcc.dg/vect/vect-ifcvt-7.c (test for excess errors)
FAIL: gcc.dg/vect/vect-ifcvt-9.c (test for excess errors)
FAIL: gcc.dg/vect/vect-ifcvt-9.c scan-tree-dump-times vectorized 1 loops 2

On i686-pc-linux-gnu (not a new failure on ia64-hpux because of bug 21050, but
the ICE has become the same as the one above):

FAIL: gcc.dg/vect/vect-none.c (test for excess errors)

On ia64-hpux (both -milp32 and -mlp64), same ICE:

FAIL: gcc.dg/tree-ssa/ifc-20040816-1.c (test for excess errors)

gcc-testresults shows at least some of these tests failing on other platforms,
which may be the same failure.
