Summary: [tree-ssa] ICE in tree-flow-inline.h with "-O -fssa" but
not with "-O"
Product: gcc
Version: tree-ssa
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: c
AssignedTo: unassigned at gcc dot gnu dot org
ReportedBy: steven at gcc dot gnu dot org
CC: dnovillo at redhat dot com,gcc-bugs at gcc dot gnu dot
org
The following:
void
foo (void)
{
goto loop_entry;
loop_start:
loop_entry:
goto loop_start;
loop_exit:
}
compiles with just "-O" but segfaults with "-O -fssa"
Normally I wouldn't give a s... about -fssa, but:
a) this test case was deduced from gcc.dg/20020304-1.c which
also ICEs on the tree-ssa branch on a sanity check after
-fssa-ccp. This new ICE might be related, perhaps we just
compute broken dominance information for RTL???
b) this ICE happens in tree-flow-inline.h according to gdb:
Program received signal SIGSEGV, Segmentation fault.
compute_dominance_frontiers_1 (frontiers=0x8627520, idom=0x8627610, bb=0,
done=0x86275f8) at tree-flow-inline.h:270
270 tree-flow-inline.h: No such file or directory.
in tree-flow-inline.h
Weird to have a tree-ssa failure with RTL SSA, but in tree-ssa code!

Parts of the common code that used to exist in RTL SSA has been moved
into the tree-* files to make it easier to remove the RTL SSA stuff at a
later date.

So the decision has been made and RTL SSA is going to be wiped away? We
were just discussing this on IRC :) I thought Jeff still had plans with
it??

Dunno. I thought it was going to be removed, but I haven't been paying
much attention to that issue.

OK then. Let's XFAIL gcc.dg/20020304-1.c and close this report.

Closing as will not fix as -fssa has now been removed from the mainline and the tree-ssa.
