Bug ID: 100519
Summary: ICE in insert_stmt_after, at tree-ssa-reassoc.c:1452
Product: gcc
Version: 11.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: regression
Assignee: unassigned at gcc dot gnu.org
Reporter: marxin at gcc dot gnu.org
Target Milestone: ---
Host: x86_64-linux-gnu
Target: s390x-linux-gnu
The following fails, likely a recent regression:
$ cat asmgoto.c
int foo_a1, foo_a2;
int foo() {
int v0, x;
asm goto("" : "=r"(x) : : : lab);
lab:
v0 += x + x;
return v0 + x + foo_a1 + foo_a2;
}
$ s390x-linux-gnu-gcc asmgoto.c -fwrapv --param=tree-reassoc-width=2 -O2
during GIMPLE pass: reassoc
asmgoto.c: In function ‘foo’:
asmgoto.c:4:5: internal compiler error: in insert_stmt_after, at
tree-ssa-reassoc.c:1452
4 | int foo() {
