Bug ID: 95987
Summary: Another ice during GIMPLE pass: slp
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: dcb314 at hotmail dot com
Target Milestone: ---
For this C++ code:
$ cat bug627.cc
int a;
class b {
void c();
static int f[];
};
void b::c() {
for (int d; d; ++d)
for (int e = 0; e < 6; ++e)
f[e] = e + 4 << a;
}
compiled on recent gcc trunk, does this:
$ /home/dcb/gcc/results/bin/c++ -c -w -O3 -std=c++14 bug627.cc
bug627.cc: In member function ‘void b::c()’:
bug627.cc:6:6: error: definition in block 3 follows the use
6 | void b::c() {
| ^
for SSA_NAME: a.0_16 in statement:
vect__17.12_53 = vect_cst__12 << a.0_16;
during GIMPLE pass: slp
bug627.cc:6:6: internal compiler error: verify_ssa failed
0x13fa7db verify_ssa(bool, bool)
../../trunk.git/gcc/tree-ssa.c:1208
0x108dde5 execute_function_todo
../../trunk.git/gcc/passes.c:1992
The bug seems to first occur sometime between 20200624 and 20200625.
