Bug ID: 111548
Summary: RISC-V Vector: ICE in validate_change_or_fail (vsetvl
pass)
Product: gcc
Version: 14.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: middle-end
Assignee: unassigned at gcc dot gnu.org
Reporter: jeremy.bennett at embecosm dot com
Target Milestone: ---
Created attachment 55973

Reproducer source code
This issue was identified building SPEC CPU 2017 602.gcc_s.
Reproducer (test.c):
a, c, d;
*b;
h() {
int e;
i();
for (;;) {
unsigned f;
char *g;
f = a;
for (; f; f--) {
if (*g == '"')
e = !e;
*b = g++;
}
if (c)
break;
f = d;
for (; d;)
if (e)
b++;
}
}
Compile with:
riscv64-unknown-linux-gnu-gcc -w -march=rv64gcv -mabi=lp64d -c -Ofast \
-ftree-vectorize --param=riscv-autovec-preference=scalable test.c
Output is:
during RTL pass: vsetvl
test.c: In function 'h':
test.c:22:1: internal compiler error: in validate_change_or_fail, at

RISC-V: Fix AVL/VL bug of VSETVL PASS[PR111548]
This patch fixes that AVL/VL reg incorrect fetch in VSETVL PASS.
C/C++ regression passed.
But gfortran didn't run yet. I am still finding a way to run it.
Will commit it when I pass the fortran regression.

Confirmed that the test now passes, as indeed does SPEC CPU 2017 602.gcc_s.
Thanks for the fix. Marking as resolved.
