Bug ID: 105431
Summary: ICE: SIGSEGV in powi_as_mults_1
(tree-ssa-math-opts.cc:1512) with -Ofast and
__builtin_pow()
Product: gcc
Version: 13.0
Status: UNCONFIRMED
Keywords: ice-on-valid-code
Severity: normal
Priority: P3
Component: tree-optimization
Assignee: unassigned at gcc dot gnu.org
Reporter: zsojka at seznam dot cz
Target Milestone: ---
Host: x86_64-pc-linux-gnu
Target: x86_64-pc-linux-gnu
Created attachment 52903
--> https://gcc.gnu.org/bugzilla/attachment.cgi?id=52903&action=edit
reduced testcase
This might be related to PR105368; on 11-branch and older, the other PR is
triggered. The failing address is also very similar to the other PR.
This fails for me only with a bootstrapped compiler; there might be another UB
that is exploited only when bootstrapping.

While you touch it, shouldn't e.g.
/* Avoid largest negative number. */
if (n != -n
be fixed as well (don't we fold that as n != 0?)?

Yeah, that probably guarded against the other misuses of -n ... in
fact we should handle the most negative number fine now so I'm
going to just remove this check (n == 0 is also handled well).

Thank you, I missed that "(n < 0) ? -n : n" in the code...
I can confirm the compiler bootstraps, and no longer crashes on the testcase.
I didn't try to run the testsuite.

PR tree-optimization/105431
* tree-ssa-math-opts.c (powi_as_mults_1): Make n unsigned.
(powi_as_mults): Use absu_hwi.
(gimple_expand_builtin_powi): Remove now pointless n != -n
check.
