Bug ID: 108970
Summary: [13 Regression] ICE in vect_do_peeling, at
tree-vect-loop-manip.cc:2971, or ICE in
dump_printf_loc, at dumpfile.cc:1359
Product: gcc
Version: 13.0
Status: UNCONFIRMED
Keywords: ice-on-valid-code
Severity: normal
Priority: P3
Component: tree-optimization

Target Milestone: ---
1. gcc 13.0.1 20230226 snapshot (g:e6d39f68d03c46637ca6e1bede3d28eae6278df3)
ICEs when compiling the following testcase w/ -O1 -ftree-loop-vectorize

Confirmed. I will have a look. Without -fsave-optimization-record it ICEs
with

tree-optimization/108970 - ICE with vectorizer peeling
The function slpeel_can_duplicate_loop_p fails to verify we can
copy blocks, instead slpeel_tree_duplicate_loop_to_edge_cfg does
but that's too late. The following fixes this, also simplifying
error reporting which is somewhat pointless if we ICE immediately.
PR tree-optimization/108970
* tree-vect-loop-manip.cc (slpeel_can_duplicate_loop_p):
Check we can copy the BBs.
(slpeel_tree_duplicate_loop_to_edge_cfg): Avoid redundant
check.
(vect_do_peeling): Streamline error handling.
* gcc.dg/pr108970.c: New testcase.

The issue is latent of course, but unlikely to hit us in practice.
