Bug ID: 100292
Summary: [12 Regression] ICE: verify_gimple failed: invalid
operands in ternary operation (during GIMPLE pass:
veclower) with vectors
Product: gcc
Version: 12.0
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
Created attachment 50690
--> https://gcc.gnu.org/bugzilla/attachment.cgi?id=50690&action=edit
reduced testcase
This seems to be a recent regression; r12-100 is OK, r12-159 is BAD.
I searched the bug database, and even though I am triggering this often on
various targets, I didn't find any duplicate.
Compiler output:
$ x86_64-pc-linux-gnu-gcc testcase.c
testcase.c: In function 'foo':
testcase.c:6:1: error: invalid operands in ternary operation
6 | foo (char c)
| ^~~
_13 = (signed char) c.1_2 >= 0 ? -1 : 0;
during GIMPLE pass: veclower
testcase.c:6:1: internal compiler error: verify_gimple failed

tree-optimization/100292 - avoid invalid GIMPLE from vector lowering
We have to avoid folding the condition when building a COND_EXPR
since we no longer gimplify the whole thing. The folding done
at COND_EXPR build time will deal with possible simplifications.
