Bug ID: 124481
Summary: gcc.dg/tree-ssa/ssa-dom-cse-2.c FAILs
Product: gcc
Version: 16.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: tree-optimization
Assignee: unassigned at gcc dot gnu.org
Reporter: ro at gcc dot gnu.org
CC: rguenth at gcc dot gnu.org
Target Milestone: ---
Target: sparc-sun-solaris2.11
The gcc.dg/tree-ssa/ssa-dom-cse-2.c test FAILs with a Solaris/SPARC compiler
with -m64 in a weird way:
* trunk, 32-bit compiler, -m64:
PASS: gcc.dg/tree-ssa/ssa-dom-cse-2.c (test for excess errors)
FAIL: gcc.dg/tree-ssa/ssa-dom-cse-2.c scan-tree-dump optimized "return 28;"
* trunk, 64-bit compiler, -m64:
PASS: gcc.dg/tree-ssa/ssa-dom-cse-2.c (test for excess errors)
PASS: gcc.dg/tree-ssa/ssa-dom-cse-2.c scan-tree-dump optimized "return 28;"
On the gcc-15 branch instead, at least 32 and 64-bit compilers were consistent:
* gcc-15 branch, 32 and 64-bit compiler, -m64:
PASS: gcc.dg/tree-ssa/ssa-dom-cse-2.c (test for excess errors)
XFAIL: gcc.dg/tree-ssa/ssa-dom-cse-2.c scan-tree-dump optimized "return 28;"
I'm attaching the dumps for both cases. The gcc-15 (32 and 64-bit) and trunk
(32-bit) dumps are identical.
