Bug #: 52656
Summary: [4.8 regression] gcc.target/sparc/fpmul-2.c FAILs
Classification: Unclassified
Product: gcc
Version: 4.8.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: middle-end
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: ro@gcc.gnu.org
CC: ebotcazou@gcc.gnu.org, rguenth@gcc.gnu.org
Host: sparc-sun-solaris2*
Target: sparc-sun-solaris2*
Build: sparc-sun-solaris2*
As initially mentioned in PR testsuite/52614, gcc.target/sparc/fpmul-2.c has
recently started to fail:
FAIL: gcc.target/sparc/fpmul-2.c scan-tree-dump optimized "{ 2, 4, 6, 8 }"
It turned out that the failure is unrelated to the other ones, and a reghunt
revealed the culprit patch:
2012-03-16 Richard Guenther <rguenther@suse.de>
* tree.h (TREE_VECTOR_CST_ELTS): Remove.
(VECTOR_CST_NELTS, VECTOR_CST_ELTS, VECTOR_CST_ELT): New defines.
(struct tree_vector): Remove elements member, add variable size
elts array member.
(build_vector_stat): Declare.
(build_vector): Define in terms of build_vector_stat.
[...]
* config/sparc/sparc.c (sparc_handle_vis_mul8x16): Adjust interface
and implementation.
(sparc_fold_builtin): Adjust.
Here's the change in the optimized dumps:
