Bug ID: 116608
Summary: i386/xorsign.c, i386/vect-double-2.c fail with
-march=x86-64-v2(-msse4).
Product: gcc
Version: 15.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: testsuite
Assignee: unassigned at gcc dot gnu.org
Reporter: lin1.hu at intel dot com
Target Milestone: ---
gcc.target/i386/xorsign.c and gcc.target/i386/vect-double-2.c will fail with
-march=x86-64-v2
53 PASS: gcc.target/i386/xorsign.c execution test
54 gcc.target/i386/xorsign.c: pattern found 0 times
55 FAIL: gcc.target/i386/xorsign.c scan-tree-dump-times vect "vectorized 2
loops" 1
56 PASS: gcc.target/i386/xorsign.c scan-assembler [ \t]xor
57 PASS: gcc.target/i386/xorsign.c scan-assembler [ \t]and
With sse4, gcc will vectorized 4 loops. I want to add an extra option -mno-sse4
in these testcases.
