Bug ID: 59728
Summary: gcc.target/mips/octeon-baddu-1.c is failing (finds 3
double adds instead of 4)
Product: gcc
Version: 4.9.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: sje at gcc dot gnu.org
CC: pinskia at gcc dot gnu.org, rdsandiford at googlemail dot com
Target: mips*-*-*
The test gcc.target/mips/octeon-baddu-1.c started failing for me on Dec 10,
2013. The test expects to find 4 baddu instructions and no andi instructions
when compiled with -march=octeon but is now using 3 daddu instructions and 1
addu instruction instead of baddu instructions and it is also generating andi
instructions. I am not sure exactly what checkin caused this change or if the
change in generated code is correct or not.
PASS: gcc.target/mips/octeon-baddu-1.c -O2 (test for excess errors)
FAIL: gcc.target/mips/octeon-baddu-1.c -O2 scan-assembler-times \tbaddu\t 4
FAIL: gcc.target/mips/octeon-baddu-1.c -O2 scan-assembler-not \tandi\t
