Bug ID: 63908
Summary: [e500v2] "float_bessel"case failed on e500v2 platforms
Product: gcc
Version: 4.9.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: leimaohui at cn dot fujitsu.com
I used yocto 1.7 to make a rootfs and toolchain.And then test LTP.
gcc :4.9.1
kernel :3.4.74
LTP version: 20120903
Some cases failed in powerpc e500v2. But these cases are PASS in i586 and
armv7.
'float_bessel' is one of the failed cases. The log likes below:
###################################
float_bessel 1 TPASS : Test passed
float_bessel 0 TINFO : float_bessel: will run for 500 loops; using . as a
data directory
float_bessel 0 TINFO : float_bessel: will run 5 functions, 20 threads per
function
float_bessel 0 TINFO : signal handler 1216373856 started
float_bessel 0 TINFO : Signal handler starts waiting...
float_bessel 0 TINFO : initial thread: Waiting for 100 threads to finish
sh: line 1: 12822 Aborted float_bessel -v
###################################
In addition,'float_exp_log','float_iperb','float_power'and 'float_trigo' are
failed and have the similar phenomenon.
Steps:
######
1. root@localhost:~# cd /opt/ltp/
2. root@localhost:/opt/ltp# ./runltp -s float_bessel
######
Is there anybody give me some suggestions?
