Summary: valgrind memcheck receive SIGBUS on octeon II CPU
Product: valgrind
Version: 3.14.0
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: memcheck
Assignee: jsew...@acm.org

Target Milestone: ---
SUMMARY
valgrind memcheck receive SIGBUS on octeon II CPU CN61xx。
STEPS TO REPRODUCE
1. build a valgrind for a cavium octeonII CPU
./configure --enable-only64bit --target=mips64-octeon-linux-gnu
--host=mips64-octeon-linux-gnu --prefix=/usr --program-prefix=""
CFLAGS="-march=octeon2 -Werror"
make
gcc version is 4.7 glibc is 2.16 kernel version is 3.10 valgrind code is 3.14.0
2. try to start a program using valgrind without any param on a cavium board.
get a log like this
