linux-generic: add stacktrace
Add initial version for more verbose stacktrace for linux-
generic odp platform.
Usage:
export ODP_STACKTRACE_ENABLE=y
Thread 0 terminated with signal=11 (SIGSEGV)
./test/performance/odp_scheduling[0x4250b3]
/lib/x86_64-linux-gnu/libpthread.so.0(+0x10330)[0x7f7ae5cc1330]
./test/performance/odp_scheduling[0x40a064]
./test/performance/odp_scheduling(main+0x2c1)[0x40a5dc]
/lib/x86_64-linux-gnu/libc.so.6(__libc_start_main+0xf5)[0x7f7ae590df45]
./test/performance/odp_scheduling[0x408ed9]
odp_stacktrace.c:57:fault_handler():Program interrupted
Aborted
Then convert address to function symbol with add2line:
addr2line -e ./test/performance/odp_scheduling 0x4250b3
/opt/Linaro/odp3.git/platform/linux-generic/odp_stacktrace.c:49
