Emulator test failures are sometimes hard to debug, especially when the test is stuck somewhere and times out. Let's have the emulator dump stack trace when an assertion fails or a test times out. The produced stack trace is in this format: #0 build/host/kb_8042/kb_8042.exe() [0x412421] /home/victoryang/trunk/src/platform/ec/test/kb_8042.c:104 #1 build/host/kb_8042/kb_8042.exe() [0x4124a9] /home/victoryang/trunk/src/platform/ec/test/kb_8042.c:129 #2 build/host/kb_8042/kb_8042.exe(run_test+0x3a) [0x412e2c] /home/victoryang/trunk/src/platform/ec/test/kb_8042.c:262 #3 build/host/kb_8042/kb_8042.exe(_run_test+0x11) [0x4061de] /home/victoryang/trunk/src/platform/ec/core/host/task.c:90 #4 build/host/kb_8042/kb_8042.exe(_task_start_impl+0x79) [0x406b72] /home/victoryang/trunk/src/platform/ec/core/host/task.c:408 #5 /lib64/libpthread.so.0(+0x70b1) [0x7f6dc2fa10b1] ??:0 #6 /lib64/libc.so.6(clone+0x6d) [0x7f6dc2cd8efd] ??:0 The file name and line number in the trace is generated by addr2line. BUG=chrome-os-partner:19235 chromium:331548 TEST=Put in a infinite loop in a test, and see stack trace when it times out. TEST=Add a failing assertion, and see stack trace when it fails.
