H A D | Makefile | 90fa9deb Fri May 16 03:41:11 CDT 2014 Jean Pihet <jean.pihet@linaro.org> perf tests: Add dwarf unwind test on ARM
Adding dwarf unwind test, that setups live machine data over the perf test thread and does the remote unwind.
Need to use -fno-optimize-sibling-calls for test compilation, otherwise 'krava_*' function calls are optimized into jumps and omitted from the stack unwind.
So far it was enabled only for x86.
