--- Comment #5 from Renato Golin <renato.golin at linaro.org> ---
I get it now. The point here is not the inline assembly mess up, but the
profiling on ARM. Yes, the inline asm is broken, but the profiler mcount should
preserve R0~R3, at least according to this document:


Maybe we need to call __gnu_mcount_nc on ARM on gnueabi mode?
