Profiling does not work on ARM with gcc 2.95. There are two problems:
- the cc1 specs seem to be missing %{profile:-p}, so "-profile" doesn't
actually enable profiling code generation (though -p/-pg works)
- the generated profiling code is incorrect: it contains a stray data
word after the call to mcount.
It probably needs something like this adding to linux-elf.h:
/* Call the function profiler with a given profile label. */
#undef FUNCTION_PROFILER
#define FUNCTION_PROFILER(STREAM, LABELNO) \
{ \
fprintf (STREAM, "\tbl\tmcount%s\n", NEED_PLT_RELOC ? "(PLT)" : ""); \
}
#undef CC1_SPEC
#define CC1_SPEC "%{profile:-p}"
