Hi all, I need to implement profiling support for my backend (GCC 4.1.1). There is only limited information in GCC Internals to define the following macros (FUNCTION_PROFILER, PROFILE_HOOK ,NO_PROFILE_COUNTERS & PROFILE_BEFORE_PROLOGUE) to add profiling support. I need to know the following details:
1. The function mcount: While building with native gcc, the mcount function is defined in glibc. Is the same mcount function available in newlib? or is it that we have to define it in our back-end as SPARC does (gmon-sol2.c). 2. Is it possible to reuse the existing mcount definition or is it customized for every backend? 3. Any other existing back-ends that support profiling. Thanks in advance. Regards, Rohit
