recordmcount.pl: Add support for __fentry__ 2013-11-05T21:07:50+00:00 Jamie Iles jamie.iles@oracle.com 2013-11-05T10:42:09+00:00 f02b625d0341519238ab3d9cc8706ff4bd45fb89 With gcc 4.6.0 the -mfentry feature places the function profiling call at the start of the function. When this is used, the call is to __fentry__ and not mcount. This is required for Ksplice as the C version of recordmcount doesn't insert section symbols for the __mcount_loc section so we fall back to the perl version. Based on 48bb5dc6cd9d30fe0d594947563da1f8bd9abada (ftrace: Make recordmcount.c handle __fentry__).
