Subject: [PATCH] AArch64 - Add parameter to __mount routine
Authentication-results: sourceware.org; auth=none

Hi Maintainers,

Attached is a small patch which adds a parameter to __mcount routine.

We would like to make the compiler pass the "frompc" address from the function
that calls __mcount during profiling.

ref: http://gcc.gnu.org/ml/gcc-patches/2013-08/msg01556.html

This patch is cross tested in ARMV8 foundation model. No new regressions found.

If it is ok, someone please commit on my behalf.

        * sysdeps/aarch64/machine-gmon.h (__mcount): Accept parameter and
          pass it to mcount_internal.

regards,
Venkat.
