== Progress ==

* AARCH64 - Gprof support.

Make GCC generate profile information (On-going).

Defined hook and macros in GCC to emit "mcount" instrumented calls. Looked at ARM implementation and veener code in glibc which implements mcount. Discussed with Matt, and decided to use generic "mcount" implementation in glibc for aarch64. The generic uses built_in_return_address. Looking at defining macros and function which traverses frames back and returns the desired frame address.

== Plan == * Continue gprof support work for Aarch64

Planned leaves: 1 May: Labor Day's holiday.
