== Progress == * AARCH64 - gprof support. Submitted GCC patches to generate profile call. Also applied the review comments from Marcus and tested patches for aarch64-none-elf. http://gcc.gnu.org/ml/gcc-patches/2013-05/msg00597.html

* Setup a Ubuntu machine at Office. Ran GCC testsuite with on openembeded/V8 model ref: http://people.linaro.org/~hrw/oe/vekumar/. This image has updated gcc and glibc and enables gprof. During bootstrap GCC build failed due to space getting over. Need to create a larger image.

* Looking at how to handle builtin_return_address when -fomit-frame-pointer is enabled. GCC saves frame pointer for the function alone where builtin_return_address is used. Callers of the function may not have set up the frame yet.

== Plan == * Continue gprof "-c" option support in binutils * Continue handling builtin_return_address when -fomit-frame-pointer is enabled. * Continue gcc bootstrap and regression suite after creating a larger image.
