== Progress == * AARCH64 - gprof support. Completed gprof -c support for aarch64. Got reviewed internally by Matt and Will. Patch yet to be posted. Waiting for some feedback on copyright message. *Testing GCC bootstrap and regression suite. Created a large image with help of Bero. Bootstrap fails with GCC trunk libgcc_eh.a (unwind-dw2-fde-dip.o) hidden symbol __register_frame_info is referenced bu DSO ld final link Bad value. Drilling down == Plan == * Post patches in gcc and binutils for gprof work * Continue handling builtin_return_address when -fomit-frame-pointer is enabled. * Continue gcc bootstrap and regression test.
