From 75737c36d52640dd9701531beedf347876ab3b94 Mon Sep 17 00:00:00 2001 From: Kugan Date: Sat, 3 May 2025 17:52:22 -0700 Subject: [PATCH 4/4] [AUTOFDO][AARCH64] Add support for profilebootstrap Add support for autoprofiledbootstrap in aarch64. This is similar to what is done for i386. Added gcc/config/aarch64/gcc-auto-profile for aarch64 profile creation. How to run: configure --with-build-config=bootstrap-lto make autoprofiledbootstrap ChangeLog: * Makefile.def: AUTO_PROFILE based on autofdo_target. * Makefile.in: Likewise. * configure: Regenerate. * configure.ac: Set autofdo_target. gcc/ChangeLog: * config/aarch64/gcc-auto-profile: New file.
