Lu <hjl@gcc.gnu.org>: https://gcc.gnu.org/g:51f8ac3341078303e81e72d9013698a31c5ddd29 commit r14-8808-g51f8ac3341078303e81e72d9013698a31c5ddd29 Author: H.J. Lu <hjl.tools@gmail.com> Date: Thu Feb 1 08:02:27 2024 -0800 x86-64: Find a scratch register for large model profiling 2 scratch registers, %r10 and %r11, are available at function entry for large model profiling. But %r10 may be used by stack realignment and we can't use %r10 in this case. Add x86_64_select_profile_regnum to find a caller-saved register which isn't live or a callee-saved register which has been saved on stack in the prologue at entry for large model profiling and sorry if we can't find one. gcc/ PR target/113689 * config/i386/i386.cc (x86_64_select_profile_regnum): New. (x86_function_profiler): Call x86_64_select_profile_regnum to get a scratch register for large model profiling. gcc/testsuite/ PR target/113689 * gcc.target/i386/pr113689-1.c: New file. * gcc.target/i386/pr113689-2.c: Likewise. * gcc.target/i386/pr113689-3.c: Likewise.
