--- Comment #4 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The trunk branch has been updated by Andrew Pinski <pins...@gcc.gnu.org>: https://gcc.gnu.org/g:d3ff08a3764f2047d02b35212fc4f1da9eb75c7b commit r14-8397-gd3ff08a3764f2047d02b35212fc4f1da9eb75c7b Author: Andrew Pinski <quic_apin...@quicinc.com> Date: Thu Jan 18 10:40:04 2024 -0800 aarch64: Fix __builtin_apply with -mgeneral-regs-only [PR113486] The problem here is the builtin apply mechanism thinks the FP registers are to be used due to get_raw_arg_mode not returning VOIDmode. This fixes that oversight and the backend now returns VOIDmode for non-general-regs if TARGET_GENERAL_REGS_ONLY is true. Built and tested for aarch64-linux-gnu with no regressions. PR target/113486 gcc/ChangeLog: * config/aarch64/aarch64.cc (aarch64_get_reg_raw_mode): For TARGET_GENERAL_REGS_ONLY, return VOIDmode for non-GP_REGNUM_P regno. gcc/testsuite/ChangeLog: * gcc.target/aarch64/builtin_apply-1.c: New test.
