--- Comment #1 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Jose E. Marchesi <jema...@gcc.gnu.org>: https://gcc.gnu.org/g:4be3919fb75e3d2a4d2bb80ba33c14e0973bc08f commit r14-2749-g4be3919fb75e3d2a4d2bb80ba33c14e0973bc08f Author: Jose E. Marchesi <jose.march...@oracle.com> Date: Mon Jul 24 15:57:05 2023 +0200 bpf: sdiv/smod are now part of BPF V4 We used to support signed division and signed modulus instructions in the XBPF GCC-specific extensions to BPF. However, BPF catched up by adding these instructions in the V4 of the ISA. This patch changes GCC in order to use sdiv/smod instructions when -mcpu=v4 or higher. The testsuite and the manual have been updated accordingly. Tested in bpf-unknown-none. gcc/ChangeLog PR target/110783 * config/bpf/bpf.opt: New command-line option -msdiv. * config/bpf/bpf.md: Conditionalize sdiv/smod on bpf_has_sdiv. * config/bpf/bpf.cc (bpf_option_override): Initialize bpf_has_sdiv. * doc/invoke.texi (eBPF Options): Document -msdiv. gcc/testsuite/ChangeLog PR target/110783 * gcc.target/bpf/xbpf-sdiv-1.c: Renamed to sdiv-1.c * gcc.target/bpf/xbpf-smod-1.c: Renamed to smod-1.c * gcc.target/bpf/sdiv-1.c: Renamed from xbpf-sdiv-1.c, use -mcpu=v4. * gcc.target/bpf/smod-1.c: Renamed from xbpf-smod-1.c, use -mcpu=v4. * gcc.target/bpf/diag-sdiv.c: Use -mcpu=v3. * gcc.target/bpf/diag-smod.c: Likewise.
