From: Jeff Law <law@gcc.gnu.org> To: gcc-cvs@gcc.gnu.org Subject: [gcc(refs/vendors/riscv/heads/gcc-13-with-riscv-opts)] RISC-V/testsuite: Add branched cases for GEU and LEU cond-move operations Date: Wed, 22 Nov 2023 05:10:08 +0000 (GMT) [thread overview] Message-ID: <20231122051008.9F3D13858CD1@sourceware.org> (raw) https://gcc.gnu.org/g:f3e368a722e550ff32bc76d6da555e824e07c4ca commit f3e368a722e550ff32bc76d6da555e824e07c4ca Author: Maciej W. Rozycki <macro@embecosm.com> Date: Wed Nov 22 01:18:26 2023 +0000 RISC-V/testsuite: Add branched cases for GEU and LEU cond-move operations Verify, for Ventana and Zicond targets and the GEU and LEU conditional-move operations, that if-conversion does *not* trigger at `-mbranch-cost=3' setting, which makes original branched code sequences cheaper than their branchless equivalents if-conversion would emit. gcc/testsuite/ * gcc.target/riscv/movdibgtu-ventana.c: New test. * gcc.target/riscv/movdibgtu-zicond.c: New test. * gcc.target/riscv/movdibltu-ventana.c: New test. * gcc.target/riscv/movdibltu-zicond.c: New test. * gcc.target/riscv/movsibgtu-ventana.c: New test. * gcc.target/riscv/movsibgtu-zicond.c: New test. * gcc.target/riscv/movsibltu-ventana.c: New test. * gcc.target/riscv/movsibltu-zicond.c: New test.
