--- Comment #10 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Segher Boessenkool <seg...@gcc.gnu.org>: https://gcc.gnu.org/g:7194397966e6a007cee42360f96834377c3121a4 commit r12-6047-g7194397966e6a007cee42360f96834377c3121a4 Author: Segher Boessenkool <seg...@kernel.crashing.org> Date: Fri Dec 17 16:59:55 2021 +0000 rs6000: Redo darn (PR103624) The builtins now all return "long". The patterns have :GPR as the output mode, so they can be 32-bit as well (the instruction makes sense in 32 bit just fine). The builtins expand to the DImode version normally, but to the SImode if {32bit} is true. 2021-12-17 Segher Boessenkool <seg...@kernel.crashing.org> PR target/103624 * config/rs6000/rs6000-builtins.def (__builtin_darn): Expand to darn_64_di.
