--- Comment #2 from Segher Boessenkool <segher at gcc dot gnu.org> --- Author: segher Date: Sat Apr 14 21:13:20 2018 New Revision: 259386 URL: https://gcc.gnu.org/viewcvs?rev=259386&root=gcc&view=rev Log: rs6000: Disable -m[no-]direct-move (PR85293) The -mno-direct-move option causes a lot of problems, since it forces us to be able to generate code for p8 and up with some crucial instructions missing. This patch removes the -m[no-]direct-move options so that the user cannot put us into this unexpected situation anymore. Internally we still have all the same flags, and they are automatically set based on -mcpu; getting rid of that is a lot more work and will have to wait for GCC 9 (in some places the flag is used to see if we are compiling for a p8 _at all_). PR target/85293 * config/rs6000/rs6000.opt (mdirect-move): Make deprecated. * doc/invoke.texi (RS/6000 and PowerPC Options): Remove -mdirect-move and -mno-direct-move. gcc/testsuite/ PR target/85293 * gcc.target/powerpc/pr80098-2.c: Remove -mdirect-move. Remove the corresponding dg-error clause. * gcc.target/powerpc/pr80098-3.c: Ditto. * gcc.target/powerpc/pr80103-1.c: Delete.
