--- Comment #15 from Michael Meissner <meissner at gcc dot gnu.org> --- Author: meissner Date: Thu Mar 19 22:37:33 2015 New Revision: 221524 URL: https://gcc.gnu.org/viewcvs?rev=221524&root=gcc&view=rev Log: [gcc] 2015-03-19 Michael Meissner <meiss...@linux.vnet.ibm.com> PR target/65240 * config/rs6000/predicates.md (easy_fp_constant): Remove special -ffast-math handling that kept non-0 constants live in the RTL until reload. Remove logic testing the number of instructions it took to create a constant in a GPR that was never used, due to a test for soft-float earlier. (memory_fp_constant): Delete, no longer used. * config/rs6000/rs6000.md (mov<MODE>_hardfloat): Remove alternatives for loading non-0 constants into GPRs for hard floating point that is no longer needed due to changes in easy_fp_constant. Add support for loading 0.0 into GPRs. (mov<mode>_hardfloat32): Likewise. (mov<mode>_hardfloat64): Likewise. (mov<mode>_64bit_dm): Likewise. (movtd_64bit_nodm): Likewise. (pre-reload move FP constant define_split): Delete define_split, since it is no longer used. (extenddftf2_internal): Remove GHF constraints that are not valid for extenddftf2.
