--- Comment #3 from Michael Meissner <meissner at gcc dot gnu.org> --- Author: meissner Date: Tue Oct 6 17:20:49 2015 New Revision: 228538 URL: https://gcc.gnu.org/viewcvs?rev=228538&root=gcc&view=rev Log: [gcc] 2015-10-05 Michael Meissner <meiss...@linux.vnet.ibm.com> Peter Bergner <berg...@vnet.ibm.com> PR target/67808 * config/rs6000/rs6000.md (extenddftf2): In the expander, only allow registers, but provide insns for the combiner to create for loads from memory. Separate VSX code from non-VSX code. For non-VSX code, combine extenddftf2_fprs into extenddftf2 and rename externaldftf2_internal to externaldftf2_fprs. Reorder constraints so that registers come before memory operations. Drop support from converting DFmode to TFmode, if the DFmode value is in a GPR register. (extenddftf2_fprs): Likewise. (extenddftf2_internal): Likewise. (extenddftf2_vsx): Likewise. (extendsftf2): In the expander, only allow registers, but provide insns for the combiner to create for stores and loads.
