[gcc] 2015-03-19 Michael Meissner <meissner@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. [gcc/testsuite] 2015-03-19 Michael Meissner <meissner@linux.vnet.ibm.com> PR target/65240 * gcc/testsuite/g++.dg/pr65240.h: Add tests for PR 65240. * gcc/testsuite/g++.dg/pr65240-1.C: Likewise. * gcc/testsuite/g++.dg/pr65240-2.C: Likewise. * gcc/testsuite/g++.dg/pr65240-3.C: Likewise. * gcc/testsuite/g++.dg/pr65240-4.C: Likewise.

This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
