--- Comment #1 from Michael Meissner <meissner at gcc dot gnu.org> --- Author: meissner Date: Thu Mar 27 20:07:16 2014 New Revision: 208877 URL: http://gcc.gnu.org/viewcvs?rev=208877&root=gcc&view=rev Log: [gcc] 2014-03-27 Michael Meissner <meiss...@linux.vnet.ibm.com> * config/rs6000/constraints.md (wD constraint): New constraint to match the constant integer to get the top DImode/DFmode out of a vector in a VSX register. * config/rs6000/predicates.md (vsx_scalar_64bit): New predicate to match the constant integer to get the top DImode/DFmode out of a vector in a VSX register. * config/rs6000/rs6000-builtins.def (VBPERMQ): Add vbpermq builtin for ISA 2.07. * config/rs6000/rs6000-c.c (altivec_overloaded_builtins): Add vbpermq builtins. * config/rs6000/rs6000.c (rs6000_debug_reg_global): If -mdebug=reg, print value of VECTOR_ELEMENT_SCALAR_64BIT. * config/rs6000/vsx.md (vsx_extract_<mode>, V2DI/V2DF modes): Optimize vec_extract of 64-bit values, where the value being extracted is in the top word, where we can use scalar instructions. Add direct move and store support. Combine the big endian/little endian vector select load support into a single insn. (vsx_extract_<mode>_internal1): Likewise. (vsx_extract_<mode>_internal2): Likewise. (vsx_extract_<mode>_load): Likewise. (vsx_extract_<mode>_store): Likewise. (vsx_extract_<mode>_zero): Delete, big and little endian insns are combined into vsx_extract_<mode>_load. (vsx_extract_<mode>_one_le): Likewise. * config/rs6000/rs6000.h (VECTOR_ELEMENT_SCALAR_64BIT): Macro to define the top 64-bit vector element. * doc/md.texi (PowerPC and IBM RS6000 constraints): Document wD constraint. PR target/60672 * config/rs6000/altivec.h (vec_xxsldwi): Add missing define to enable use of xxsldwi and xxpermdi builtin functions. (vec_xxpermdi): Likewise. * doc/extend.texi (PowerPC AltiVec/VSX Built-in Functions): Document use of vec_xxsldwi and vec_xxpermdi builtins. [gcc/testsuite] 2014-03-27 Michael Meissner <meiss...@linux.vnet.ibm.com> * gcc.target/powerpc/p8vector-vbpermq.c: New test to test the vbpermq builtin. * gcc.target/powerpc/vsx-extract-1.c: New test to test VSX vec_select optimizations. * gcc.target/powerpc/vsx-extract-2.c: Likewise. * gcc.target/powerpc/vsx-extract-3.c: Likewise. PR target/60672 * gcc.target/powerpc/pr60676.c: New file, make sure xxsldwi and xxpermdi builtins are supported.
