--- Comment #15 from Peter Bergner <bergner at gcc dot gnu.org> --- Author: bergner Date: Mon May 12 23:08:22 2014 New Revision: 210344 URL: http://gcc.gnu.org/viewcvs?rev=210344&root=gcc&view=rev Log: Reapply the old IBM 4.8 branch patches that are not upstream. gcc/ Back port mainline subversion id 209025. 2014-04-02 Michael Meissner <meiss...@linux.vnet.ibm.com> PR target/60735 * config/rs6000/rs6000.c (rs6000_hard_regno_mode_ok): If we have software floating point or no floating point registers, do not allow any type in the FPRs. Eliminate a test for SPE SIMD types in GPRs that occurs after we tested for GPRs that would never be true. Back port from main line: 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.c (rs6000_debug_reg_global): If -mdebug=reg, print value of VECTOR_ELEMENT_SCALAR_64BIT. * config/rs6000/rs6000.h (VECTOR_ELEMENT_SCALAR_64BIT): Macro to define the top 64-bit vector element. * 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. * doc/md.texi (PowerPC and IBM RS6000 constraints): Document wD constraint. * 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. Backport from mainline 2013-08-01 Fabien Chêne <fab...@gcc.gnu.org> PR c++/54537 * include/tr1/cmath: Remove pow(double,double) overload, remove a duplicated comment about DR 550. Add a comment to explain the issue. * testsuite/tr1/8_c_compatibility/cmath/pow_cmath.cc: New. gcc/testsuite/ Back port from mainline 2013-08-01 Fabien Chêne <fab...@gcc.gnu.org> Peter Bergner <berg...@vnet.ibm.com> PR c++/54537 * g++.dg/overload/using3.C: New. * g++.dg/overload/using2.C: Adjust. * g++.dg/lookup/using9.C: Likewise. gcc/cp/ Back port from mainline 2013-08-01 Fabien Chêne <fab...@gcc.gnu.org> PR c++/54537 * cp-tree.h: Check OVL_USED with OVERLOAD_CHECK. * name-lookup.c (do_nonmember_using_decl): Make sure we have an OVERLOAD before calling OVL_USED. Call diagnose_name_conflict instead of issuing an error without mentioning the conflicting declaration. libgcc/ * config/rs6000/ibm-ldouble.c (pack_ldouble): New function. (__gcc_qadd): Use it. (__gcc_qmul): Likewise. (__gcc_qdiv): Likewise. (__gcc_qneg): Likewise. (__gcc_stoq): Likewise. (__gcc_dtoq): Likewise.
