* config/i386/i386.c (ix86_expand_vec_perm): In merge_two use mode SUBREG of operands[0] as target. (valid_perm_using_mode_p): Don't ignore higher bits of d->perm. (expand_vec_pshufb): For V8SImode vmode emit avx2_permvarv8si. (expand_vec_perm_1): Handle identity and some broadcast permutations. (expand_vec_perm_interleave2): Handle also 32-byte modes, using vperm2[fi]128 or vpunpck[lh]* followed by single insn permutation. For d->testing_p return true earlier to avoid creating more GC garbage. (expand_vec_perm_vpermq_perm_1): New function. (expand_vec_perm_vpshufb2_vpermq): For d->testing_p return true earlier to avoid creating more GC garbage. Fix handling of V16HImode. Avoid some SUBREGs in SET_DEST. (expand_vec_perm_broadcast_1): Return false for 32-byte integer vector modes. (expand_vec_perm_vpshufb4_vpermq2): New function. (ix86_expand_vec_perm_builtin_1): Call expand_vec_perm_vpermq_perm_1 and expand_vec_perm_vpshufb4_vpermq2. From-SVN: r180169 |

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.
