GCC modified for the FreeChainXenon project
e781cb93d7
This PR shows that I didn't properly test the multi-vector case when adding support for SLP gather loads. The patch fixes that case using the same approach as we do for non-SLP cases: keep the scalar base the same, but iterate through the (also multi-vector) vector offsets. “vec_num * j + i” is already used elsewhere as a way of handling both the multi-vector SLP case and the multi-vector non-SLP case. gcc/ PR tree-optimization/103744 * tree-vect-stmts.c (vectorizable_load): Handle multi-vector SLP gather loads. gcc/testsuite/ PR tree-optimization/103744 * gcc.dg/vect/pr103744-1.c: New test. * gcc.dg/vect/pr103744-2.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.
