This patch makes can_duplicate_and_interleave_p cope with mixtures of vector sizes, by using queries based on get_vectype_for_scalar_type instead of directly querying GET_MODE_SIZE (vinfo->vector_mode). int_mode_for_size is now the first check we do for a candidate mode, so it seemed better to restrict it to MAX_FIXED_MODE_SIZE. This avoids unnecessary work and avoids trying to create scalar types that the target might not support. 2019-11-16 Richard Sandiford <richard.sandiford@arm.com> gcc/ * tree-vectorizer.h (can_duplicate_and_interleave_p): Take an element type rather than an element mode. * tree-vect-slp.c (can_duplicate_and_interleave_p): Likewise. Use get_vectype_for_scalar_type to query the natural types for a given element type rather than basing everything on GET_MODE_SIZE (vinfo->vector_mode). Limit int_mode_for_size query to MAX_FIXED_MODE_SIZE. (duplicate_and_interleave): Update call accordingly. * tree-vect-loop.c (vectorizable_reduction): Likewise. From-SVN: r278335 |

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.
