(vectorizable_type_promotion): Support loop-aware SLP and general multi-step conversion. Call vect_create_vectorized_promotion_stmts for transformation. (vectorizable_store): Change documentation, support multiple types in SLP. (vectorizable_load): Likewise. (vect_transform_stmt): Pass SLP_NODE to vectorizable_type_promotion and vectorizable_type_demotion. (vect_schedule_slp_instance): Move here the calculation of number of vectorized statements for each node from... (vect_schedule_slp): ... here. (vect_transform_loop): Call vect_schedule_slp without the last argument. From-SVN: r139225 |

This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the file 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.html for how to report bugs usefully.
