Improve code generation for edge and pixel-compare, specifically avoid sign and zero extensions on 64-bit and allow such instructions to be placed in delay slots. gcc/ * config/sparc/sparc.md (edge{8,16,32}{,l}): Return Pmode. (fcmp{le,ne,gt,eq}{16,32}): Likewise. * config/sparc/visintrin.h: Update edge and pixel-compare intrinsics to return 'long' instead of 'int'. * doc/extend.texi: Update documentation to match. * config/sparc/sparc.c (eligible_for_return_delay): When leaf or flat, allow any instruction. Otherwise, when V9 allow parallels which consist only of sets to registers outside of %o0 to %o5. (sparc_vis_init_builtins): Update VIS builtin types for edge and pixel-compare. gcc/testsuite/ * gcc.target/sparc/edge.c: Update for new return types. * gcc.target/sparc/fcmp.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.
