This patch continues the refactoring started with r12-6014. I had previously noted that the resolve_vec* routines can be further simplified by processing the argument list earlier, so that all routines can use the arrays of arguments and types. I found that this was useful for some of the routines, but not for all of them. For several of the special-cased overloads, we don't specify all of the possible type combinations in rs6000-overload.def, because the types don't matter for the expansion we do. For these, we can't use generic error message handling when the number of arguments is incorrect, because the result is misleading error messages that indicate argument types are wrong. So this patch goes halfway and improves the factoring on the remaining special cases, but leaves vec_splats, vec_promote, vec_extract, vec_insert, and vec_step alone. 2022-02-02 Bill Schmidt <wschmidt@linux.ibm.com> gcc/ * config/rs6000/rs6000-c.cc (resolve_vec_mul): Accept args and types parameters instead of arglist and nargs. Simplify accordingly. Remove unnecessary test for argument count mismatch. (resolve_vec_cmpne): Likewise. (resolve_vec_adde_sube): Likewise. (resolve_vec_addec_subec): Likewise. (altivec_resolve_overloaded_builtin): Move overload special handling after the gathering of arguments into args[] and types[] and the test for correct number of arguments. Don't perform the test for correct number of arguments for certain special cases. Call the other special cases with args and types instead of arglist and nargs. |

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.
