when callers and callees do not quite agree on the type of a parameter, usually with ill-defined K&R or with smilarly wrong LTO input, IPA-CP can attempt to try and substitute a wrong type for a parameter (see e.g. gcc.dg/torture/pr48063.c). Function tree_function_versioning attempts to handle this in order not to create invalid gimple but it then creates the mapping using setup_one_parameter which also handles the same situation to avoid similar problems when inlining and in more defined way. So this patch simply removes the conversion attempts in tree_function_versioning itself. It is helpful for my upcoming fix of PR 93385 because then I do not need to teach ipa_param_body_adjustments to distinguish between successful and unsuccessful mappings - setup_one_parameter uses force_value_to_type for conversions which simly maps the worst cases to zero. 2020-05-04 Martin Jambor <mjambor@suse.cz> PR ipa/93385 * tree-inline.c (tree_function_versioning): Leave any type conversion of replacements to setup_one_parameter and its friend force_value_to_type.

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.
