This patch recognizes case of dynamic predicates on integer subtypes that are simple enough to be evaluated statically when the argument is itself a literal. Even though in many cases such predicate checks will be removed by the back-end with any level of optimization, it is preferable to perform this constant folding in the front-end, wich also cleans up the output of CCG, as well as producing explicit warnings when the test will fail. 2019-07-11 Ed Schonberg <schonberg@adacore.com> gcc/ada/ * exp_ch6.adb (Can_Fold_Predicate_Call): New function, subsidiary of Expand_Call_Helper, to compute statically a predicate check when the argument is a static integer. gcc/testsuite/ * gnat.dg/predicate11.adb: New testcase.

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.
