When looking at the verification, I have noticed a bug in it. The verification that CASE_HIGH (if present) has the same type as CASE_LOW is only performed for the case label 2 and higher, case label 1 (the first one after the default label) isn't checked. The following patch fixes that, it will uselessly also compare TREE_TYPE (CASE_LOW (elt)) != elt_type for the case label 1, but I think that isn't that expensive and helps readability of the code. 2020-08-31 Jakub Jelinek <jakub@redhat.com> * tree-cfg.c (verify_gimple_switch): If the first non-default case label has CASE_HIGH, verify it has the same type as CASE_LOW. |

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.
