In order to stress test RAW_DATA_CST handling, I've tested trunk gcc with r15-6339 reapplied and a hack where I've changed const unsigned int raw_data_min_len = 128; to const unsigned int raw_data_min_len = 2; in cp_lexer_new_main and 64 to 4 several times in c_parser_initval and c_maybe_optimize_large_byte_initializer, so that RAW_DATA_CST doesn't trigger just on very large initializers, but even quite small ones. One of the regressions (will work on the others next) was that pr90838.c testcase regressed, check_ctz_array needs to handle RAW_DATA_CST, otherwise on larger initializers or if those come from #embed just won't trigger. The new testcase shows when it doesn't trigger anymore (regression from 14). The patch just handles RAW_DATA_CST in the CONSTRUCTOR_ELTS the same as is it was a series of INTEGER_CSTs. 2025-01-02 Jakub Jelinek <jakub@redhat.com> * tree-ssa-forwprop.cc (check_ctz_array): Handle also RAW_DATA_CST in the CONSTRUCTOR_ELTS. * gcc.dg/pr90838-2.c: New test. |

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.
