Looks like my patch for PR analyzer/99212 implicitly assumed little-endian, which the following patch fixes. Fixes bitfields-1.c on: - armeb-none-linux-gnueabihf - cris-elf - powerpc64-darwin - s390-linux-gnu gcc/analyzer/ChangeLog: PR analyzer/99212 PR analyzer/101082 * engine.cc: Include "target.h". (impl_run_checkers): Log BITS_BIG_ENDIAN, BYTES_BIG_ENDIAN, and WORDS_BIG_ENDIAN. * region-model-manager.cc (region_model_manager::maybe_fold_binop): Move support for masking via ARG0 & CST into... (region_model_manager::maybe_undo_optimize_bit_field_compare): ...this new function. Flatten by converting from nested conditionals to a series of early return statements to reject failures. Reject if type is not unsigned_char_type_node. Handle BYTES_BIG_ENDIAN when determining which bits are bound in the binding_map. * region-model.h (region_model_manager::maybe_undo_optimize_bit_field_compare): New decl. * store.cc (bit_range::dump): New function. * store.h (bit_range::dump): New decl.

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.
