* cselib.c (promote_debug_loc): Allow l->next non-NULL for cselib_preserve_constants. (cselib_lookup_1): If cselib_preserve_constants, a new VALUE is being created for REG and there is a VALUE for the same register in wider mode, add another loc with lowpart SUBREG of the wider VALUE. (cselib_subst_to_values): Handle ENTRY_VALUE. * var-tracking.c (replace_expr_with_values): Return NULL for ENTRY_VALUE too. * dwarf2out.c (convert_descriptor_to_signed): New function. (mem_loc_descriptor) <case ZERO_EXTEND>: Optimize using DW_OP_and instead of two shifts. (mem_loc_descriptor) <do_shift>: ZERO_EXTEND second argument to the right mode if needed. (mem_loc_descriptor) <case MOD>: For typed ops just use DW_OP_mod. (mem_loc_descriptor) <case UNSIGNED_FIX>: Use convert_descriptor_to_signed. (mem_loc_descriptor) <case UDIV, CLZ, CTZ, FFS, POPCOUNT, PARITY, BSWAP, ROTATE, ROTATERT>: Handle these rtls. * gcc.dg/guality/bswaptest.c: New test. * gcc.dg/guality/clztest.c: New test. * gcc.dg/guality/ctztest.c: New test. * gcc.dg/guality/rotatetest.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.
