GCC modified for the FreeChainXenon project
06889da8cc
This patch makes expand_debug_expr track polynomial memory offsets. It simplifies the handling of the case in which the reference is not to the first byte of the base, which seemed non-trivial enough to make it worth splitting out as a separate patch. 2017-12-20 Richard Sandiford <richard.sandiford@linaro.org> Alan Hayward <alan.hayward@arm.com> David Sherwood <david.sherwood@arm.com> gcc/ * tree.h (get_inner_reference): Add a version that returns the offset and size as poly_int64_pods rather than HOST_WIDE_INTs. * cfgexpand.c (expand_debug_expr): Track polynomial offsets. Simply the case in which bitpos is not associated with the first byte. Co-Authored-By: Alan Hayward <alan.hayward@arm.com> Co-Authored-By: David Sherwood <david.sherwood@arm.com> From-SVN: r255892 |

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.
