Machines that had CLEAR_CACHE_INSN and that would thus issue calls to __clear_cache with the default call expander, would fail on languages that did not set up the __clear_cache builtin. This patch arranges for all languages to set up this builtin. Machines or multilibs that had ptr_mode != Pmode, such as aarch64 with -mabi=ilp32, would fail the RTL mode test of the arguments passed to __clear_cache, because we'd insist on ptr_mode. This patch arranges for Pmode to be accepted as well. for gcc/ChangeLog * tree.c (build_common_builtin_nodes): Declare __builtin___clear_cache for all languages. * builtins.c (maybe_emit_call_builtin___clear_cache): Accept Pmode arguments.
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.
