* c-lex.c (lex_string): Let cpp_parse_escape handles truncation and sign-extension. (lex_charconst): Update for change in prototype of cpp_interpret_charconst. Extend from cppchar_t to HOST_WIDE_INT appropriately. * cpphash.h (BITS_PER_CPPCHAR_T): New. * cppinit.c (cpp_create_reader): Initialize them for no change in semantics. (cpp_post_options): Add sanity checks. * cpplex.c (cpp_parse_escape): Handle precision, sign-extension and truncation issues. Calculate in type cppchar_t. (MAX_CHAR_TYPE_SIZE, MAX_WCHAR_TYPE_SIZE): Remove. (cpp_interpret_charconst): Calculate in type cppchar_t. Handle run-time dependent precision correctly. Return whether the result is signed or not. * cpplib.c (dequote_string): Use cppchar_t; update. * cpplib.h (cppchar_signed_t): New. struct cpp_options): New precision members. (cpp_interpret_charconst, cpp_parse_escape): Update prototypes. From-SVN: r53152 |

This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the file 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.html for how to report bugs usefully.
