* 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. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@53152 138bc75d-0d04-0410-961f-82ee72b054a4
