GCC modified for the FreeChainXenon project

The ZTYPE in iso modula2 is used to denote intemediate ordinal type const expressions and these are always converted into the approriate language or user ordinal type prior to code generation. The increase of bits supported by _BitInt causes the modula2 largeconst.mod regression failure tests to pass. The largeconst.mod test has been increased to fail, however the char at a time overflow check is now too slow to detect failure. The overflow detection for the ZTYPE has been rewritten to check against exceeding WIDE_INT_MAX_PRECISION (many orders of magnitude faster). gcc/m2/ChangeLog: PR modula2/102989 * gm2-compiler/SymbolTable.mod (OverflowZType): Import from m2expr. (ConstantStringExceedsZType): Remove import. (GetConstLitType): Replace ConstantStringExceedsZType with OverflowZType. * gm2-gcc/m2decl.cc (m2decl_ConstantStringExceedsZType): Remove. (m2decl_BuildConstLiteralNumber): Re-write. * gm2-gcc/m2decl.def (ConstantStringExceedsZType): Remove. * gm2-gcc/m2decl.h (m2decl_ConstantStringExceedsZType): Remove. * gm2-gcc/m2expr.cc (m2expr_StrToWideInt): Rewrite to check overflow. (m2expr_OverflowZType): New function. (ToWideInt): New function. * gm2-gcc/m2expr.def (OverflowZType): New procedure function declaration. * gm2-gcc/m2expr.h (m2expr_OverflowZType): New prototype. gcc/testsuite/ChangeLog: PR modula2/102989 * gm2/pim/fail/largeconst.mod: Updated foo to an outrageous value. * gm2/pim/fail/largeconst2.mod: Duplicate test removed.

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.
