29 ** Yacc/Bison grammar for extended ANSI C used by Splint.
31 ** original grammar by Nate Osgood ---
32 ** hacrat@catfish.lcs.mit.edu Mon Jun 14 13:06:32 1993
34 ** changes for Splint --- handle typedef names correctly
35 ** fix struct/union parsing bug (empty struct is accepted)
36 ** add productions to handle macros --- require
37 ** error correction --- main source of conflicts in grammar.
38 ** need to process initializations sequentially, L->R
40 ** production names are cryptic, so more productions fit on one line
42 ** conflicts: 87 shift/reduce, 18 reduce/reduce
43 ** most of these are due to handling macros
44 ** a few are due to handling type expressions
50 extern void yyerror (char *);
52 # include "splintMacros.nf"
54 # include "cscanner.h"
55 # include "cgrammar.h"
56 # include "exprChecks.h"
61 # define SHOWCSYM FALSE
64 ** This is necessary, or else when the bison-generated code #include's malloc.h,
65 ** there will be a parse error.
67 ** Unfortunately, it means the error checking on malloc, etc. is lost for allocations
68 ** in bison-generated files under Win32.
