standard.h

// ****************************************************************************
// Prelude, this file is used with -macro_file_builtins option of the C parser
// ****************************************************************************

/* This file contains:
 *   - macros found in <.h>
 *   - macros found in ".h"
 *     but where we cannot detect that it will be a "bad macro"
 *   - hints, cf below.
 *
 * A "bad macro" is a macro using free variables or when expanded
 * that influence the control-flow of the code. In those cases it
 * is preferable to expand the macro so that the coccinelle engine
 * has a more accurate representation of what is going on.
 *
 *
 *
 *
 * old: this file was also containing what is below but now we
 * try to expand on demand the macro found in the c file, so those cases
 * are not needed any more:
 *   - macros found in .c; macros that cannot be parsed.
 *     In the future should be autodetected
 *     (not so easy to do same for macros in .h cos require to access .h file)
 *   - macros found in .c; macros correctly parsed
 *     but where we cannot detect that it will be a "bad macro"
 *
 * Some of those macros could be deleted and the C code rewritten because
 * they are "bad" macros.
 *
 * todo? perhaps better if could enable/disable some of those expansions
 * as different software may use conflicting macros.
 *
 *
 * can maybe have a look in sparse/lib.c to see a list of default #define
 * handled builtin apparently by gcc.
 */

// ****************************************************************************
// Hints
// ****************************************************************************

/* Cooperation with parsing_hack.ml: some body of macros in this file, such
 * as MACROSTATEMENT, are considered as magic strings.
 * I can't just expand those macros into some 'whatever();' because I need
 * to generate a TMacroStmt for solving some ambiguities in the grammar
 * for the toplevel stuff I think.
 * Right now a set of special strings are used as "hints" to the parser
 * to help it parse code. Those hints are specified in parsing_hack.ml:
 *
 *   - YACFE_ITERATOR
 *   - YACFE_DECLARATOR
 *   - YACFE_STRING
 *   - YACFE_STATEMENT, or MACROSTATEMENT
 *   - YACFE_ATTRIBUTE
 *   - YACFE_IDENT_BUILDER

 *
 * cf include/linux/kernel.h

 * be transformed in a typedef later, so better to at least
 * transform in string already the string-macro we know.
 *
 * Perhaps better to apply also as soon as possible the
