This is because the * trailing context must be considered as well. * * The only certain assumption for the preprocessor to make is that * directives start at the beginning of the line, followed by a '#' * and end with a newline. * Any directive may be suffixed with a line-continuation. Also * classical comment / *...* / (note: no comments within comments, * therefore spaces) is considered to be a line-continuation * (according to gcc and egcs AFAIK, ANSI is a bit vague). * Comments have not been added to the above grammer for simplicity * reasons. However, it is allowed to enter comment anywhere within * the directives as long as they do not interfere with the context. * All comments are considered to be deletable whitespace (both * classical form "/ *...* /" and C++ form "//...\n"). * * All recursive scans, except for macro-expansion, are done by the * parser, whereas the simple state transitions of non-recursive * directives are done in the scanner. This results in the many * exclusive start-conditions of the scanner. * * Macro expansions are slightly more difficult because they have to * prescan the arguments. Parameter substitution is literal if the * substitution is # or ## (either side). This enables new identifiers * to be created (see 'info cpp' node Macro|Pitfalls|Prescan for more * information). * * FIXME: Variable macro parameters is recognized, but not yet * expanded. I have to reread the ANSI standard on the subject (yes, * ANSI defines it). * * The following special defines are supported: * __FILE__ -> "thissource.c" * __LINE__ -> 123 * __DATE__ -> "May 1 2000" * __TIME__ -> "23:59:59" * These macros expand, as expected, into their ANSI defined values. * * The same include prevention is implemented as gcc and egcs does. * This results in faster processing because we do not read the text * at all. Some wine-sources attempt to include the same file 4 or 5 * times. This strategy also saves a lot blank output-lines, which in * its turn improves the real resource scanner/parser. * */ /* * Special flex options and exclusive scanner start-conditions */ #define YY_STACK_USED 1 #define YY_NEVER_INTERACTIVE 1 #define pp_pp 1 #define pp_eol 2 #define pp_inc 3 #define pp_dqs 4 #define pp_sqs 5 #define pp_iqs 6 #define pp_comment 7 #define pp_def 8 #define pp_define 9 #define pp_macro 10 #define pp_mbody 11 #define pp_macign 12 #define pp_macscan 13 #define pp_macexp 14 #define pp_if 15 #define pp_ifd 16 #define pp_line 17 #define pp_defined 18 #define pp_ignore 19 #line 140 "ppl.l" #include "config.h" #include #include #include #include #include #include "utils.h" #include "wrc.h" #include "preproc.h" #include "ppy.tab.h" /* * Make sure that we are running an appropriate version of flex. */ #if !defined(YY_FLEX_MAJOR_VERSION) || (1000 * YY_FLEX_MAJOR_VERSION + YY_FLEX_MINOR_VERSION < 2005) #error Must use flex version 2.5.1 or higher (yy_scan_* routines are required). #endif #define YY_USE_PROTOS #define YY_NO_UNPUT #define YY_READ_BUF_SIZE 65536 /* So we read most of a file at once */ #define yy_current_state() YY_START #define yy_pp_state(x) yy_pop_state(); yy_push_state(x) /* * Always update the current character position within a line */ #define YY_USER_ACTION char_number+=ppleng; /* * Buffer management for includes and expansions */ #define MAXBUFFERSTACK 128 /* Nesting more than 128 includes or macro expansion textss is insane */ typedef struct bufferstackentry { YY_BUFFER_STATE bufferstate; /* Buffer to switch back to */ pp_entry_t *define; /* Points to expanding define or NULL if handling includes */ int line_number; /* Line that we were handling */ int char_number; /* The current position on that line */ char *filename; /* Filename that we were handling */ int if_depth; /* How many #if:s deep to check matching #endif:s */ int ncontinuations; /* Remember the continuation state */ int should_pop; /* Set if we must pop the start-state on EOF */ /* Include management */ int include_state; char *include_ppp; char *include_filename; int include_ifdepth; int seen_junk; } bufferstackentry_t; #define ALLOCBLOCKSIZE (1 << 10) /* Allocate these chunks at a time for string-buffers */ /* * Macro expansion nesting * We need the stack to handle expansions while scanning * a macro's arguments.
