Setting a psize Y of - zero will suppress form feeds except where demanded by .eject - - If the counter goes below zero, listing is suppressed. - - Listings are a maintained by read calling various listing_<foo> - functions. What happens most is that the macro NO_LISTING is not - defined (from the Makefile), then the macro LISTING_NEWLINE expands - into a call to listing_newline. The call is done from read.c, every - time it sees a newline, and -l is on the command line. - - The function listing_newline remembers the frag associated with the - newline, and creates a new frag - note that this is wasteful, but not - a big deal, since listing slows things down a lot anyway. The - function also remembers when the filename changes. - - When all the input has finished, and gas has had a chance to settle - down, the listing is output. This is done by running down the list of - frag/source file records, and opening the files as needed and printing - out the bytes and chars associated with them. - - The only things which the architecture can change about the listing - are defined in these macros: - - LISTING_HEADER The name of the architecture - LISTING_WORD_SIZE The make of the number of bytes in a word, this determines - the clumping of the output data. eg a value of - 2 makes words look like 1234 5678, whilst 1 - would make the same value look like 12 34 56 - 78 - LISTING_LHS_WIDTH Number of words of above size for the lhs - - LISTING_LHS_WIDTH_SECOND Number of words for the data on the lhs - for the second line - - LISTING_LHS_CONT_LINES Max number of lines to use up for a continuation - LISTING_RHS_WIDTH Number of chars from the input file to print - on a line. */ - -#include "as.h" -#include "obstack.h" -#include "safe-ctype.h" -#include "input-file.h" -#include "subsegs.h" - -#ifndef NO_LISTING - -#ifndef LISTING_HEADER -#define LISTING_HEADER "GAS LISTING" -#endif -#ifndef LISTING_WORD_SIZE -#define LISTING_WORD_SIZE 4 -#endif -#ifndef LISTING_LHS_WIDTH -#define LISTING_LHS_WIDTH ((LISTING_WORD_SIZE) > 4 ? 1 : 4 / (LISTING_WORD_SIZE)) -#endif -#ifndef LISTING_LHS_WIDTH_SECOND -#define LISTING_LHS_WIDTH_SECOND LISTING_LHS_WIDTH -#endif -#ifndef LISTING_RHS_WIDTH -#define LISTING_RHS_WIDTH 100 -#endif -#ifndef LISTING_LHS_CONT_LINES -#define LISTING_LHS_CONT_LINES 4 -#endif - -/* This structure remembers which .s were used. */ -typedef struct file_info_struct -{ - struct file_info_struct * next; - char * filename; - long pos; - unsigned int linenum; - int at_end; -} file_info_type; - -/* This structure remembers which line from which file goes into which - frag. */ -struct list_info_struct -{ - /* Frag which this line of source is nearest to. */ - fragS *frag; - - /* The actual line in the source file. */ - unsigned int line; - - /* Pointer to the file info struct for the file which this line - belongs to. */ - file_info_type *file; - - /* The expanded text of any macro that may have been executing. */ - char *line_contents; - - /* Next in list. */ - struct list_info_struct *next; - - /* Pointer to the file info struct for the high level language - source line that belongs here. */ - file_info_type *hll_file; - - /* High level language source line. */ - unsigned int hll_line; - - /* Pointer to any error message associated with this line. */ - char *message; - - enum - { - EDICT_NONE, - EDICT_SBTTL, - EDICT_TITLE, - EDICT_NOLIST, - EDICT_LIST, - EDICT_NOLIST_NEXT, - EDICT_EJECT - } edict; - char *edict_arg; - - /* Nonzero if this line is to be omitted because it contains - debugging information.
