26 A listing page looks like:
28 LISTING_HEADER sourcefilename pagenumber
31 linenumber address data source
32 linenumber address data source
33 linenumber address data source
34 linenumber address data source
36 If not overridden, the listing commands are:
39 Put "stuff" onto the title line
41 Put stuff onto the subtitle line
43 If these commands come within 10 lines of the top of the page, they
44 will affect the page they are on, as well as any subsequent page
49 Increment the enable listing counter
51 Decrement the enable listing counter
54 Set the paper size to X wide and Y high. Setting a psize Y of
55 zero will suppress form feeds except where demanded by .eject
57 If the counter goes below zero, listing is suppressed.
59 Listings are a maintained by read calling various listing_<foo>
60 functions. What happens most is that the macro NO_LISTING is not
61 defined (from the Makefile), then the macro LISTING_NEWLINE expands
62 into a call to listing_newline. The call is done from read.c, every
63 time it sees a newline, and -l is on the command line.
65 The function listing_newline remembers the frag associated with the
66 newline, and creates a new frag - note that this is wasteful, but not
67 a big deal, since listing slows things down a lot anyway. The
68 function also rememebers when the filename changes.
70 When all the input has finished, and gas has had a chance to settle
71 down, the listing is output. This is done by running down the list of
72 frag/source file records, and opening the files as needed and printing
73 out the bytes and chars associated with them.
75 The only things which the architecture can change about the listing
76 are defined in these macros:
78 LISTING_HEADER The name of the architecture
79 LISTING_WORD_SIZE The make of the number of bytes in a word, this determines
80 the clumping of the output data. eg a value of
81 2 makes words look like 1234 5678, whilst 1
82 would make the same value look like 12 34 56
84 LISTING_LHS_WIDTH Number of words of above size for the lhs
86 LISTING_LHS_WIDTH_SECOND Number of words for the data on the lhs
89 LISTING_LHS_CONT_LINES Max number of lines to use up for a continutation
90 LISTING_RHS_WIDTH Number of chars from the input file to print
