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