25 | A listing page looks like: | |
26 | ||
27 | LISTING_HEADER sourcefilename pagenumber | |
28 | TITLE LINE | |
29 | SUBTITLE LINE | |
30 | linenumber address data source | |
31 | linenumber address data source | |
32 | linenumber address data source | |
33 | linenumber address data source | |
34 | ||
35 | If not overridden, the listing commands are: | |
36 | ||
37 | .title "stuff" | |
38 | Put "stuff" onto the title line | |
39 | .sbttl "stuff" | |
40 | Put stuff onto the subtitle line | |
41 | ||
5d9f0ecf SC |
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 | |
c593cf41 SC |
44 | |
45 | .eject | |
46 | Thow a page | |
47 | .list | |
48 | Increment the enable listing counter | |
49 | .nolist | |
50 | Decrement the enable listing counter | |
51 | ||
52 | .psize Y[,X] | |
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 | |
55 | ||
56 | If the counter goes below zero, listing is suppressed. | |
57 | ||
58 | ||
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. | |
64 | ||
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. | |
69 | ||
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. | |
74 | ||
75 | The only things which the architecture can change about the listing | |
76 | are defined in these macros: | |
77 | ||
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 | |
83 | 78 | |
84 | LISTING_LHS_WIDTH Number of words of above size for the lhs | |
85 | ||
86 | LISTING_LHS_WIDTH_SECOND Number of words for the data on the lhs | |
87 | for the second line | |
88 | ||
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 | |
91 | on a line | |
