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 | ||
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 | |
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 | 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. | |
63 | ||
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 | |
47eebc20 | 67 | function also remembers when the filename changes. |
252b5132 RH |
68 | |
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. | |
73 | ||
74 | The only things which the architecture can change about the listing | |
75 | are defined in these macros: | |
76 | ||
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 | |
82 | 78 | |
83 | LISTING_LHS_WIDTH Number of words of above size for the lhs | |
84 | ||
85 | LISTING_LHS_WIDTH_SECOND Number of words for the data on the lhs | |
86 | for the second line | |
87 | ||
47eebc20 | 88 | LISTING_LHS_CONT_LINES Max number of lines to use up for a continuation |
252b5132 | 89 | LISTING_RHS_WIDTH Number of chars from the input file to print |
5a1964ec | 90 | on a line. */ |
