23 | A listing page looks like: | |
24 | ||
25 | LISTING_HEADER sourcefilename pagenumber | |
26 | TITLE LINE | |
27 | SUBTITLE LINE | |
28 | linenumber address data source | |
29 | linenumber address data source | |
30 | linenumber address data source | |
31 | linenumber address data source | |
32 | ||
33 | If not overridden, the listing commands are: | |
34 | ||
35 | .title "stuff" | |
36 | Put "stuff" onto the title line | |
37 | .sbttl "stuff" | |
38 | Put stuff onto the subtitle line | |
39 | ||
40 | If these commands come within 10 lines of the top of the page, they | |
41 | will affect the page they are on, as well as any subsequent page | |
42 | ||
43 | .eject | |
33eaf5de | 44 | Throw a page |
252b5132 RH |
45 | .list |
46 | Increment the enable listing counter | |
47 | .nolist | |
48 | Decrement the enable listing counter | |
49 | ||
50 | .psize Y[,X] | |
51 | Set the paper size to X wide and Y high. Setting a psize Y of | |
52 | zero will suppress form feeds except where demanded by .eject | |
53 | ||
54 | If the counter goes below zero, listing is suppressed. | |
55 | ||
252b5132 RH |
56 | Listings are a maintained by read calling various listing_<foo> |
57 | functions. What happens most is that the macro NO_LISTING is not | |
58 | defined (from the Makefile), then the macro LISTING_NEWLINE expands | |
59 | into a call to listing_newline. The call is done from read.c, every | |
60 | time it sees a newline, and -l is on the command line. | |
61 | ||
62 | The function listing_newline remembers the frag associated with the | |
63 | newline, and creates a new frag - note that this is wasteful, but not | |
64 | a big deal, since listing slows things down a lot anyway. The | |
47eebc20 | 65 | function also remembers when the filename changes. |
252b5132 RH |
66 | |
67 | When all the input has finished, and gas has had a chance to settle | |
68 | down, the listing is output. This is done by running down the list of | |
69 | frag/source file records, and opening the files as needed and printing | |
70 | out the bytes and chars associated with them. | |
71 | ||
72 | The only things which the architecture can change about the listing | |
73 | are defined in these macros: | |
74 | ||
75 | LISTING_HEADER The name of the architecture | |
76 | LISTING_WORD_SIZE The make of the number of bytes in a word, this determines | |
77 | the clumping of the output data. eg a value of | |
78 | 2 makes words look like 1234 5678, whilst 1 | |
79 | would make the same value look like 12 34 56 | |
80 | 78 | |
81 | LISTING_LHS_WIDTH Number of words of above size for the lhs | |
82 | ||
83 | LISTING_LHS_WIDTH_SECOND Number of words for the data on the lhs | |
84 | for the second line | |
85 | ||
47eebc20 | 86 | LISTING_LHS_CONT_LINES Max number of lines to use up for a continuation |
252b5132 | 87 | LISTING_RHS_WIDTH Number of chars from the input file to print |
5a1964ec | 88 | on a line. */ |
