| 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 | |
| 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 |
