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