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
