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
|
