A listing page looks like:
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
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.
+ function also remembers 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
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_LHS_CONT_LINES Max number of lines to use up for a continuation
LISTING_RHS_WIDTH Number of chars from the input file to print
