I /believe/ the problem with the 'nasm' pygments lexer (I'm using Sphinx
1.1.3, and Pygments 1.5 is that it doesn't recognize
@DATA
as a legal identifier (commenting out the line with that identifier makes
the nasm lexer pretty-print both forms, and checking the code for the nasm
lexer indicates that it requires identifiers to start with a lower or upper
alpha, dollar, period, underbar, or question mark:
identifier = r'[a-zA-Z$._?][a-zA-Z0-9$._?#@~]*'
The 'gas' lexer doesn't recognize @ as a valid initial character for an
identifier either: either an identifier must start with an alpha, dollar or
underbar (and in this case, it can be a single character), OR it must start
with a period (and in this case be followed by at least one other valid
identifier character (including the @ character).
I'm not saying that @DATA is not a legal identifier for your assembly -- I
don't know assembly. But the pygments lexers don't seem to think so...
The 'llvm' lexer does admit that @DATA could be a valid identifier, but
there could be other issues in the code there -- characterizing the blocks
as llvm code doesn't pretty-print either of them. (Actually, characterizing
them as 'gas' doesn't pretty-print either of them either.)
To test these, I used a ".. code-block:: nasm" (and so on) directive to
explicitly characterize the code. As far as I can tell (as of pygments
1.5), there are there are three assembly dialects supported: nasm, gas, and
llvm.
