Hi,
here is a simple stupid question for experienced programmers:
When using the inline assembler instructions (asm), one can chose the
"intel" or "ATT" syntax. Which one is the best, more convenient?
Trying to focus on objective factors (without any ranking - you need to
decide on their weight for you):
- AT&T syntax is available on more platforms as far as I know.
- AT&T syntax is more explicit on e.g. size of operands (you sometimes
need to guess that from context with Intel syntax).
- Intel syntax may be better alternative if you need to consider
interoperability with e.g. Delphi or some other Pascal compilers on x86
platform.
- Considering that majority of Pascal programmers these days have some
background with either TP/BP, Delphi or one of their clones (and these
usually only support Intel syntax), there are probably more Pascal
programmers who understand / prefer Intel syntax.
- If specifically targetting x86 platforms, I believe that there's more
documentation available for Intel syntax too (including reference and
optimization documents directly from CPU producers).
