longDescription = ''
|
|
xa is a high-speed, two-pass portable cross-assembler. It understands
|
|
mnemonics and generates code for NMOS 6502s (such as 6502A, 6504, 6507,
|
|
6510, 7501, 8500, 8501, 8502 ...), CMOS 6502s (65C02 and Rockwell R65C02)
|
|
and the 65816.
|
|
|
|
Key amongst its features:
|
|
|
|
- C-like preprocessor (and understands cpp for additional feature support)
|
|
- rich expression syntax and pseudo-op vocabulary
|
|
- multiple character sets
|
|
- binary linking
|
|
- supports o65 relocatable objects with a full linker and relocation
|
|
suite, as well as "bare" plain binary object files
|
|
- block structure for label scoping
