@ -165,4 +165,17 @@ using `IX` and `IY` as 8-bit registers. We used to support them, but because
|
||||
this makes our code incompatible with Z80-compatible CPUs such as the Z180, we
|
||||
prefer to avoid these in our code.
|

|
||||
## AVR assembler
|
||||
|
||||
`zasm` can be configured, at compile time, to be a AVR assembler instead of a
|
||||
z80 assembler. Directives, literals, symbols, they're all the same, it's just
|
||||
instructions and their arguments that change.
|
||||
|
||||
Instructions and their arguments have a ayntax that is similar to other AVR
|
||||
assemblers: registers are referred to as `rXX`, mnemonics are the same,
|
||||
arguments are separated by commas.
|
||||
|
||||
To assemble an AVR assembler, use the `gluea.asm` file instead of the regular
|
||||
one.

The AVR instruction set is a bit more regular than z80's, which allows us for
|
||||
simpler upcode spitting logic (simplicity which is lost when we need to take
|
||||
into account all AVR models and instruction constraints on each models). This
|
||||
file categorizes all available ops with their opcode signature. X means upcode
|

bit.
|

Categories are in descending order of "popularity"
|

Mnemonics with "*" are a bit special.
