@ -165,17 +165,4 @@ 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.

simpler upcode spitting logic (simplicity which is lost when we need to take
