Thanks a lot, that makes indeed sense.
The peep hole optimizer is not used for asm files shipped with sdcc, right?
So I guess I can freely decide whether I wanna use in/out (asgb style)
or ldh (rgbds/gbdk style), since currently those could only be
introduced by peep hole rules when "ld hl, #0xf

SDCC should emit only one of the variants. That is the variant then used
in the peephole optimizer. The other variant thus will occur only in
hand-written asm,
Hi,
Imho, it is better to add two pair rules which converts (hl+/-) to ldi/ldd.
And others use ldd/ldi only.
