Halves of index registers

[ammehet]

Instructions like LD XL,n and LD YH,r are not recognized while OR XL is processed correctly.
Also, LD IXL,n is recognized, but the calculated length is 2 bytes instead of 3.

Thanks for the report!
Both problems will be fixed in the next version.

It seems that instructions using any half (such as OR IXp) accepted multiple syntax for the register, while instructions using an specific half (such as LD IXl,n) were requiring a verbatim match (hence IXL was recognized but was not).

The size issue comes from the source Z80 instruction set data; I'll report it to the page maintainer.

DEC L shows 2 bytes instead of 1.

LD HL,(NN) and IN F,(C) were also wrong.
They are all fixed now; both in this extension and in the Z80 Instruction Set source data.
Thanks!
