Hi,
I need to assemble 24-bit integers in avr-as as if they were generated
from C code like
const __pgmx char c = 1;
const __pgmx char *pc = &c;
where __pgmx generates 24-bit addresses.
If pc just held a 16 bit address the code was
.global pc
.data
.type pc, @object
.size pc, 2
pc:
.word c
Now the question is: How to write down a 24-bit symbol?
.global pc
.data
.type pc, @object
.size pc, 3
pc:
.word c
.byte hlo8(c) ??? error from as
gives an error from the assembler, same for .byte hh8(c)
Moreover, a const-integer offset can be added to c:
.word c+2
.byte hlo8(c+2) ??? error from as
What is the right way to write it own?
Many thanks,
Johann
