[avr-gcc-list] .macro error "constant value required"

[darkschine]

Hi guys, recently started using avr-gcc for assembly programming and I'm
having alot of trouble getting my macro's to work properly.

This is a test file I'm using:
#####################################
.macro testMacro data
  ser data
.endm

.global main
main:

testMacro r16

end: rjmp end
#################################
this is the output:
################################
address@hidden:~/workspace/3117/project/LCD$ make
avr-gcc -g -mmcu=atmega328p -Wall -Wstrict-prototypes -Os -mcall-prologues
-O0 -c lcd.S
lcd.S: Assembler messages:
lcd.S:8: Error: constant value required
lcd.S:8: Error: register number above 15 required
make: *** [lcd.o] Error 1
###################################

I think it's complaining that r16 is not a constant, and since the
assignment failed, it complains that "data" is not a register above 15. I
understand that the value in r16 isn't a constant, but it's the address of
r16 I want to send to the macro. Even when I change r16 to 0x10 I get the
same error. The compiler must pick up that 0x10 is the address of r16

can anyone help me with this please?
