[avr-gcc-list] inline asm: how to make lds work with array elements?

[Lin Gu]

Hi,

I can get correct assembly cod for the following asm line.

asm volatile ("sts aba, r27" "\n\t" : : );

Here aba is a global char variable.

However, avr-gcc complains for the following line.

asm volatile ("sts cReg[27], r27" "\n\t" : :);

The error messages are:

/tmp/ccaTmd02.s: Assembler messages:
/tmp/ccaTmd02.s:290: Error: `,' required
/tmp/ccaTmd02.s:290: Error: garbage at end of line


So how shall I specify the address of an element in an array
in inline asm?

Thanks in advance,

lin
