problem passing constants to inline asm

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi.

I am trying to write something like this:

 asm volatile (".space %0\n" :: "i"(sizeof(var)));

but this doesn't work because "i" prepends the number
with the $ sign.
I've only found the following hack to cheat gcc:

 asm volatile (".space %0\n" :: "m"(*(long*)sizeof(var)));

but that's quite nasty and doesn't work with -O0.

So, what is the right way of passing the constants to those
"Special Dot Symbols" of gas?
