Any idea why this is necessary?
I suppose one could call it a gcc 4 issue if earlier gcc versions were unable to optimize away the dead struct init. As far as I understand the asm contraints, not specifying the structure as a mem input for the asm, makes the struct init dead code. So the mem input should be specified anyway - the code just was "lucky" with earlier gcc versions. But I'm not an expert in gcc asm.. could be something more subtle.. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
