◆ asBytes()

size_t SparcISA::SparcStaticInst::asBytes	(	void *	buf,

inlineoverrideprotectedvirtual

Instruction classes can override this function to return a a representation of themselves as a blob of bytes, generally assumed to be that instructions ExtMachInst.

buf is a buffer to hold the bytes. max_size is the size allocated for that buffer by the caller. The return value is how much data was actually put into the buffer, zero if no data was put in the buffer, or the necessary size of the buffer if there wasn't enough space.

StaticInst::StaticInst

inlineprotected

Constructor.

It's important to initialize everything here to a sane default, since the decoder generally only overrides the fields that are meaningful for the particular instruction.
