The immediate fword is loaded into the lo half of a 64BIT register. The high half is zeroed.
Not all instructions that operate on wide registers have g in their names On Oct 21, 2016 9:31 AM, "Charles Mills" <[email protected]> wrote: I'm trying to figure out for certain all of what LLILF does. Based on the description it would seem to be "grande" in effect but has no G in the op code. The description says "The second operand is placed in bit positions of the first operand. The remainder of the first operand is set to zeros. ... LLILF 32-63." That second sentence would imply to me that the immediate value effectively is loaded into positions 0 to 63 of the register (without sign propagation), but the lack of a G in the op code makes me suspicious. Does anyone know *for certain*?
