336b83623a I don't think we have to have 4 extra allocated (but unused) bytes on the stack.

3e29bc5a19 Support loading arguments from %I0...%I5 into virtual registers in 
function prologues, and fix an off-by-one in visitCallInst that was
putting call args into the wrong registers.

3eb6c1d3ae It's setting up the call args right now, but on the callee side, it's 
trying to get incoming args off the stack, instead of the %i0...%i6 regs,
which is wrong.

37a392dc52 This is a start on handling setcc instructions. As the comment notes, we 
have no good way of handling this until the code generator is improved.
We should probably just emit V9 instructions in the meantime.

0d35bd3ca9 Preliminary support for getting 64-bit integer constants into registers. 
Preliminary support for division. It's gross because you have to initialize
the "Y" register, which is the top 32 bits of the thing you're dividing.

just a typo or something somewhere.
