Brian Gaeke 584308b71a Add support for copying bool constants to registers. 
Disable the code that copies long constants to registers - it looks fishy.
Implement some simple casts: integral, smaller than longs, and equal-width
 or narrowing only.

Brian Gaeke 6f6e4b9f59 I don't think we have to have 4 extra allocated (but unused) bytes on the stack.

Brian Gaeke 969795b4ea I started working on casts, but I don't have anything compilable yet.

Brian Gaeke 989c04ab58 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.

llvm-svn: 12757
 2004-04-07 17:04:09 +00:00
Brian Gaeke 7985e56cf9 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.

Chris Lattner bd58b3fbe9 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.

Brian Gaeke cfbfb8ac57 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.

Brian Gaeke 427cec1395 TargetCacheInfo has been removed; its only uses were to propagate a constant 
(16) into certain areas of the SPARC V9 back-end. I'm fairly sure the US IIIi's
dcache has 32-byte lines, so I'm not sure where the 16 came from. However, in
the interest of not breaking things any more than they already are, I'm going
to leave the constant alone.
