Brian Gaeke 8863de761d Strange as it may sound, we'll not use LDD/STD to store longs. For reasons of

Brian Gaeke fcc30aca1b Mess around with allocation order. In particular, I think we ought to be

Brian Gaeke c4ee938f55 Support generating machine instructions for Phi nodes (based on x86, but with
modifications for 1 LLVM BB --> many MBBs).
Fix store operand order: make it always be Base, Offset, SrcReg (think
"[ Base + Offset ] = SrcReg").
Rewrite visitBranchInst() to be even dumber (but working) -- give up on
the branch fallthrough trick, for the time being.
Make visitSetCondInst() work.

llvm-svn: 14208

Brian Gaeke 1096ba9422 Add support for widening integral casts.
Flesh out the SetCC support... which currently ends in a little bit
of unfinished code (which is probably completely hilarious) for
generating the condition value splitting the basic block up into 4
blocks, like this (clearly a better API is needed for this!):

       BB
   cond. branch
     /         /          R1=1    R2=0
     \      /

Disable the code that copies long constants to registers - it looks fishy.
Implement some simple casts: integral, smaller than longs, and equal-width

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
