using the local & in regs first because they are not clobbered by calls.

llvm-svn: 14228

llvm-svn: 14227

Replace it with a working class for FP instrs.

llvm-svn: 14226

Add some FP moves.

llvm-svn: 14225

Use this for printing the jmpl indirect-call instruction.

llvm-svn: 14224

Support indirect calls.
Support returning a float value.

llvm-svn: 14223

llvm-svn: 14217

Support copying floating-point constants to registers.
Add assertion to visitCallInst to abort if we hit a NULL calledFunction, for now.

llvm-svn: 14216

Make copyRegToReg return 1 instead of -1.
Edit a comment in emitPrologue().

llvm-svn: 14211

Add a FIXME about the (currently unused) JMPL instructions.

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

llvm-svn: 14207

Abort if we see a PCRelativeDisp MachineOperand, to be safe. This matches
the X86 backend.

getReg() on void value.

llvm-svn: 14178

on a double-word boundary instead of a single-word boundary.

llvm-svn: 14177

non-register, non-immed. arguments to SETHI and OR using %hi() and
%lo() respectively.

llvm-svn: 14176

Support copying long constants to register pairs.
Support copying ConstantPointerNulls and ConstantPointerRefs to registers.

llvm-svn: 14175

llvm-svn: 13949

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
     \      /
      \    /
    R=phi(R1,R2)

Add support for branches (based loosely on X86/InstSelectSimple).
Add support for not visiting phi nodes in the first pass.
Add support for loading bools.
Flesh out support for stores.

llvm-svn: 13418

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.

function prologues, and fix an off-by-one in visitCallInst that was
putting call args into the wrong registers.

llvm-svn: 12757

trying to get incoming args off the stack, instead of the %i0...%i6 regs,
which is wrong.

llvm-svn: 12756

have no good way of handling this until the code generator is improved.
We should probably just emit V9 instructions in the meantime.
