Evan Cheng 401049ce33 - Use of load's chain result should be redirected to load's chain operand.
If it reads the chain result of the call, then the use, callseq_start,
  and call would form a cycle!
- Don't forget handle node replacement!
- There could also be a TokenFactor between the load and the callseq_start.

Reid Spencer a22a5b382f Make some changes suggested by Chris:
1. Remove the LLVM_DO_NOT_BUILD feature (not needed any more)
2. Ensure that lib/VMCore gets built first. This needs to be done because
   VMCore now uses tblgen to generate the Intrinsics header which are
   needed in other libraries. In parallel builds, this can cause problems.

Evan Cheng 751cd7653d Fixed a LowerCallTo and LowerArguments bug. They were introducing illegal
VBIT_VECTOR nodes. There were some confusion about the semantics of
getPackedTypeBreakdown(). e.g. for <4 x f32> it returns 1 and v4f32, not 4,
and f32.

llvm-svn: 28349
2006-05-17 18:05:35 +00:00
Chris Lattner 62f1b83c0e When we legalize target nodes, do not use getNode to create a new node,
use UpdateNodeOperands to just update the operands!  This is important because
getNode will allocate a new node if the node returns a flag and this breaks
assumptions in the legalizer that you can legalize some things multiple times
and get exactly the same results.

This latent bug was exposed by my ppc patch last night, and this fixes
gsm/toast.

Chris Lattner b1e9e37c58 Switch PPC over to a call-selection model where the lowering code creates
the copyto/fromregs instead of making the PPCISD::CALL selection code create
them.  This vastly simplifies the selection code, and moves the ABI handling
parts into one place.

llvm-svn: 28346
2006-05-17 06:01:33 +00:00
Chris Lattner b7552a88d6 3 changes, 2 of which are cleanup one of which changes codegen:
1. Rearrange code a bit so that the special case doesn't require indenting lots
   of code.
2. Add comments describing PPC calling convention.
3. Only round up to 56-bytes of stack space for an outgoing call if the callee
   is varargs.  This saves a bit of stack space.

Chris Lattner aa40ec1b32 Instead of implementing LowerCallTo directly, let the default impl produce an
ISD::CALL node, then custom lower that.  This means that we only have to handle
LEGAL call operands/results, not every possible type.  This allows us to
simplify the call code, shrinking it by about 1/3.

2006-05-16 18:51:52 +00:00
Chris Lattner 4302e8fb67 Switch the PPC backend over to using FORMAL_ARGUMENTS for formal argument
handling.  This makes the lower argument code significantly simpler (we
only need to handle legal argument types).

Incidentally, this also implements support for vector argument registers,
so long as they are not on the stack.
