Make variable name more explicit and eliminate redundant lookup in SDNodeOrdering

When computing the demanded bits of Load SDNodes, make sure that we are looking at the loaded-value operand and not the ptr result (in case of pre-inc loads).

Revert "pre-RA-sched: fix TargetOpcode usage"

2013-03-20T15:43:00Z

This reverts commit 06091513c283c863296f01cc7c2e86b56bb50d02. The code is obviously wrong, but the trivial fix causes inefficient code generation on X86. Somebody with more knowledge of the code needs to take a look here.

Move SDNode order propagation to SDNodeOrdering, which also fixes a missed

case of order propagation during isel. Thanks Owen for the suggestion! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@177525 91177308-0d34-0410-b5e6-96231b3b80d8

pre-RA-sched: fix TargetOpcode usage

2013-03-20T13:49:22Z

TargetOpcodes need to be treaded as Machine- and not ISD-Opcodes. Signed-off-by: Christian König git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@177518 91177308-0d34-0410-b5e6-96231b3b80d8

Propagate DAG node ordering during type legalization and instruction selection

2013-03-20T00:10:32Z

A node's ordering is only propagated during legalization if (a) the new node does not have an ordering (is not a CSE'd node), or (b) the new node has an ordering that is higher than the node being legalized. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@177465 91177308-0d34-0410-b5e6-96231b3b80d8

Move #include of BitVector from .h to .cpp file.

Also remove unneeded #include and forward declaration. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@177357 91177308-0d34-0410-b5e6-96231b3b80d8

Fix integer comparison in DIEInteger::BestForm.

2013-03-18T17:03:05Z

The always-true "(int)Int == (signed)Int" comparison was found while experimenting with a potential new Clang warning. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@177290 91177308-0d34-0410-b5e6-96231b3b80d8
