| | | | | | | non-deterministic. Returns NULL when it's empty! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28560 91177308-0d34-0410-b5e6-96231b3b80d8
* Fix a nasty dag combiner bug that caused nondeterminstic crashes (MY FAVORITE!):Chris Lattner2006-05-27
| | | | | | | | | | | | | | | | | | | SimplifySelectOps would eliminate a Select, delete it, then return true. The clients would see that it did something and return null. The top level would see a null return, and decide that nothing happened, proceeding to process the node in other ways: boom. The fix is simple: clients of SimplifySelectOps should return the select node itself. In order to catch really obnoxious boogs like this in the future, add an assert that nodes are not deleted. We do this by checking for a sentry node type that the SDNode dtor sets when a node is destroyed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28514 91177308-0d34-0410-b5e6-96231b3b80d8
* Make CALL node consistent with RET node. Signness of value has type MVT::i32Evan Cheng2006-05-26
| | | | | | | | instead of MVT::i1. Either is fine except MVT::i32 is probably a legal type for most (if not all) platforms while MVT::i1 is not. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28511 91177308-0d34-0410-b5e6-96231b3b80d8

* Fixed a LowerCallTo and LowerArguments bug. They were introducing illegalEvan Cheng2006-05-17
| | | | | | | | | 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28352 91177308-0d34-0410-b5e6-96231b3b80d8

* When we legalize target nodes, do not use getNode to create a new node,Chris Lattner2006-05-17
| | | | | | | | | | | | | 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28348 91177308-0d34-0410-b5e6-96231b3b80d8
