Update test: dynamic_stackalloc size must be rounded to ensure stack ptr be left in a valid state. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@41134 91177308-0d34-0410-b5e6-96231b3b80d8 2007-08-16 23:51:28 +00:00			`; RUN: llvm-as < %s \| llc -march=x86 -mtriple=i686-apple-darwin \| grep and \| count 1`
Optimize DAGCombiner's worklist processing. Previously it started its work by putting all nodes in the worklist, requiring a big dynamic allocation. Now, DAGCombiner just iterates over the AllNodes list and maintains a worklist for nodes that are newly created or need to be revisited. This allows the worklist to stay small in most cases, so it can be a SmallVector. This has the side effect of making DAGCombine not miss a folding opportunity in alloca-align-rounding.ll. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@55498 91177308-0d34-0410-b5e6-96231b3b80d8 2008-08-28 21:01:56 +00:00			`; RUN: llvm-as < %s \| llc -march=x86-64 -mtriple=i686-pc-linux \| grep and \| count 1`
It's not necessary to do rounding for alloca operations when the requested alignment is equal to the stack alignment. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@40004 91177308-0d34-0410-b5e6-96231b3b80d8 2007-07-18 16:29:46 +00:00
