2008-10-04	Ignore loads from and stores to local memory (i.e. allocas)	Duncan Sands
	when deciding whether to mark a function readnone/readonly. Since the pass is currently run before SROA, this may be quite helpful. Requested by Chris on IRC. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@57050 91177308-0d34-0410-b5e6-96231b3b80d8
2008-09-30	add AU.setPreservesCFG() since this pass only adds and removes function ↵	Nuno Lopes

2008-09-29	Speed up these passes when the callgraph has	Duncan Sands
	huge simply connected components. Suggested by Chris. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@56787 91177308-0d34-0410-b5e6-96231b3b80d8

2008-09-29	Rename isWeakForLinker to mayBeOverridden. Use it	Duncan Sands
	instead of hasWeakLinkage in a bunch of optimization passes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@56782 91177308-0d34-0410-b5e6-96231b3b80d8
2008-09-26	Now Attributes are divided in three groups	Devang Patel
	- return attributes - inreg, zext and sext - parameter attributes - function attributes - nounwind, readonly, readnone, noreturn Return attributes use 0 as the index. Function attributes use ~0U as the index. This patch requires corresponding changes in llvm-gcc and clang. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@56704 91177308-0d34-0410-b5e6-96231b3b80d8
2008-09-25	Large mechanical patch.	Devang Patel
	s/ParamAttr/Attribute/g s/PAList/AttrList/g s/FnAttributeWithIndex/AttributeWithIndex/g s/FnAttr/Attribute/g This sets the stage - to implement function notes as function attributes and - to distinguish between function attributes and return value attributes. This requires corresponding changes in llvm-gcc and clang. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@56622 91177308-0d34-0410-b5e6-96231b3b80d8
2008-09-20	Implement review feedback from Devang: make use	Duncan Sands
	of mayReadFromMemory and mayWriteToMemory. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@56387 91177308-0d34-0410-b5e6-96231b3b80d8
2008-09-19	Add a new pass AddReadAttrs which works out which functions	Duncan Sands
	can get the readnone/readonly attributes, and gives them it. The plan is to remove markmodref (which did the same thing by querying GlobalsModRef) and delete the analogous functionality from GlobalsModRef. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@56341 91177308-0d34-0410-b5e6-96231b3b80d8
