2011-03-13Add comment as following:Jin-Gu Kang
load and store reference same memory location, the memory location is represented by getelementptr with two uses (load and store) and the getelementptr's base is alloca with single use. At this point, instructions from alloca to store can be removed. (this pattern is generated when bitfield is accessed.) For example, %u = alloca %struct.test, align 4 ; [#uses=1] %0 = getelementptr inbounds %struct.test* %u, i32 0, i32 0;[#uses=2] %1 = load i8* %0, align 4 ; [#uses=1] %2 = and i8 %1, -16 ; [#uses=1] %3 = or i8 %2, 5 ; [#uses=1] store i8 %3, i8* %0, align 4 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@127565 91177308-0d34-0410-b5e6-96231b3b80d8

2011-03-12Spill multiple registers at once.Jakob Stoklund Olesen
Live range splitting can create a number of small live ranges containing only a single real use. Spill these small live ranges along with the large range they are connected to with copies. This enables memory operand folding and maximizes the spill to fill distance. Work in progress with known bugs. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@127529 91177308-0d34-0410-b5e6-96231b3b80d8

2011-03-12That's it, I am declaring this a failure of the C++03 STL.Jakob Stoklund Olesen
There are too many compatibility problems with using mixed types in std::upper_bound, and I don't want to spend 110 lines of boilerplate setting up a call to a 10-line function. Binary search is not /that/ hard to implement correctly. I tried terminating the binary search with a linear search, but that actually made the algorithm slower against my expectation. Most live intervals have less than 4 segments. The early test against endIndex() does pay, and this version is 25% faster than plain std::upper_bound(). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@127522 91177308-0d34-0410-b5e6-96231b3b80d8

2011-03-11Roll r127459 back in:Cameron Zwarich
Optimize trivial branches in CodeGenPrepare, which often get created from the lowering of objectsize intrinsics. Unfortunately, a number of tests were relying on llc not optimizing trivial branches, so I had to add an option to allow them to continue to test what they originally tested. This fixes <rdar://problem/8785296> and <rdar://problem/9112893>. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@127498 91177308-0d34-0410-b5e6-96231b3b80d8
