* Replace archive members in the old position.Rafael Espindola2013-07-222-51/+97
| | | | | | | | | | | | This matches gnu archive behavior and since archive member order can change which member is used, not changing the order on replacement looks like the right thing to do. This patch also refactors the logic for which archive member to keep and whether to move it to a helper function (computeInsertAction). The nesting in computeNewArchiveMembers was getting a bit confusing. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@186829 91177308-0d34-0410-b5e6-96231b3b80d8
* Don't depend on a llvm-ar specific behavior.Rafael Espindola2013-07-221-1/+2
| | | | | | | | GNU ar when not given the a or b modifiers replaces archive members in the same location of the old ones. I am about to implement that in llvm-ar. For now, just don't depend on the current llvm-ar behavior on this test. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@186823 91177308-0d34-0410-b5e6-96231b3b80d8

* Hoist the rest of the logic for promoting single-store allocas into theChandler Carruth2013-07-211-23/+31
| | | | | | | | | | | | helper function. This leaves both trivial cases handled entirely in helper functions and merely manages the list of allocas to process in the run method. The next step will be to handle all of the trivial promotion work prior to even creating the core class and the subsequent simplifications that enables. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@186784 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | a single block into the helper routine. This takes advantage of the fact that we can directly replace uses prior to any store with undef to simplify matters and unconditionally promote allocas only used within one block. I've removed the special handling for the case of no stores existing. This has no semantic effect but might slow things down. I'll fix that in a later patch when I refactor this entire thing to be easier to manage the different cases. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@186783 91177308-0d34-0410-b5e6-96231b3b80d8

* Hoist the two trivial promotion routines out of the big class thatChandler Carruth2013-07-201-161/+158
| | | | | | | | | | | | | | | handles the general cases. The hope is to refactor this so that we don't end up building the entire class for the trivial cases. I also want to lift a lot of the early pre-processing in the initial segment of run() into a separate routine, and really none of it needs to happen inside the primary promotion class. These routines in particular used none of the actual state in the promotion class, so they don't really make sense as members. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@186781 91177308-0d34-0410-b5e6-96231b3b80d8

* Refactor AnalyzeBranch on ARM. The previous version did not always analyzeLang Hames2013-07-193-91/+102
| | | | | | | | | | | | | | | | | | | | indirect branches correctly. Under some circumstances, this led to the deletion of basic blocks that were the destination of indirect branches. In that case it left indirect branches to nowhere in the code. This patch replaces, and is more general than either of the previous fixes for indirect-branch-analysis issues, r181161 and r186461. For other branches (not indirect) this refactor should have *almost* identical behavior to the previous version. There are some corner cases where this refactor is able to analyze blocks that the previous version could not (e.g. this necessitated the update to thumb2-ifcvt2.ll). <rdar://problem/14464830> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@186735 91177308-0d34-0410-b5e6-96231b3b80d8
