* Debug Info Finder: add processScope to actually handle the Scope.Manman Ren2013-07-22
| | | | | | | Instead of just adding the scope to the list, we actually handle the scope. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@186867 91177308-0d34-0410-b5e6-96231b3b80d8

* Initialize/Register LTO passes to enable flags like -print-after=<lto-pass>Shuxin Yang2013-07-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | There already have two "dead" functions, initialize{IPO|IPA}, defined for similar purpose. I decide not to call these two functions for two reasons: o. they don't cover all LTO passes (which will soon be separated into IPO and post-IPO passes) o. We have not yet figured out the right passes and the ordering for IPO and post-IPO stages, meaning this change is only for the time being. Since LTO passes are registered, we are now able to print IR before and after particular point. For OSX users: -------------- "...-Wl,-mllvm -Wl,-print-after=<pass-name>" will print IR after the specified pass. For Other UNIX with GNU gold linker: ------------------------------------ "-Wl,-plugin-opt=-print-after=<pass-name>" should work. (NOTE: no need for "-Wl,-mllvm") Strip "-Wl," if flags are fed directly to linker instead of clang/clang++. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@186853 91177308-0d34-0410-b5e6-96231b3b80d8

* MC: mayAffectControlFlow() handling for variadic instructions.Jim Grosbach2013-07-22
| | | | | | | | | | | Variadic MC instructions don't note whether the variable operands are uses or defs, so mayAffectControlFlow() must conservatively assume they are defs and return true if the PC is in the operand list. rdar://14488628 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@186846 91177308-0d34-0410-b5e6-96231b3b80d8
* Fix an obvious typo in the loop vectorizer where the cost model uses the ↵Nadav Rotem2013-07-22
| | | | | | | | | | wrong variable. The variable BlockCost is ignored. We don't have tests for the effect of if-conversion loops because it requires a big test (that includes if-converted loops) and it is difficult to find and balance a loop to do the right thing. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@186845 91177308-0d34-0410-b5e6-96231b3b80d8

* Option parsing: allow aliases in groupsHans Wennborg2013-07-22
| | | | | | | | | Option aliases in option groups were previously disallowed by an assert. As far as I can tell, there was no technical reason for this, and I would like to be able to put cl.exe compatible options in their own group for Clang, so let's change the assert. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@186838 91177308-0d34-0410-b5e6-96231b3b80d8

* Replace archive members in the old position.Rafael Espindola2013-07-22
| | | | | | | | | | | | 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 Espindola2013-07-22
| | | | | | | | 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 Carruth2013-07-21
| | | | | | | | | | | | 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
* Hoist the rest of the logic for fully promoting allocas with all uses inChandler Carruth2013-07-21
| | | | | | | | | | | | | | 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 Carruth2013-07-20
| | | | | | | | | | | | | | | 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
