2009-12-07Introduce the "@llvm.dbg.value" debug intrinsic.Victor Hernandez
The semantics of llvm.dbg.value are that starting from where it is executed, an offset into the specified user source variable is specified to get a new value. An example: call void @llvm.dbg.value(metadata !{ i32 7 }, i64 0, metadata !2) Here the user source variable associated with metadata #2 gets the value "i32 7" at offset 0. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@90788 91177308-0d34-0410-b5e6-96231b3b80d8

2009-12-04add the start of a class used to handle phi translation in memdep andChris Lattner

2009-11-27teach GVN's load PRE to insert computations of the address in predecessorsChris Lattner
where it is not available. It's unclear how to get this inserted computation into GVN's scalar availability sets, Owen, help? :) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@89997 91177308-0d34-0410-b5e6-96231b3b80d8

2009-11-26Implement PR1143 (at -m64) by making basicaa look through extensions. WeChris Lattner
previously already handled it at -m32 because there were no i32->i64 extensions for addressing. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@89959 91177308-0d34-0410-b5e6-96231b3b80d8

2009-11-22Remove the AliasAnalysis::getMustAliases method, which is dead.Chris Lattner
The hasNoModRefInfoForCalls isn't worth it as a filter because basicaa provides m/r info and everything chains to it, so remove it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@89599 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-20Make Loop::getLoopLatch() work on loops which don't have preheaders, asDan Gohman
it may be used in contexts where preheader insertion may have failed due to an indirectbr. Make LoopSimplify's LoopSimplify::SeparateNestedLoop properly fail in the case that it would require splitting an indirectbr edge. These fix PR5502. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@89484 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-19Extend CaptureTracking to indicate when a value is never stored, evenDan Gohman
if it is not ultimately captured. Teach BasicAliasAnalysis that a local object address which does not escape and is never stored does not alias with a value resulting from a load. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@89398 91177308-0d34-0410-b5e6-96231b3b80d8

2009-11-12- Teach LSR to avoid changing cmp iv stride if it will create an immediate thatEvan Cheng
cannot be folded into target cmp instruction. - Avoid a phase ordering issue where early cmp optimization would prevent the later count-to-zero optimization. - Add missing checks which could cause LSR to reuse stride that does not have users. - Fix a bug in count-to-zero optimization code which failed to find the pre-inc iv's phi node. - Remove, tighten, loosen some incorrect checks disable valid transformations. - Quite a bit of code clean up. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@86969 91177308-0d34-0410-b5e6-96231b3b80d8

2009-11-12Do not use StringRef in DebugInfo interface. Devang Patel
This allows StringRef to skip controversial if(str) check in constructor. Buildbots, wait for corresponding clang and llvm-gcc FE check-ins! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@86914 91177308-0d34-0410-b5e6-96231b3b80d8
