* Replace OwningPtr<T> with std::unique_ptr<T>.Ahmed Charles2014-03-06
| | | | | | | | | | This compiles with no changes to clang/lld/lldb with MSVC and includes overloads to various functions which are used by those projects and llvm which have OwningPtr's as parameters. This should allow out of tree projects some time to move. There are also no changes to libs/Target, which should help out of tree targets have time to move, if necessary. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@203083 91177308-0d34-0410-b5e6-96231b3b80d8

After this commit, the only IR-library headers in include/llvm/* are ones related to the legacy pass infrastructure that I'm planning to leave there until the new one is farther along.

* Add a DIELocList class to handle pointers into the location list.Eric Christopher2014-03-05
| | | | | | | | This enables us to figure out where in the debug_loc section our locations are so that we can eventually hash them. It also helps remove some special case code in emission.

* With PPC CR bit registers, handle int_to_fp on older coresHal Finkel2014-03-05
| | | | | | | | | On cores without fpcvt support, we cannot promote int_to_fp i1 operations, because there is nothing to promote them to.

* Always print the implicit .text at the start of an asm file.Rafael Espindola2014-03-05
| | | | | | | | | | | | | | | | | Before llvm-mc would print it, but llc was assuming that it would produce another section changing directive before one was needed. That assumption is false with inline asm. Fixes PR19049. Another option would be to always create the section, but in the asm printer avoid printing sections changes during initialization. That would work, but * We do use the fact that llvm-mc prints it in testing.

* Make stackmap machineinstrs clobber the scratch regs too.Andrew Trick2014-03-05
| | | | | | | | | | | | | Patchpoints already did this. Doing it for stackmaps is a convenience for the runtime in the event that it needs to scratch register to patch or perform a runtime call thunk. Unlike patchpoints, we just assume the AnyRegCC calling convention. This is the only language and target independent calling convention specific to stackmaps so makes sense. Although the calling convention is not currently used to select the scratch registers. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@202943 91177308-0d34-0410-b5e6-96231b3b80d8

* Check for dynamic allocas and inline asm that clobbers sp before buildingHans Wennborg2014-03-05
| | | | | | | | | | | | | | | | | | | selection dag (PR19012) In X86SelectionDagInfo::EmitTargetCodeForMemcpy we check with MachineFrameInfo to make sure that ESI isn't used as a base pointer register before we choose to emit rep movs (which clobbers esi). The problem is that MachineFrameInfo wouldn't know about dynamic allocas or inline asm that clobbers the stack pointer until SelectionDAGBuilder has encountered them. This patch fixes the problem by checking for such things when building the FunctionLoweringInfo.
