* 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
* [Modules] Fix a layering issue that is actually impacting the modulesChandler Carruth2014-03-06
| | | | | | | | | | | | | | | | | | | | | | selfhost. The 'Core.h' C-API header is part of the IR LLVM library. (One might even argue it should be called IR.h, but that's a separate point.) We can't include it into a Support header without violating the layering, and in a way that breaks modules. MemoryBuffer's opaque C type was being defined in the Core.h C-API header despite being in the Support library, and thus we ended up with this weird issue. It turns out that there were other constructs from the Support library in the Core.h header. This patch lifts all of them into Support.h and then includes that into Core.h. The only possible fallout is if someone was including Support.h and relying on Core.h to be visible for their own uses. Considering the narrow interface actually provided by the C-API for the Support library, this seems a very, very unlikely mistake. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@203071 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. The only other headers at the top level are linking and initialization aids that aren't really libraries but just headers. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@203069 91177308-0d34-0410-b5e6-96231b3b80d8

* 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. The tests can be changed if needed. * A quick poll on IRC suggest that most developers prefer the implicit .text to be printed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@203001 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.

| | | | | | | | | | | | | | itself and teach it to convert between the non-const and const variants. De-templatetize its usage in APIs to just use the const variant which always works for those use cases. Also, rename its implementation to reflect that it is an iterator over *users* not over *uses*. This is a step toward providing both iterator and range support for walking the *uses* distinct from the *users*. In a subsequent patch this will get renamed to make it clear that this is an adaptor over the fundamental use iterator. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@202923 91177308-0d34-0410-b5e6-96231b3b80d8
