2013-01-01Added DEBUG message when ObjCARC replaces a call which returns its argument ↵Michael Gottesman
verbatim with its argument to temporarily undo an optimization. Specifically these calls return their argument verbatim, as a low-level optimization. However, this makes high-level optimizations harder. We undo any uses of this optimization that the front-end emitted. We redo them later in the contract pass. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171346 91177308-0d34-0410-b5e6-96231b3b80d8

2012-12-31Make it explicit that the only entry points to the Program object areChandler Carruth
through the static helper functions. This is already true throughout the codebase. Slowly, I'm going to re-implement these static helpers in terms of a new process based interface which can expose more information, and remove the program object entirely. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171335 91177308-0d34-0410-b5e6-96231b3b80d8

2012-12-31Go ahead and get rid of the old page size interface and convert all theChandler Carruth
users over to the new one. No sense maintaining this "compatibility" layer it seems. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171331 91177308-0d34-0410-b5e6-96231b3b80d8
2012-12-31Flesh out a page size accessor in the new API.Chandler Carruth
Implement the old API in terms of the new one. This simplifies the implementation on Windows which can now re-use the self_process's once initialization. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171330 91177308-0d34-0410-b5e6-96231b3b80d8
2012-12-31Remove the declspecs from small alignments that we can force withChandler Carruth
a union. These don't actually work for by-value function arguments, and MSVC warns if they exist even while (we hope) it aligns the argument correctly due to the other union member. This means MSVC will miss out on optimizations based on the alignment of the buffer, but really, there aren't that many for x86 and MSVC is likely not doing a great job of optimizing LLVM and Clang anyways. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171328 91177308-0d34-0410-b5e6-96231b3b80d8

2012-12-31Begin sketching out the process interface.Chandler Carruth
The coding style used here is not LLVM's style because this is modeled after a Boost interface and thus done in the style of a candidate C++ standard library interface. I'll probably end up proposing it as a standard C++ library if it proves to be reasonably portable and useful. This is just the most basic parts of the interface -- getting the process ID out of it. However, it helps sketch out some of the boiler plate such as the base class, derived class, shared code, and static factory function. It also introduces a unittest so that I can incrementally ensure this stuff works. However, I've not even compiled this code for Windows yet. I'll try to fix any Windows fallout from the bots, and if I can't fix it I'll revert and get someone on Windows to help out. There isn't a lot more that is mandatory, so soon I'll switch to just stubbing out the Windows side and get Michael Spencer to help with implementation as he can test it directly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171289 91177308-0d34-0410-b5e6-96231b3b80d8
2012-12-31Start sketching out a roadmap for better subprocess management in theChandler Carruth
LLVM libraries. Also, clean up the doxygen and formatting of the existing interfaces. With this change I'm calling the existing interface "legacy" because I'd like to replace it with something much better. My end goal is to expose a common set of interfaces for inspecting various properties of a process, and implementations to expose those both for the current process and for child processes. This will also expose more rich interfaces for spawning and controling a subprocess, notably to use system calls like wait3 and wait4 where available and gather detailed resource usage stats about the subprocess. My plan (discussed with Michael Spencer on IRC) is to base this loosely around the proposed Boost.Process interface, but to implement a relatively small subset of that functionality based around the needs of LLVM, Clang, the Clang driver, etc. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171285 91177308-0d34-0410-b5e6-96231b3b80d8
