Teach MemoryBuiltins and InstructionSimplify that operator new never returns NULL. This is safe per C++11 18.6.1.1p3: [operator new returns] a non-null pointer to suitably aligned storage (3.7.4), or else throw a bad_alloc exception. This requirement is binding on a replacement version of this function. Brings us a tiny bit closer to eliminating more vector push_backs. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@191310 91177308-0d34-0410-b5e6-96231b3b80d8

Reverting r171325 & r172363. This was causing a mis-compile on the self-hosted LTO build bots. Okay, here's how to reproduce the problem: 1) Build a Release (or Release+Asserts) version of clang in the normal way. 2) Using the clang & clang++ binaries from (1), build a Release (or Release+Asserts) version of the same sources, but this time enable LTO --- specify the `-flto' flag on the command line. 3) Run the ARC migrator tests: $ arcmt-test --args -triple x86_64-apple-darwin10 -fsyntax-only -x objective-c++ ./src/tools/clang/test/ARCMT/cxx-rewrite.mm You'll see that the output isn't correct (the whitespace is off). The mis-compile is in the function `RewriteBuffer::RemoveText' in the clang/lib/Rewrite/Core/Rewriter.cpp file. When that function and RewriteRope.cpp are compiled with LTO and the `arcmt-test' executable is regenerated, you'll see the error. When those files are not LTO'ed, then the output of the `arcmt-test' is fine. It is *really* hard to get a testcase out of this. I'll file a PR with what I have currently. --- Reverse-merging r172363 into '.': U include/llvm/Analysis/MemoryBuiltins.h U lib/Analysis/MemoryBuiltins.cpp --- Reverse-merging r171325 into '.': U test/Transforms/InstCombine/objsize.ll G include/llvm/Analysis/MemoryBuiltins.h G lib/Analysis/MemoryBuiltins.cpp git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@172756 91177308-0d34-0410-b5e6-96231b3b80d8

Move all of the header files which are involved in modelling the LLVM IR into their new header subdirectory: include/llvm/IR. This matches the directory structure of lib, and begins to correct a long standing point of file layout clutter in LLVM. There are still more header files to move here, but I wanted to handle them in separate commits to make tracking what files make sense at each layer easier. The only really questionable files here are the target intrinsic tablegen files. But that's a battle I'd rather not fight today. I've updated both CMake and Makefile build systems (I think, and my tests think, but I may have missed something). I've also re-sorted the includes throughout the project. I'll be committing updates to Clang, DragonEgg, and Polly momentarily. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171366 91177308-0d34-0410-b5e6-96231b3b80d8

Use the new script to sort the includes of every file under lib. Sooooo many of these had incorrect or strange main module includes. I have manually inspected all of these, and fixed the main module include to be the nearest plausible thing I could find. If you own or care about any of these source files, I encourage you to take some time and check that these edits were sensible. I can't have broken anything (I strictly added headers, and reordered them, never removed), but they may not be the headers you'd really like to identify as containing the API being implemented. Many forward declarations and missing includes were added to a header files to allow them to parse cleanly when included first. The main module rule does in fact have its merits. =] git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169131 91177308-0d34-0410-b5e6-96231b3b80d8

Revert the series of commits starting with r166578 which introduced the getIntPtrType support for multiple address spaces via a pointer type, and also introduced a crasher bug in the constant folder reported in PR14233. These commits also contained several problems that should really be addressed before they are re-committed. I have avoided reverting various cleanups to the DataLayout APIs that are reasonable to have moving forward in order to reduce the amount of churn, and minimize the number of commits that were reverted. I've also manually updated merge conflicts and manually arranged for the getIntPtrType function to stay in DataLayout and to be defined in a plausible way after this revert. Thanks to Duncan for working through this exact strategy with me, and Nick Lewycky for tracking down the really annoying crasher this triggered. (Test case to follow in its own commit.) After discussing with Duncan extensively, and based on a note from Micah, I'm going to continue to back out some more of the more problematic patches in this series in order to ensure we go into the LLVM 3.2 branch with a reasonable story here. I'll send a note to llvmdev explaining what's going on and why. Summary of reverted revisions: r166634: Fix a compiler warning with an unused variable. r166607: Add some cleanup to the DataLayout changes requested by Chandler. r166596: Revert "Back out r166591, not sure why this made it through since I cancelled the command.

Make MemoryBuiltins aware of TargetLibraryInfo. This disables malloc-specific optimization when -fno-builtin (or -ffreestanding) is specified. This has been a problem for a long time but became more severe with the recent memory builtin improvements. Since the memory builtin functions are used everywhere, this required passing TLI in many places. This means that functions that now have an optional TLI argument, like RecursivelyDeleteTriviallyDeadFunctions, won't remove dead mallocs anymore if the TLI argument is missing. I've updated most passes to do the right thing. Fixes PR13694 and probably others. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@162841 91177308-0d34-0410-b5e6-96231b3b80d8

MemoryBuiltins: Properly guard ObjectSizeOffsetVisitor against cycles in the IR. The previous fix only checked for simple cycles, use a set to catch longer cycles too.

refactor the MemoryBuiltin analysis: - provide more extensive set of functions to detect library allocation functions (e.g., malloc, calloc, strdup, etc) - provide an API to compute the size and offset of an object pointed by Move a few clients (GVN, AA, instcombine, ...) to the new API. This implementation is a lot more aggressive than each of the custom implementations being replaced.

Add C++ global operator {new,new[],delete,delete[]}(unsigned {int,long}) to the memory builtins as equivalent to malloc/free. This is different from any attribute we have. For example, you can delete the allocators when their result is unused, but you can't collapse two calls to the same function, even if no global/memory state has changed in between. The noalias return states that the result does not alias any other pointer, but instcombine optimizes malloc() as though the result is non-null for the purpose of eliminating unused pointers. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@127673 91177308-0d34-0410-b5e6-96231b3b80d8

Re-commit r86077 now that r86290 fixes the 179.art and 175.vpr ARM regressions. Here is the original commit message: This commit updates malloc optimizations to operate on malloc calls that have constant int size arguments. Update CreateMalloc so that its callers specify the size to allocate: MallocInst-autoupgrade users use non-TargetData-computed allocation sizes. Optimization uses use TargetData to compute the allocation size. Now that malloc calls can have constant sizes, update isArrayMallocHelper() to use TargetData to determine the size of the malloced type and the size of malloced arrays. Extend getMallocType() to support malloc calls that have non-bitcast uses. Update OptimizeGlobalAddressOfMalloc() to optimize malloc calls that have non-bitcast uses. The bitcast use of a malloc call has to be treated specially here because the uses of the bitcast need to be replaced and the bitcast needs to be erased (just like the malloc call) for OptimizeGlobalAddressOfMalloc() to work correctly. Update PerformHeapAllocSRoA() to optimize malloc calls that have non-bitcast uses. The bitcast use of the malloc is not handled specially here because ReplaceUsesOfMallocWithGlobal replaces through the bitcast use. Update OptimizeOnceStoredGlobal() to not care about the malloc calls' bitcast use. Update all globalopt malloc tests to not rely on autoupgraded-MallocInsts, but instead use explicit malloc calls with correct allocation sizes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@86311 91177308-0d34-0410-b5e6-96231b3b80d8

Extend getMallocArraySize() to determine the array size if the malloc argument is: ArraySize * ElementSize ElementSize * ArraySize ArraySize << log2(ElementSize) ElementSize << log2(ArraySize) Refactor isArrayMallocHelper and delete isSafeToGetMallocArraySize, so that there is only 1 copy of the malloc array determining logic. Update users of getMallocArraySize() to not bother calling isArrayMalloc() as well. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@85421 91177308-0d34-0410-b5e6-96231b3b80d8
