* IR: Properly canonicalize PointerType in ConstantExpr GEPsDavid Majnemer2013-11-071-5/+6
| | | | | | | | No additional test was needed, Other/constant-fold-gep.ll detects this just fine. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@194221 91177308-0d34-0410-b5e6-96231b3b80d8
* IR: Do not canonicalize constant GEPs into an out-of-bounds array accessDavid Majnemer2013-11-071-1/+37
| | | | | | | | | | | | | | | | | | | | | | | | | | Summary: Consider a GEP of: i8* getelementptr ({ [2 x i8], i32, i8, [3 x i8] }* @main.c, i32 0, i32 0, i64 0) If we proceeded to GEP the aforementioned object by 8, would form a GEP of: i8* getelementptr ({ [2 x i8], i32, i8, [3 x i8] }* @main.c, i32 0, i32 0, i64 8) Note that we would go through the first array member, causing an out-of-bounds accesses. This is problematic because we might get fooled if we are trying to evaluate loads using this GEP, for example, based off of an object with a constant initializer where the array is zero. This fixes PR17732.

* IR: Don't constant fold GEP bitcasts between different address spacesMeador Inge2013-02-271-13/+22
| | | | | | | | | | | | | | | | | | PR15262 reported a bug where the following instruction: i8 getelementptr inbounds i8* bitcast ([4 x i8] addrspace(12)* @buf to i8*), i32 2 was getting folded into: addrspace(12)* getelementptr inbounds ([4 x i8] addrspace(12)* @buf, i32 0, i32 2) This caused instcombine to crash because the original instruction and the folded instruction have different types. The issue was fixed by disallowing bitcasts between different address spaces to be folded away. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@176156 91177308-0d34-0410-b5e6-96231b3b80d8

* Make APFloat constructor require explicit semantics.Tim Northover2013-01-221-4/+4
| | | | | | | | | Previously we tried to infer it from the bit width size, with an added IsIEEE argument for the PPC/IEEE 128-bit case, which had a default value. This default value allowed bugs to creep in, where it was inappropriate. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@173138 91177308-0d34-0410-b5e6-96231b3b80d8
* Move all of the header files which are involved in modelling the LLVM IRChandler Carruth2013-01-021-7/+7
| | | | | | | | | | | | | | | | | | | | | 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
* Rename VMCore directory to IR.Chandler Carruth2013-01-021-0/+2066
Aside from moving the actual files, this patch only updates the build system and the source file comments under lib/... that are relevant. I'll be updating other docs and other files in smaller subsequnet commits. While I've tried to test this, but it is entirely possible that there will still be some build system fallout. Also, note that I've not changed the library name itself: libLLVMCore.a is still the library name. I'd be interested in others' opinions about whether we should rename this as well (I think we should, just not sure what it might break) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171359 91177308-0d34-0410-b5e6-96231b3b80d8
