2012-03-21Teach instsimplify to gracefully degrade in the presence of instructionsChandler Carruth
not attched to a basic block or function. There are conservatively correct answers in these cases, and this makes the analysis more useful in contexts where we have a partially formed bit of IR. I don't have any way to test this directly... suggestions welcome here, but I'm not seeing anything sadly. I only found this using a subsequent patch to the inliner which runs instsimplify on partially inlined instructions, and even then only on a quite large program. I never got a reasonable testcase out of it, and anything I do get is likely to be quite fragile due to requiring an interaction of two different passes, and the only result being a segfault if it goes wrong. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@153176 91177308-0d34-0410-b5e6-96231b3b80d8

2012-03-21Organize LLVM C API docs into doxygen modules; add docsGregory Szorc
This gives a lot of love to the docs for the C API. Like Clang's documentation, the C API is now organized into a Doxygen "module" (LLVMC). Each C header file is a child of the main module. Some modules (like Core) have a hierarchy of there own. The produced documentation is thus better organized (before everything was in one monolithic list). This patch also includes a lot of new documentation for APIs in Core.h. It doesn't document them all, but is better than none. Function docs are missing @param and @return annotation, but the documentation body now commonly provides help details (like the expected llvm::Value sub-type to expect). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@153157 91177308-0d34-0410-b5e6-96231b3b80d8

2012-03-20Make sure ImmutableSet never inserts Tombstone/Entry into DenseMap.Anna Zaks
ImmutAVLTree uses random unsigned values as keys into a DenseMap, which could possibly happen to be the same value as the Tombstone or Entry keys in the DenseMap. Test case is hard to come up with. We randomly get failures on the internal static analyzer bot, which most likely hits this issue (hard to be 100% sure without the full stack). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@153148 91177308-0d34-0410-b5e6-96231b3b80d8
2012-03-20RuntimeDyldMachO has the ability to keep track ofSean Callanan
relocations (i.e., pieces of data whose addresses are referred to elsewhere in the binary image) and update the references when the section containing the relocations moves. The way this works is that there is a map from section IDs to lists of relocations. Because the relocations are associated with the section containing the data being referred to, they are updated only when the target moves. However, many data references are relative and also depend on the location of the referrer. To solve this problem, I introduced a new data structure, Referrer, which simply contains the section being referred to and the index of the relocation in that section. These referrers are associated with the source containing the reference that needs to be updated, so now regardless of which end of the relocation moves, the relocation will now be updated correctly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@153147 91177308-0d34-0410-b5e6-96231b3b80d8

2012-03-20Require a base pointer for stack realignment when SP may vary dynamically.Bob Wilson
ARMBaseRegisterInfo::canRealignStack was checking for variable-sized objects but not for stack adjustments around calls. Use hasReservedCallFrame() to check for both. The hasBasePointer function was already correctly checking both conditions, so the effect of this was that a base pointer would be used without checking whether the base pointer register could be reserved. I don't have a small testcase for this. <rdar://problem/11075906> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@153110 91177308-0d34-0410-b5e6-96231b3b80d8

2012-03-20It's possible to have a constant expression who's size is quite big (e.g.,Bill Wendling
i128). In that case, we may not be able to print out the MCExpr as an expression. For instance, we could have an MCExpr like this: 0xBEEF0000BEEF0000 | (0xBEEF0000BEEF0000 << 64) The MCExpr printer handles sizes up to 64-bits, but this expression would require 128-bits. In this situation, try to evaluate the constant expression and emit that as the value into 64-bit chunks. <rdar://problem/11070338> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@153081 91177308-0d34-0410-b5e6-96231b3b80d8

themselves used by a extract_vector_elt. This was done to allow the DAG combiner to collapse to a single element load. Unfortunately, sometimes the extract_vector_elt would disappear before DAG combine could do the transformation leaving a vector_shuffle that isel couldn't handle.
