2011-07-12Revert r134888 (and related patches in other trees). It was causingBill Wendling
an assert on Darwin llvm-gcc builds.

2011-07-11Fix a lot of problems with the partial destruction of arrays:John McCall
- an off-by-one error in emission of irregular array limits for InitListExprs - use an EH partial-destruction cleanup within the normal array-destruction cleanup - get the branch destinations right for the empty check Also some refactoring which unfortunately obscures these changes. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@134890 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@134880 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-10implement a nice new optimization: CodeGenTypes::UpdateCompletedTypeChris Lattner
is called whenever a tag type is completed. We previously used that as the sign to layout the codegen representation for the tag type, which worked but meant that we laid out *every* completed type, whether it was used or not. Now we just lay out the type if we've already seen it somehow else. This means that we lay out types we've used but haven't seen a body for, but we don't lay out tons of stuff that noone cares about. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@134866 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-10enhance EmitLValueForFieldInitialization to do the proper pointer ↵Chris Lattner
adjustment, allowing us to revert the other half of r134860. Now things are back to a relatively tidy state. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@134865 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-10revert part of r134860, which is empirically unnecessary after the proper fixChris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@134864 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-10keep track of whether being in a RS_StructPointer stateChris Lattner
caused us to skip layout out a function accurately. If so, flush the type cache for both the function and struct case to ensure that any pointers to the functions get recomputed. This is overconservative, but with this patch clang can build itself again. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@134863 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-10change EmitLValueForField to cast the returned lvalue to the rightChris Lattner
type, even when in the struct case. This was one root issue that was causing type mismatches throughout the compiler. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@134862 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-10Fix the clang bootstrap and Jay's testcase from llvm-dev by being completelyChris Lattner
conservative when converting a functiontype to IR when in a "pointer within a struct" context. This has the unfortunate sideeffect of compiling all function pointers inside of structs into "{}*" which, though correct, is ugly. This has the positive side effect of being correct, and it is pretty straight-forward to improve on this. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@134861 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-10when emitting pointer load from an lvalue or storing to an lvalue,Chris Lattner
do an explicit bitcast to whatever ConvertType produces. This will go with the next patch. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@134860 91177308-0d34-0410-b5e6-96231b3b80d8

2011-07-10Rename CGT::VerifyFuncTypeComplete to isFuncTypeConvertible sinceChris Lattner
it is a predicate, not an action. Change the return type to be a bool, not the incomplete member. Enhace it to detect the recursive compilation case, allowing us to compile Eli's testcase on llvmdev: struct T { struct T (*p)(void); } t; into: %struct.T = type { {}* } @t = common global %struct.T zeroinitializer, align 8 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@134853 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-09when an enum type is completed, only flush the type cache whenChris Lattner
the enum has already been converted. If not, there cannot be any types built on top of it, so there is no need to flush the cache. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@134841 91177308-0d34-0410-b5e6-96231b3b80d8

2011-07-09A number of array-related IR-gen cleanups.John McCall
- Emit default-initialization of arrays that were partially initialized with initializer lists with a loop, rather than emitting the default initializer N times; - support destroying VLAs of non-trivial type, although this is not yet exposed to users; and - support the partial destruction of arrays initialized with initializer lists when an initializer throws an exception. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@134784 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-08Change -mno-mmx to be more compatible with gcc. Specifically, -mno-mmx ↵Eli Friedman
should not imply -mno-sse. Note that because we don't usually touch the MMX registers anyway, all -mno-mmx needs to do is tweak the x86-32 calling convention a little for vectors that look like MMX vectors, and prevent the definition of __MMX__. clang doesn't actually stop the user from using MMX inline asm operands or MMX builtins in -mno-mmx mode; as a QOI issue, it would be nice to diagnose, but I doubt it really matters much. <rdar://problem/9694837> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@134770 91177308-0d34-0410-b5e6-96231b3b80d8

2011-07-07In ARC, reclaim all return values of retainable type, not just thoseJohn McCall
where we have an immediate need of a retained value. As an exception, don't do this when the call is made as the immediate operand of a __bridge retain. This is more in the way of a workaround than an actual guarantee, so it's acceptable to be brittle here. rdar://problem/9504800 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@134605 91177308-0d34-0410-b5e6-96231b3b80d8

2011-07-06Change the driver's logic about Objective-C runtimes: abstract out aJohn McCall
structure to hold inferred information, then propagate each invididual bit down to -cc1. Separate the bits of "supports weak" and "has a native ARC runtime"; make the latter a CodeGenOption. The tool chain is still driving this decision, because it's the place that has the required deployment target information on Darwin, but at least it's better-factored now. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@134453 91177308-0d34-0410-b5e6-96231b3b80d8
