2013-04-30Don't treat a non-deduced 'auto' type as being type-dependent. Instead, thereRichard Smith
are now two distinct canonical 'AutoType's: one is the undeduced 'auto' placeholder type, and the other is a deduced-but-dependent type. All deduced-to-a-non-dependent-type cases are still non-canonical. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@180789 91177308-0d34-0410-b5e6-96231b3b80d8

2012-12-04Sort all of Clang's files under 'lib', and fix up the broken headersChandler Carruth
uncovered. This required manually correcting all of the incorrect main-module headers I could find, and running the new llvm/utils/sort_includes.py script over the files. I also manually added quite a few missing headers that were uncovered by shuffling the order or moving headers up to be main-module-headers. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@169237 91177308-0d34-0410-b5e6-96231b3b80d8

2012-04-12Fix some i1/i8 confusion within _Atomic(bool) in IR generation, bothDouglas Gregor
in general (such an atomic has boolean representation) and specifically for IR generation of __c11_atomic_init. The latter also means actually using initialization semantics for this initialization, rather than just creating a store. On a related note, make sure we actually put in non-atomic-to-atomic conversions when performing an implicit conversion sequence. IR generation is far too kind here, but we still want the ASTs to make sense. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@154612 91177308-0d34-0410-b5e6-96231b3b80d8

2012-02-17Whether an argument is required (in contrast with being anJohn McCall
optional argument passed through the variadic ellipsis) potentially affects how we need to lower it. Propagate this information down to the various getFunctionInfo(...) overloads on CodeGenTypes. Furthermore, rename those overloads to clarify their distinct purposes, and make sure we're calling the right one in the right place. This has a nice side-effect of making it easier to construct a function type, since the 'variadic' bit is no longer separable. This shouldn't really change anything for our existing platforms, with one minor exception --- we should now call variadic ObjC methods with the ... in the "right place" (see the test case), which I guess matters for anyone running GNUStep on MIPS. Mostly it's just a substantial clean-up. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@150788 91177308-0d34-0410-b5e6-96231b3b80d8

2011-07-15Enhance the IR type lowering code to be much smarter about recursively loweringChris Lattner
types. Fore xample, we used to lower: struct bar { int a; }; struct foo { void (*FP)(struct bar); } G; to: %struct.foo = type { {}* } since the function pointer would cause recursive translation of bar and we didn't know if that would get us into trouble. We are now smart enough to know that it is fine, so we get this type instead: %struct.foo = type { void (i32)* } Codegen still needs to be prepared for uncooperative types at any place, which is why I let the maximally uncooperative code sit around for awhile to help shake out the bugs. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@135244 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-13per john's advice, speculatively lower uses of forward-declared enums toChris Lattner
i32. They almost always end up this way in the end anyway, and if we get lucky, this avoids generating some bitcasts. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@135032 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-12Fix a problem Eli ran into where we now reject incomplete arrays of Chris Lattner
uncompleted struct types. We now do what llvm-gcc does and compile them into [i8 x 0]. If the type is later completed, we make sure that it is appropriately cast. We compile the terrible example to something like this now: %struct.A = type { i32, i32, i32 } @g = external global [0 x i8] define void @_Z1fv() nounwind { entry: call void @_Z3fooP1A(%struct.A* bitcast ([0 x i8]* @g to %struct.A*)) ret void } declare void @_Z3fooP1A(%struct.A*) define %struct.A* @_Z2f2v() nounwind { entry: ret %struct.A* getelementptr inbounds ([0 x %struct.A]* bitcast ([0 x i8]* @g to [0 x %struct.A]*), i32 0, i64 1) } git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@134972 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-12fix an unintended behavior change in the type system rewrite, which caused ↵Chris Lattner
us to compile stuff like this: typedef struct { int x, y, z; } foo_t; foo_t g; into: %"struct.<anonymous>" = type { i32, i32, i32 } we now get: %struct.foo_t = type { i32, i32, i32 } This doesn't change the behavior of the compiler, but makes the IR much easier to read. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@134969 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
2011-07-10keep 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
2011-07-10Fix 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
