2010-04-20reapply 'reject forward references to functions whose type don't match'Chris Lattner
now that the testsuite has been updated. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101866 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-17Revert "reject forward references to functions whose type don't match", ↵Daniel Dunbar
because DJG told me to! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101675 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-17reject forward references to functions whose type don't matchChris Lattner

$ llvm-as t.ll llvm-as: t.ll:1:6: error: expected 'type' after '=' %0 = = type { i32, float, float, double } ^ PR6810. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@100934 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-07fix a crash on invalid metadata, e.g.: call i32 @foo(), XXXXChris Lattner
We would return the error without inserting the new instruction into the program, so it wouldn't get deallocated, and an abort would trigger when the module was deleted. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@100602 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-01rewrite handling of forward ref'd instruction metadata Chris Lattner
to used deferred resolution instead of creating a temporary node + rauw. There is no reason to create the temporary mdnode, then do rauw, then destroy it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@100086 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-16Introduce isOpaqueTy and use it rather than isa<OpaqueType>. Also, move someDuncan Sands
methods to try to have the type predicates be more logically positioned. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@96349 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-16There are two ways of checking for a given type, for example isa<PointerType>(T)Duncan Sands
and T->isPointerTy(). Convert most instances of the first form to the second form. Requested by Chris. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@96344 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-15Uniformize the names of type predicates: rather than having isFloatTy andDuncan Sands
isInteger, we now have isFloatTy and isIntegerTy. Requested by Chris! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@96223 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-12Add support for a union type in LLVM IR. Patch by Talin!Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@96011 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-12Add a new function attribute, 'alignstack'. It will indicate (when the backendsCharles Davis
implement support for it) that the stack should be forcibly realigned in the prologue (and the process reversed in the epilogue). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@95945 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-06Reintroduce the InlineHint function attribute.Jakob Stoklund Olesen
This time it's for real! I am going to hook this up in the frontends as well. The inliner has some experimental heuristics for dealing with the inline hint. When given a -respect-inlinehint option, functions marked with the inline keyword are given a threshold just above the default for -O3. We need some experiments to determine if that is the right thing to do. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@95466 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-27Kill ModuleProvider and ghost linkage by inverting the relationship betweenJeffrey Yasskin
Modules and ModuleProviders. Because the "ModuleProvider" simply materializes GlobalValues now, and doesn't provide modules, it's renamed to "GVMaterializer". Code that used to need a ModuleProvider to materialize Functions can now materialize the Functions directly. Functions no longer use a magic linkage to record that they're materializable; they simply ask the GVMaterializer. Because the C ABI must never change, we can't remove LLVMModuleProviderRef or the functions that refer to it. Instead, because Module now exposes the same functionality ModuleProvider used to, we store a Module* in any LLVMModuleProviderRef and translate in the wrapper methods. The bindings to other languages still use the ModuleProvider concept. It would probably be worth some time to update them to follow the C++ more closely, but I don't intend to do it. Fixes http://llvm.org/PR5737 and http://llvm.org/PR5735. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94686 91177308-0d34-0410-b5e6-96231b3b80d8

2009-12-30now that instruction metadata is only parsed in one place, eliminate theChris Lattner

2009-12-30rename ParseOptionalCustomMetadata -> ParseInstructionMetadata,Chris Lattner

2009-12-30rename lltok::Metadata -> lltok::exclaim. We name tokens Chris Lattner

2009-12-29change ParseMDString and ParseMDNode to take arguments of the right type.Chris Lattner
This exposed a raft of other problems, which I'll deal with in subsequent patches. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@92273 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-29switch to TrackingVH instead of WeakVH, since these can neverChris Lattner
be RAUW'd and go to null. This also gets us some sorely lacking type safety. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@92272 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-29Each instruction is allowed to have *multiple* different Chris Lattner
metadata objects on them. Though the entire compiler supports this, the asmparser didn't. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@92270 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-29Final step in the metadata API restructuring: move the Chris Lattner
getMDKindID/getMDKindNames methods to LLVMContext (and add convenience methods to Module), eliminating MetadataContext. Move the state that it maintains out to LLVMContext. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@92259 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-28This is a major cleanup of the instruction metadata interfaces thatChris Lattner
I asked Devang to do back on Sep 27. Instead of going through the MetadataContext class with methods like getMD() and getMDs(), just ask the instruction directly for its metadata with getMetadata() and getAllMetadata(). This includes a variety of other fixes and improvements: previously all Value*'s were bloated because the HasMetadata bit was thrown into value, adding a 9th bit to a byte. Now this is properly sunk down to the Instruction class (the only place where it makes sense) and it will be folded away somewhere soon. This also fixes some confusion in getMDs and its clients about whether the returned list is indexed by the MDID or densely packed. This is now returned sorted and densely packed and the comments make this clear. This introduces a number of fixme's which I'll follow up on. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@92235 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-28rename getMDKind -> getMDKindID, make it autoinsert if an MD KindChris Lattner
doesn't exist already, eliminate registerMDKind. Tidy up a bunch of random stuff. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@92225 91177308-0d34-0410-b5e6-96231b3b80d8
