Dan Gohman 2140a74979 Eliminate the restriction that the array size in an alloca must be i32. 
This will help reduce the amount of casting required on 64-bit targets.

Anton Korobeynikov 8f35fabbc1 Add support for thiscall calling convention.

Dan Gohman a2414ea190 Remove the API compatibility layer which converted add, sub, and mul 
to fadd, fsub, and fmul, when used with a floating-point type. LLVM
has supported the new instructions since 2.6, so it's time to get
on board.

Chris Lattner 95b0ff445c reject invalid comma stuff with a message. We reject the case in 
PR6888 with:

$ llvm-as t.ll
llvm-as: t.ll:2:29: error: expected metadata or 'align'
 store <3 x i32> %x, i32 1, i32 1>, <3 x i32>* %p

instead of:

Chris Lattner c239eb79bd reapply 'reject forward references to functions whose type don't match' 
now that the testsuite has been updated.

Chris Lattner 5a44950aae reject forward references to functions whose type don't match 
up with the definition (and fix a broken testcase).  PR6491.

Chris Lattner f60b74806f turn an assert into a proper check, fixing crash on invalid here: 
$ llvm-as t.ll
llvm-as: t.ll:1:6: error: expected 'type' after '='
%0 = = type { i32, float, float, double }
     ^

PR6810.

Chris Lattner 2e664bd915 fix a crash on invalid metadata, e.g.: call i32 @foo(), XXXX 
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.

Chris Lattner 8eff0157b2 rewrite handling of forward ref'd instruction metadata 
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.

Duncan Sands cbd43f89ac Introduce isOpaqueTy and use it rather than isa<OpaqueType>. Also, move some 
methods to try to have the type predicates be more logically positioned.

llvm-svn: 96349
 2010-02-16 14:50:09 +00:00
Duncan Sands 19d0b47b1f There are two ways of checking for a given type, for example isa<PointerType>(T) 
and T->isPointerTy().  Convert most instances of the first form to the second form.
Requested by Chris.

Duncan Sands 9dff9bec31 Uniformize the names of type predicates: rather than having isFloatTy and 
isInteger, we now have isFloatTy and isIntegerTy.  Requested by Chris!

Chris Lattner 392be58cad Add support for a union type in LLVM IR. Patch by Talin!

Charles Davis be5557e86b Add a new function attribute, 'alignstack'. It will indicate (when the backends 
implement support for it) that the stack should be forcibly realigned in the
prologue (and the process reversed in the epilogue).

 2010-02-12 00:31:15 +00:00
Jakob Stoklund Olesen 74bb06c0f0 Reintroduce the InlineHint function attribute. 
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.

Jeffrey Yasskin 091217be6f Kill ModuleProvider and ghost linkage by inverting the relationship between 
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.

Chris Lattner 94b9c5a73b now that instruction metadata is only parsed in one place, eliminate the 
parser-global MDsOnInst vector and make ParseInstructionMetadata return
its result by-ref through an argument like the entire rest of the parser.

Chris Lattner b2f3950da7 reimplement ParseOptionalInfo as ParseOptionalCommaAlign, correctly 
handle the comma case for metadata.

 2009-12-30 05:44:30 +00:00
Chris Lattner 5c42763452 rename ParseOptionalCustomMetadata -> ParseInstructionMetadata, 
and make it non-optional.  This fixes the bug where we'd accept
and ignore a spurious comma after some instructions.

Chris Lattner eafe4de021 rename NamedOrCustomMD -> MetadataVar to follow conventions of all the rest of the code.

 2009-12-30 05:02:06 +00:00
Chris Lattner 1eed2d65c0 rename lltok::Metadata -> lltok::exclaim. We name tokens 
after their syntactic form, not their semantic form.

llvm-svn: 92294
 2009-12-30 04:56:59 +00:00
Chris Lattner fc58af26d5 rename MetadataCache -> NumberedMetadata to follow the convention 
used by other things.  Convert it to a vector since it is a dense 
numbering.

Chris Lattner a01ddfc2a3 rewrite ParseMDNodeVector to follow the normal patter used in the .ll parser.

 2009-12-30 04:42:57 +00:00
Chris Lattner 6dac02a4f7 rename ParseMDNode -> ParseMDNodeID, since it parses !42, not !{... } as you'd expect.

 2009-12-29 22:01:50 +00:00
Chris Lattner 1797fc7009 change ParseMDString and ParseMDNode to take arguments of the right type. 
This exposed a raft of other problems, which I'll deal with in subsequent
patches.

 2009-12-29 21:53:55 +00:00
Chris Lattner 218b22f33b switch to TrackingVH instead of WeakVH, since these can never 
be RAUW'd and go to null.  This also gets us some sorely lacking
type safety.
