* Introduce Type::isSignedIntegerOrEnumerationType() andDouglas Gregor2011-05-201-2/+2
| | | | | | | | | | | | | Type::isUnsignedIntegerOrEnumerationType(), which are like Type::isSignedIntegerType() and Type::isUnsignedIntegerType() but also consider the underlying type of a C++0x scoped enumeration type. Audited all callers to the existing functions, switching those that need to also handle scoped enumeration types (e.g., those that deal with constant values) over to the new functions. Fixes PR9923 / <rdar://problem/9447851>. llvm-svn: 131735
* For calls returning first-class aggregates, store by element instead of ↵Eli Friedman2011-05-171-2/+25

| | | | | | rdar://problem/8139919 . This shouldn't make much of a difference at -O3, but should substantially reduce the number of generated memcpy's at -O0. llvm-svn: 130717
* Switch CallArgList from an std::pair to a new CallArg struct (which will ↵Eli Friedman2011-05-021-10/+9

* Implement ARM pcs attribute. Basically it's another way of calling ↵Anton Korobeynikov2011-04-141-0/+5
| | | | | | | | | | convention selection (AAPCS or AAPCS+VFP), similar to fastcall / stdcall / whatevercall seen on x86. In particular, all library functions should always be AAPCS regardless of floating point ABI used. llvm-svn: 129534
* PR8369: make __attribute((regparm(0))) work correctly. Original patch byEli Friedman2011-04-091-5/+8
| | | | | | pageexec@freemail.hu, tweaks by me. llvm-svn: 129206
* Add support for language-specific address spaces. On top of that,Peter Collingbourne2011-03-181-1/+2
| | | | | | | | | add support for the OpenCL __private, __local, __constant and __global address spaces, as well as the __read_only, _read_write and __write_only image access specifiers. Patch originally by ARM; language-specific address space support by myself. llvm-svn: 127915
* Instead of storing an ASTContext* in FunctionProtoTypes with computed ↵Sebastian Redl2011-03-131-1/+1
| | | | | | noexcept specifiers, unique FunctionProtoTypes with a ContextualFoldingSet, as suggested by John McCall. llvm-svn: 127568
* Propagate the new exception information to FunctionProtoType.Sebastian Redl2011-03-121-1/+1
| | | | | | | | Change the interface to expose the new information and deal with the enormous fallout. Introduce the new ExceptionSpecificationType value EST_DynamicNone to more easily deal with empty throw specifications. Update the tests for noexcept and fix the various bugs uncovered, such as lack of tentative parsing support. llvm-svn: 127537

* lib/CodeGen/CGCall.cpp: Don't invoke multiple Builder.CreateBitCast() on ↵NAKAMURA Takumi2011-03-101-2/+4
| | | | | | Builder.CreateMemCpy. Or we would see sideeffect incompatibility among gcc and clang. llvm-svn: 127405
* Use the "undergoes default argument promotion" bit on parameters toJohn McCall2011-03-091-17/+38
| | | | | | | | | | simplify the logic of initializing function parameters so that we don't need both a variable declaration and a type in FunctionArgList. This also means that we need to propagate the CGFunctionInfo down in a lot of places rather than recalculating it from the FAL. There's more we can do to eliminate redundancy here, and I've left FIXMEs behind to do it. llvm-svn: 127314

* objc IRGen for Next runtime message API.Fariborz Jahanian2011-03-011-1/+2
| | | | | | | | | | The prototype for objc_msgSend() is technically variadic - `id objc_msgSend(id, SEL, ...)`. But all method calls should use a prototype that matches the method, not the prototype for objc_msgSend itself(). // rdar://9048030 llvm-svn: 126754

* Add symantic support for the Pascal calling convention viaDawn Perchik2010-09-031-0/+4
| | | | | | | "__attribute((pascal))" or "__pascal" (and "_pascal" under -fborland-extensions). Support still needs to be added to llvm. llvm-svn: 112939

* It's not safe to use the generic CXXMethodDecl overload of CGT::getFunctionInfoJohn McCall2010-09-031-0/+3

* IRgen: Change Emit{Load,Store}OfScalar to take a required Alignment argument andDaniel Dunbar2010-08-211-11/+23
| | | | | | | | update callers as best I can. - This is a work in progress, our alignment handling is very horrible / sketchy -- I am just aiming for monotonic improvement. - Serious review appreciated. llvm-svn: 111707
* fix PR5179 and correctly fix PR5831 to not miscompile.Chris Lattner2010-07-301-9/+47
| | | | | | | | | | | | | | | | | | | | The X86-64 ABI code didn't handle the case when a struct would get classified and turn up as "NoClass INTEGER" for example. This is perfectly possible when the first slot is all padding (e.g. due to empty base classes). In this situation, the first 8-byte doesn't take a register at all, only the second 8-byte does. This fixes this by enhancing the x86-64 abi stuff to allow and handle this case, reverts the broken fix for PR5831, and enhances the target independent stuff to be able to handle an argument value in registers being accessed at an offset from the memory value. This is the last x86-64 calling convention related miscompile that I'm aware of. llvm-svn: 109848
* fix a builder, why didn't clang++ catch this?Chris Lattner2010-07-291-1/+2

* Kill off the 'coerce' ABI passing form. Now 'direct' and 'extend' alwaysChris Lattner2010-07-291-151/+138
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | have a "coerce to" type which often matches the default lowering of Clang type to LLVM IR type, but the coerce case can be handled by making them not be the same. This simplifies things and fixes issues where X86-64 abi lowering would return coerce after making preferred types exactly match up. This caused us to compile: typedef float v4f32 __attribute__((__vector_size__(16))); v4f32 foo(v4f32 X) { return X+X; } into this code at -O0: define <4 x float> @foo(<4 x float> %X.coerce) nounwind { entry: %retval = alloca <4 x float>, align 16 ; <<4 x float>*> [#uses=2] %coerce = alloca <4 x float>, align 16 ; <<4 x float>*> [#uses=2] %X.addr = alloca <4 x float>, align 16 ; <<4 x float>*> [#uses=3] store <4 x float> %X.coerce, <4 x float>* %coerce %X = load <4 x float>* %coerce ; <<4 x float>> [#uses=1] store <4 x float> %X, <4 x float>* %X.addr %tmp = load <4 x float>* %X.addr ; <<4 x float>> [#uses=1] %tmp1 = load <4 x float>* %X.addr ; <<4 x float>> [#uses=1] %add = fadd <4 x float> %tmp, %tmp1 ; <<4 x float>> [#uses=1] store <4 x float> %add, <4 x float>* %retval %0 = load <4 x float>* %retval ; <<4 x float>> [#uses=1] ret <4 x float> %0 } Now we get: define <4 x float> @foo(<4 x float> %X) nounwind { entry: %X.addr = alloca <4 x float>, align 16 ; <<4 x float>*> [#uses=3] store <4 x float> %X, <4 x float>* %X.addr %tmp = load <4 x float>* %X.addr ; <<4 x float>> [#uses=1] %tmp1 = load <4 x float>* %X.addr ; <<4 x float>> [#uses=1] %add = fadd <4 x float> %tmp, %tmp1 ; <<4 x float>> [#uses=1] ret <4 x float> %add } This implements rdar://8248065 llvm-svn: 109733

| | | | | | | | | | | them as such. Type::is(Signed|Unsigned|)IntegerType() now return false for vector types, and new functions has(Signed|Unsigned|)IntegerRepresentation() cover integer types and vector-of-integer types.
