2010-08-31Rename DeclContext::getLookupContext to getRedeclContext and change its ↵Sebastian Redl
semantics slightly. No functionality change in the absence of inline namespaces. Also, change a few places where inline namespaces actually make a difference to be prepared for them. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@112563 91177308-0d34-0410-b5e6-96231b3b80d8

2010-08-30Two minor fixes to user-defined literals:Sean Hunt
- Zero-initialize UDLData so that crashes stop - Stop complaining that we can't emit them (we most certainly can) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@112467 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-29Implement C++0x user-defined string literals.Sean Hunt
The extra data stored on user-defined literal Tokens is stored in extra allocated memory, which is managed by the PreprocessorLexer because there isn't a better place to put it that makes sure it gets deallocated, but only after it's used up. My testing has shown no significant slowdown as a result, but independent testing would be appreciated. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@112458 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-29Translate NEON vaddl, vaddw, vsubl, and vsubw builtins to llvm add/subBob Wilson
with zext/sext operations, instead of to llvm intrinsics. (We can also get rid of the clang builtins and handle these entirely in the arm_neon.h header if there is a way to express vector sext/zext in C.) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@112413 91177308-0d34-0410-b5e6-96231b3b80d8

2010-08-26fix 2xi16 to pass as i32 instead of <2 x i16>. The former passes inChris Lattner

2010-08-25Finally pass "two floats in a 64-bit unit" as a <2 x float> instead ofChris Lattner
as a double in the x86-64 ABI. This allows us to generate much better code for certain things, e.g.: _Complex float f32(_Complex float A, _Complex float B) { return A+B; } Used to compile into (look at the integer silliness!): _f32: ## @f32 ## BB#0: ## %entry movd %xmm1, %rax movd %eax, %xmm1 movd %xmm0, %rcx movd %ecx, %xmm0 addss %xmm1, %xmm0 movd %xmm0, %edx shrq $32, %rax movd %eax, %xmm0 shrq $32, %rcx movd %ecx, %xmm1 addss %xmm0, %xmm1 movd %xmm1, %eax shlq $32, %rax addq %rdx, %rax movd %rax, %xmm0 ret Now we get: _f32: ## @f32 movdqa %xmm0, %xmm2 addss %xmm1, %xmm2 pshufd $16, %xmm2, %xmm2 pshufd $1, %xmm1, %xmm1 pshufd $1, %xmm0, %xmm0 addss %xmm1, %xmm0 pshufd $16, %xmm0, %xmm1 movdqa %xmm2, %xmm0 unpcklps %xmm1, %xmm0 ret and compile stuff like: extern float _Complex ccoshf( float _Complex ) ; float _Complex ccosf ( float _Complex z ) { float _Complex iz; (__real__ iz) = -(__imag__ z); (__imag__ iz) = (__real__ z); return ccoshf(iz); } into: _ccosf: ## @ccosf ## BB#0: ## %entry pshufd $1, %xmm0, %xmm1 xorps LCPI4_0(%rip), %xmm1 unpcklps %xmm0, %xmm1 movaps %xmm1, %xmm0 jmp _ccoshf ## TAILCALL instead of: _ccosf: ## @ccosf ## BB#0: ## %entry movd %xmm0, %rax movq %rax, %rcx shlq $32, %rcx shrq $32, %rax xorl $-2147483648, %eax ## imm = 0xFFFFFFFF80000000 addq %rcx, %rax movd %rax, %xmm0 jmp _ccoshf ## TAILCALL There is still "stuff to be done" here for the struct case, but this resolves rdar://6379669 - [x86-64 ABI] Pass and return _Complex float / double efficiently git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@112111 91177308-0d34-0410-b5e6-96231b3b80d8

2010-08-25IRgen: Fix a horrible bug in pointer to bool conversion, which we were treatingDaniel Dunbar
as a truncation not a comparison to null. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@112021 91177308-0d34-0410-b5e6-96231b3b80d8

but not in C++, so don't emit aggregate loads of volatile references in null context in C++. Happens to have been caught by an assertion. We do not get the scalar case right. Volatiles are really broken. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@112019 91177308-0d34-0410-b5e6-96231b3b80d8

2010-08-23fix rdar://8340348, a miscompile of boost that was exposed by r109848.Chris Lattner
That revision started classifying truly empty structs like "Y" and "X" as being NoClass/NoClass and turning them into 'ignore'. The call code turns around and allocates space for the ignored argument with GetUndefRValue. The bug is that GetUndefRValue would return the address as undef, instead of returning an object with a defined address but undefined contents. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@111794 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-23Abstract out everything having to do with member pointers into the ABIJohn McCall
class; they should just be completely opaque throughout IR gen now, although I haven't really audited that. Fix a bug apparently inherited from gcc-4.2 where we failed to null-check member data pointers when performing derived-to-base or base-to-derived conversions on them. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@111789 91177308-0d34-0410-b5e6-96231b3b80d8

2010-08-22Go back to asking CodeGenTypes whether a type is zero-initializable.John McCall
Make CGT defer to the ABI on all member pointer types. This requires giving CGT a handle to the ABI. It's way easier to make that work if we avoid lazily creating the ABI. Make it so. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@111786 91177308-0d34-0410-b5e6-96231b3b80d8

2010-08-22When performing value-initialization for a class with a non-trivial,Douglas Gregor
implicitly-defined default constructor, zero-initialize the memory before calling the default constructor. Previously, we would only zero-initialize in the case of a trivial default constructor. Also, simplify the hideous logic that determines when we have a trivial default constructor and, therefore, don't need to emit any call at all. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@111779 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-22Clean up a very silly use of first-class aggregates.John McCall
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@111777 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-22Experiment with using first-class aggregates to represent member functionJohn McCall
pointers. I find the resulting code to be substantially cleaner, and it makes it very easy to use the same APIs for data member pointers (which I have conscientiously avoided here), and it avoids a plethora of potential inefficiencies due to excessive memory copying, but we'll have to see if it actually works. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@111776 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-22Extract member function pointer comparison and null comparison intoJohn McCall
the ABI code. Implement correct semantics for these on ARM. I believe this completes the implementation of member function pointers on ARM. I think I'm going to switch member function pointers over to be non-aggregates while I have all this in mind. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@111774 91177308-0d34-0410-b5e6-96231b3b80d8
