2010-09-02Revert my two IRgen fixes for "bool", then use a far simpler approachDouglas Gregor
based on ConvertTypeForMem. Thanks to John for pointing out the right solution. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@112838 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-02Another i1 vs. i8 type mismatch issue. This timeFariborz Jahanian
a 'bool' byref variable in memory. Fixes radar 8382559. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@112835 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-02Use the unmangled name for the display name in Objective-C debug info. This ↵David Chisnall
should have no effect with the Mac runtime where clang (unlike GCC) uses the display name symbol name. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@112833 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-02Fix more i1/i8 pointer madness. Here, an overactive assertionDouglas Gregor
complains when the element type of a C++ "delete" expression is different from what we would expect from the pointer type. When deleting a bool*, we end up with an i1 on one side (where we compute the LLVM type from the Clang bool type) and i8 on the other (where we grab the LLVM type from the LLVM pointer type). I've weakened the assertion appropriately, and the Boost Parallel Graph Library now passes its regression tests. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@112821 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-02Fix a crash involving pointer-to-data-members of boolean type. We wereDouglas Gregor
constructing an LLVM PointerType directly from the "bool"'s LLVM type (i1), which resulted in unfortunate pointer type i1*. The fix is to build the LLVM PointerType from the corresponding Clang PointerType, so that we get i8* in the case of a bool. John, please review. I also left a FIXME there because we seem to be dropping "volatile", which would be rather unfortunate. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@112819 91177308-0d34-0410-b5e6-96231b3b80d8

2010-09-02Abstract IR generation of array cookies into the C++ ABI class andJohn McCall
implement ARM array cookies. Also fix a few unfortunate bugs: - throwing dtors in deletes prevented the allocation from being deleted - adding the cookie to the new[] size was not being considered for overflow (and, more seriously, was screwing up the earlier checks) - deleting an array via a pointer to array of class type was not causing any destructors to be run and was passing the unadjusted pointer to the deallocator - lots of address-space problems, in case anyone wants to support free store in a variant address space :) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@112814 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-01Translate NEON vmull, vmlal, and vmlsl builtins to llvm multiply-add/subBob Wilson
with zext/sext operations, instead of to llvm intrinsics. I have a plan to avoid the clang builtins for these, but it is going to take a little longer and I want to get the NEON intrinsics updated before the 2.8 release. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@112764 91177308-0d34-0410-b5e6-96231b3b80d8

2010-09-01Split ObjCInterfaceDecl::ReferencedProtocols into two lists: ↵Ted Kremenek
ReferencedProtocols and AllReferencedProtocols. ReferencedProtocols (and thus protocol_begin(), protocol_end()) now only contains the list of protocols that were directly referenced in an @interface declaration. 'all_referenced_protocol_[begin,end]()' now returns the set of protocols that were referenced in both the @interface and class extensions. The latter is needed for semantic analysis/codegen, while the former is needed to maintain the lexical information of the original source. Fixes <rdar://problem/8380046>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@112691 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-01fix rdar://8360877 a really nasty miscompilation in Boost.XpressiveChris Lattner
caused by my ABI work. Passing: struct outer { int x; struct epsilon_matcher {} e; int f; }; as {i32,i32} isn't safe, because the offset of the second element needs to be at 8 when it is interpreted as a memory value. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@112686 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

2010-08-25Finally 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
