2011-03-04Emit a stop point before a call expression so that debugger has some chance ↵Devang Patel
of getting some footing when user wants to stop at 2nd bar() in following expression when all function calls are inlined. = bar() + ... + bar() + ... clang keeps track of column numbers, so we could put location entries for all subexpressions but that will significantly bloat debug info in general, but a location for call expression is helpful here. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@127018 91177308-0d34-0410-b5e6-96231b3b80d8

The prototype for objc_msgSend() is technically variadic - `id objc_msgSend(id, SEL, ...)`.

2011-02-28Add a -fcxx-exceptions flag to the frontend, which can be used to enableAnders Carlsson
C++ exceptions, even when exceptions have been turned off using -fno-exceptions. Make the -fobjc-exceptions flag do the same thing, but for Objective-C exceptions. C++ and Objective-C exceptions can also be disabled using -fno-cxx-excptions and -fno-objc-exceptions. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@126630 91177308-0d34-0410-b5e6-96231b3b80d8

2011-02-28First tiny step to implementing PR9322: build infrastructure for only ↵Chris Lattner
emitting the live case of a switch statement when switching on a constant. This is terribly limited, but enough to handle the trivial example included. Before we would emit: define void @test1(i32 %i) nounwind { entry: %i.addr = alloca i32, align 4 store i32 %i, i32* %i.addr, align 4 switch i32 1, label %sw.epilog [ i32 1, label %sw.bb ] sw.bb: ; preds = %entry %tmp = load i32* %i.addr, align 4 %inc = add nsw i32 %tmp, 1 store i32 %inc, i32* %i.addr, align 4 br label %sw.epilog sw.epilog: ; preds = %sw.bb, %entry switch i32 0, label %sw.epilog3 [ i32 1, label %sw.bb1 ] sw.bb1: ; preds = %sw.epilog %tmp2 = load i32* %i.addr, align 4 %add = add nsw i32 %tmp2, 2 store i32 %add, i32* %i.addr, align 4 br label %sw.epilog3 sw.epilog3: ; preds = %sw.bb1, %sw.epilog ret void } now we emit: define void @test1(i32 %i) nounwind { entry: %i.addr = alloca i32, align 4 store i32 %i, i32* %i.addr, align 4 %tmp = load i32* %i.addr, align 4 %inc = add nsw i32 %tmp, 1 store i32 %inc, i32* %i.addr, align 4 ret void } This improves -O0 compile time (less IR to generate and shove through the code generator) and the clever linux kernel people found a way to fail to build if we don't do this optimization. This step isn't enough to handle the kernel case though. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@126597 91177308-0d34-0410-b5e6-96231b3b80d8

2011-02-26Pretty up the emission of field l-values and use volatile and TBAA whenJohn McCall
loading references as part of that. Use 'char' TBAA when accessing (immediate!) fields of a may_alias struct; fixes PR9307. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@126540 91177308-0d34-0410-b5e6-96231b3b80d8

necessarily enclose the innermost normal cleanup depth, because the top of the jump scope stack might be an EH cleanup or EH scope. Fixes PR9303. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@126472 91177308-0d34-0410-b5e6-96231b3b80d8

2011-02-23Fix type mismatch between property function that CGObjCGNU was returning and ↵David Chisnall
the one CGObjC was calling. Fixes bug r9294. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@126312 91177308-0d34-0410-b5e6-96231b3b80d8
2011-02-22Emit the structure layout of the block literal parameter to a blockJohn McCall
invocation function into the debug info. Rather than faking up a class, which is tricky because of the custom layout we do, we just emit a struct directly from the layout information we've already got. Also, don't emit an unnecessarily parameter alloca for this "variable". git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@126255 91177308-0d34-0410-b5e6-96231b3b80d8
