2012-12-21Revert r170806, "Fix some bugs where we would sometimes use 0, not -1, when ↵NAKAMURA Takumi
emitting a null constant of type pointer-to-data-member." It broke stage2. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@170835 91177308-0d34-0410-b5e6-96231b3b80d8

constant of type pointer-to-data-member. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@170806 91177308-0d34-0410-b5e6-96231b3b80d8
2012-12-04Sort all of Clang's files under 'lib', and fix up the broken headersChandler Carruth
uncovered. This required manually correcting all of the incorrect main-module headers I could find, and running the new llvm/utils/sort_includes.py script over the files. I also manually added quite a few missing headers that were uncovered by shuffling the order or moving headers up to be main-module-headers. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@169237 91177308-0d34-0410-b5e6-96231b3b80d8

2012-11-15Make -ffp-contract a codegen option, rather than a laguage option. This makesLang Hames
more sense anyway - it determines how expressions are codegen'd. It also ensures that -ffp-contract=fast has the intended effect when compiling LLVM IR. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@168027 91177308-0d34-0410-b5e6-96231b3b80d8

2012-11-05Use the individual -fsanitize=<...> arguments to control which of the UBSanRichard Smith
checks to enable. Remove frontend support for -fcatch-undefined-behavior, -faddress-sanitizer and -fthread-sanitizer now that they don't do anything. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@167413 91177308-0d34-0410-b5e6-96231b3b80d8

2012-11-01Split emission of -ftrapv checks and -fcatch-undefined-behavior checks intoRichard Smith
separate functions, since they share essentially no code. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@167259 91177308-0d34-0410-b5e6-96231b3b80d8
2012-11-01Remove divison-by-zero checks from -ftrapv. These checks were incompatible withRichard Smith
g++'s -ftrapv, failed to call the -ftrapv overflow handler, and are still available under -fcatch-undefined-behavior. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@167258 91177308-0d34-0410-b5e6-96231b3b80d8

2012-10-02Add FP_CONTRACT support for clang.Lang Hames
Clang will now honor the FP_CONTRACT pragma and emit LLVM fmuladd intrinsics for expressions of the form A * B + C (when they occur in a single statement). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@164989 91177308-0d34-0410-b5e6-96231b3b80d8
2012-09-08-fcatch-undefined-behavior: Factor emission of the creation of, and branch to,Richard Smith
the trap BB out of the individual checks and into a common function, to prepare for making this code call into a runtime library. Rename the existing EmitCheck to EmitTypeCheck to clarify it and to move it out of the way of the new EmitCheck. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@163451 91177308-0d34-0410-b5e6-96231b3b80d8
2012-08-31Change the representation of builtin functions in the ASTEli Friedman
(__builtin_* etc.) so that it isn't possible to take their address. Specifically, introduce a new type to represent a reference to a builtin function, and a new cast kind to convert it to a function pointer in the operand of a call. Fixes PR13195. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@162962 91177308-0d34-0410-b5e6-96231b3b80d8

2012-08-25-fcatch-undefined-behavior: add the -ftrapv checks to the set of things caughtRichard Smith
by this mode, and also check for signed left shift overflow. The rules for the latter are a little subtle: * neither C89 nor C++98 specify the behavior of a signed left shift at all * in C99 and C11, shifting a 1 bit into the sign bit has undefined behavior * in C++11, with core issue 1457, shifting a 1 bit *out* of the sign bit has undefined behavior As of this change, we use the C99 rules for all C language variants, and the C++11 rules for all C++ language variants. Once we have individual -fcatch-undefined-behavior= flags, this should be revisited. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@162634 91177308-0d34-0410-b5e6-96231b3b80d8
2012-08-24New -fcatch-undefined-behavior features:Richard Smith

2012-06-06Revert Decl's iterators back to pointer value_type rather than reference ↵David Blaikie
value_type In addition, I've made the pointer and reference typedef 'void' rather than T* just so they can't get misused. I would've omitted them entirely but std::distance likes them to be there even if it doesn't use them. This rolls back r155808 and r155869. Review by Doug Gregor incorporating feedback from Chandler Carruth. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@158104 91177308-0d34-0410-b5e6-96231b3b80d8

2012-04-30Remove the ref/value inconsistency in filter_decl_iterator.David Blaikie
filter_decl_iterator had a weird mismatch where both op* and op-> returned T* making it difficult to generalize this filtering behavior into a reusable library of any kind. This change errs on the side of value, making op-> return T* and op* return T&.

we correctly emit loads of BlockDeclRefExprs even when they don't qualify as ODR-uses. I think I'm adequately convinced that BlockDeclRefExpr can die. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@152479 91177308-0d34-0410-b5e6-96231b3b80d8

2012-03-06Add clang support for new Objective-C literal syntax for NSDictionary, NSArray,Ted Kremenek
NSNumber, and boolean literals. This includes both Sema and Codegen support. Included is also support for new Objective-C container subscripting. My apologies for the large patch. It was very difficult to break apart. The patch introduces changes to the driver as well to cause clang to link in additional runtime support when needed to support the new language features. Docs are forthcoming to document the implementation and behavior of these features. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@152137 91177308-0d34-0410-b5e6-96231b3b80d8

2012-02-22Generate an AST for the conversion from a lambda closure type to aDouglas Gregor
block pointer that returns a block literal which captures (by copy) the lambda closure itself. Some aspects of the block literal are left unspecified, namely the capture variable (which doesn't actually exist) and the body (which will be filled in by IRgen because it can't be written as an AST). Because we're switching to this model, this patch also eliminates tracking the copy-initialization expression for the block capture of the conversion function, since that information is now embedded in the synthesized block literal. -1 side tables FTW. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@151131 91177308-0d34-0410-b5e6-96231b3b80d8
