* [LibTooling] Add Transformer, a library for source-to-source transformations.Yitzhak Mandelbaum2019-04-052-0/+204
| | | | | | | | | | | | | | | | Summary: Adds a basic version of Transformer, a library supporting the concise specification of clang-based source-to-source transformations. A full discussion of the end goal can be found on the cfe-dev list with subject "[RFC] Easier source-to-source transformations with clang tooling".

* [LibTooling] Add "SourceCode" library for functions relating to source-code ↵Yitzhak Mandelbaum2019-04-053-9/+32
| | | | | | | | | | | | | | | | | | | | | | | | | manipulation. Summary: Introduces a utility library in Refactoring/ to collect routines related to source-code manipulation. In this change, we move "extended-range" functions from the FixIt library (in clangTooling) to this new library. We need to use this functionality in Refactoring/ and cannot access it if it resides in Tooling/, because that would cause clangToolingRefactor to depend on clangTooling, which would be a circular dependency.

* Make SourceManager::createFileID(UnownedTag, ...) take a const ↵Nico Weber2019-04-046-22/+25
| | | | | | | | | | | | | | | | | | | | | llvm::MemoryBuffer* Requires making the llvm::MemoryBuffer* stored by SourceManager const, which in turn requires making the accessors for that return const llvm::MemoryBuffer*s and updating all call sites. The original motivation for this was to use it and fix the TODO in CodeGenAction.cpp's ConvertBackendLocation() by using the UnownedTag version of createFileID, and since llvm::SourceMgr* hands out a const llvm::MemoryBuffer* this is required. I'm not sure if fixing the TODO this way actually works, but this seems like a good change on its own anyways. No intended behavior change.

| | | | | | | | | | | | | | | | | | | Summary: The fix isn't great, but it's hard to fix properly because the completion code sensibly uses ParmVarDecl to represent parameters, but the AST-building code sensibly doesn't synthesize them if the type is broken. Also this case is apparently really rare, so it's probably not worth bending over backwards for.

* [analyzer] When failing to evaluate a __builtin_constant_p, presume it's false.Artem Dergachev2019-04-031-1/+9
| | | | | | | | | | | | | | | | | | | | | __builtin_constant_p(x) is a compiler builtin that evaluates to 1 when its argument x is a compile-time constant and to 0 otherwise. In CodeGen it is simply lowered to the respective LLVM intrinsic. In the Analyzer we've been trying to delegate modeling to Expr::EvaluateAsInt, which is allowed to sometimes fail for no apparent reason. When it fails, let's conservatively return false. Modeling it as false is pretty much never wrong, and it is only required to return true on a best-effort basis, which every user should expect. Fixes VLAChecker false positives on code that tries to emulate static asserts in C by constructing a VLA of dynamic size -1 under the assumption that this dynamic size is actually a constant in the sense of __builtin_constant_p.

Also define small_printf optimizations, which is a printf with float support but not long double (which in wasm can be useful since long doubles are 128 bit and force linking of float128 emulation code). This part is based on sunfish's https://reviews.llvm.org/D57620 (which can't land yet since the WASI integration isn't ready yet).

* [Sema] Fix a use-after-deallocate of a ParsedAttrErik Pilkington2019-04-021-2/+2
| | | | | | | | | | | | | | | moveAttrFromListToList only makes sense when moving an attribute to a list with a pool that's either equivalent, or has a shorter lifetime. Therefore, using it to move a ParsedAttr from a declarator to a declaration specifier doesn't make sense, since the declaration specifier's pool outlives the declarator's. The patch adds a new function, ParsedAttributes::takeOneFrom, which transfers the attribute from one pool to another, fixing the use-after-deallocate. rdar://49175426 Differential revision: https://reviews.llvm.org/D60101 llvm-svn: 357516

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | transformation. Before this patch, CGLoop would dump all transformations for a loop into a single LoopID without encoding any order in which to apply them. rL348944 added the possibility to encode a transformation order using followup-attributes. When a loop has more than one transformation, use the follow-up attribute define the order in which they are applied. The emitted order is the defacto order as defined by the current LLVM pass pipeline, which is: LoopFullUnrollPass LoopDistributePass LoopVectorizePass LoopUnrollAndJamPass LoopUnrollPass MachinePipeliner This patch should therefore not change the assembly output, assuming that all explicit transformations can be applied, and no implicit transformations in-between. In the former case, WarnMissedTransformationsPass should emit a warning (except for MachinePipeliner which is not implemented yet). The latter could be avoided by adding 'llvm.loop.disable_nonforced' attributes. Because LoopUnrollAndJamPass processes a loop nest, generation of the MDNode is delayed to after the inner loop metadata have been processed. A temporary LoopID is therefore used to annotate instructions and RAUW'ed by the actual LoopID later. Differential Revision: https://reviews.llvm.org/D57978 llvm-svn: 357415
