[TLI] Fix NumParams==0 prototype checking typo. There was a typo in r267758. It caused invalid accesses when given something like "void @free(...)", as NumParams == 0, and we then try to look at the 0th parameter. Turns out, most of these were untested; add both attribute and missing-prototype checks for all libc libfuncs. Differential Revision: http://reviews.llvm.org/D20543 llvm-svn: 270750

[NVPTX] Infer __nvvm_reflect as nounwind, readnone This patch simply mirrors the attributes we give to @llvm.nvvm.reflect to the __nvvm_reflect libdevice call. This shaves about 30% of the code in libdevice away because of CSE opportunities. It's also helps us figure out that libdevice implementations of transcendental functions don't have side-effects. llvm-svn: 265060

Move library call prototype attribute inference to functionattrs The simplify-libcalls pass implemented a doInitialization hook to infer function prototype attributes for well-known functions. Given that the simplify-libcalls pass is going away *and* that the functionattrs pass is already in place to deduce function attributes, I am moving this logic to the functionattrs pass. This approach was discussed during patch review: http://lists.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20121126/157465.html. llvm-svn: 177619

[MemoryBuiltins] Remove isOperatorNewLike by consolidating non-null inference handling This patch removes the isOperatorNewLike predicate since it was only being used to establish a non-null return value and we have attributes specifically for that purpose with generic handling. To keep approximate the same behaviour for existing frontends, I added the various operator new like (i.e. instances of operator new) to InferFunctionAttrs. It's not really clear to me why this isn't handled in Clang, but I didn't want to break existing code and any subtle assumptions it might have. Once this patch is in, I'm going to start separating the isAllocLike family of predicates. These appear to be being used for a mixture of things which should be more clearly separated and documented. Today, they're being used to indicate (at least) aliasing facts, CSE-ability, and default values from an allocation site. Differential Revision: http://reviews.llvm.org/D15820 llvm-svn: 256787

[TLI] Fix NumParams==0 prototype checking typo. There was a typo in r267758. It caused invalid accesses when given something like "void @free(...)", as NumParams == 0, and we then try to look at the 0th parameter. Turns out, most of these were untested; add both attribute and missing-prototype checks for all libc libfuncs. Differential Revision: http://reviews.llvm.org/D20543 llvm-svn: 270750

Add argmononly attribute to strlen and wcslen, i.e. they only read memory (string) passed to them. Summary: This allows strlen to be moved out of the loop in case its argument is not modified in the loop in LICM.

[BasicAA] Remove special casing of memset_pattern16 in favor of generic attribute inference Most of the properties of memset_pattern16 can be now covered by the generic attributes and inferred by InferFunctionAttrs. The only exceptions are: - We don't yet have a writeonly attribute for the first argument. - We don't have an attribute for modeling the access size facts encoded in MemoryLocation.cpp. Differential Revision: http://reviews.llvm.org/D15879 llvm-svn: 256911

Added support in FunctionAttrs for adding relevant function/argument attributes for the posix call gettimeofday. This implies annotating it as nounwind and its arguments as nocapture. To be conservative, we do not annotate the arguments with noalias since some platforms do not have restrict on the declaration for gettimeofday. llvm-svn: 185502

Move library call prototype attribute inference to functionattrs The simplify-libcalls pass implemented a doInitialization hook to infer function prototype attributes for well-known functions. Given that the simplify-libcalls pass is going away *and* that the functionattrs pass is already in place to deduce function attributes, I am moving this logic to the functionattrs pass. This approach was discussed during patch review: http://lists.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20121126/157465.html. llvm-svn: 177619
