When analyzing functions known to only access argument pointees, only check arguments with pointer types. Update the documentation of IntrReadArgMem reflect this. While here, add support for TBAA tags on intrinsic calls. llvm-svn: 130317

AA: Use generic intrinsics for tests instead of target specific ones Update a few tests to use llvm.masked.load/store instead of arm neon vector loads and stores, and move the tests that are actually specific to those arm intrinsics to their own files. This lets us mark the tests that use target specific intrinsics as requiring those targets. llvm-svn: 302972

Modify the LLVM assembly output so that it uses references to represent function attributes. This makes the LLVM assembly look better. E.g.: define void @foo() #0 { ret void } attributes #0 = { nounwind noinline ssp } llvm-svn: 175605

[FunctionAttrs] Annotate "willreturn" for intrinsics Summary: In D62801, new function attribute `willreturn` was introduced. In short, a function with `willreturn` is guaranteed to come back to the call site(more precise definition is in LangRef). In this patch, willreturn is annotated for LLVM intrinsics.

Use references to attribute groups on the call/invoke instructions. Listing all of the attributes for the callee of a call/invoke instruction is way too much and makes the IR unreadable. Use references to attributes instead. llvm-svn: 175877
