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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@177619 91177308-0d34-0410-b5e6-96231b3b80d8

; RUN: opt < %s -functionattrs -S | FileCheck %s
Fix FileCheck --check-prefix lines. Various tests had sprung up over the years which had --check-prefix=ABC on the RUN line, but "CHECK-ABC:" later on. This happened to work before, but was strictly incorrect. FileCheck is getting stricter soon though.

Extend 'readonly' and 'readnone' to work on function arguments as well as functions. Make the function attributes pass add it to known library functions and when it can deduce it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@185735 91177308-0d34-0410-b5e6-96231b3b80d8

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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@185502 91177308-0d34-0410-b5e6-96231b3b80d8
