Nick Lewycky	7b093a1c2f	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. llvm-svn: 185735	2013-07-06 00:29:58 +00:00
Meador Inge	30024047b3	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	2013-03-21 00:55:59 +00:00
