JF Bastien	50c9e6310e	[MergeFuncs] Fix callsite attributes in thunk generation ... This change correctly sets the attributes on the callsites generated in thunks. This makes sure things such as sret, sext, etc. are correctly set, so that the call can be a proper tailcall. Also, the transfer of attributes in the replaceDirectCallers function appears to be unnecessary, but until this is confirmed it will remain.

Arnold Schwaighofer	a5aae48d17	MergeFunc: Transfer the callee's attributes when replacing a direct caller ... We insert a bitcast which obfuscates the getCalledFunction for the utility function which looks up attributes from the called function. Loosing ABI changing parameter attributes is a bad thing. rdar://21516488 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@242807 91177308-0d34-0410-b5e6-96231b3b80d8	2015-07-21 17:07:07 +00:00
