hi reames, I have a question in the view of customer. If he writes deliberately to a read-only memory to expect trigger a seg fault, or if he wants to write to a memory which he does not realize it is read only. Should compiler tell him the writing is invalid, rather than treat it as a nop silently?

@RKSimon @craig.topper , could you please review again?

@RKSimon , @craig.topper , I updated it. Please review again.

@RKSimon I add doxygen based descriptions in header files and return type check in test files. Please review again.

Sorry about that. Have you sync'd to head? I thought that was fixed with r358745 (from Bjorn Pettersson).

hi sammccall, when I run "check-all", some waring/error print out in STLExtrasTest.cpp as follow. My version is llvm:0ee120077 and clang:d87ee8e678. Could you please fix it or guide me how to fix it?
