[llvm-commits] [PATCH] Suppress "user-defined return type in extern C" warning under Clang

[Matt Johnson]

The attached patch suppresses warnings in 
lib/ExecutionEngine/Interpreter/ExternalFunctions.cpp of the flavor:

ExternalFunctions.cpp:308:14: warning: 'lle_X_atexit' has C-linkage 
specified, but returns user-defined type 'llvm::GenericValue' which is 
incompatible with C [-Wreturn-type]
GenericValue lle_X_atexit(FunctionType *FT,

under clang.  The suppression was already done for Visual Studio.  I 
couldn't immediately find other examples of such warning suppression to 
know the preferred way to do it for clang, so I used push/pop to only 
ignore the warning for the section of the file that defines lle_X_*() .

Comments welcome.
Thanks!
