I've recently updated from an early February version of 1.7.0 to Version 1.7.0 Under development (unstable) (2003-03-25) and am now having problems with errors giving the message: ' getExtends(ClassDef) : @ must be used on an object with a formal class' which seems to be caused by 'setIs("character","character or NULL")' which attempts to define 'character' as an extension of the virtual class 'character or NULL' defined in 'setClass(...

...e in the IR is target specific since it already contains some ABI information at this point. I know Mips would use the definition above but other targets may vary. The target hook is classifyArgumentType() and classifyReturnType() in tools/clang/lib/CodeGen/TargetInfo.cpp and returning ABIArgInfo::getExtend() causes the signext/zeroexts to be emitted appropriately for the type. > 2) Does the presence of the signext mean it's imperative to sign > extend, or that extension, only if needed, should be signed? It's an agreement between the caller and callee to ensure the value is sign-exten...

Hello, For a simple function taking a short and returning a short, clang generates IR with this function signature: define signext i16 @foo(i16 signext %x) Some questions please: 1) For the input parameter and return value, does the target control whether clang uses signext vs something else? If so, how does this target query work? 2) Does the presence of the signext mean it's imperative

Thanks for the great help. Should these classify calls be moved down into the ABIInfo base class? They also are not marked virtual yet targets are expected override as needed.
