zero-extended to 64 bits. This information is currently provided to the back end by setting "signext" or "zeroext" attributes. However, this is done only for integer types *smaller* than i32, not for i32 itself. This causes clang to generate code violating the ABI, which results in a failure of the tramp3d-v4 test case (due to calling a system library routine without ABI-required extension). This patch implements custom versions of classifyArgumentType and classifyReturnType for PPC64_SVR4_ABIInfo, which are the same as the default versions except that they also classify "int" and "unsigned int" as types needing extending. This fixed tramp3d-v4 on PowerPC64. llvm-svn: 167393
