...when we use llvm-gcc for arm-target. Because return type of function pointer p's is struct type T which has one element, llvm-gcc for arm target calls a function which tries to chang aggregate return type to inner element. (For example, C.HandleAggregateResultAsScalar(Ty); --> DefaultABI::HandleReturnType() function gcc/llvm-abi-default.cpp) In this case, infinite recursion is generated. So I made a patch. when function's return type is struct type and this struct type includes only function's pointer type as element, funtion's return type is not struct type's element and is stru...

This does not qualify as "without knowing the internals of the struct" :-) DefaultABI::HandleReturnType made an interesting reading, although it uses information which is unaccessible to my compiler. -- Oscar

Take a look at llvm-gcc. Look for HandleAggregateShadowArgument.

One more testcase, which might be of interest; crashes clang on x86-64: struct T { struct T (*p)(void); } t; -Eli
