GCC with hard float ABI returns the structure in s0 and s1. There are two things broken in the code generated by TCC: First of all TCC thinks it has to return the structure in memory pointed to by r0 and second it gets confused about where it stored r0 and instead reads the first float from the stack and interpretes that as a pointer. And I am not happy that is_fconst() apparently does not work.
