I am using the version included in Oracle Studio 12.6, and it seems that it always emit a EM_SPARC32PLUS type for 32-bit objects. The documentation for the -xarch also states that even when using the most generic target (`sparc`), it only supports emitting for V9 ISA (that is, EM_SPARC32PLUS for 32-bit target): > sparc > Compile for the SPARC-V9 ISA. > Compile for the V9 ISA, but without the Visual Instruction Set (VIS), > and without other implementation-specific ISA extensions.
