With specific compiler options selecting the arch like -xarch=sparc on newer compilers like Oracle Studio 12.4 there is no definition of __sparcv8 but __sparcv8plus which means the V9 ISA, but limited to the 32–bit subset defined by the V8plus ISA specification, without the Visual Instruction Set (VIS), and without other implementation-specific ISA extensions. So it should be the same as __sparcv8.

Just for reference here is the current list of predefined macros with the compiler settings which triggered the error. Please note that __sparcv8 is missing but __sparcv8plus is present.
