is required
+* MIPS64
+ * ABI is n64 (LP64)
+ * Big-endian default; little-endian variants also supported
+ * Default ABI variant uses FPU registers; alternate soft-float ABI
+ that does not use FPU registers or instructions is available
+
* PowerPC
* Only 32-bit is supported
* Compiler toolchain must provide 64-bit long double, not IBM
