+/* MIPS assembler and ARM->MIPS assembly translator
+**
+** The approach is to leave the GGLAssembler and associated files largely
+** un-changed, still utilizing all Arm instruction generation. Via the
+** ArmToMipsAssembler (subclassed from ArmAssemblerInterface) each Arm
+** instruction is translated to one or more Mips instructions as necessary. This
+** is clearly less efficient than a direct implementation within the
+** GGLAssembler, but is far cleaner, more maintainable, and has yielded very
+** significant performance gains on Mips compared to the generic pixel pipeline.
+**
+**
+** GGLAssembler changes
+**
+** - The register allocator has been modified to re-map Arm registers 0-15 to mips
+** registers 2-17. Mips register 0 cannot be used as general-purpose register,
+** and register 1 has traditional uses as a short-term temporary.
+**
+** - Added some early bailouts for OUT_OF_REGISTERS in texturing.cpp and
+** GGLAssembler.cpp, since this is not fatal, and can be retried at lower
+** optimization level.
+**
+**
+** ARMAssembler and ARMAssemblerInterface changes
+**
+** Refactored ARM address-mode static functions (imm(), reg_imm(), imm12_pre(), etc.)
+** to virtual, so they can be overridden in MIPSAssembler. The implementation of these
+** functions on ARM is moved from ARMAssemblerInterface.cpp to ARMAssembler.cpp, and
+** is unchanged from the original. (This required duplicating 2 of these as static
+** functions in ARMAssemblerInterface.cpp so they could be used as static initializers).
