gcc versions earlier than gcc 6.x fail to build assimp on SuperH when static linking: AssxmlExporter.cpp:623:1: error: unable to find a register to spill in class 'GENERAL_REGS' It's the combination of -Os and *not* having -fPIC that makes gcc fail, which explains why configurations with dynamic linking work fine. -Os -fPIC -> works -Os -> fails -O2 -fPIC -> works -O2 -> works Therefore, as a workaround, we are forcing the use of -O2 on SuperH when the gcc version is older than gcc 6.x and we're statically linking.
