What is different this time (besides the apparent difficulty to build a > new toolchain) ? Or am I missing something ? sh4-linux-gcc doesn't recognize -m2a-nofpu, so that is not passed. It does recognize -m4a-nofpu, but when that's passed, it complains about opcode not valid for this cpu variant in inline asm/ Ah, it also recognizes -m4-nofpu. If I add that, se7206_defconfig builds. I assume a proper sh2a-linux toolchain will not recognize the -m4-nofpu, so it won't be passed due to $(call cc-option). Does this sound like an acceptable solution? If yes, I'll send a patch.
