According to src/gnu/dist/toolchain/gcc/config/m68k/m68k.h, it seems -m68030 is same with -m[c]68020: --- #define TARGET_SWITCHES \ { { "68020", - (MASK_5200|MASK_68060|MASK_68040|MASK_68040_ONLY)}, \ { "c68020", - (MASK_5200|MASK_68060|MASK_68040|MASK_68040_ONLY)}, \ { "68020", (MASK_68020|MASK_BITFIELD)}, \ { "c68020", (MASK_68020|MASK_BITFIELD)}, \ : { "68030", - (MASK_5200|MASK_68060|MASK_68040|MASK_68040_ONLY)}, \ { "68030", (MASK_68020|MASK_BITFIELD)}, \ --- Izumi Tsutsui [email protected]
