Subject: [PATCH] PR target/13292 * config/m68k/m68k.h
(TARGET_SWITCHES): Don't remove MASK_68040_ONLY on -msoft-float.
(TARGET_FLT_EVAL_METHOD): Don't advertise extended precision for 68040
and soft-float. * config/m68k/m68k.md (truncdfsf2): Explicitly require
TARGET_68881 in the TARGET_68040_ONLY case.
