--- Comment #2 from Vincent Riviere <vincent.riviere at freesbee dot fr> --- Cause is in gcc/config/m68k/linux.h, macro ASM_RETURN_CASE_JUMP: https://gcc.gnu.org/git/?p=gcc.git;a=blob;f=gcc/config/m68k/linux.h;h=2e1cb5498b86f053d1e9b7c530648dfa186ca4c4;hb=HEAD#l96 jmp %%pc@(2,%0:w) Offset 2 is hardcoded in the macro. Ideally, it should be replaced with the label of the first jump table entry. But I guess it isn't possible inside that macro. A solution is to force ADDR_VEC_ALIGN to 0, in order to completely disable the jump table alignment. That's consistent with ASM_RETURN_CASE_JUMP expectations. #define ADDR_VEC_ALIGN(ADDR_VEC) 0 This should be done for all m68k targets.
