On my m68k-atari-mint port, the code generated by GCC is a bit different.
Especially, I don't have those lines:
.const
.align 1
...
.text
That's quite surprising because I can't find that ".const" directive in the
gas manual. I don't know what it does. But if the goal of that directive
would be to change the output section, the generated code may be wrong, due
to PC-relative addressing.
I suspect you have that ".const" somewhere in your configuration file, maybe
in the ASM_OUTPUT_CASE_END macro. If this is the case, try to remove that.
See the documentation there:
http://gcc.gnu.org/onlinedocs/gccint/Dispatch-Tables.html
Also, the following define is probably mandatory if your target allows a
separate read-only data section :
#define JUMP_TABLES_IN_TEXT_SECTION 1
See there:
http://gcc.gnu.org/onlinedocs/gccint/Sections.html#index-JUMP_005fTABLES_005fIN_005fTEXT_005fSECTION-4432
Good luck.
NB: From the two macros above, JUMP_TABLES_IN_TEXT_SECTION is probably the
closest to your solution.
