--- Comment #3 from Senthil Kumar Selvaraj <senthil.thecoder at gmail dot com> --- Yeah, it's a 6.x thing. There's a commit that changes varasm.c from using targetm.asm_out.mergeable_rodata_prefix to a function call to targetm.asm_out.function_rodata_section hook if the section category is SECCAT_RODATA_MERGE_STR. So avr_asm_function_rodata_section now gets called for string literals inside functions, not just jumptables. I'm trying out a fix that propagates the section category down to the target hook and have the avr backend use it to distinguish between jumptables and other data.
