Hi,
Since PR71151 we have jump-tables in .text so that branches
crossing the tables have longer offsets that needed.
This moves jump-tables out of test again, but not into
.progmem.gcc_sw_tables like before PR71151, but into
the currently unused but existing .jumptables.
Since PR63223 there is no restriction on the location
of jump-tables, they can even reside above 128KiB without
problems.
Also adds -mlog=insn_addresses to dump insn addresses
as asm comments before respective instruction.
The patch implements ASM_OUTPUT_ADDR_VEC so that avr.c
gains full control over the table generation.
Tested on ATmega2560.
Ok to apply?
Johann
