Hi Michael, > The H8300 linker currently only relaxes MOV instructions with addressing > modes "absolute address". > MOV instructions with addressing mode "register indirect with > displacement" can also be relaxed from 24/32bit displacement to 16 bit > displacement. > GCC often emits these instructions for switch encoding, table, array or > struct accesses etc. > I would like to add support for these and some testcases too. Is this OK ? Certainly. Please post any patches you create to the binutils mailing list for review. Cheers Nick
