LWTools: lwasm/insn_indexed.c annotate

annotate lwasm/insn_indexed.c @ 283:210d261a614d

Make byte overflow detection for indexing work better There are *two* places where indexed addressing is calculated - lea style instructions and general addressing instructions. Actually check for byte overflows in both places. Also, extend byte overflow checking to all 8 bit offsets from index registers, not just PCR.
