Remember, this check is happening once per insn, not once per tb. r~

Remember, this > check is happening once per insn, not once per tb. Maybe I should hoist the check up to the start of a block? This would mean we would dump all instructions in a block even if they went past the end-point but the reverse case is probably just confusing. We'll still not dump anything that starts outside the range. > > > r~

Why hoist when the loglevel_mask check is so quick? Processing of these debug opcodes is equally quick. It's really only the dumping of the opcodes elsewhere that needs to check the addr_range. r~

Each individual architecture needs to use the qemu_log_in_addr_range() feature for enabling in_asm and marking blocks for op/opt_op output.
