Depends on optimization and the type of instruction. Are you
refererring to one-byte, two-byte, three-byte or four-byte
instructions. Are we taking in consideration compound instructions?
What platform? (ARM, MIPS, Intel, PPC?)
So... No . there isn't a rule of thumb, and you can't just count
instructions. Isn't there a mixed display? (C-code mixed with the
assembly in alternated lines?)
Probably gdb + ddd can be of help here?
