I don't know what you mean by "mach pass".
I'd hazard a guess Abdul is referring to the machine dependent reorg
pass, which has the .mach debugging dump file.
The machine dependent reorg pass is a late optimization pass (runs just
prior to delay slot filling) that is entirely machine dependent. It is
generally frowned upon to implement optimizations in the machine
dependent reorganization pass, though several ports now implement such
optimizations, including:
alpha, arm, avr, bfin, frv, h8300, x86, ia64, m68hc11, mcore, mep, mips,
mmix, pa, pico, s390, sh, spu, xstormy16, v850.
