Conversion from tree to RTL is in cfgexpand.c, stmt.c and expr.c. Have you ever tried using grep to find this kind of information, or do you simply find it easier to ask on gcc-help? You might also try IRC as mentioned on gcc.gnu.org/wiki; you will get faster turnaround if you stay on-topic. > Can anyone know at which file(function), vector code > in GIMPLE is transformed to RTL vector code???? Same answer, though some of the details are in optabs.c. Ian
