I am modifying some gcc source files ...
Can anybody tell me how to "quick rebuild" gcc (i.e. rebuild only modified
source files) instead of starting from "make bootstrap" everytime ?
thanks,

'make quickstrap" usually will usually accomplish what you're requesting.

cd build-tree/gcc
make -j2 cc1plus
or
make -j2 cc1
is not an uncommon way to do this. Takes 15 seconds on my machine.

Except it won't do what you expect, because it won't use the stageN
compiler to build stage N+1. That's what quickstrap and bubblestrap
are for - they know what the bootstrap state is, and use the right
compiler to recompile.
