Try for yourself. '-m32 -O2 -march=i386' is your friend.
Ciao,
Michael.
Spoiler: it's generating:

libgcc2 is written in C; so if it fails to compile you need to fix up
your backend. There might need some middle-end fixes too with this
small n

your backend. There might need some middle-end fixes too with this
small number of registers used. You mig

One of the four Registers is defined as Basepointer and another as
