Disable JIT:
make -f Makefile.ref NANOJIT_ARCH=i386 DISABLE_JIT=1
Enable JIT:
make -f Makefile.ref NANOJIT_ARCH=i386 ENABLE_JIT=1
(it’s ENABLE_JIT not DISABLE_JIT in this case, sorry for the mistake before)
I used V8 and SunSpider benchmarks for tests. But it seemed that there was no difference between JIT ‘on’ and ‘off’ from the results. I guess maybe JIT could not be turned on in the above way. Do you know how to enable it?
Thank you very much.

Recently, I tried to build the tracemonkey JavaScript engine in Firefox instead of the whole browser. I compiled tracemonkey-debe29698839\js\src like this:

Disable JIT:
make -f Makefile.ref NANOJIT_ARCH=i386 DISABLE_JIT=1
