3484Enabling language "jit" requires --enable-host-shared.
3485
3486--enable-host-shared typically slows the rest of the compiler down by
3487a few %, so you must explicitly enable it.
3488
3489If you want to build both the jit and the regular compiler, it is often
3490best to do this via two separate configure/builds, in separate
3491directories, to avoid imposing the performance cost of
3492--enable-host-shared on the regular compiler.])
