* libguile/lightning/lib/lightning.c (_jit_emit): The default code
allocator will simply mmap a code buffer, try to emit into that
buffer, and if it fails, try again with a larger buffer. However the
buffer size starts at 0, for some reason. Why? I can't see the
reason. Change the default to 4096. In the future we will need to
implement our own allocator anyway so that we can pack multiple JIT
runs in one page.
* libguile/lightning/: New directory, made by the following commands:
git remote add lightning https://git.savannah.gnu.org/git/lightning.git
git merge -s ours --no-commit --allow-unrelated-histories lightning/master
git read-tree --prefix=libguile/lightning/ -u lightning/master
In theory we will be able to update via:
git merge -s subtree lightning/master
