Re: Native compilation: the bird-eye view

[Andrea Corallo]

Currently a .el file is compiled as:

/bar/foo.el => /bar/eln-x86_64-pc-linux-gnu-d241bf45dde51f21/foo.eln

where the directory name eln-... disamiguates architecture triplet and
Emacs version/configuration.

One option would be in case to fall back in deposing the eln in something
like:

~/.emacs.d/eln-cache/bar/eln-x86_64-pc-linux-gnu-d241bf45dde51f21/foo.eln

Both the directories would be added into the effective load path during
load if existing.

The logic to fallback from the first option to the second could be as
simple as "if I have no write access on /bar just fallback" to something
more complex.

This way we could distribute binaries but also have deferred compilation
working in all situations.
