As some may have seen I posted a patch to gcc-patches that adds a way to
embed GCC as a shared library, for Just-In-Time compilation, for use
e.g. by bytecode interpreters:
I've gone ahead and created a git-only on the mirror as branch
and I've been committing patches there.
I plan to post some of the patches for review against trunk (am
bootstrapping/regtesting them as I write).
An example of using it can be seen at:
Some questions for the GCC steering committee:
* is this JIT work a good thing? (I think so, obviously, but can I go
ahead and e.g. add it to the wiki under "Current Projects"?)
* do you like the general approach? I'm choosing to deliberately hide
as much as possible of GCC's insides, trying to hit the use-case
of being able to add a JIT to an existing interpreted language whilst
* it seems worthwhile to have a place to discuss the JIT work: both in
terms of development *of* the branch, and for developers wishing to
*use* the library in their own projects. I strongly feel that the
only good APIs are those that are developed alongside *users* of
those APIs (this forces one to smooth off the rough edges from the
Hence is it reasonable to have a "email@example.com" mailing list for
* what would need to happen to get this into 4.9? or is this an

mailing list as I commit them? Also, should this be just a "jit"
branch? (i.e. not under "dmalcolm/")
