Where is "libgccjit"?

Where is "libgccjit"?

[take]

To all participants in jit@gnu ml.

My name is Takeo Watanabe and I am sending you a mail from Japan.

I am trying to build native compiled Emacs on macOS.
I also want to build from source as much as possible, do not use
Homebrew.

So far, I have completed building libxml2 and gcc12.1.
I have not been able to find libgccjit either in the archive or in git,
and I have not been able to find it in the git file.
I have not been able to find it in archive or git yet.

If anyone knows where I can find it, please let me know.
Please let me know. Thank you in advance.

best regards.

libgccjit is part of gcc; it looks like a frontend to the rest of gcc,
named "jit".  The code is in the gcc/jit subdirectory of the gcc source
tree.

So you need to configure the build of gcc with:
   --enable-languages=jit --enable-host-shared

There are some more notes on building libgccjit here:

Hope this is helpful; good luck
