Comment:
All patches, up to and including #23, are sufficient to both compile, and link,
the libgccjit shared library. However:
• The build fails immediately thereafter, due to an improperly specified
dependency, in the GCC Makefile; this is corrected by the trivial
24-libgccjit-full-driver-name.patch.
• Although the generated libgccjit shared library is, in fact, a Windows DLL,
it is named according to ELF convention, with a .so extension, and multiple
symbolic links to variously version-annotated alternatives; furthermore, no
accompanying libgccjit.dll.a, (as we would normally expect for a Windows
build), is created.
The latter failing is corrected by the attached
25-libgccjit-mingw-link-options.patch; this modifies the link command, for the
Windows build-case, to name the generated shared library as libgccjit-0.dll,
while also creating the libgccjit.dll.a import library, as a linker side
effect. Additionally, it modifies the installation commands, to install both
the DLL, and its import library, into appropriate locations.

Ticket details:
Please add libgccjit to the binaries included in the MinGW GCC distributions.
This is required to be able to build projects that use libgccjit for JIT
compilation of code. One example of this is "gccemacs", a branch of GNU Emacs
development (soon to land on the master branch of Emacs) that compiles Emacs
Lisp programs into native x86 code for faster runtime performance.
Thank you.

Although this is still WIP, AFAIU, I would like to thank you for your efforts

Comment:
Since all Windows code is position independent anyway, and the reason that JIT
requires configuration with --enable-host-shared appears to be to ensure
position independence of generated code, it seems likely that the
--enable-host-shared option is not actually required for a MinGW build of
libgccjit-0.dll; however, the current behaviour of GCC's configure script
enforces the requirement that it be specified. The attached
26-libgccjit-mingw-host-shared.patch overrides such enforcement, in the
specific case of building for a MinGW target, allowing the whole caboodle to be
built in a single operation, without requiring specification of
--enable-host-shared.

Comment:
Having successfully cross-built a MinGW-GCC, inclusive of libgccjit-0.dll, but
uncertain how to effectively test it, I followed Eli's suggestion from this
mailing-list posting:
Is the produced libgccjit functional?
I don't know. I suspect that the testsuite will be inadequate, when
cross compiling, and I don't know how to test it, otherwise.
This tutorial has a simple text program, it seems:
https://gcc.gnu.org/onlinedocs/jit/
and copied the sample program from part 1 of the libgccjit tutorial, for use as
a rudimentary test program ... alas, it fails spectacularly, with a
segmentation fault which will require further investigation.
