Bug 2338605

Looks like the same problem as bug 2336714.

Feels like at least related to https://gcc.gnu.org/PR117886

*** Bug 2339739 has been marked as a duplicate of this bug. ***

I was able to reproduce this on a mock build of emacspeak on aarch64, with a crash in the in-memory compiler:

  libgccjit.so: <built-in>:0:0: error: in jit_langhook_pushdecl, at jit/dummy-frontend.cc:1375

I copied in a build of libgccjit.so.0.0.1 with the fix from upstream commit
https://gcc.gnu.org/git/?p=gcc.git;a=commitdiff;h=27470f9a818538fadb0e458a272358c7141fcd8c

and it gets *much* further: the in-memory "compile" seems to have succeeded, and it's failing running the driver (to turn the .s file into a .so) with:

Error: error ("Eager macro-expansion failure: (native-compiler-error (lambda (arg0 &rest arg1) (let ((f #'funcall-interactively)) (apply f arg0 arg1))) \"Compiling /builddir/.emacs.d/eln-cache/29.4-70b1d7ab/subr--trampoline-66756e63616c6c2d696e7465726163746976656c79_funcall_interactively_0.eln...

presumably due to me using a libgccjit.so with totally wrong configure settings (or maybe I've messed up my chroot).

So this may well be fixed by that upstream commit; i.e. r15-7126-g27470f9a818538.

I'm wondering if there's any info from the emacs side on how to tweak libgccjit's debugging/logging options to better see what's going on internally?  (there are a bunch of such options inside libgccjit, but I'm not sure how they're wired up in emacs, if at all; see https://gcc.gnu.org/onlinedocs/jit/topics/contexts.html#debugging from the libgccjit C API side)

Aha: if I run:

LIBRARY_PATH=/usr/lib/gcc/aarch64-redhat-linux/15/ make emacspeak

with my hacked up libgccjit.so.0.0.1 it seems to be building the .el files successfully:

emacspeak-loaddefs.el
outloud-voices.el
espeak-voices.el
mac-voices.el
voice-setup.el
voice-defs.el
emacspeak-pronounce.el
emacspeak-speak.el
emacspeak-sounds.el
emacspeak.el
emacspeak-setup.el
emacspeak-keymap.el

In end of data:
emacspeak-2048.el:155:7: Warning: the function ‘2048-init-tile’ is not known to be defined.
emacspeak-2048.el:94:8: Warning: the function ‘2048-print-board’ is not known to be defined.
amixer.el
emacspeak-2048.el
emacspeak-abc-mode.el
emacspeak-add-log.el
emacspeak-analog.el
emacspeak-annotate.el

[...etc...; hasn't finished yet]

So it looks like we need a gcc build with upstream commit r15-7126-g27470f9a818538 to fix emacs compilation on non-x86_64 archs.

Though I see that the s390x failure is a different one; taking a closer look...

gcc-15.0.1-0.4.fc42 in rawhide should have the various libgccjit fixes in it (it is r15-7207 based).

Emacs builds successfully on all architectures with the GCC now in rawhide.  Thanks.
