  Hi.
This patch fixes the bug 113842.
I cannot yet add a test with this patch since it requires using
try/catch which is not yet merged in master.
Thanks for the review.

Thanks; patch looks good for trunk, assuming you've tested it on a
target that defines ASM_OUTPUT_EXTERNAL.

It's OK to merge even though it touches files outside of the jit
directory and we're in stage 4?
Or do we need some kind of approval?

I think this patch is sufficiently low-risk that you can go ahead and
merge it.

Subject: [PATCH] libgccjit: Clear pending_assemble_externals_processed

Without this patch, code using exception handling will fail the
following assert in the function assemble_external_libcall in varasm.cc:

    gcc_assert (!pending_assemble_externals_processed)

gcc/ChangeLog:
	PR jit/113842
	* toplev.cc (toplev::finalize): Call varasm_cc_finalize.
	* varasm.cc (varasm_cc_finalize): New function to clear
	pending_assemble_externals_processed.
	* varasm.h (varasm_cc_finalize): New function.
