Added the dwarf maintainers hoping to get an answer. From an RTEMS perspective,
the lm32 is not usable. Both 4.9 and the head are broken. Hoping you two have
an idea. Happy to help since this is a cross target.

(In reply to Uroš Bizjak from comment #4)
> is not the correct way to set /f flags to all insn of the generated sequence.
Please see how mips/mips.c annotates expanded sequences using
mips_set_frame_expr, especially stack pointer adjustment description in mips.c,
around line 11620.

I am not an expert on the machine descriptions or the lm32. If someone wants to
propose a patch, I am happy to test it.

--- Comment #7 from Joel Sherrill <joel at gcc dot gnu.org> ---
I added Jon Beniston who did the initial port and Sebastien Bourdeauducq who is
listed as the lm32 maintainer but hasn't committed since 2011. I hope one of
them can help out here.
