I don't have details of exactly what uses of flexible array members they
were making beyond those permitted by ISO C.  I guess the general point is
to be careful about disallowing such uses because it might break existing
code (so allowing plenty of time before a release for distribution
rebuilds to catch any problems with such a change, for example).

Yes, I'd rather see this change with relevant part of Comment #4 together.

The combined patch is pre-approved, after it is tested correctly.

arm-linux-gnueabi-gcc neon.c -Os -fno-omit-frame-pointer -mapcs
-mabi=aapcs-linux -mfloat-abi=softfp -mfpu=neon -g -S -marm

neon.c: In function ‘raid6_neon4_gen_syndrome_real’:
neon.c:79:1: internal compiler error: in dwarf2out_frame_debug_adjust_cfa, at
dwarf2cfi.c:1090

Root cause:
When expanding epilogue, REG_CFA_ADJUST_CFA NOTE is added to handle dwarf info
issue for shrink-wrap. But for TARGET_APCS_FRAME, shrink-wrap is disabled. And
not all dwarf info in arm_expand_epilogue_apcs_frame are correctly updated.
arm_emit_vfp_multi_reg_pop is called by both arm_expand_epilogue_apcs_frame and
arm_expand_epilogue. So we should not add the NOTE in
arm_emit_vfp_multi_reg_pop if shrink-wrap is not enabled.

--- Comment #11 from Jeffrey A. Law <law at redhat dot com> ---
I hacked up a RHL 8 system far enough to try and build os-unix.c.  I can
confirm that I got the error in this bug report and that it compiled
successfully after your patch Balaji.

Other issues get in the way of doing a full build/test, but RHL8 is so old that
