Build regressions/improvements in v5.6

Build regressions/improvements in v5.6

[Geert Uytterhoeven]

Below is the list of build error/warning regressions/improvements in
v5.6[1] compared to v5.5[2].

Summarized:
  - build errors: +5/-0
  - build warnings: +148/-180

JFYI, when comparing v5.6[1] to v5.6-rc7[3], the summaries are:
  - build errors: +0/-0
  - build warnings: +1/-0

Note that there may be false regressions, as some logs are incomplete.
Still, they're build errors/warnings.

Happy fixing! ;-)

Thanks to the linux-next team for providing the build service.

arcv2/axs103_smp_defconfig

It's probably due to a broken configuration for the arc toolchain.

I think I do have some but first I'd like to get it reproduced myself.
I just built v5.6 with help of both GCC 8.3.1- & 9.3.1-based toolchains
and didn't see a single warning. So I guess I was doing something wrong.

FWIW

1. My GCC 8.3.1 toolchain was exactly this:
https://github.com/foss-for-synopsys-dwc-arc-processors/toolchain/releases/download/arc-2019.09-release/arc_gnu_2019.09_prebuilt_uclibc_le_archs_linux_install.tar.gz

2. Linux kernel is vanilla v5.6.0

3. Configured and built as simple as:
   make axs103_smp_defconfig && make

It seems the build service is using a arc toolchain built in 2016 :-)

# < /opt/cross/kisskb/br-arcle-hs38-full-2016.08-613-ge98b4dd/bin/arc-linux-gcc

Call it Murphy's law, same year a little later I'd fixed the same issue in gcc [1]

[1] http://lists.infradead.org/pipermail/linux-snps-arc/2016-October/001661.html

@Guenter could you please consider updating the ARC tools. FWIW you can build
stuff off upstream gcc/binutils using build system of your choice.

Thx,

I am currently using vanilla gcc 9.2.0 to build arc and arcv2 images. Are you saying
that I need to update to gcc 9.3.0 ? gcc 9.3.0 was released only a couple of weeks
ago. I don't usually jump onto new compiler releases that quickly because each
release tends to have regressions.

No you are good. The issue was Micheal's toolchain from 2016 sources.
