Cover letter [U-Boot] [PATCH v2 0/3] Add some missing buildman features and deprecate MAKEALL

Buildman has been around for a little over a year and is used by a fair number of U-Boot developers. However quite a few people still use MAKEALL.
Buildman was intended to replace MAKEALL, so perhaps now is a good time to start that process.
OK, lets start. First, I had to make up a special directory with symlinks to the various toolchains, in order to get them to work with buildman, due to the various layouts:
$ ls -l ~/work/u-boot/toolchain-links/ total 4 lrwxrwxrwx 1 trini trini 38 Aug 1 17:09 arc_gnu_4.8-R2_prebuilt_uclibc_be -> /opt/arc_gnu_4.8-R2_prebuilt_uclibc_be lrwxrwxrwx 1 trini trini 38 Aug 1 17:09 arc_gnu_4.8-R2_prebuilt_uclibc_le -> /opt/arc_gnu_4.8-R2_prebuilt_uclibc_le lrwxrwxrwx 1 trini trini 24 Aug 1 17:10 bfin-elf -> /opt/uClinux-45/bfin-elf lrwxrwxrwx 1 trini trini 32 Aug 1 17:09 m68k-linux -> /opt/gcc-4.9.0-nolibc/m68k-linux lrwxrwxrwx 1 trini trini 34 Aug 1 17:09 microblazeel-xilinx-linux-gnu -> /opt/microblazeel-xilinx-linux-gnu lrwxrwxrwx 1 trini trini 32 Aug 1 17:09 microblaze-xilinx-linux-gnu -> /opt/microblaze-xilinx-linux-gnu lrwxrwxrwx 1 trini trini 66 Aug 1 17:15 mips32-linux -> /opt/eldk-5.2.1/mips/sysroots/i686-eldk-linux/usr/bin/mips32-linux lrwxrwxrwx 1 trini trini 36 Aug 1 17:09 nds32le-linux-glibc-v1f -> /opt/nds32le/nds32le-linux-glibc-v1f lrwxrwxrwx 1 trini trini 20 Aug 1 17:09 sparc-elf-3.4.4 -> /opt/sparc-elf-3.4.4

I tried a few things but I couldn't get a toolchain section setup that found all of those. Second:
OK, can you give me a trace of the output of 'buildman --list-tool-chains' - I should be able to figure out what is wrong.
Like Tom, I tried this a bit. (and ended up faking clang is gcc). There are at least some assumptions cc = gcc and strlen(cc) == 3.

So it's nice that it spit out a thread per commit, but I really only care right now if master builds right. And I've gone blind and can't find the end result logs of what failed to build (88 failures doesn't quite match the warning/errors I get for my wrapper around toolchains+MAKEALL).

You can use the -s flag to see the broken builds, and -se to see errors also. Is that what you mean?
The output is in ../<branch>/<commit>/<board> but if you want to keep the binaries, you need -k also.
Like Tom, I saw fancy output, like merged not being a property or something. I like to see the warnings and errors directly, but -e? failed to do so. (or at least I didn't spend enough time to get it to work)

I also didn't quite see how to plugin an arm64 toolchain.
I haven't tried - can you please point me to one and I'll give it a go.

Next up, is there some way to have multiple toolchains for an arch available? On some compute resources I have at work I throw arm/eldk4.2, arm/eldk5.2, arm/linaro-2013.03 (since we've pinned to that for some projects) and some various combos for powerpc as well. I didn't see how to do that with buildman aside from different ~/.buildman files per invocation.

Yes I remember you talking about this before. One option would be to add toolchain as a new dimension in the matrix. It might be painful though. So to be clear, you want to define multiple toolchains for an arch, and have buildman always build with all of them?
I would like this as well. For serious changing I typically build with MAKEALL with clang and gcc (for ARM) + gcc for powerpc if it is a overall change.
But since clang always warns it is actually not a viable target for buildman at all.

Jeroen
