PATCH 1/2 Makefile: support defconfigs in subdirectories

The pattern rule %_defconfig doesn't support a pattern that includes a / because of the following weird make behavior. From the GNU make info page:

When the target pattern does not contain a slash (and it usually does not), directory names in the file names are removed from the file name before it is compared with the target prefix and suffix. After the comparison of the file name to the target pattern, the directory names, along with the slash that ends them, are added on to the prerequisite file names generated from the pattern rule's prerequisite patterns and the file name.

In other words, foo/bar_defconfig would depend on foo/configs/bar_defconfig instead of configs/foo/bar_defconfig.

As a workaround, introduce an intermediate target that does contain a / and where the pattern is at the beginning: %/.../defconfig. Since this target does contain a /, the weird splitting of the pattern doesn't occur and we can make that target depend on .../configs/%_defconfig.

It gets slightly more complicated still because chains of pattern rules only work if they all have commands. So we need to add a dummy command for the %_defconfig rule.

PATCH 2/2 configs: add autobuild configs

We currently have a list of toolchain configurations that are used by the autobuilders at [1]. However, this makes it a little more difficult for people to use these configurations, and also to have a different list of configurations for different branches. For example if a new architecture is introduced, the 2017.02.x branch doesn't have support for this architecture yet so it shouldn't try to run those configs.

Therefore, include the autobuild defconfigs directly in Buildroot, so they can be branched together with the rest. To avoid polluting the configs/ directory too much, the autobuild defconfigs are kept in an "autobuild" subdirectory.

The toolchain-configs.csv file also contained additional information:
the hostarch required by the toolchain binary, and the libc used. The latter can be found in the defconfig itself, but the hostarch isn't in there. To avoid still having to maintain a separate file, we just add a BR2_HOSTARCH string to the defconfig file. When the defconfig is used this string is completely ignored, but it can be used by the autobuild-run script.

The changes to the autobuild-run script still have to be done. It's not entirely trivial :-) so I didn't feel up to it.

Instead of this approach, I also considered adding the buildroot-generated toolchains as external toolchains to the menus. However, then there would still be a need for config files that specify the subarch used, as well as e.g. STATIC. While with this approach the entire toolchains/configs directory can be removed from autobuild.buildroot.net.

PATCH 2/2 configs: add autobuild configs

Hello,

Quoted 7 lines · Arnout Vandecappelle (Essensium/Mind)

We currently have a list of toolchain configurations that are used by the autobuilders at [1]. However, this makes it a little more difficult for people to use these configurations, and also to have a different list of configurations for different branches. For example if a new architecture is introduced, the 2017.02.x branch doesn't have support for this architecture yet so it shouldn't try to run those configs.

Quoted 8 lines

Therefore, include the autobuild defconfigs directly in Buildroot, so they can be branched together with the rest. To avoid polluting the configs/ directory too much, the autobuild defconfigs are kept in an "autobuild" subdirectory.

The toolchain-configs.csv file also contained additional information:
the hostarch required by the toolchain binary, and the libc used. The latter can be found in the defconfig itself,

How is the latter found in the defconfig? For example, with:

+BR2_HOSTARCH="x86"
+BR2_x86_pentium4=y
+BR2_TOOLCHAIN_EXTERNAL=y
+BR2_TOOLCHAIN_EXTERNAL_CODESOURCERY_X86=y

How will the autobuilder script know that it is a glibc toolchain?

Quoted 5 lines

but the hostarch isn't in
there. To avoid still having to maintain a separate file, we just add a BR2_HOSTARCH string to the defconfig file. When the defconfig is used this string is completely ignored, but it can be used by the autobuild-run script.

So this BR2_HOSTARCH option needs to be added manually to the
defconfig: the defconfig are not directly the result of "make savedefconfig", correct?

Quoted 6 lines

Instead of this approach, I also considered adding the buildroot-generated toolchains as external toolchains to the menus. However, then there would still be a need for config files that specify the subarch used, as well as e.g. STATIC. While with this approach the entire toolchains/configs directory can be removed from autobuild.buildroot.net.

I also think this approach doesn't make much sense, because several of the autobuild toolchains really don't make sense to have exposed in Buildroot external toolchain menu. Some toolchain configurations only exist just for the sake of testing interesting combinations.

Examples: the ARM no-thread toolchain, the basic PowerPC toolchain with just C++ support, the ARM/glibc toolchain that intentionally always uses the latest available version of gcc/binutils/glibc, etc.

Other than the issues raised above, I'm generally fine with the idea, I think it makes sense. If we are going to change the architecture of the autobuild-run there are lots of different things that could be done:

- Testing different branches, like you are suggesting.

- Change how "exceptions" are handled. Currently, people have to update their autobuild-run script to have the updated list of exceptions. It would be nice if this was not necessary, either by having the configuration generated by the autobuild server, or by having this list of exceptions in Buildroot itself so that it gets naturally updated when pulling the latest version of the source code.

Best regards,

Thomas

I didn't think of that :-)

But actually, as far as I can see, the only thing this is used for in the
autobuild-run script is to decide whether or not to add BR2_STATIC_LIBS=y. But we can do that unconditionally - it will get removed by 'make oldconfig'.

Indeed.

I'm open to suggestions of a different approach, of course :-)

One option would be to add further subdirectories for x86 and x86_64, but I
don't really like that.

"issues" -> do you mean just the libc issue, or do you consider the
savedefconfig issue sufficiently severe that it needs a solution before committing?
