Why?

In Subsets.props, <PrimaryRuntimeFlavor Condition="'$(TargetArchitecture)' == 's390x' or '$(TargetArchitecture)' == 'armv6'">Mono</PrimaryRuntimeFlavor> should be setting PrimaryRuntimeFlavor to Mono, then <DefaultCoreClrSubsets Condition="'$(PrimaryRuntimeFlavor)' != 'CoreCLR'">clr.iltools+clr.packages</DefaultCoreClrSubsets> should be setting it so the clr subset only builds the supported CoreCLR components

I may be failing to parse how coreclr/ci.yml works.

According to the message, this should be #0-#6:

runtime/src/coreclr/pal/inc/unixasmmacrosarm.inc

Line 261 in 57bfe47

tst r0, #7

Don't know what would be the implication of changing #7 to #6. cc @janvorli

Alternatively, we can skip armv6 here:

runtime/src/coreclr/pal/inc/unixasmmacrosarm.inc

Line 258 in 57bfe47

#ifdef _DEBUG 

if defined(_DEBUG) && !defined(TARGET_ARMV6)

to get by the error.

Commencing build of " runtime alljits paltests_install nativeaot spmi " target in "CoreCLR component" for Linux.armv6.Checked in /__w/1/s/artifacts/obj/coreclr/Linux.armv6.Checked

@directhex hmm... I think it's this template eng/pipelines/coreclr/templates/build-job.yml invoking src/coreclr/build-runtime.sh directly, not using subsets

runtime/eng/pipelines/coreclr/templates/build-job.yml

It would be invalid change.

We should not be compiling this file for arm v6 at all. These .s files would require substantial changes to work correctly on arm v6.

I think it is done this way to match s390x coverage (which builds il{d}asm tools along with mono). However, s390x required libunwind updates and https://github.com/dotnet/runtime/blob/57bfe474518ab5b7cfe6bf7424a79ce3af9d6657/src/coreclr/pal/inc/unixasmmacross390x.inc to make those scenarios work. We would either need armv6 equivalent or disable clr.iltools+clr.packages subsets from building armv6. @directhex, per @jkotas' suggestion, we should disable those subsets armv6 for now (that will unblock the CI, outerloop legs).

clr.iltools should not need any asm macros or libunwind to work. It is accidental dependency.

This PR made some assembly changes, those should be reverted too? I agree that clr.iltools alone does not require many add_subdirectory() calls src/coreclr/CMakeLists.txt and changes in jit etc. which were made for armv6 and s390x shouldn't be needed.

A whole bunch of the iltools build fails without asm macros and libunwind, largely via coreclr pal/ and util/ dirs.
