32-bit linux specs are broken (#11073) and it appears hard to even diagnose the error or even fix it (#11077). Considering the limited relevance of 32-bit linux platforms, there's not a lot of force behind this.
Having a test that constantly fails doesn't help anything.
The core team decided to move platform support for
i386-linux-gnu
to tier 2. The platform is still supported and it's still expected to build (the errors seem to be very specific to the test environment). But we won't run automated tests anymore (at least for the time being). The tests were already incomplete, running onlystd_spec
on the latest release compiler. But no compiler build orcompiler_spec
. So this step is really not a huge change.Closes #11077.
