Bug 1159775

@fcrozat, can you take care of this?

The build definition seems to come from the Firefox package. Firefox uses certain features only available on i686. I'm not totally sure about the JS engine though. It might be also the case so when certain functions are used from the JS lib we may still run into a runtime issue but at least the lib consumers still can and link against the lib.

Not sure what the longer term solution might be though.
glibc also is i686 so I guess i586 binaries should still be able to use i686 libs? Not sure what is required to make this work.
Also question is if a component like mozjs (being used by Gnome AFAIK) can be i686 w/o starting to require i686 hardware as a baseline for the whole distribution?

Sorry about that.

I switched mozjs60 to i686 because it was the only way to get it to pass properly all its testsuite succesfully on 32bit intel (and this is what Fedora is also doing).

I'll revert this change and will have to disable some tests on i586 :(

Sorry, I didn't notice the change was already done in devel project. It would have been better to not change the past history in the package changelog but add another changelog entry (those changes were already in SLE 15 SP2 / Leap 15.2).

Closing as fixed

reopened, dropping i686 without fixing testsuite is not the best idea..

Sorry, this is what I noticed and where I didn't yet proceed.
Feel free to fix the test suite. But as said in the earlier comment building for i586 will mean the possibility for runtime errors due to missing SSE stuff and at the same time I would hope/expect that we could handle mozjs similar to glibc. I have no clue what can or would need to be done though.

In progress.

Well, the failure are in floating point handling and so far, nobody has complained (since tests were not enabled, nobody noticed until I made sure they were enabled on all possible platforms). For now, I'll keep the previous state by disabling the tests on i586.

fixed now with sr#760063

please accept it.
