Issue 12092 – Wrong TLS access in PIC code (X86_32)

Seems reasonable.
@MartinNowak - I know this is offtopic a little, but should we have a talk about setting goals for representing D types/modules/etc. in debug sometime soon?

If we can have all compilers at parity with anything that requires specific knowledge of how D works, then any improvements I make on the gdb side will help everyone.

Sure, how about here https://issues.dlang.org/show_bug.cgi?id=11660.

Maybe this PR introduces the Linux 32bit link failure in test/runnable/s2ir.d.
https://auto-tester.puremagic.com/?projectid=1

(Strangely, the failure does not appear in pull request testers)

That could be because the pull testers don't run the full set of compiler switch permutations. I think this would be the first time running the full permutations actually caught a bug that the fast mode missed.

Yeah, will look at it.

Yeah, will look at it.

Thank you.
