This feature is also arch and toolchain specific.
Current glibc on alpha, powerpc, sparc, ia64, s390, amd64
should work just now, someone (DD, of course) can verify it
using test case from #226716 against sarge supported kernels.
Unofficial architectures kfreebsd-i386, kfreebsd-amd64, ppc64
already support it.
i386 can be easily fixed when
- support for real i386 hardware is dropped (already done)
- support for pre-2.4 kernels is dropped (seems planned, see #339827)
glibc fix contains two steps:
- add "libc_MIN_KERNEL_SUPPORTED=2.4.1" into debian/sysdeps/i386.mk
- copy linuxthreads/sysdeps/i386/i686/pt-machine.h into linuxthreads/sysdeps/i386/i486/pt-machine.h
Other architectures probably does not yet support __thread at all.
