File tls-no-direct.diff of Package cross-hppa-gcc11.24034
For i?86 negative offsets to %fs segment accesses cause a hypervisor trap for Xen. Avoid this by making accesses indirect. ??? Note that similar to the behavior on SLE11 this only affects the compiler built on %ix86, not that on x86_64, even with -m32.
