Mark Wielaard <mwielaard@redhat.com> writes: On some systems executable stacks are denied. Since libunwind and the tests don't actually need executable stacks this patch marks all assembly files as not needing it. The original patch comes from frysk: 2007-04-05 Jan Kratochvil <jan.kratochvil@redhat.com> * src/hppa/getcontext.S, src/hppa/setcontext.S, src/hppa/siglongjmp.S, src/ia64/Ginstall_cursor.S, src/ia64/Linstall_cursor.S, src/ia64/dyn_info_list.S, src/ia64/getcontext.S, src/ia64/longjmp.S, src/ia64/setjmp.S, src/ia64/siglongjmp.S, src/ia64/sigsetjmp.S, src/ppc64/longjmp.S, src/ppc64/siglongjmp.S, src/x86/longjmp.S, src/x86/siglongjmp.S, src/x86_64/longjmp.S, src/x86_64/setcontext.S, src/x86_64/siglongjmp.S: Stack should be non-executable, for SELinux. I added a couple more markers for new files in current libunwind. Before this patch you would get the following on selinux enabled systems without allow_exec_stack: error while loading shared libraries: libunwind.so.7: cannot enable executable stack as shared object requires: Permission denied After the patch that error disappears and all test results are similar to the results on systems without executable stack protection.

(rbs_spill_NN): If r8 is non-negative on return from subroutine-call, increment it by one. Take care of restoring the dirty partition before switching back to original backing store. (LD_LOC): Load only 4 bytes, not 8 bytes. (CK_LOC): New macro. (loadup): ar.pfs is saved in r36, not r34. After returning from subroutine call, check local variables to make sure they still contain the correct values. (resumption_point): New function. (Logical change 1.49)
