-Subject: [PATCH] ARC: unwind: ensure that .debug_frame is generated (vs.
- .eh_frame)
-
-With recent binutils update to support dwarf CFI pseudo-ops in gas, we
-now get .eh_frame vs. .debug_frame. Although the call frame info is
-exactly the same in both, the CIE differs, which the current kernel
-unwinder can't cope with.
-
-This broke both the kernel unwinder as well as loadable modules (latter
-because of a new unhandled relo R_ARC_32_PCREL from .rela.eh_frame in
-the module loader)
-
-The ideal solution would be to switch unwinder to .eh_frame.
-For now however we can make do by just ensureing .debug_frame is
-generated by removing -fasynchronous-unwind-tables
-
- .eh_frame generated with -gdwarf-2 -fasynchronous-unwind-tables
- .debug_frame generated with -gdwarf-2
-
-Fixes STAR 9001058196
