[Lldb-commits] [PATCH] D112069: [lldb][AArch64] Add UnwindPlan for Linux sigreturn

[David Spickett via Phabricator via lldb-commits]

DavidSpickett added inline comments.


================
Comment at: lldb/source/Plugins/Platform/Linux/PlatformLinux.cpp:258
+  UnwindPlanSP unwind_plan_sp;
+  if (name != "__kernel_rt_sigreturn")
+    return unwind_plan_sp;
----------------
PlatformLinux lists 3 handlers:
* _sigtramp
* __kernel_rt_sigreturn
* __restore_rt

I think the first 2 are the same for AArch64 due to this line in the kernel:
VDSO_sigtramp                = __kernel_rt_sigreturn;

The third is for real time signals which I'm only just learning about. So I'll see what that's about but probably not relevant for this change.
