GetRuntimeUnwindPlan() [2/2]

UnwindPlanSP LanguageRuntime::GetRuntimeUnwindPlan ( lldb_private::Thread &  thread, lldb_private::RegisterContext *  regctx, bool &  behaves_like_zeroth_frame  )

static

A language runtime may be able to provide a special UnwindPlan for the frame represented by the register contents regctx when that frame is not following the normal ABI conventions.

Instead of using the normal UnwindPlan for the function, we will use this special UnwindPlan for this one backtrace. One example of this would be a language that has asynchronous functions, functions that may not be currently-executing, while waiting on other asynchronous calls they made, but are part of a logical backtrace that we want to show the developer because that's how they think of the program flow.

Parameters

[in]	thread	The thread that the unwind is happening on.
[in]	regctx	The RegisterContext for the frame we need to create an UnwindPlan. We don't yet have a StackFrame when we're selecting the UnwindPlan.
[out]	behaves_like_zeroth_frame	With normal ABI calls, all stack frames except the zeroth frame need to have the return-pc value backed up by 1 for symbolication purposes. For these LanguageRuntime unwind plans, they may not follow normal ABI calling conventions and the return pc may need to be symbolicated as-is.

Returns

Returns an UnwindPlan to find the caller frame if it should be used, instead of the UnwindPlan that would normally be used for this function.
