AlwaysRelyOnEHUnwindInfo()

bool DynamicLoaderDarwin::AlwaysRelyOnEHUnwindInfo ( lldb_private::SymbolContext & sym_ctx )

overridevirtual

Ask if the eh_frame information for the given SymbolContext should be relied on even when it's the first frame in a stack unwind.

The CFI instructions from the eh_frame section are normally only valid at call sites – places where a program could throw an exception and need to unwind out. But some Modules may be known to the system as having reliable eh_frame information at all call sites. This would be the case if the Module's contents are largely hand-written assembly with hand-written eh_frame information. Normally when unwinding from a function at the beginning of a stack unwind lldb will examine the assembly instructions to understand how the stack frame is set up and where saved registers are stored. But with hand-written assembly this is not reliable enough – we need to consult those function's hand-written eh_frame information.

Returns

True if the symbol context should use eh_frame instructions unconditionally when unwinding from this frame. Else false, the normal lldb unwind behavior of only using eh_frame when the function appears in the middle of the stack.

FindEquivalentSymbols()

void DynamicLoaderDarwin::FindEquivalentSymbols ( lldb_private::Symbol * original_symbol, lldb_private::ModuleList & module_list, lldb_private::SymbolContextList & equivalent_symbols )

overridevirtual

Some dynamic loaders provide features where there are a group of symbols "equivalent to" a given symbol one of which will be chosen when the symbol is bound.

If you want to set a breakpoint on one of these symbols, you really need to set it on all the equivalent symbols.

Parameters

[in]	original_symbol	The symbol for which we are finding equivalences.
[in]	module_list	The set of modules in which to search.
[out]	equivalent_symbols	The equivalent symbol list - any equivalent symbols found are appended to this list.
