class CallSiteSymbolDataProvider
Defined at line 30 of file ../../src/developer/debug/zxdb/client/call_site_symbol_data_provider.h
Implementation of SymbolDataProvider that links to a function call site within a given frame.
This is ued by a deeper frame to evaluate the registers at the call site for the purposes of
DWARF expressions containing DW_OP_entry_value.
This uses the saved registers for the previous frame (which should be valid at the nested frame's
call site), as well as any DW_TAG_call_site / DW_TAG_call_site_parameter entries corresponding
to the call (see CallSite objects exposed by CodeBlock).
It allows access to memory. Theoretically, any memory could have changed from the time of the
call, but we expect any references from with an "entry value" DWARF expression to make sense in
this context. Generally any memory accesses will refer to entries in the caller's stack.
