forked from OSchip/llvm-project
Centralized all disassembly into static functions in source/Core/Disassembler.cpp.
Added the ability to read memory from the target's object files when we aren't running, so disassembling works before you run! Cleaned up the API to lldb_private::Target::ReadMemory(). Cleaned up the API to the Disassembler to use actual "lldb_private::Address" objects instead of just an "addr_t". This is nice because the Address objects when resolved carry along their section and module which can get us the object file. This allows Target::ReadMemory to be used when we are not running. Added a new lldb_private::Address dump style: DumpStyleDetailedSymbolContext This will show a full breakdown of what an address points to. To see some sample output, execute a "image lookup --address <addr>". Fixed SymbolContext::DumpStopContext(...) to not require a live process in order to be able to print function and symbol offsets. llvm-svn: 107350
