The r117616 check in broken these two test cases: 1. FoundationDisassembleTestCase.test_simple_disasm_with_dsym; and 2. FoundationDisassembleTestCase.test_simple_disasm_with_dwarf the reason being the test was issuing 'disassemble' command to disassemble the current frame function when stopped. The 'disassemble' command worked previously but it was a result of bad option specification.

Fixed the way set/show variables were being accessed to being natively accessed by the objects that own the settings. The previous approach wasn't very usable and made for a lot of unnecessary code just to access variables that were already owned by the objects. While I fixed those things, I saw that CommandObject objects should really have a reference to their command interpreter so they can access the terminal with if they want to output usaage. Fixed up all CommandObjects to take an interpreter and cleaned up the API to not need the interpreter to be passed in. Fixed the disassemble command to output the usage if no options are passed down and arguments are passed (all disassebmle variants take options, there are no "args only"). llvm-svn: 114252

Abtracted all mach-o and ELF out of ArchSpec. This patch is a modified form of Stephen Wilson's idea (thanks for the input Stephen!). What I ended up doing was: - Got rid of ArchSpec::CPU (which was a generic CPU enumeration that mimics the contents of llvm::Triple::ArchType). We now rely upon the llvm::Triple to give us the machine type from llvm::Triple::ArchType. - There is a new ArchSpec::Core definition which further qualifies the CPU core we are dealing with into a single enumeration. If you need support for a new Core and want to debug it in LLDB, it must be added to this list. In the future we can allow for dynamic core registration, but for now it is hard coded. - The ArchSpec can now be initialized with a llvm::Triple or with a C string that represents the triple (it can just be an arch still like "i386"). - The ArchSpec can still initialize itself with a architecture type -- mach-o with cpu type and subtype, or ELF with e_machine + e_flags -- and this will then get translated into the internal llvm::Triple::ArchSpec + ArchSpec::Core. The mach-o cpu type and subtype can be accessed using the getter functions: uint32_t ArchSpec::GetMachOCPUType () const; uint32_t ArchSpec::GetMachOCPUSubType () const; But these functions are just converting out internal llvm::Triple::ArchSpec + ArchSpec::Core back into mach-o. Same goes for ELF. All code has been updated to deal with the changes. This should abstract us until later when the llvm::TargetSpec stuff gets finalized and we can then adopt it. llvm-svn: 126278

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

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

if (m_options.show_mixed && m_options.num_lines_context == 0)
Fixed a missing newline when dumping mixed disassembly. Added a "bool show_fullpaths" to many more objects that were previously always dumping full paths. Fixed a few places where the DWARF was not indexed when we we needed it to be when making queries. Also fixed an issue where the DWARF in .o files wasn't searching all .o files for the types. Fixed an issue with the output from "image lookup --type <TYPENAME>" where the name and byte size might not be resolved and might not display. We now call the accessors so we end up seeing all of the type info. llvm-svn: 113951

ConstString name(m_options.m_func_name.c_str());
Fixed the way set/show variables were being accessed to being natively accessed by the objects that own the settings. The previous approach wasn't very usable and made for a lot of unnecessary code just to access variables that were already owned by the objects. While I fixed those things, I saw that CommandObject objects should really have a reference to their command interpreter so they can access the terminal with if they want to output usaage. Fixed up all CommandObjects to take an interpreter and cleaned up the API to not need the interpreter to be passed in. Fixed the disassemble command to output the usage if no options are passed down and arguments are passed (all disassebmle variants take options, there are no "args only"). llvm-svn: 114252
