Greg Clayton 8c2afa0cd5 Improved the packet dumper to escape the response string before sending it to the response functions (find any 0x7d characters and remove it and XOR the next character with 0x20). This allows us to parse the JSON in the reply packet and display it correctly.

Jason Molenda 7a5014b040 Add a call to SBDebugger:Destroy() at the end of the self-hosted
version of this script.  We picked up a bug at some point in March
where scripts that fail to call SBDebugger::Destroy() will crash
in the Debugger C++ dtor.  I want to track the change down which
introduced the change - but this script should be calling
SBDebugger::Destroy() in the first place, so do that.

Greg Clayton 2f547177f8 Improved the TreeItem delegate which simplifies making tree items:
- tree items can define any number of key/value pairs
- creating a tree you specify which columns you want to display and it will pick out the right key/value pairs from the new tree item dictionaries
- added new "tk-target" command to explore the target's images, sections, symbols, compile units and line tables.

Greg Clayton 994ba64756 Played around with TK UI a bit this weekend.
If you "command script import" this file, then you will have two new commands:

(lldb) tk-variables
(lldb) tk-process

Not sure how this will work on all other systems, but on MacOSX, you will get a window with a tree view that allows you to inspect your local variables by expanding variables to see the child values.

The "tk-process" allows you to inspect the currently selected process by expanding the process to see the threads, the threads to see the frames, and the frames to see the variables. Very handy if you want to view variables for all frames simultaneously.

Greg Clayton 641c23f332 Allow classes to be intialized using current lldb::SB objects. This can help to import/export the current process state.
llvm-svn: 209702
2014-05-28 00:21:15 +00:00
Greg Clayton 86e70cb3ac Fixed an issue where if you called:
SBTarget::AddModule(const char *path,
                    const char *triple,
                    const char *uuid_cstr,
                    const char *symfile);
                    
If "symfile" was filled in, it would cause us to not correctly add the module. Same goes for:

SBTarget::AddModule(SBModuleSpec ...)

Where you filled in the symfile.

Hafiz Abid Qadeer 85a4daf4f6 Adjust PC after hitting breakpoint on remote target.
This commit adds an example python file that can be used with 'target-definition-file' setting for Linux gdbserver.
This file has an extra key 'breakpoint-pc-offset' that LLDB uses to determine how much to change the PC
after hitting the breakpoint.

Greg Clayton 312bcbe8b4 <rdar://problem/14972424>
- Made the dynamic register context for the GDB remote plug-in inherit from the generic DynamicRegisterInfo to avoid code duplication
- Finished up the target definition python setting stuff.
- Added a new "slice" key/value pair that can specify that a register is part of another register:
    { 'name':'eax', 'set':0, 'bitsize':32, 'encoding':eEncodingUint, 'format':eFormatHex, 'slice': 'rax[31:0]' },
- Added a new "composite" key/value pair that can specify that a register is made up of two or more registers:
    { 'name':'d0', 'set':0, 'bitsize':64 , 'encoding':eEncodingIEEE754, 'format':eFormatFloat, 'composite': ['s1', 's0'] },
- Added a new "invalidate-regs" key/value pair for when a register is modified, it can invalidate other registers:
    { 'name':'cpsr', 'set':0, 'bitsize':32 , 'encoding':eEncodingUint, 'format':eFormatHex, 'invalidate-regs': ['r8', 'r9', 'r10', 'r11', 'r12', 'r13', 'r14', 'r15']},
    
This now completes the feature that allows a GDB remote target to completely describe itself.

Greg Clayton ef8180a3f6 <rdar://problem/14972424>
When debugging with the GDB remote in LLDB, LLDB uses special packets to discover the
registers on the remote server. When those packets aren't supported, LLDB doesn't
know what the registers look like. This checkin implements a setting that can be used
to specify a python file that contains the registers definitions. The setting is:

(lldb) settings set plugin.process.gdb-remote.target-definition-file /path/to/module.py

Inside module there should be a function:

def get_dynamic_setting(target, setting_name):

This dynamic setting function is handed the "target" which is a SBTarget, and the 
"setting_name", which is the name of the dynamic setting to retrieve. For the GDB
remote target definition the setting name is 'gdb-server-target-definition'. The
return value is a dictionary that follows the same format as the OperatingSystem
plugins follow. I have checked in an example file that implements the x86_64 GDB
register set for people to see:

    examples/python/x86_64_target_definition.py
    
This allows LLDB to debug to any archticture that is support and allows users to
define the registers contexts when the discovery packets (qRegisterInfo, qHostInfo)
are not supported by the remote GDB server.

A few benefits of doing this in Python:
1 - The dynamic register context was already supported in the OperatingSystem plug-in
2 - Register contexts can use all of the LLDB enumerations and definitions for things
    like lldb::Format, lldb::Encoding, generic register numbers, invalid registers 
    numbers, etc.
3 - The code that generates the register context can use the program to calculate the
    register context contents (like offsets, register numbers, and more)
4 - True dynamic detection could be used where variables and types could be read from 
    the target program itself in order to determine which registers are available since
    the target is passed into the python function.
    
This is designed to be used instead of XML since it is more dynamic and code flow and
functions can be used to make the dictionary.

Greg Clayton 6a23d21289 Added a "sources.py" which adds a command that can print out the source files contained in one or more modules.
Added "mach_o.py" which is a mach-o parser that can dump mach-o file contents and also extract sections. It uses the "file_extract" module and the "dict_utils" module.

Jason Molenda 5bd4a4613c Add new information gathering to the lldb & simple backtrace methods:

Greg Clayton d8c3d4b1e9 Implemented a types.py module that allows types to be inspected for padding.
The script was able to point out and save 40 bytes in each lldb_private::Section by being very careful where we need to have virtual destructors and also by re-ordering members.

Jason Molenda 8359214427 A few small enhancements to the diagnose-unwind command.
Change the simple-minded stack walk to not depend on lldb to unwind
the first frame.

Collect a list of Modules and Addresses seen while backtracing (with
both methods), display the image list output for all of those modules,
plus disassemble and image show-unwind any additional frames that
the simple backtrace was able to unwind through instead of just the 
lldb unwind algorithm frames.

Remove checks for older lldb's that didn't support -a for disassemble
or specifying the assembler syntax on x86 targets.
