watchpoint modify -c 'global==5'
modifies the last created watchpoint so that the condition expression
is evaluated at the stop point to decide whether we should proceed with
the stopping.
Also add SBWatchpont::SetCondition(const char *condition) to set condition
programmatically.
Test cases to come later.

Set up self.lldbOption to be "--no-lldbibit" unless env variable NO_LLDBIBIT is defined and equals "NO".
Also add "-nx" to gdb spawned.

when newly created threads were subsequently stopped due to breakpoint hit.
The stop-hook mechanism delegates to CommandInterpreter::HandleCommands() to
execuet the commands. Make sure the execution context is switched only once
at the beginning of HandleCommands() only and don't update the context while looping
on each individual command to be executed.

Add a keyword argument 'endstr' to TestBase.expect() method to assert that the output
will end with 'endstr'.
Add TestBase.switch_to_thread_with_stop_reason(stop_reason) to select the thread with
the stop reason = 'stop_reason' as the current thread.
o TestWatchLocation.py:
Modified to switch to the stopped thread with stop reason = watchpoint and to evaluate
an expression with expected output for stronger assertion.

the watchpoint state is changed, not only does the change propagate to all the thread instances,
it also updates a global debug state, if chosen by the DNBArchProtocol derivative.
Once implemented, the DNBArchProtocol derivative, also makes sure that when new thread comes along,
it tries to inherit from the global debug state, if it is valid.
Modify TestWatchpointMultipleThreads.py to test this functionality.
llvm-svn: 140811
it enables the hardware watchpoint for all existing threads. Add a test file for that.
Also fix MachThreadList::DisableHardwareWatchpoint().
llvm-svn: 140757
too long, so that the jump from the line above the bad line to the line after
ends up in the middle of the bad line instead. Added a workaround to lldb to just
continue to the end if we find ourselves stopped in the middle of some other line.
llvm-svn: 140419
etc to specific source files.
Added SB API's to specify these source files & also more than one module.
Added an "exact" option to CompileUnit's FindLineEntry API.
llvm-svn: 140362
it to generate result variables that were not bound
to their underlying data. This allowed the SBValue
class to use the interpreter (if possible).
Also made sure that any result variables that point
to stack allocations in the stack frame of the
interpreted expressions do not get live data.
llvm-svn: 140285
Modify CommandObjectFrame.cpp to populate this field when creating a watchpoint location.
Update the test case to verify that the declaration info matches the file and line number.

--show-aliases (-a) shows aliases for commands, as well as built-in commands
--hide-user-defined (-u) hides user defined commands
by default 'help' without arguments does not show aliases anymore. to see them, add --show-aliases
to have only built-in commands appear, use 'help --hide-user-defined' ; there is currently no way to hide
built-in commands from the help output
'help command' is not changed by this commit, and help is shown even if command is an alias and -a is not specified
llvm-svn: 139377
Set the default Source File & line to main (if it can be found.) at startup. Selecting the current thread & or frame resets
the current source file & line, and "source list" as well as the breakpoint command "break set -l <NUM>" will use the
current source file.

- introduced two new classes ValueObjectConstResultChild and ValueObjectConstResultImpl: the first one is a ValueObjectChild obtained from
a ValueObjectConstResult, the second is a common implementation backend for VOCR and VOCRCh of method calls meant to read through pointers stored
in frozen objects ; now such reads transparently move from host to target as required
- as a consequence of the above, removed code that made target-memory copies of expression results in several places throughout LLDB, and also
removed code that enabled to recognize an expression result VO as such
- introduced a new GetPointeeData() method in ValueObject that lets you read a given amount of objects of type T from a VO
representing a T* or T[], and doing dereferences transparently
in private layer it returns a DataExtractor ; in public layer it returns an instance of a newly created lldb::SBData
- as GetPointeeData() does the right thing for both frozen and non-frozen ValueObject's, reimplemented ReadPointedString() to use it
en lieu of doing the raw read itself
- introduced a new GetData() method in ValueObject that lets you get a copy of the data that backs the ValueObject (for pointers,
this returns the address without any previous dereferencing steps ; for arrays it actually reads the whole chunk of memory)
in public layer this returns an SBData, just like GetPointeeData()
- introduced a new CreateValueFromData() method in SBValue that lets you create a new SBValue from a chunk of data wrapped in an SBData
the limitation to remember for this kind of SBValue is that they have no address: extracting the address-of for these objects (with any
of GetAddress(), GetLoadAddress() and AddressOf()) will return invalid values
- added several tests to check that "p"-ing objects (STL classes, char* and char[]) will do the right thing
Solved a bug where global pointers to global variables were not dereferenced correctly for display
New target setting "max-string-summary-length" gives the maximum number of characters to show in a string when summarizing it, instead of the hardcoded 128
Solved a bug where the summary for char[] and char* would not be shown if the ValueObject's were dumped via the "p" command
Removed m_pointers_point_to_load_addrs from ValueObject. Introduced a new m_address_type_of_children, which each ValueObject can set to tell the address type
of any pointers and/or references it creates. In the current codebase, this is load address most of the time (the only notable exception being file
addresses that generate file address children UNLESS we have a live process)
Updated help text for summary-string
Fixed an issue in STL formatters where std::stlcontainer::iterator would match the container's synthetic children providers
Edited the syntax and help for some commands to have proper argument types
llvm-svn: 139160
built locally from the source tree. This is distinguished from self.lldbExec, which
can be used by test/benchmarks to measure the performances against other debuggers.
You can use environment variable LLDB_EXEC to specify self.lldbExec to the dotest.py
test driver, otherwise it is going to be populated with self.lldbHere.
Modify the regular tests under test dir, i.e., not test/benchmarks, to use self.lldbHere.
Also modify the benchmarks tests to use self.lldbHere when it needs an 'lldb' executable
with debug info to do the performance measurements.
llvm-svn: 138608
Renamed format "signed decimal" to be "decimal". "unsigned decimal" remains unchanged:
- the name "signed decimal" was interfering with symbol %S (use summary) in summary strings.
because of the way summary strings are implemented, this did not really lead to a bug, but
simply to performing more steps than necessary to display a summary. this is fixed.
Documentation improvements (more on synthetic children, some information on filters). This is still a WIP.

If you have a Python module foo, in order to use its contained objects in LLDB you do not need to use
'from foo import *'. You can use 'import foo', and then refer to items in foo as 'foo.bar', and LLDB
will know how to resolve bar as a member of foo.
Accordingly, GNU libstdc++ formatters have been moved from the global namespace to gnu_libstdcpp and a few
test cases are also updated to reflect the new convention. Python docs suggest using a plain 'import' en lieu of
'from-import'.
llvm-svn: 138244
e.g. you may get "foo_class @ 0x123456" when typing "type summary add -f ${var} foo_class"
- Added a new special formatting token %T for summaries. This shows the type of the object.
Using it, the new "type @ location" summary could be manually generated by writing ${var%T} @ ${var%L}
- Bits and pieces required to support "frame variable array[n-m]"
The feature is not enabled yet because some additional design and support code is required, but the basics
are getting there
- Fixed a potential issue where a ValueObjectSyntheticFilter was not holding on to its SyntheticChildrenSP
Because of the way VOSF are being built now, this has never been an actual issue, but it is still sensible for
a VOSF to hold on to the SyntheticChildrenSP as well as to its FrontEnd
llvm-svn: 138080
- reorganizing the PTS (Partial Template Specializations) in FormatManager.h
- applied a patch by Filipe Cabecinhas to make LLDB compile with GCC
Functional changes:
- fixed an issue where command type summary add for type "struct Foo" would not match any types.
currently, "struct" will be stripped off and type "Foo" will be matched.
similar behavior occurs for class, enum and union specifiers.
llvm-svn: 138020
- reorganizing classes layout to have public part first
Typedefs that we want to keep private, but must be defined for some public code to work correctly are an exception
- avoiding methods in the form T foo() { code; } all on one-line
- moving method implementations from .h to .cpp whenever feasible
Templatized code is an exception and so are very small methods
- generally, adhering to coding conventions followed project-wide
Functional changes:
- fixed an issue where using ${var} in a summary for an aggregate, and then displaying a pointer-to-aggregate would lead to no summary being displayed
The issue was not a major one because all ${var} was meant to do in that context was display an error for invalid use of pointer
Accordingly fixed test cases and added a new test case
llvm-svn: 137944
- all instances of "vobj" have been renamed to "valobj"
- class Debugger::Formatting has been renamed to DataVisualization (defined in FormatManager.h/cpp)
The interface to this class has not changed
- FormatCategory now uses ConstString's as keys to the navigators instead of repeatedly casting
from ConstString to const char* and back all the time
Next step is making the same happen for categories themselves
- category gnu-libstdc++ is defined in the constructor for a FormatManager
The source code for it is defined in gnu_libstdcpp.py, drawn from examples/synthetic at compile time
All references to previous 'osxcpp' name have been removed from both code and file names
Functional changes:
- the name of the option to use a summary string for 'type summary add' has changed from the previous --format-string
to the new --summary-string. It is expected that the short option will change from -f to -s, and -s for --python-script
will become -o
llvm-svn: 137886
The category is enabled by default. If you run into issues with it, disable it and the previous behavior of LLDB is restored
** This is a temporary solution. The general solution to having formatters pulled in at startup should involve going through the Platform.
Fixed an issue in type synthetic list where a category with synthetic providers in it was not shown if all the providers were regex-based
llvm-svn: 137850
If no docstring is provided, a default help text is created
LLDB will refuse to create scripted commands if the scripting language is anything but Python
Some additional comments in AppleObjCRuntimeV2.cpp to describe the memory layout expected by the dynamic type lookup code
llvm-svn: 137801
- They now have an SBCommandReturnObject instead of an SBStream as third argument
- The class CommandObjectPythonFunction has been merged into CommandObjectCommands.cpp
- The command to manage them is now:
command script with subcommands add, list, delete, clear
command alias is returned to its previous functionality
- Python commands are now part of an user dictionary, instead of being seen as aliases
llvm-svn: 137785
It is now possible to use 'command alias --python' to define a command name that actually triggers execution of a Python function
(e.g. command alias --python foo foo_impl makes a command named 'foo' that runs Python function 'foo_impl')
The Python function foo_impl should have as signature: def foo_impl(debugger, args, stream, dict): where
debugger is an object wrapping an LLDB SBDebugger
args is the command line arguments, as an unparsed Python string
stream is an SBStream that represents the standard output
dict is an internal utility parameter and should be left untouched
The function should return None on no error, or an error string to describe any problems
