hitting auto-continue signals while running a thread plan would cause us to lose control of the debug
session.

Major fixed to allow reading files that are over 4GB. The main problems were that the DataExtractor was using 32 bit offsets as a data cursor, and since we mmap all of our object files we could run into cases where if we had a very large core file that was over 4GB, we were running into the 4GB boundary.
So I defined a new "lldb::offset_t" which should be used for all file offsets.
After making this change, I enabled warnings for data loss and for enexpected implicit conversions temporarily and found a ton of things that I fixed.
Any functions that take an index internally, should use "size_t" for any indexes and also should return "size_t" for any sizes of collections.

Added the ability for OS plug-ins to lazily populate the thread this. The python OS plug-in classes can now implement the following method:
class OperatingSystemPlugin:
def create_thread(self, tid, context):
# Return a dictionary for a new thread to create it on demand
This will add a new thread to the thread list if it doesn't already exist. The example code in lldb/examples/python/operating_system.py has been updated to show how this call us used.
Cleaned up the code in PythonDataObjects.cpp/h:
- renamed all classes that started with PythonData* to be Python*.
- renamed PythonArray to PythonList. Cleaned up the code to use inheritance where
- Centralized the code that does ref counting in the PythonObject class to a single function.
- Made the "bool PythonObject::Reset(PyObject *)" function be virtual so each subclass can correctly check to ensure a PyObject is of the right type before adopting the object.
- Cleaned up all APIs and added new constructors for the Python* classes to they can all construct form:
- PyObject *
- const PythonObject &
- const lldb::ScriptInterpreterObjectSP &
Cleaned up code in ScriptInterpreterPython:
- Made calling python functions safer by templatizing the production of value formats. Python specifies the value formats based on built in C types (long, long long, etc), and code often uses typedefs for uint32_t, uint64_t, etc when passing arguments down to python. We will now always produce correct value formats as the templatized code will "do the right thing" all the time.
- Fixed issues with the ScriptInterpreterPython::Locker where entering the session and leaving the session had a bunch of issues that could cause the "lldb" module globals lldb.debugger, lldb.target, lldb.process, lldb.thread, and lldb.frame to not be initialized.

Adding FindFirstGlobalVariable to SBModule and SBTarget
These calls work like FindGlobalVariables but they only return the first match found and so they can return an SBValue instead of an SBValueList for added convenience of use
llvm-svn: 172636
Added a unique integer identifier to processes. Some systems, like JTAG or other simulators, might always assign the same process ID (pid) to the processes that are being debugged. In order for scripts and the APIs to uniquely identify the processes, there needs to be another ID. Now the SBProcess class has:
uint32_t SBProcess::GetUniqueID();
This integer ID will help to truly uniquely identify a process and help with appropriate caching that can be associated with a SBProcess object.
llvm-svn: 172628
controlled by the --unwind-on-error flag, and --ignore-breakpoint which separately controls behavior when a called
function hits a breakpoint. For breakpoints, we don't unwind, we either stop, or ignore the breakpoint, which makes
more sense.
Also make both these behaviors globally settable through "settings set".
Also handle the case where a breakpoint command calls code that ends up re-hitting the breakpoint. We were recursing
and crashing. Now we just stop without calling the second command.
<rdar://problem/12986644>
<rdar://problem/9119325>
llvm-svn: 172503
Added SBTarget::EvaluateExpression() so expressions can be evaluated without needing a process.
Also fixed many functions that deal with clang AST types to be able to properly handle the clang::Type::Elaborated types ("struct foo", "class bar").
llvm-svn: 171476
Added a "step-in-target" flag to "thread step-in" so if you have something like:
Process 28464 stopped
* thread #1: tid = 0x1c03, function: main , stop reason = breakpoint 1.1
frame #0: 0x0000000100000e08 a.out`main at main.c:62
61
-> 62 int A6 = complex (a(4), b(5), c(6)); // Stop here to step targetting b and hitting breakpoint.
63
and you want to get into "complex" skipping a, b and c, you can do:
(lldb) step -t complex
Process 28464 stopped
* thread #1: tid = 0x1c03, function: complex , stop reason = step in
frame #0: 0x0000000100000d0d a.out`complex at main.c:44
41
42 int complex (int first, int second, int third)
43 {
-> 44 return first + second + third; // Step in targetting complex should stop here
45 }
46
47 int main (int argc, char const *argv[])
llvm-svn: 170008
Add the ability to get a symbol or symbols by name and type from a SBModule, and also the ability to get all symbols by name and type from SBTarget objects.
llvm-svn: 169205
Added a new API call to help efficiently determine if a SBValue could have children:
bool
SBValue::MightHaveChildren ();
This is inteneded to be used bui GUI programs that need to show if a SBValue needs a disclosure triangle when displaying a hierarchical type in a tree view without having to complete the type (by calling SBValue::GetNumChildren()) as completing the type is expensive.
llvm-svn: 166460
Given our implementation of ValueObjects we could have a scenario where a ValueObject has a dynamic type of Foo* at one point, and then its dynamic type changes to Bar*
If Bar* has synthetic children enabled, by the time we figure that out, our public API is already vending SBValues wrapping a DynamicVO, instead of a SyntheticVO and there was
no trivial way for us to change the SP inside an SBValue on the fly
This checkin reimplements SBValue in terms of a wrapper, ValueImpl, that allows this substitutions on-the-fly by overriding GetSP() to do The Right Thing (TM)
As an additional bonus, GetNonSyntheticValue() now works, and we can get rid of the ForceDisableSyntheticChildren idiom in ScriptInterpreterPython
Lastly, this checkin makes sure the synthetic VOs get the correct m_value and m_data from their parents (prevented summaries from working in some cases)
llvm-svn: 166426
Then make the Thread a Broadcaster, and get it to broadcast when the selected frame is changed (but only from the Command Line) and when Thread::ReturnFromFrame
changes the stack.
Made the Driver use this notification to print the new thread status rather than doing it in the command.
Fixed a few places where people were setting their broadcaster class by hand rather than using the static broadcaster class call.
<rdar://problem/12383087>
llvm-svn: 165640
This checkin adds the capability for LLDB to load plugins from external dylibs that can provide new commands
It exports an SBCommand class from the public API layer, and a new SBCommandPluginInterface
There is a minimal load-only plugin manager built into the debugger, which can be accessed via Debugger::LoadPlugin.
Plugins are loaded from two locations at debugger startup (LLDB.framework/Resources/PlugIns and ~/Library/Application Support/LLDB/PlugIns) and more can be (re)loaded via the "plugin load" command
For an example of how to make a plugin, refer to the fooplugin.cpp file in examples/plugins/commands
Caveats:
Currently, the new API objects and features are not exposed via Python.
The new commands can only be "parsed" (i.e. not raw) and get their command line via a char** parameter (we do not expose our internal Args object)
There is no unloading feature, which can potentially lead to leaks if you overwrite the commands by reloading the same or different plugins
There is no API exposed for option parsing, which means you may need to use getopt or roll-your-own
llvm-svn: 164865
- Tweaked a parameter name in SBDebugger.h so my typemap will catch it;
- Added a SBDebugger.Create(bool, callback, baton) to the swig interface;
- Added SBDebugger.SetLoggingCallback to the swig interface;
- Added a callback utility function for log callbacks;
- Guard against Py_None on both callback utility functions;
- Added a FIXME to the SBDebugger API test;
- Added a __del__() stub for SBDebugger.
We need to be able to get both the log callback and baton from an
SBDebugger if we want to protect against memory leaks (or make the user
responsible for holding another reference to the callback).
Additionally, it's impossible to revert from a callback-backed log
mechanism to a file-backed log mechanism.
llvm-svn: 162633
Added new API to lldb::SBTypeMember for bitfields:
bool SBTypeMember::IsBitfield();
uint32_t SBTypeMember::GetBitfieldSizeInBits();
Also added new properties for easy access. Now SBTypeMember objects in python have a "fields" property for all type fields, "bases" for all direct bases, "vbases" for all virtual base classes and "members" for a combo of all three organized by bit offset. They all return a python list() of SBTypeMember objects. Usage:
(lldb) script
>>> t = lldb.target.FindFirstType("my_type")
>>> for field in t.fields:
... print field
>>> for vbase in t.vbases:
... print vbase
>>> for base in t.bases:
... print base
>>> for member in t.members:
... print member
Also added new "is_bitfield" property to the SBTypeMember objects that will return the result of SBTypeMember::IsBitfield(), and "bitfield_bit_size" which will return the result of SBTypeMember::GetBitfieldSizeInBits();
I also fixed "SBTypeMember::GetOffsetInBytes()" to return the correct byte offset.
llvm-svn: 161091
Convert from calling Halt in the lldb Driver.cpp's input reader's sigint handler to sending this AsyncInterrupt so it can be handled in the
event loop.
If you are attaching and get an async interrupt, abort the attach attempt.
Also remember to destroy the process if get interrupted while attaching.
Getting this to work also required handing the eBroadcastBitInterrupt in a few more places in Process WaitForEvent & friends.

Execute which was never going to get run and another ExecuteRawCommandString. Took the knowledge of how
to prepare raw & parsed commands out of CommandInterpreter and put it in CommandObject where it belongs.
Also took all the cases where there were the subcommands of Multiword commands declared in the .h file for
the overall command and moved them into the .cpp file.
Made the CommandObject flags work for raw as well as parsed commands.
Made "expr" use the flags so that it requires you to be paused to run "expr".
llvm-svn: 158235
Refactorings of watchpoint creation APIs so that SBTarget::WatchAddress(), SBValue::Watch(), and SBValue::WatchPointee()
now take an additional 'SBError &error' parameter (at the end) to contain the reason if there is some failure in the
operation. Update 'watchpoint set variable/expression' commands to take advantage of that.
Update existing test cases to reflect the API change and add test cases to verify that the SBError mechanism works for
SBTarget::WatchAddress() by passing an invalid watch_size.
llvm-svn: 157964
Also changed the defaults for SBThread::Step* to not delete extant plans.
Also added some test cases to test more complex stepping scenarios.
llvm-svn: 156667
Switch over to the "*-apple-macosx" for desktop and "*-apple-ios" for iOS triples.
Also make the selection process for auto selecting platforms based off of an arch much better.
llvm-svn: 156354
A new setting enable-synthetic-value is provided on the target to disable this behavior.
There also is a new GetNonSyntheticValue() API call on SBValue to go back from synthetic to non-synthetic. There is no call to go from non-synthetic to synthetic.
The test suite has been changed accordingly.
Fallout from changes to type searching: an hack has to be played to make it possible to use maps that contain std::string due to the special name replacement operated by clang
Fixing a test case that was using libstdcpp instead of libc++ - caught as a consequence of said changes to type searching
llvm-svn: 153495
Adding a test case that checks that we do not complete types before due time. This should help us track cases similar to the cascading data formatters.
llvm-svn: 153363
This was done in SBTarget:
lldb::SBInstructionList
lldb::SBTarget::ReadInstructions (lldb::SBAddress base_addr, uint32_t count);
Also cleaned up a few files in the LLDB.framework settings.
llvm-svn: 152152
Add SBFrame::IsEqual(const SBFrame &that) method and export it to the Python binding.
Alos add a test case test_frame_api_IsEqual() to TestFrames.py file.
llvm-svn: 152050
fixed a few potential NULL-pointer derefs in ValueObject
we have a way to provide docstrings for properties we add to the SWIG layer - a few of these properties have a docstring already, more will come in future commits
added a new bunch of properties to SBData to make it more natural and Python-like to access the data they contain
llvm-svn: 151962
will fill out either a SBLaunchInfo or SBAttachInfo class, then call:
SBProcess SBTarget::Launch (SBLaunchInfo &, SBError &);
SBProcess SBTarget::Attach (SBAttachInfo &, SBError &);
The attach is working right now and allows the ability to set many filters such
as the parent process ID, the user/group ID, the effective user/group ID, and much
more.
The launch is not yet working, but I will get this working soon. By changing our
launch and attach calls to take an object, it allows us to add more capabilities to
launching and attaching without having to have launch and attach functions that
take more and more arguments.
Once this is all working we will deprecated the older launch and attach fucntions
and eventually remove them.
llvm-svn: 151344
subclasses if the object files support version numbering. Exposed
this through SBModule for upcoming data formatter version checking stuff.
llvm-svn: 151190
Adding new API calls to SBValue to be able to retrieve the associated formatters
Some refactoring to FormatNavigator::Get() in order to shrink its size down to more manageable terms (a future, massive, refactoring effort will still be needed)
Test cases added for the above
llvm-svn: 150784
New public API for handling formatters: creating, deleting, modifying categories, and formatters, and managing type/formatter association.
This provides SB classes for each of the main object types involved in providing formatter support:
SBTypeCategory
SBTypeFilter
SBTypeFormat
SBTypeSummary
SBTypeSynthetic
plus, an SBTypeNameSpecifier class that is used on the public API layer to abstract the notion that formatters can be applied to plain type-names as well as to regular expressions
For naming consistency, this patch also renames a lot of formatters-related classes.
Plus, the changes in how flags are handled that started with summaries is now extended to other classes as well. A new enum (lldb::eTypeOption) is meant to support this on the public side.
The patch also adds several new calls to the formatter infrastructure that are used to implement by-index accessing and several other design changes required to accommodate the new API layer.
An architectural change is introduced in that backing objects for formatters now become writable. On the public API layer, CoW is implemented to prevent unwanted propagation of changes.
Lastly, there are some modifications in how the "default" category is constructed and managed in relation to other categories.
llvm-svn: 150558
interface (.i) files for each class.
Changed the FindFunction class from:
uint32_t
SBTarget::FindFunctions (const char *name,
uint32_t name_type_mask,
bool append,
lldb::SBSymbolContextList& sc_list)
uint32_t
SBModule::FindFunctions (const char *name,
uint32_t name_type_mask,
bool append,
lldb::SBSymbolContextList& sc_list)
To:
lldb::SBSymbolContextList
SBTarget::FindFunctions (const char *name,
uint32_t name_type_mask = lldb::eFunctionNameTypeAny);
lldb::SBSymbolContextList
SBModule::FindFunctions (const char *name,
uint32_t name_type_mask = lldb::eFunctionNameTypeAny);
This makes the API easier to use from python. Also added the ability to
append a SBSymbolContext or a SBSymbolContextList to a SBSymbolContextList.
Exposed properties for lldb.SBSymbolContextList in python:
lldb.SBSymbolContextList.modules => list() or all lldb.SBModule objects in the list
lldb.SBSymbolContextList.compile_units => list() or all lldb.SBCompileUnits objects in the list
lldb.SBSymbolContextList.functions => list() or all lldb.SBFunction objects in the list
lldb.SBSymbolContextList.blocks => list() or all lldb.SBBlock objects in the list
lldb.SBSymbolContextList.line_entries => list() or all lldb.SBLineEntry objects in the list
lldb.SBSymbolContextList.symbols => list() or all lldb.SBSymbol objects in the list
This allows a call to the SBTarget::FindFunctions(...) and SBModule::FindFunctions(...)
and then the result can be used to extract the desired information:
sc_list = lldb.target.FindFunctions("erase")
for function in sc_list.functions:
print function
for symbol in sc_list.symbols:
print symbol
Exposed properties for the lldb.SBSymbolContext objects in python:
lldb.SBSymbolContext.module => lldb.SBModule
lldb.SBSymbolContext.compile_unit => lldb.SBCompileUnit
lldb.SBSymbolContext.function => lldb.SBFunction
lldb.SBSymbolContext.block => lldb.SBBlock
lldb.SBSymbolContext.line_entry => lldb.SBLineEntry
lldb.SBSymbolContext.symbol => lldb.SBSymbol
Exposed properties for the lldb.SBBlock objects in python:
lldb.SBBlock.parent => lldb.SBBlock for the parent block that contains
lldb.SBBlock.sibling => lldb.SBBlock for the sibling block to the current block
lldb.SBBlock.first_child => lldb.SBBlock for the first child block to the current block
lldb.SBBlock.call_site => for inline functions, return a lldb.declaration object that gives the call site file, line and column
lldb.SBBlock.name => for inline functions this is the name of the inline function that this block represents
lldb.SBBlock.inlined_block => returns the inlined function block that contains this block (might return itself if the current block is an inlined block)
lldb.SBBlock.range[int] => access the address ranges for a block by index, a list() with start and end address is returned
lldb.SBBlock.ranges => an array or all address ranges for this block
lldb.SBBlock.num_ranges => the number of address ranges for this blcok
SBFunction objects can now get the SBType and the SBBlock that represents the
top scope of the function.
SBBlock objects can now get the variable list from the current block. The value
list returned allows varaibles to be viewed prior with no process if code
wants to check the variables in a function. There are two ways to get a variable
list from a SBBlock:
lldb::SBValueList
SBBlock::GetVariables (lldb::SBFrame& frame,
bool arguments,
bool locals,
bool statics,
lldb::DynamicValueType use_dynamic);
lldb::SBValueList
SBBlock::GetVariables (lldb::SBTarget& target,
bool arguments,
bool locals,
bool statics);
When a SBFrame is used, the values returned will be locked down to the frame
and the values will be evaluated in the context of that frame.
When a SBTarget is used, global an static variables can be viewed without a
running process.
llvm-svn: 149853
Fixed "target modules list" (aliased to "image list") to output more information
by default. Modified the "target modules list" to have a few new options:
"--header" or "-h" => show the image header address
"--offset" or "-o" => show the image header address offset from the address in the file (the slide applied to the shared library)
Removed the "--symfile-basename" or "-S" option, and repurposed it to
"--symfile-unique" "-S" which will show the symbol file if it differs from
the executable file.
ObjectFile's can now be loaded from memory for cases where we don't have the
files cached locally in an SDK or net mounted root. ObjectFileMachO can now
read mach files from memory.
Moved the section data reading code into the ObjectFile so that the object
file can get the section data from Process memory if the file is only in
memory.
lldb_private::Module can now load its object file in a target with a rigid
slide (very common operation for most dynamic linkers) by using:
bool
Module::SetLoadAddress (Target &target, lldb::addr_t offset, bool &changed)
lldb::SBModule() now has a new constructor in the public interface:
SBModule::SBModule (lldb::SBProcess &process, lldb::addr_t header_addr);
This will find an appropriate ObjectFile plug-in to load an image from memory
where the object file header is at "header_addr".
llvm-svn: 149804
Changed the lldb.SBModule.section[<str>] property to return a single section.
Added a lldb.SBSection.addr property which returns an lldb.SBAddress object.
llvm-svn: 149755
lldb.SBValueList now exposes the len() method and also allows item access:
lldb.SBValueList[<int>] - where <int> is an integer index into the list, returns a single lldb.SBValue which might be empty if the index is out of range
lldb.SBValueList[<str>] - where <str> is the name to look for, returns a list() of lldb.SBValue objects with any matching values (the list might be empty if nothing matches)
lldb.SBValueList[<re>] - where <re> is a compiles regular expression, returns a list of lldb.SBValue objects for containing any matches or a empty list if nothing matches
lldb.SBFrame now exposes:
lldb.SBFrame.variables => SBValueList of all variables that are in scope
lldb.SBFrame.vars => see lldb.SBFrame.variables
lldb.SBFrame.locals => SBValueList of all variables that are locals in the current frame
lldb.SBFrame.arguments => SBValueList of all variables that are arguments in the current frame
lldb.SBFrame.args => see lldb.SBFrame.arguments
lldb.SBFrame.statics => SBValueList of all static variables
lldb.SBFrame.registers => SBValueList of all registers for the current frame
lldb.SBFrame.regs => see lldb.SBFrame.registers
Combine any of the above properties with the new lldb.SBValueList functionality
and now you can do:
y = lldb.frame.vars['rect.origin.y']
or
vars = lldb.frame.vars
for i in range len(vars):
print vars[i]
Also expose "lldb.SBFrame.var(<str>)" where <str> can be en expression path
for any variable or child within the variable. This makes it easier to get a
value from the current frame like "rect.origin.y". The resulting value is also
not a constant result as expressions will return, but a live value that will
continue to track the current value for the variable expression path.
lldb.SBValue now exposes:
lldb.SBValue.unsigned => unsigned integer for the value
lldb.SBValue.signed => a signed integer for the value
llvm-svn: 149684
uint32_t
SBType::GetNumberOfTemplateArguments ();
lldb::SBType
SBType::GetTemplateArgumentType (uint32_t idx);
lldb::TemplateArgumentKind
SBType::GetTemplateArgumentKind (uint32_t idx);
Some lldb::TemplateArgumentKind values don't have a corresponding SBType
that will be returned from SBType::GetTemplateArgumentType(). This will
help our data formatters do their job by being able to find out the
type of template params and do smart things with those.
llvm-svn: 149658
You can now access a frame in a thread using:
lldb.SBThread.frame[int] -> lldb.SBFrame object for a frame in a thread
Where "int" is an integer index. You can also access a list object with all of
the frames using:
lldb.SBThread.frames => list() of lldb.SBFrame objects
All SB objects that give out SBAddress objects have properties named "addr"
lldb.SBInstructionList now has the following convenience accessors for len() and
instruction access using an index:
insts = lldb.frame.function.instructions
for idx in range(len(insts)):
print insts[idx]
Instruction lists can also lookup an isntruction using a lldb.SBAddress as the key:
pc_inst = lldb.frame.function.instructions[lldb.frame.addr]
lldb.SBProcess now exposes:
lldb.SBProcess.is_alive => BOOL Check if a process is exists and is alive
lldb.SBProcess.is_running => BOOL check if a process is running (or stepping):
lldb.SBProcess.is_running => BOOL check if a process is currently stopped or crashed:
lldb.SBProcess.thread[int] => lldb.SBThreads for a given "int" zero based index
lldb.SBProcess.threads => list() containing all lldb.SBThread objects in a process
SBInstruction now exposes:
lldb.SBInstruction.mnemonic => python string for instruction mnemonic
lldb.SBInstruction.operands => python string for instruction operands
lldb.SBInstruction.command => python string for instruction comment
SBModule now exposes:
lldb.SBModule.uuid => uuid.UUID(), an UUID object from the "uuid" python module
lldb.SBModule.symbol[int] => lldb.Symbol, lookup symbol by zero based index
lldb.SBModule.symbol[str] => list() of lldb.Symbol objects that match "str"
lldb.SBModule.symbol[re] => list() of lldb.Symbol objecxts that match the regex
lldb.SBModule.symbols => list() of all symbols in a module
SBAddress objects can now access the current load address with the "lldb.SBAddress.load_addr"
property. The current "lldb.target" will be used to try and resolve the load address.
Load addresses can also be set using this accessor:
addr = lldb.SBAddress()
addd.load_addr = 0x123023
Then you can check the section and offset to see if the address got resolved.
SBTarget now exposes:
lldb.SBTarget.module[int] => lldb.SBModule from zero based module index
lldb.SBTarget.module[str] => lldb.SBModule by basename or fullpath or uuid string
lldb.SBTarget.module[uuid.UUID()] => lldb.SBModule whose UUID matches
lldb.SBTarget.module[re] => list() of lldb.SBModule objects that match the regex
lldb.SBTarget.modules => list() of all lldb.SBModule objects in the target
SBSymbol now exposes:
lldb.SBSymbol.name => python string for demangled symbol name
lldb.SBSymbol.mangled => python string for mangled symbol name or None if there is none
lldb.SBSymbol.type => lldb.eSymbolType enum value
lldb.SBSymbol.addr => SBAddress object that represents the start address for this symbol (if there is one)
lldb.SBSymbol.end_addr => SBAddress for the end address of the symbol (if there is one)
lldb.SBSymbol.prologue_size => pythin int containing The size of the prologue in bytes
lldb.SBSymbol.instructions => SBInstructionList containing all instructions for this symbol
SBFunction now also has these new properties in addition to what is already has:
lldb.SBFunction.addr => SBAddress object that represents the start address for this function
lldb.SBFunction.end_addr => SBAddress for the end address of the function
lldb.SBFunction.instructions => SBInstructionList containing all instructions for this function
SBFrame now exposes the SBAddress for the frame:
lldb.SBFrame.addr => SBAddress which is the section offset address for the current frame PC
These are all in addition to what was already added. Documentation and website
updates coming soon.
llvm-svn: 149489
(lldb) script
>>> frames = lldb.thread.frames
>>> for frame in frames:
... print frame
Also changed all of the "__repr__" methods to strip any trailing newline characters so we don't end up with entra newlines.
llvm-svn: 149466
We previously weren't catching that SBValue::Cast(...) would crash
if we had an invalid (empty) SBValue object.
Cleaned up the SBType API a bit.

Remove a pseudo terminal master open and slave file descriptor that was being
used for pythong stdin. It was not hooked up correctly and was causing file
descriptor leaks.
llvm-svn: 149098
as part of the thread format output.
Currently this is only done for the ThreadPlanStepOut.
Add a convenience API ABI::GetReturnValueObject.
Change the ValueObject::EvaluationPoint to BE an ExecutionContextScope, rather than
trying to hand out one of its subsidiary object's pointers. That way this will always
be good.
llvm-svn: 146806
Added a static memory pressure function in SBDebugger:
void SBDebugger::MemoryPressureDetected ()
This can be called by applications that detect memory pressure to cause LLDB to release cached information.
llvm-svn: 146640
size_t
SBProcess::ReadCStringFromMemory (addr_t addr, void *buf, size_t size, lldb::SBError &error);
uint64_t
SBProcess::ReadUnsignedFromMemory (addr_t addr, uint32_t byte_size, lldb::SBError &error);
lldb::addr_t
SBProcess::ReadPointerFromMemory (addr_t addr, lldb::SBError &error);
These ReadCStringFromMemory() has some SWIG type magic that makes it return the
python string directly and the "buf" is not needed:
error = SBError()
max_cstr_len = 256
cstr = lldb.process.ReadCStringFromMemory (0x1000, max_cstr_len, error)
if error.Success():
....
The other two functions behave as expteced. This will make it easier to get integer values
from the inferior process that are correctly byte swapped. Also for pointers, the correct
pointer byte size will be used.
Also cleaned up a few printf style warnings for the 32 bit lldb build on darwin.
llvm-svn: 146636
clients to disassemble a series of raw bytes as
demonstrated by a new testcase.
In the future, this API will also allow clients
