break set -l c++ -r Name

for "break set -n" and there are SB API's to pass this as well.

Target and breakpoints options were added:
breakpoint set --language lang --name func
settings set target.language pascal
These specify the Language to use when interpreting the breakpoint's
expression (note: currently only implemented for breakpoints on
identifiers). If the breakpoint language is not set, the target.language
setting is used.
This support is required by Pascal, for example, to set breakpoint at 'ns.foo'
for function 'foo' in namespace 'ns'.
Tests on the language were also added to Module::PrepareForFunctionNameLookup
for efficiency.

Since interaction with the python interpreter is moving towards
being more isolated, we won't be able to include this header from
normal files anymore, all includes of it should be localized to
the python library which will live under source/bindings/API/Python

support to LLDB. It includes the following:
- Changed DeclVendor to TypeVendor.
- Made the ObjCLanguageRuntime provide a DeclVendor
rather than a TypeVendor.
- Changed the consumers of TypeVendors to use
DeclVendors instead.
- Provided a few convenience functions on
ClangASTContext to make that easier.
llvm-svn: 223433
Fixed include:
- Change Platform::ResolveExecutable(...) to take a ModuleSpec instead of a FileSpec + ArchSpec to help resolve executables correctly when we have just a path + UUID (no arch).
- Add the ability to set the listener in SBLaunchInfo and SBAttachInfo in case you don't want to use the debugger as the default listener.
- Modified all places that use the SBLaunchInfo/SBAttachInfo and the internal ProcessLaunchInfo/ProcessAttachInfo to not take a listener as a parameter since it is in the launch/attach info now
- Load a module's sections by default when removing a module from a target. Since we create JIT modules for expressions and helper functions, we could end up with stale data in the section load list if a module was removed from the target as the section load list would still have entries for the unloaded module. Target now has the following functions to help unload all sections a single or multiple modules:
size_t
Target::UnloadModuleSections (const ModuleList &module_list);
size_t
Target::UnloadModuleSections (const lldb::ModuleSP &module_sp);
llvm-svn: 222167
The problem was that SBTarget::ReadMemory() was making a new section offset lldb_private::Address by doing:
size_t
SBTarget::ReadMemory (const SBAddress addr,
void *buf,
size_t size,
lldb::SBError &error)
{
...
lldb_private::Address addr_priv(addr.GetFileAddress(), NULL);
bytes_read = target_sp->ReadMemory(addr_priv, false, buf, size, err_priv);
This is wrong. If you get the file addresss from the "addr" argument and try to read memory using that, it will think the file address is a load address and it will try to resolve it accordingly. This will work fine if your executable is loaded at the same address (no slide), but it won't work if there is a slide.
The fix is to just pass along the "addr.ref()" instead of making a new addr_priv as this will pass along the lldb_private::Address that is inside the SBAddress (which is what we want), and not always change it into something that becomes a load address (if we are running), or abmigious file address (think address zero when you have 150 shared libraries that have sections that start at zero, which one would you pick). The main reason for passing a section offset address to SBTarget::ReadMemory() is so you _can_ read from the actual section + offset that is specified in the SBAddress.
llvm-svn: 221213
New functions to give client applications to tools to discover target byte sizes
for addresses prior to ReadMemory. Also added GetPlatform and ReadMemory to the
SBTarget class, since they seemed to be useful utilities to have.
Each new API has had a test case added.

This commit reimplements the TypeImpl class (the class that backs SBType) in terms of a static,dynamic type pair
This is useful for those cases when the dynamic type of an ObjC variable can only be obtained in terms of an "hollow" type with no ivars
In that case, we could either go with the static type (+iVar information) or with the dynamic type (+inheritance chain)
With the new TypeImpl implementation, we try to combine these two sources of information in order to extract as much information as possible
This should improve the functionality of tools that are using the SBType API to do extensive dynamic type inspection

So when breakpoints are specified as hardware breakpoints, they might fail to be set when they are able to be resolved and should be used sparingly. This is currently hooked up for GDB remote debugging.

A long time ago we start with clang types that were created by the symbol files and there were many functions in lldb_private::ClangASTContext that helped. Later we create ClangASTType which contains a clang::ASTContext and an opauque QualType, but we didn't switch over to fully using it. There were a lot of places where we would pass around a raw clang_type_t and also pass along a clang::ASTContext separately. This left room for error.
This checkin change all type code over to use ClangASTType everywhere and I cleaned up the interfaces quite a bit. Any code that was in ClangASTContext that was type related, was moved over into ClangASTType. All code that used these types was switched over to use all of the new goodness.

PC relative loads are missing disassembly comments when disassembled in a live process.
This issue was because some sections, like __TEXT and __DATA in libobjc.A.dylib, were being moved when they were put into the dyld shared cache. This could also affect any other system that slides sections individually.
The solution is to keep track of wether the bytes we will disassemble are from an executable file (file address), or from a live process (load address). We now do the right thing based off of this input in all cases.

The attached patch fixes a problem with performing an attach from the SBTarget API on Linux (and other systems that use ProcessPOSIX).
When Process::Attach was called from SBTarget, it resulted in a call to a form of the DoAttachWithID function that wasn't implemented in ProcessPOSIX, and so it fell back to the default implementation (which just returns an error). It didn't seem necessary to use the attach_info parameter for this case, so I just implemented it as a call to the simpler version of the function.
In debugging this problem, I also found that SBTarget wasn't checking the return value from the Attach call, causing it to hang when the attach fails.

Make breakpoint setting by file and line much more efficient by only looking for inlined breakpoint locations if we are setting a breakpoint in anything but a source implementation file. Implementing this complex for a many reasons. Turns out that parsing compile units lazily had some issues with respect to how we need to do things with DWARF in .o files. So the fixes in the checkin for this makes these changes:
- Add a new setting called "target.inline-breakpoint-strategy" which can be set to "never", "always", or "headers". "never" will never try and set any inlined breakpoints (fastest). "always" always looks for inlined breakpoint locations (slowest, but most accurate). "headers", which is the default setting, will only look for inlined breakpoint locations if the breakpoint is set in what are consudered to be header files, which is realy defined as "not in an implementation source file".
- modify the breakpoint setting by file and line to check the current "target.inline-breakpoint-strategy" setting and act accordingly
- Modify compile units to be able to get their language and other info lazily. This allows us to create compile units from the debug map and not have to fill all of the details in, and then lazily discover this information as we go on debuggging. This is needed to avoid parsing all .o files when setting breakpoints in implementation only files (no inlines). Otherwise we would need to parse the .o file, the object file (mach-o in our case) and the symbol file (DWARF in the object file) just to see what the compile unit was.
- modify the "SymbolFileDWARFDebugMap" to subclass lldb_private::Module so that the virtual "GetObjectFile()" and "GetSymbolVendor()" functions can be intercepted when the .o file contenst are later lazilly needed. Prior to this fix, when we first instantiated the "SymbolFileDWARFDebugMap" class, we would also make modules, object files and symbol files for every .o file in the debug map because we needed to fix up the sections in the .o files with information that is in the executable debug map. Now we lazily do this in the DebugMapModule::GetObjectFile()
Cleaned up header includes a bit as well.

The ELF plug-in has been modified to set this for the ".tdata" and the ".tbss"

Eventually we need to have each lldb_private::Thread subclass be able to
resolve a thread specific section, but for now they will just not resolve. The
code for that should be trivual to add, but the address resolving functions
will need to be changed to take a "ExecutionContext" object instead of just

Fixed type lookups to "do the right thing". Prior to this fix, looking up a type using "foo::bar" would result in a type list that contains all types that had "bar" as a basename unless the symbol file was able to match fully qualified names (which our DWARF parser does not).
This fix will allow type matches to be made based on the basename and then have the types that don't match filtered out. Types by name can be fully qualified, or partially qualified with the new "bool exact_match" parameter to the Module::FindTypes() method.
This fixes some issue that we discovered with dynamic type resolution as well as improves the overall type lookups in LLDB.

more of the local path, platform path, associated symbol file, UUID, arch,
object name and object offset. This allows many of the calls that were
GetSharedModule to reduce the number of arguments that were used in a call
to these functions. It also allows a module to be created with a ModuleSpec
which allows many things to be specified prior to any accessors being called
on the Module class itself.
I was running into problems when adding support for "target symbol add"
where you can specify a stand alone debug info file after debugging has started
where I needed to specify the associated symbol file path and if I waited until
after construction, the wrong symbol file had already been located. By using
the ModuleSpec it allows us to construct a module with as little or as much
information as needed and not have to change the parameter list.

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

I started work on being able to add symbol files after a debug session
had started with a new "target symfile add" command and quickly ran into
problems with stale Address objects in breakpoint locations that had
lldb_private::Section pointers into modules that had been removed or
replaced. This also let to grabbing stale modules from those sections.
So I needed to thread harded the Address, Section and related objects.
To do this I modified the ModuleChild class to now require a ModuleSP
on initialization so that a weak reference can created. I also changed
all places that were handing out "Section *" to have them hand out SectionSP.
All ObjectFile, SymbolFile and SymbolVendors were inheriting from ModuleChild
so all of the find plug-in, static creation function and constructors now
require ModuleSP references instead of Module *.
Address objects now have weak references to their sections which can
safely go stale when a module gets destructed.
This checkin doesn't complete the "target symfile add" command, but it
does get us a lot clioser to being able to do such things without a high
risk of crashing or memory corruption.

user space programs. The core file support is implemented by making a process
plug-in that will dress up the threads and stack frames by using the core file
memory.
Added many default implementations for the lldb_private::Process functions so
that plug-ins like the ProcessMachCore don't need to override many many
functions only to have to return an error.
Added new virtual functions to the ObjectFile class for extracting the frozen
thread states that might be stored in object files. The default implementations
return no thread information, but any platforms that support core files that
contain frozen thread states (like mach-o) can make a module using the core
file and then extract the information. The object files can enumerate the
threads and also provide the register state for each thread. Since each object
file knows how the thread registers are stored, they are responsible for
creating a suitable register context that can be used by the core file threads.
Changed the process CreateInstace callbacks to return a shared pointer and
to also take an "const FileSpec *core_file" parameter to allow for core file
support. This will also allow for lldb_private::Process subclasses to be made
that could load crash logs. This should be possible on darwin where the crash
logs contain all of the stack frames for all of the threads, yet the crash
logs only contain the registers for the crashed thrad. It should also allow
some variables to be viewed for the thread that crashed.

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.
