map that tracks all live Module classes. We must leak our mutex for our
collection class as it might be destroyed in an order we can't control.

where we changed the CommandObjectSettingsSet object impl to require raw command string.
Do the same for CommandObjectSettingsAppend/InsertBefore/InsertAfter classes and
add test cases for basic functionalities as well as for variable name completion.
llvm-svn: 148719
where we changed the CommandObjectSettingsSet object impl to require raw command string.
Do the same for CommandObjectSettingsReplace class and add two test cases; one for
the "settings replace" command and the other to ensure that completion for variable
name still works.
llvm-svn: 148615
Fix a bug where "settings set -r th" wouldn't complete.
o UserSettingsController.cpp:
Fix a bug where "settings set target.process." wouldn't complete.
o test/functionalities/completion:
Add various completion test cases related to 'settings set' command.
llvm-svn: 148596
http://llvm.org/viewvc/llvm-project?rev=148491&view=rev check in broke the argument completion
for "settings set th", followed by TAB. Provide a way for commands who want raw commands to
hook into the completion mechanism.
llvm-svn: 148500
Fixed an issue where backtick char is not properly honored when setting the frame-format variable, like the following:
(lldb) settings set frame-format frame #${frame.index}: ${frame.pc}{ ${module.file.basename}{`${function.name-with-args}${function.pc-offset}}}{ at ${line.file.basename}:${line.number}}\n
(lldb) settings show frame-format
frame-format (string) = "frame #${frame.index}: ${frame.pc}{ `${module.file.basename}{${function.name-with-args}${function.pc-offset}}}{` at ${line.file.basename}:${line.number}}\n"
(lldb)
o CommandObjectSettings.h/.cpp:
Modify the command object impl to require raw command string instead of parsed command string,
which also fixes an outstanding issue that customizing the prompt with trailing spaces doesn't
work.
o Args.cpp:
During CommandInterpreter::HandleCommand(), there is a PreprocessCommand phase which already
strips/processes pairs of backticks as an expression eval step. There's no need to treat
a backtick as starting a quote.
o TestAbbreviations.py and change_prompt.lldb:
Fixed incorrect test case/logic.
o TestSettings.py:
Remove expectedFailure decorator.
llvm-svn: 148491
parser has hitherto been an implementation waiting
for a use. I have now tied the '-o' option for
the expression command -- which indicates that the
result is an Objective-C object and needs to be
printed -- to the ExpressionParser, which
communicates the desired type to Clang.
Now, if the result of an expression is determined
by an Objective-C method call for which there is
no type information, that result is implicitly
cast to id if and only if the -o option is passed
to the expression command. (Otherwise if there
is no explicit cast Clang will issue an error.
This behavior is identical to what happened before
r146756.)
Also added a testcase for -o enabled and disabled.
llvm-svn: 147099
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
take a SymbolFile reference and a lldb::user_id_t and be used in objects
which represent things in debug symbols that have types where we don't need
to know the true type yet, such as in lldb_private::Variable objects. This
allows us to defer resolving the type until something is used. More specifically
this allows us to get 1000 local variables from the current function, and if
the user types "frame variable argc", we end up _only_ resolving the type for
"argc" and not for the 999 other local variables. We can expand the use of this
as needed in the future.
Modified the DWARFMappedHash class to be able to read the HashData that has
more than just the DIE offset. It currently will read the atoms in the header
definition and read the data correctly. Currently only the DIE offset and
type flags are supported. This is needed for adding type flags to the
.apple_types hash accelerator tables.
Fixed a assertion crash that would happen if we have a variable that had a
DW_AT_const_value instead of a location where "location.LocationContains_DW_OP_addr()"
would end up asserting when it tried to parse the variable location as a
DWARF opcode list.
Decreased the amount of memory that LLDB would use when evaluating an expression
by 3x - 4x for clang. There was a place in the namespace lookup code that was
parsing all namespaces with a certain name in a DWARF file instead of stopping
when it found the first match. This was causing all of the compile units with
a matching namespace to get parsed into memory and causing unnecessary memory
bloat.
Improved "Target::EvaluateExpression(...)" to not try and find a variable
when the expression contains characters that would certainly cause an expression
to need to be evaluated by the debugger.
llvm-svn: 146130
will allow us to represent a process/thread ID using a pointer for the OS
plug-ins where they might want to represent the process or thread ID using
the address of the process or thread structure.
llvm-svn: 145644
Fixed an issue where if we are debugging on a remote platform and set a
platform path for our executable, it was not being honored by the new
launch functions that used the ProcessLaunchInfo.
llvm-svn: 145371
to launch a process for debugging. Since this isn't supported on all platforms,
we need to do what we used to do if this isn't supported. I added:
bool
Platform::CanDebugProcess ();
This will get checked before trying to launch a process for debugging and then
fall back to launching the process through the current host debugger. This
should solve the issue for linux and keep the platform code clean.
Centralized logging code for logging errors, warnings and logs when reporting
things for modules or symbol files. Both lldb_private::Module and
lldb_private::SymbolFile now have the following member functions:
void
LogMessage (Log *log, const char *format, ...);
void
ReportWarning (const char *format, ...);
void
ReportError (const char *format, ...);
These will all output the module name and object (if any) such as:
"error: lldb.so ...."
"warning: my_archive.a(foo.o) ...."
This will keep the output consistent and stop a lot of logging calls from
having to try and output all of the information that uniquely identifies
a module or symbol file. Many places in the code were grabbing the path to the
object file manually and if the module represented a .o file in an archive, we
would see log messages like:
error: foo.a - some error happened
llvm-svn: 145219
Fixed an issue with the options for memory read where --count couldn't be used
with the --binary option when writing data to a file.
Also removed the GDB format option from the --binary version of memory read.
llvm-svn: 145067
the thread specific data and were destroying the thread specfic data more
than once.
Also added the ability to ask a lldb::StateType if it is stopped with an
additional paramter of "must_exist" which means that the state must be a
stopped state for a process that still exists. This means that eStateExited
and eStateUnloaded will no longer return true if "must_exist" is set to true.
llvm-svn: 144875
info for us to attach by pid, or by name and will also allow us to eventually
do a lot more powerful attaches. If you look at the options for the "platform
process list" command, there are many options which we should be able to
specify. This will allow us to do things like "attach to a process named 'tcsh'
that has a parent process ID of 123", or "attach to a process named 'x' which
has an effective user ID of 345".
I finished up the --shell implementation so that it can be used without the
--tty option in "process launch". The "--shell" option now can take an
optional argument which is the path to the shell to use (or a partial name
like "sh" which we will find using the current PATH environment variable).
Modified the Process::Attach to use the new ProcessAttachInfo as the sole
argument and centralized a lot of code that was in the "process attach"
Execute function so that everyone can take advantage of the powerful new
attach functionality.
llvm-svn: 144615
This is the actual fix for the above radar where global variables that weren't
initialized were not being shown correctly when leaving the DWARF in the .o
files. Global variables that aren't intialized have symbols in the .o files
that specify they are undefined and external to the .o file, yet document the
size of the variable. This allows the compiler to emit a single copy, but makes
it harder for our DWARF in .o files with the executable having a debug map
because the symbol for the global in the .o file doesn't exist in a section
that we can assign a fixed up linked address to, and also the DWARF contains
an invalid address in the "DW_OP_addr" location (always zero). This means that
the DWARF is incorrect and actually maps all such global varaibles to the
first file address in the .o file which is usually the first function. So we
can fix this in either of two ways: make a new fake section in the .o file
so that we have a file address in the .o file that we can relink, or fix the
the variable as it is created in the .o file DWARF parser and actually give it
the file address from the executable. Each variable contains a
SymbolContextScope, or a single pointer that helps us to recreate where the
variables came from (which module, file, function, etc). This context helps
us to resolve any file addresses that might be in the location description of
the variable by pointing us to which file the file address comes from, so we
can just replace the SymbolContextScope and also fix up the location, which we
would have had to do for the other case as well, and update the file address.
Now globals display correctly.
The above changes made it possible to determine if a variable is a global
or static variable when parsing DWARF. The DWARF emits a DW_TAG_variable tag
for each variable (local, global, or static), yet DWARF provides no way for
us to classify these variables into these categories. We can now detect when
a variable has a simple address expressions as its location and this will help
us classify these correctly.
While making the above changes I also noticed that we had two symbol types:
eSymbolTypeExtern and eSymbolTypeUndefined which mean essentially the same
thing: the symbol is not defined in the current object file. Symbol objects
also have a bit that specifies if a symbol is externally visible, so I got
rid of the eSymbolTypeExtern symbol type and moved all code locations that
used it to use the eSymbolTypeUndefined type.
llvm-svn: 144489
the --tty option. So you can now get shell expansion and file redirection:
(lldb) process launch --tty --shell -- *.jpg < in.txt > out.txt
Again, the "--tty" is mandatory for now until we hook this up to other
functions. The shell is also currently hard coded to "/bin/bash" and not the
"SHELL" variable. "/bin/tcsh" was causing problems which I need to dig into.
llvm-svn: 144443
the argument description in the command name could cause a command
alias to crash, e.g.
command alias zzz target stop-hook delete 1
because the "name" is used to re-fetch the exact CommandObject when
adding the final arg.

be in the target. All of the environment, args, stdin/out/err files, etc have
all been moved. Also re-enabled the ability to launch a process in a separate
terminal on MacOSX.
llvm-svn: 144061
a) adds a new --synchronicity (-s) setting for "command script add" that allows the user to decide if scripted commands should run synchronously or asynchronously (which can make a difference in how events are handled)
b) clears up several error messages
c) adds a new --allow-reload (-r) setting for "command script import" that allows the user to reload a module even if it has already been imported before
d) allows filename completion for "command script import" (much like what happens for "target create")
e) prevents "command script add" from replacing built-in commands with scripted commands
f) changes AddUserCommand() to take an std::string instead of a const char* (for performance reasons)
plus, it fixes an issue in "type summary add" command handling which caused several test suite errors
llvm-svn: 144035
- If you download and build the sources in the Xcode project, x86_64 builds
by default using the "llvm.zip" checkpointed LLVM.
- If you delete the "lldb/llvm.zip" and the "lldb/llvm" folder, and build the
Xcode project will download the right LLVM sources and build them from
scratch
- If you have a "lldb/llvm" folder already that contains a "lldb/llvm/lib"
directory, we will use the sources you have placed in the LLDB directory.
Python can now be disabled for platforms that don't support it.
Changed the way the libllvmclang.a files get used. They now all get built into
arch specific directories and never get merged into universal binaries as this
was causing issues where you would have to go and delete the file if you wanted
to build an extra architecture slice.
llvm-svn: 143678
on internal only (public API hasn't changed) to simplify the paramter list
to the launch calls down into just one argument. Also all of the argument,
envronment and stdio things are now handled in a much more centralized fashion.
llvm-svn: 143656
in the same hashed format as the ".apple_names", but they map objective C
class names to all of the methods and class functions. We need to do this
because in the DWARF the methods for Objective C are never contained in the
class definition, they are scattered about at the translation unit level and
they don't even have attributes that say the are contained within the class
itself.
Added 3 new formats which can be used to display data:
eFormatAddressInfo
eFormatHexFloat
eFormatInstruction
eFormatAddressInfo describes an address such as function+offset and file+line,
or symbol + offset, or constant data (c string, 2, 4, 8, or 16 byte constants).
The format character for this is "A", the long format is "address".
eFormatHexFloat will print out the hex float format that compilers tend to use.
The format character for this is "X", the long format is "hex float".
eFormatInstruction will print out disassembly with bytes and it will use the
current target's architecture. The format character for this is "i" (which
used to be being used for the integer format, but the integer format also has
"d", so we gave the "i" format to disassembly), the long format is
"instruction".
Mate the lldb::FormatterChoiceCriterion enumeration private as it should have
been from the start. It is very specialized and doesn't belong in the public
API.
llvm-svn: 143114
properly marked as valid.
Also modified the "memory read" command to be able to intelligently repeat
subsequent memory requests, so now you can do:
(lldb) memory read --format hex --count 32 0x1000
Then hit enter to keep viewing the memory that follows the last valid request.
llvm-svn: 143015
lldb_private::Error objects the rules are:
- short strings that don't start with a capitol letter unless the name is a
class or anything else that is always capitolized
- no trailing newline character
- should be one line if possible
Implemented a first pass at adding "--gdb-format" support to anything that
accepts format with optional size/count.
llvm-svn: 142999
OptionGroupFormat. Updated OptionGroupFormat to be able to also use the
"--size" and "--count" options. Commands that use a OptionGroupFormat instance
can choose which of the options they want by initializing OptionGroupFormat
accordingly. Clients can either get only the "--format", "--format" + "--size",
or "--format" + "--size" + "--count". This is in preparation for upcoming
chnages where there are alternate ways (GDB format specification) to set a
format.
llvm-svn: 142911
process IDs, and thread IDs, but was mainly needed for for the UserID's for
Types so that DWARF with debug map can work flawlessly. With DWARF in .o files
the type ID was the DIE offset in the DWARF for the .o file which is not
unique across all .o files, so now the SymbolFileDWARFDebugMap class will
make the .o file index part (the high 32 bits) of the unique type identifier
so it can uniquely identify the types.
llvm-svn: 142534
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.
llvm-svn: 142227
a watchpoint for either the variable encapsulated by SBValue (Watch) or the pointee
encapsulated by SBValue (WatchPointee).
Removed SBFrame::WatchValue() and SBFrame::WatchLocation() API as a result of that.
Modified the watchpoint related test suite to reflect the change.
Plus replacing WatchpointLocation with Watchpoint throughout the code base.
There are still cleanups to be dome. This patch passes the whole test suite.
Check it in so that we aggressively catch regressions.
llvm-svn: 141925
Fixed up DWARFDebugAranges to use the new range classes.
Fixed the enumeration parsing to take a lldb_private::Error to avoid a lot of duplicated code. Now when an invalid enumeration is supplied, an error will be returned and that error will contain a list of the valid enumeration values.
llvm-svn: 141382
symbol context that represents an inlined function. This function has been
renamed internally to:
bool
SymbolContext::GetParentOfInlinedScope (const Address &curr_frame_pc,
SymbolContext &next_frame_sc,
Address &next_frame_pc) const;
And externally to:
SBSymbolContext
SBSymbolContext::GetParentOfInlinedScope (const SBAddress &curr_frame_pc,
SBAddress &parent_frame_addr) const;
The correct blocks are now correctly calculated.
Switched the stack backtracing engine (in StackFrameList) and the address
context printing over to using the internal SymbolContext::GetParentOfInlinedScope(...)
so all inlined callstacks will match exactly.
llvm-svn: 140910
if no frame is specified. This is useful to get the source context lines re-displayed
when you need a reminder of where you are in the source currently.
llvm-svn: 140819
iterate on the available watchpoint locations and to perform watchpoint manipulations.
I still need to export the SBWatchpointLocation class as well as the added watchpoint
manipulation methods to the Python interface. And write test cases for them.
llvm-svn: 140575
- New SBSection objects that are object file sections which can be accessed
through the SBModule classes. You can get the number of sections, get a
section at index, and find a section by name.
- SBSections can contain subsections (first find "__TEXT" on darwin, then
us the resulting SBSection to find "__text" sub section).
- Set load addresses for a SBSection in the SBTarget interface
- Set the load addresses of all SBSection in a SBModule in the SBTarget interface
- Add a new module the an existing target in the SBTarget interface
- Get a SBSection from a SBAddress object
This should get us a lot closer to being able to symbolicate using LLDB through
the public API.
llvm-svn: 140437
return before we try to dereference the target later in the function.
Currently,
% lldb -x
(lldb) target stop-hook list
crashes because of this.
llvm-svn: 140417
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
Add eArgTypeWatchpointID and eArgTypeWatchpointIDRange to the CommandArgumentType enums and
modify the signature of CommandObject::AddIDsArgumentData() from:
AddIDsArgumentData(CommandArgumentEntry &arg)
to:
AddIDsArgumentData(CommandArgumentEntry &arg, CommandArgumentType ID, CommandArgumentType IDRange)
to accommodate.
llvm-svn: 140346
shared pointers.
Changed the ExecutionContext over to use shared pointers for
the target, process, thread and frame since these objects can
easily go away at any time and any object that was holding onto
an ExecutionContext was running the risk of using a bad object.
Now that the shared pointers for target, process, thread and
frame are just a single pointer (they all use the instrusive
shared pointers) the execution context is much safer and still
the same size.
Made the shared pointers in the the ExecutionContext class protected
and made accessors for all of the various ways to get at the pointers,
references, and shared pointers.
llvm-svn: 140298
Fix the RegularExpression class so it has a real copy constructor.
Fix the breakpoint setting with multiple shared libraries so it makes
one breakpoint not one per shared library.
Add SBFileSpecList, to be used to expose the above to the SB interface (not done yet.)
llvm-svn: 140225
to the command argument entry. Add a static helper function:
CommandObject::AddIDsArgumentData(CommandArgumentEntry &arg)
to be used from CommandObjectBreakpoint.cpp. The helper function could also be useful
for commands in the future to manipulate watchpoints.
llvm-svn: 140221
stdarg formats to use __attribute__ format so the compiler can flag
incorrect uses. Fix all incorrect uses. Most of these are innocuous,
a few were resulting in crashes.
llvm-svn: 140185
__attribute__ format so the compiler knows that this method takes
printf style formatter arguments and checks that it's being used
correctly. Fix a couple dozen incorrect SetErrorStringWithFormat()
calls throughout the sources.
llvm-svn: 140115
ModuleSP
Module::GetSP();
Since we are now using intrusive ref counts, we can easily turn any
pointer to a module into a shared pointer just by assigning it.
llvm-svn: 139984
We had some cases where getting the shared pointer for a module from
the global module list was causing a performance issue when debugging
with DWARF in .o files. Now that the module uses intrusive ref counts,
we can easily convert any pointer to a shared pointer.
llvm-svn: 139983
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.
llvm-svn: 139946
to execute expressions even in the absence of a process.
This allows expressions to run in situations where the
target cannot run -- e.g., to perform calculations based
on type information, or to inspect a binary's static
data.
This modification touches the following files:
lldb-private-enumerations.h
Introduce a new enum specifying the policy for
processing an expression. Some expressions should
always be JITted, for example if they are functions
that will be used over and over again. Some
expressions should always be interpreted, for
example if the target is unsafe to run. For most,
it is acceptable to JIT them, but interpretation
is preferable when possible.
Target.[h,cpp]
Have EvaluateExpression now accept the new enum.
ClangExpressionDeclMap.[cpp,h]
Add support for the IR interpreter and also make
the ClangExpressionDeclMap more robust in the
absence of a process.
ClangFunction.[cpp,h]
Add support for the new enum.
IRInterpreter.[cpp,h]
New implementation.
ClangUserExpression.[cpp,h]
Add support for the new enum, and for running
expressions in the absence of a process.
ClangExpression.h
Remove references to the old DWARF-based method
of evaluating expressions, because it has been
superseded for now.
ClangUtilityFunction.[cpp,h]
Add support for the new enum.
ClangExpressionParser.[cpp,h]
Add support for the new enum, remove references
to DWARF, and add support for checking whether
the expression could be evaluated statically.
IRForTarget.[h,cpp]
Add support for the new enum, and add utility
functions to support the interpreter.
IRToDWARF.cpp
Removed
CommandObjectExpression.cpp
Remove references to the obsolete -i option.
Process.cpp
Modify calls to ClangUserExpression::Evaluate
to pass the correct enum (for dlopen/dlclose)
SBValue.cpp
Add support for the new enum.
SBFrame.cpp
Add support for he new enum.
BreakpointOptions.cpp
Add support for the new enum.
llvm-svn: 139772
o Rename from OptionGroupWatchpoint::WatchMode to OptionGroupWatchpoint::WatchType,
and CommandArgumentType::eArgTypeWatchMode to CommandArgumentType::eArgTypeWatchType.
Update the sources to reflect the change.
o Add a CreateWatchpointLocation() method to Target class, which is currently not implmeneted
(returns an empty WatchpointLocationSP object). Add logic to CommandObjectFrame::Execute()
to exercise the added API for creating a watchpoint location.
llvm-svn: 139560
to effect an early error return.
Plus add logic to 'frame variable' command object to check that when watchpoint option is on,
only one variable with exact name (no regex) is specified as the sole command arg.
llvm-svn: 139524
--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.
llvm-svn: 139323
Reduced the amount of memory required to avoid loops in DumpPrintableRepresentation() from 32 bits down to 1 bit
- Additionally, disallowed creating summary strings of the form ${var%S} which did nothing but cause endless loops by definition
llvm-svn: 139201
- 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
(in addition to the previous error message if the value could not be
parsed as a numbe). These both generate reasonable errors now -
reg write rip 0x500000000000000000000a
reg write rip 0x5jjjj
llvm-svn: 138543
expression parser. You can use a persistent
type like this:
(lldb) expr struct $foo { int a; int b; };
(lldb) struct $foo i; i.a = 2; i.b = 3; i
($foo) $0 = {
(int) a = 2
(int) b = 3
}
typedefs work similarly.
This patch affects the following files:
test/expression_command/persistent_types/*
A test case for persistent types,
in particular structs and typedefs.
ClangForward.h
Added TypeDecl, needed to declare some
functions in ASTResultSynthesizer.h
ClangPersistentVariables.[h,cpp]
Added a list of persistent types to the
persistent variable store.
ASTResultSynthesizer.[h,cpp]
Made the AST result synthesizer iterate
across TypeDecls in the expression, and
record any persistent types found. Also
made a minor documentation fix.
ClangUserExpression.[h,cpp]
Extended the user expression class to
keep the state needed to report the
persistent variable store for the target
to the AST result synthesizers.
Also introduced a new error code for
expressions that executed normally but
did not return a result.
CommandObjectExpression.cpp
Improved output for expressions (like
declarations of new persistent types) that
don't return a result. This is no longer
treated as an error.
