artifical members (like the vtable pointer member that shows up in the DWARF).
We were adding this to each class which was making all member variables be off
by a pointer size.
Added a test case so we can track this with "test/forward".
Fixed the type name index in DWARF to include all the types after finding
some types were being omitted due to the DW_AT_specification having the
DW_AT_declaration attribute which was being read into the real type instances
when there were forward declarations in the DWARF, causing the type to be
omitted. We now check to make sure any DW_AT_declaration values are only
respected when parsing types if the attribute is from the current DIE.
After fixing the missing types, we ran into some issues with the expression
parser finding duplicate entries for __va_list_tag since they are built in
types and would result in a "duplicate __va_list_tag definition" error. We
are now just ignoring this name during lookup, but we will need to see if
we can get the name lookup function to not get called in these cases.
Fixed an issue that would cause an assertion where DW_TAG_subroutine_types
that had no children, would not properly make a clang function type of:
"void (*) (void)".
llvm-svn: 116392
function. It will inspect NAME and do the following:
- if the name contains '(' or starts with "-[" or "+[" then a full name search
will happen to match full function names with args (C++ demangled names) or
full objective C method prototypes.
- if the name contains "::" and no '(', then it is assumed to be a qualified
function name that is in a namespace or class. For "foo::bar::baz" we will
search for any functions with the basename or method name of "baz", then
filter the results to only those that contain "foo::bar::baz". This allows
setting breakpoint on C++ functions and methods without having to fully
qualify all of the types that would appear in C++ mangled names.
- if the name contains ":" (not "::"), then NAME is assumed to be an ObjC
selector.
_ otherwise, we assume just a plain function basename.
Now that "--name" is our "auto" mode, I introduced the new "--basename" option
("breakpoint set --basename NAME") to allow for function names that aren't
methods or selectors, just basenames. This can also be used to ignore C++
namespaces and class hierarchies for class methods.
Fixed clang enumeration promotion types to be correct.
llvm-svn: 116293
being chopped up correctly). The DWARF plug-in also keeps a map of the ObjC
class names to selectors for easy parsing of all class selectors when we parse
the class type.

lldb_private::RegularExpression compiles and matches with:
size_t
RegularExpression::GetErrorAsCString (char *err_str,
size_t err_str_max_len) const;
Added the ability to search a variable list for variables whose names match
a regular expression:
size_t
VariableList::AppendVariablesIfUnique (const RegularExpression& regex,
VariableList &var_list,
size_t& total_matches);
Also added the ability to append a variable to a VariableList only if it is
not already in the list:
bool
VariableList::AddVariableIfUnique (const lldb::VariableSP &var_sp);
Cleaned up the "frame variable" command:
- Removed the "-n NAME" option as this is the default way for the command to
work.
- Enable uniqued regex searches on variable names by fixing the "--regex RE"
command to work correctly. It will match all variables that match any
regular expressions and only print each variable the first time it matches.
- Fixed the option type for the "--regex" command to by eArgTypeRegularExpression
instead of eArgTypeCount
llvm-svn: 116178
Added frame relative frame selection to "frame select". You can now select
frames relative to the current frame (which defaults to zero if the current
frame hasn't yet been set for a thread):
The gdb "up" command can be done as:
(lldb) frame select -r 1
The gdb "down" command can be done as:
(lldb) frame select -r -1
Place the following in your ~/.lldbinit file for "up" and "down":
command alias up frame select -r 1
command alias down frame select -r -1
llvm-svn: 116176
as binary bytes or as an ASCII text dump.
- The output file is specified with the "--outfile FILE" option.
- The memory can be appended to an existing file using the "--append" option.
- The memory will be written as an ASCII text dump by default, or as
binary with the "--binary" option.
Added new options to memory write to allow writing all or part of
a file on disk to target memory:
- The input file is specified using the "--infile FILE" option
- The offset at which to start in the file defaults to zero, but
can be overridden using the "--offset OFFSET" option. If the
size is not specified, the remaining number of bytes in the file
will be used as the default byte size.
- The number of bytes to write defaults to the entire file byte
size, but can be changed with the "--size COUNT" option.
llvm-svn: 116172
Update the expected match string.
o lldbtest.py:
Indicate when a command fails, even if there is nothing in the error stream.
o TestHelp.py:
Add a regression test case for 'help image dump symtab'.
o CommandObjectHelp.cpp:
Some of the logic branches with successful help command results were not tagged
with a Success Status. They are fixed now. This is important for Python
interaction.
llvm-svn: 116062
Added a new SortOrder enumeration and hooked it up to the "image dump symtab"
command so we can dump symbol tables in the original order, sorted by address,
or sorted by name.
llvm-svn: 116049
if the address comes from a data section.
Fixed an issue that could occur when looking up a symbol that has a zero
byte size where no match would be returned even if there was an exact symbol
match.
Cleaned up the section dump output and added the section type into the output.

ScriptInterpreterPython class and made a simple callback function that
ScriptInterpreterPython::BreakpointCallbackFunction() now calls so we don't
include any internal API stuff into the cpp file that is generated by SWIG.
Fixed a few build warnings in debugserver.
llvm-svn: 115926
tricks to get types to resolve. I did this by correctly including the correct
files: stdint.h and all lldb-*.h files first before including the API files.
This allowed me to remove all of the hacks that were in the lldb.swig file
and it also allows all of the #defines in lldb-defines.h and enumerations
in lldb-enumerations.h to appear in the lldb.py module. This will make the
python script code a lot more readable.
Cleaned up the "process launch" command to not execute a "process continue"
command, it now just does what it should have with the internal API calls
instead of executing another command line command.
Made the lldb_private::Process set the state to launching and attaching if
WillLaunch/WillAttach return no error respectively.
llvm-svn: 115902
Temporarily commenting out the deprecated LaunchProcess() method.
SWIG is not able to handle the overloaded functions.
o dotest.py/lldbtest.py:
Add an '-w' option to insert some wait time between consecutive test cases.
o TestClassTypes.py:
Make the breakpoint_creation_by_filespec_python() test method more robust and
more descriptive by printing out a more insightful assert message.
o lldb.swig: Coaches swig to treat StateType as an int type, instead of a C++ class.
llvm-svn: 115899
Move anything that creates a new process into SBTarget. Marked some functions
as deprecated. I will remove them after our new API changes make it through
a build cycle.
llvm-svn: 115854
use the python API that is exposed through SWIG to do some cool stuff.
Also fixed synchronous debugging so that all process control APIs exposed
through the python API will now wait for the process to stop if you set
the async mode to false (see disasm.py).

bool ValueObject::GetIsConstant() const;
void ValueObject::SetIsConstant();
This will stop anything from being re-evaluated within the value object so
that constant result value objects can maintain their frozen values without
anything being updated or changed within the value object.
Made it so the ValueObjectConstResult can be constructed with an
lldb_private::Error object to allow for expression results to have errors.
Since ValueObject objects contain error objects, I changed the expression
evaluation in ClangUserExpression from
static Error
ClangUserExpression::Evaluate (ExecutionContext &exe_ctx,
const char *expr_cstr,
lldb::ValueObjectSP &result_valobj_sp);
to:
static lldb::ValueObjectSP
Evaluate (ExecutionContext &exe_ctx, const char *expr_cstr);
Even though expression parsing is borked right now (pending fixes coming from
Sean Callanan), I filled in the implementation for:
SBValue SBFrame::EvaluateExpression (const char *expr);
Modified all expression code to deal with the above changes.
llvm-svn: 115589
results. The clang opaque type for the expression result will be added to the
Target's ASTContext, and the bytes will be stored in a DataBuffer inside
the new object. The class is named: ValueObjectConstResult
Now after an expression is evaluated, we can get a ValueObjectSP back that
contains a ValueObjectConstResult object.
Relocated the value object dumping code into a static function within
the ValueObject class instead of being in the CommandObjectFrame.cpp file
which is what contained the code to dump variables ("frame variables").
