Greg Clayton 6eee5aa067 Added a "--no-lldbinit" option (-n for short (which magically matches
what gdb uses)) so we can tell our "lldb" driver program to not automatically
parse any .lldbinit files.

Greg Clayton 46747022d2 Added the ability to get error strings back from failed
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

Greg Clayton 864174e100 Added a new test case to test signals with.
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

Greg Clayton 222f5700c2 Plugged memory leak.
llvm-svn: 116175
2010-10-10 22:07:18 +00:00
Greg Clayton 6d7e77b9dc Added new options to memory read to allow saving memory to disk
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.

Johnny Chen 493b526bf7 Simplify the generator adaptor to a Python function instead of a class definition,
with the function name 'lldb_iter'.  Example:

def disassemble_instructions (insts):
    from lldbutil import lldb_iter
    for i in lldb_iter(insts, 'GetSize', 'GetInstructionAtIndex'):
        print i

        for i in Iterator(insts, 'GetSize', 'GetInstructionAtIndex'):
            print i

if the address comes from a data section. 

Fixed an issue that could occur when looking up a symbol that has a zero

match.

Cleaned up the section dump output and added the section type into the output.

Greg Clayton c6ed542c90 More SWIG cleanup. Moved the breakpoint callback function back to the
ScriptInterpreterPython class and made a simple callback function that

Greg Clayton 05faeb7135 Cleaned up the SWIG stuff so all includes happen as they should, no pulling
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.

Johnny Chen 56e6cbdaf0 Enhance the test driver with a '-f filterspec' option to specify the
testclass.testmethod to be run and with a '-g' option which instructs the test
driver to only admit the module which satisfy the filterspec condition to the
test suite.

Example:

# This only runs the test case under the array_types directory which has class
# name of 'ArrayTypesTestCase' and the test method name of 'test_with_dwarf_and_run_command'.

/Volumes/data/lldb/svn/trunk/test $ ./dotest.py -v -f 'ArrayTypesTestCase.test_with_dwarf_and_run_command' -g array_types

test_with_dwarf_and_run_command (TestArrayTypes.ArrayTypesTestCase)
Test 'frame variable var_name' on some variables with array types. ... ok

----------------------------------------------------------------------
Ran 1 test in 1.353s

OK

# And this runs the test cases under the array_types and the hello_world directories.
# If the module discovered has the 'ArrayTypesTestCase.test_with_dwarf_and_run_command'
# attribute, only the test case specified by the filterspec for the module will be run.
# If the module does not have the said attribute, e.g., the module under hello_world,
# the whole module is still admitted to the test suite.

/Volumes/data/lldb/svn/trunk/test $ ./dotest.py -v -f 'ArrayTypesTestCase.test_with_dwarf_and_run_command' array_types hello_world

llvm-svn: 115636
2010-10-05 17:34:07 +00:00
Greg Clayton b71f384455 Added the notion that a value object can be constant by adding:
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
2010-10-05 03:13:51 +00:00
Greg Clayton 0184f01936 Moved expression evaluation from CommandObjectExpression into

2010-10-05 00:08:08 +00:00
Greg Clayton 1d3afba3a3 Added a new ValueObject type that will be used to freeze dry expression
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").

2010-10-04 02:44:26 +00:00
Greg Clayton 877b59dc9c Added documentation for the new frame and thread format strings.
llvm-svn: 115488
2010-10-04 02:33:45 +00:00
Greg Clayton 0603aa9dc8 There are now to new "settings set" variables that live in each debugger
instance:

settings set frame-format <string>
settings set thread-format <string>

This allows users to control the information that is seen when dumping
threads and frames. The default values are set such that they do what they
used to do prior to changing over the the user defined formats.

This allows users with terminals that can display color to make different
items different colors using the escape control codes. A few alias examples
that will colorize your thread and frame prompts are:

settings set frame-format 'frame #${frame.index}: \033[0;33m${frame.pc}\033[0m{ \033[1;4;36m${module.file.basename}\033[0;36m ${function.name}{${function.pc-offset}}\033[0m}{ \033[0;35mat \033[1;35m${line.file.basename}:${line.number}}\033[0m\n'

settings set thread-format 'thread #${thread.index}: \033[1;33mtid\033[0;33m = ${thread.id}\033[0m{, \033[0;33m${frame.pc}\033[0m}{ \033[1;4;36m${module.file.basename}\033[0;36m ${function.name}{${function.pc-offset}}\033[0m}{, \033[1;35mstop reason\033[0;35m = ${thread.stop-reason}\033[0m}{, \033[1;36mname = \033[0;36m${thread.name}\033[0m}{, \033[1;32mqueue = \033[0;32m${thread.queue}}\033[0m\n'

A quick web search for "colorize terminal output" should allow you to see what
you can do to make your output look like you want it.

The "settings set" commands above can of course be added to your ~/.lldbinit
file for permanent use.

Changed the pure virtual 
    void ExecutionContextScope::Calculate (ExecutionContext&);
To:
    void ExecutionContextScope::CalculateExecutionContext (ExecutionContext&);
    
I did this because this is a class that anything in the execution context
heirarchy inherits from and "target->Calculate (exe_ctx)" didn't always tell
you what it was really trying to do unless you look at the parameter.

Johnny Chen da88434b39 o Added a new feature to the test framework to skip long running tests conditionally.
To not skip long running tests, pass '-l' to the test driver (dotest.py).

  An example:

    @unittest2.skipIf(TestBase.skipLongRunningTest(), "Skip this long running test")
    def test_foundation_disasm(self):
        ...

o Added a long running disassemble test to the foundation directory, which iterates
  the code symbols from Foundation.framework and kicks off a disassemble command for
  for the named function symbol.  Found a crasher: rdar://problem/8504895.

o Plus added/updated some comments for the TestBase class.

Johnny Chen f14331f5c3 Only skip the test cases which are currently crashing, instead of the whole class.

llvm-svn: 115320
2010-10-01 18:08:29 +00:00
Caroline Tice e139cf2320 Add infrastructure for standardizing arguments for commands and
command options; makes it easier to ensure that the same type of
argument will have the same name everywhere, hooks up help for command
arguments, so that users can ask for help when they are confused about
what an argument should be; puts in the beginnings of the ability to
do tab-completion for certain types of arguments, allows automatic
syntax help generation for commands with arguments, and adds command
arguments into command options help correctly.

Currently only the breakpoint-id and breakpoint-id-range arguments, in
the breakpoint commands, have been hooked up to use the new mechanism.
The next steps will be to fix the command options arguments to use
this mechanism, and to fix the rest of the regular command arguments
to use this mechanism.  Most of the help text is currently missing or
dummy text; this will need to be filled in, and the existing argument
help text will need to be cleaned up a bit (it was thrown in quickly,
mostly for testing purposes).

Help command now works for all argument types, although the help may not
be very helpful yet.

Those commands that take "raw" command strings now indicate it in their
help text.

Greg Clayton 1437224a7c Updated LLVM to: --revision '{2010-09-28T19:30}'
This gets us the new clang::CXXRecordDecl improvments in clang so that when we
add fields, methods and other things to the clang::CXXRecordDecl, the correct
bits are automatically set by clang::CXXRecordDecl itself instead of having 
SEMA and our lldb_private::ClangASTContext functions that create types for
DWARF do it all manually. This allows the clang::ASTContext deep copying of
types to work correctly and it means that the expression parser can now 
evaluate expressions in the context of a class method correctly. Previously
when a class was copied from the DWARF generated ASTContext over into the
expression ASTContext, we were losing CXXRecordDecl bits in the conversion
which caused all classes to think they were at offset zero because the the 
bools for empty, POD, and others would end up being incorrect.

llvm-svn: 115023
2010-09-29 03:44:17 +00:00
Greg Clayton 6d01ad92c7 Fixed an LLVM/Clang assertion that would happen for C++ and ObjC methods if the DWARF doesn't specify the accessibility for the method. Currently gcc 4.2 and clang++ do not set the accessibility correctly on methods. We currently shouldn't default to private since public methods don't have the accessibility specified.
Bottom line: we currently default to public for both C++ and ObjC if the accessibility isn't set.

llvm-svn: 115016
2010-09-29 01:57:37 +00:00
Greg Clayton 1be10fca5f Fixed the forward declaration issue that was present in the DWARF parser after
adding methods to C++ and objective C classes. In order to make methods, we
need the function prototype which means we need the arguments. Parsing these
could cause a circular reference that caused an  assertion.

Added a new typedef for the clang opaque types which are just void pointers:
lldb::clang_type_t. This appears in lldb-types.h.

This was fixed by enabling struct, union, class, and enum types to only get
a forward declaration when we make the clang opaque qual type for these
types. When they need to actually be resolved, lldb_private::Type will call
a new function in the SymbolFile protocol to resolve a clang type when it is
not fully defined (clang::TagDecl::getDefinition() returns NULL). This allows
us to be a lot more lazy when parsing clang types and keeps down the amount
of data that gets parsed into the ASTContext for each module. 

Getting the clang type from a "lldb_private::Type" object now takes a boolean
that indicates if a forward declaration is ok:

    clang_type_t lldb_private::Type::GetClangType (bool forward_decl_is_ok);
    
So function prototypes that define parameters that are "const T&" can now just
parse the forward declaration for type 'T' and we avoid circular references in
the type system.

Right now, they don't employ the self.expect() facility to compare against the

Johnny Chen 6316021bae Added "float" and "double" to types/TestBasicTypes.py. Abstracted the generic
type tester method into its own abstarct base class 'AbstractBase'.  And
added TestIntegerTypes.py and TestFloatTypes.py.

Added an option "-p reg-exp-pattern" to the test driver to specify a regular
expression pattern to match against eligible filenames as our test cases.

An example: 

/Volumes/data/lldb/svn/trunk/test $ ./dotest.py -v -p "TestFloat.*" types

Johnny Chen e1030cd883 Added "long long" and "unsigned long long" to the TestBasicTypes.py.
Added a special "clean" target to the types/Makefile to clean up all the *.o/.d
files.

The generic_type_tester() method is modified to take a set of atoms, instead of
type string as a required parameter, for example:

o unsigned int => set(['unsigned', 'int'])
o unsigned long long => set(['unsigned', 'long long'])
o long long => set(['long long'])

Greg Clayton 0fffff5816 Added the ability to create an objective C method for an objective C
interface in ClangASTContext. Also added two bool returning functions that
indicated if an opaque clang qual type is a CXX class type, and if it is an
ObjC class type.

Objective C classes now will get their methods added lazily as they are
encountered. The reason for this is currently, unlike C++, the 
DW_TAG_structure_type and owns the ivars, doesn't not also contain the
member functions. This means when we parse the objective C class interface
we either need to find all functions whose names start with "+[CLASS_NAME"
or "-[CLASS_NAME" and add them all to the class, or when we parse each objective
C function, we slowly add it to the class interface definition. Since objective
C's class doesn't change internal bits according to whether it has certain types
of member functions (like C++ does if it has virtual functions, or if it has
user ctors/dtors), I currently chose to lazily populate the class when each
functions is parsed. Another issue we run into with ObjC method declarations
is the "self" and "_cmd" implicit args are not marked as artificial in the
DWARF (DW_AT_artifical), so we currently have to look for the parameters by
name if we are trying to omit artificial function args if the language of the
compile unit is ObjC or ObjC++.

llvm-svn: 114722
2010-09-24 05:15:53 +00:00
Johnny Chen b052f6c595 Added a generic_type_tester() to the TestBasicTypes class to be used for
testing various combinations of displaying variales of basic types.

The generic_type_tester() works by first capturing the golden output produced
by the printf stmts of ./a.out, creating a list of (var, value) pairs, and then
running the a.out to a stop point, and comparing the 'frame variable var' output
against the list of (var, value) pairs.

Modified int_type() and added long_type() to use generic_type_tester().

Also modified TestBase.expect() such that substring matching also return ok if
the substring starts at the 0-th position.

right after each data type test is run.  The test case can pass a dictionary
object when registering the test case cleanup.

There is currently only int_type test in the repository.

Johnny Chen ea88e94318 Added a more complex test case of breakpoint commands, which executes a sequence
of 'breakpoint command add/list/remove' commands to set breakpoint callbacks,
list them, and then remove one.

Modified the lldbtest.TestBase.expect() method to add two additional keyword
arguments:

o matching (default to True), which, if set to False, reverses the semantics of
  'expect' to 'expect not'

o patterns (default to None), which specifies a list of regexp patterns to match
  against the output from running the command

TestBreakpointCommand.py uses the matching=False and the patterns=[...] expect()
API.

Sean Callanan fc55f5d1b0 Removed the hacky "#define this ___clang_this" handler
for C++ classes.  Replaced it with a less hacky approach:

 - If an expression is defined in the context of a
   method of class A, then that expression is wrapped as
   ___clang_class::___clang_expr(void*) { ... }
   instead of ___clang_expr(void*) { ... }.

 - ___clang_class is resolved as the type of the target
   of the "this" pointer in the method the expression
   is defined in.

 - When reporting the type of ___clang_class, a method
   with the signature ___clang_expr(void*) is added to
   that class, so that Clang doesn't complain about a
   method being defined without a corresponding
   declaration.

 - Whenever the expression gets called, "this" gets
   looked up, type-checked, and then passed in as the
   first argument.

This required the following changes:

 - The ABIs were changed to support passing of the "this"
   pointer as part of trivial calls.

 - ThreadPlanCallFunction and ClangFunction were changed
   to support passing of an optional "this" pointer.

 - ClangUserExpression was extended to perform the
   wrapping described above.

 - ClangASTSource was changed to revert the changes
   required by the hack.

 - ClangExpressionParser, IRForTarget, and
   ClangExpressionDeclMap were changed to handle
   different manglings of ___clang_expr flexibly.  This
   meant no longer searching for a function called
   ___clang_expr, but rather looking for a function whose
   name *contains* ___clang_expr.

 - ClangExpressionParser and ClangExpressionDeclMap now
   remember whether "this" is required, and know how to
   look it up as necessary.

A few inheritance bugs remain, and I'm trying to resolve
these.  But it is now possible to use "this" as well as
refer implicitly to member variables, when in the proper
context.
