Johnny Chen b62a3be1a2 Add an accompanying option to the 'frame variable -w' command to, instead of watching the variable,
watch the location pointed to by the variable.  An example,

(lldb) frame variable -w write -x 1 -g g_char_ptr
(char *) g_char_ptr = 0x0000000100100860 ""...
Watchpoint created: WatchpointLocation 1: addr = 0x100100860 size = 1 state = enabled type = w
    declare @ '/Volumes/data/lldb/svn/trunk/test/functionalities/watchpoint/hello_watchlocation/main.cpp:21'

Johnny Chen c44e20cec0 Migrate the in_range(symbol, section) and symbol_iter(module, section) utility functions
from lldbutil.py to the lldb.py proper.  The in_range() function becomes a function in
the lldb module.  And the symbol_iter() function becomes a method within the SBModule
called symbol_in_section_iter().  Example:

        # Iterates the text section and prints each symbols within each sub-section.
        for subsec in text_sec:
            print INDENT + repr(subsec)
            for sym in exe_module.symbol_in_section_iter(subsec):
                print INDENT2 + repr(sym)
                print INDENT2 + 'symbol type: %s' % symbol_type_to_str(sym.GetType())

might produce this following output:

Greg Clayton 6c7f56192f Fixed an issue where a lexical block or inlined function might have bad debug
information generated for it. Say we have a concrete function "foo" which
has inlined function "a" which calls another inlined function "b":

    foo
1   {
2       {
            a ()
3           {
                b ()
4               {
                
                }
            }
        }
    }
    
Sometimes we see the compiler generate an address range in the DWARF for "foo"
(block 1 above) as say [0x1000-0x1100). Then the range for "a" is something
like [0x1050-0x1060) (note that it is correctly scoped within the "foo" 
address range). And then we get "b" which is a child of "a", yet the debug
info says it has a range of [0x1060-0x1080) (not contained within "a"). We now
detect this issue when making our blocks and add an extra range to "a".

Also added a new "lldb" logging category named "symbol" where we can find out
about symbol file errors and warnings.

Johnny Chen a9b68f4dd6 Modify the delegation chain from MachThreadList -> MachThread -> DNBArchProtocol so that when
the watchpoint state is changed, not only does the change propagate to all the thread instances,
it also updates a global debug state, if chosen by the DNBArchProtocol derivative.

Once implemented, the DNBArchProtocol derivative, also makes sure that when new thread comes along,
it tries to inherit from the global debug state, if it is valid.

Modify TestWatchpointMultipleThreads.py to test this functionality.

Greg Clayton 624784a987 Free up some space in lldb_private::Block by not requiring a sibling pointer.
The old way of storing blocks used to use the sibling pointer, but now all
blocks contain a collection of shared pointers to blocks so this isn't required
anymore and a parent can be asked to find the sibling block for a child block.

and then symbolicate all frames and expand any frames that had inlined
functions in them to show all frames back to the concrete function. It
will also disassemble around the crash site.

Greg Clayton 8f7180b11e Added more functionality to the public API to allow for better
symbolication. Also improved the SBInstruction API to allow
access to the instruction opcode name, mnemonics, comment and
instruction data.

Added the ability to edit SBLineEntry objects (change the file,
line and column), and also allow SBSymbolContext objects to be
modified (set module, comp unit, function, block, line entry
or symbol). 

The SymbolContext and SBSymbolContext can now generate inlined
call stack infomration for symbolication much easier using the
SymbolContext::GetParentInlinedFrameInfo(...) and 
SBSymbolContext::GetParentInlinedFrameInfo(...) methods.

Added the ability to dump data with address annotations when
call SBData::GetDescription().

Hooked up the SBSection to the __repr__ so you can print section
objects from within python.

Improved the dumping of symbols from python.

Fixed the .i interface references which were set to "Relative to this Group"

Greg Clayton cac9c5f971 Added to the public API to allow symbolication:
- 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
2011-09-24 00:52:29 +00:00
Johnny Chen 6027c94d2f Add an SB API SBFrame::WatchValue() and exported to the Python interface to
set a watchpoint Pythonically.  If the find-and-watch-a-variable operation
fails, an invalid SBValue is returned, instead.

Example Python usage:

        value = frame0.WatchValue('global',
                                  lldb.eValueTypeVariableGlobal,
                                  lldb.LLDB_WATCH_TYPE_READ|lldb.LLDB_WATCH_TYPE_WRITE)

Greg Clayton c14ee32db5 Converted the lldb_private::Process over to use the intrusive
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.

Greg Clayton 762f7135e2 Don't put modules for .o files into the global shared module list. We
used to do this because we needed to find the shared pointer for a .o
file when the .o file's module was needed in a SymbolContext since the
module in a symbol context was a shared pointer. Now that we are using
intrusive pointers we don't have this limitation anymore since any
instrusive shared pointer can be made from a pointer to an object
all on its own.

Also switched over to having the Module and SymbolVendor use shared 
pointers to their object files as had a leak on MacOSX when the 
SymbolVendor's object file wasn't the same as the Module's (debug info
in a stand along file (dSYM file)). Now everything will correctly clean
itself up when the module goes away after an executable gets rebuilt.

Now we correctly get rid of .o files that are used with the DWARF with 
debug map executables on subsequent runs since the only shared pointer
to the object files in from the DWARF symbol file debug map parser, and
when the module gets replaced, it destroys to old one along with all .o 
files. 

Also added a small optimization when using BSD archives where we will
remove old BSD containers from the shared list when they are outdated.

Sean Callanan 3bfdaa2a47 This patch modifies the expression parser to allow it
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.

  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.

Greg Clayton d4a2b37091 Huge memory and performance improvements in the DWARF parser.
Address ranges are now split up into two different tables: 
- one in DWARFDebugInfo that is compile unit specific
- one in each DWARFCompileUnit that has exact function DIE offsets

This helps keep the size of the aranges down since the main table will get
uniqued and sorted and have consecutive ranges merged. We then only parse the
compile unit one on demand once we have determined that a compile unit contains
the address in question. We also now use the .debug_aranges section if there 
is one instead of always indexing the DWARF manually.

NameToDIE now uses a UniqueCStringMap<dw_offset> map instead of a std::map.
std::map is very bulky as each node has 3 pointers and the key and value types.
This gets our NameToDIE entry down to 12 bytes each instead of 48 which saves
us a lot of memory when we have very large DWARF.

DWARFDebugAranges now has a smaller footprint for each range it contains to 
save on memory.

Greg Clayton c0a87652ba Added extra calls to the UniqueCStringMap to allow it to be used
more efficiently when it contains a large number of items. Since
the map is actually a vector of "const char *" and type T values,
it will double in size every time you append to it. The extra
added functions allow the collection to be sized to fit the data
after all entries have been appended, and lookups by name or by
regex have been built in to the class to allow efficient lookup.

Greg Clayton 14a3551aea Don't skip the application specific ~/.lldbinit file when the program
name is "lldb". So currently when you startup any application and you
have not specified that you would like to skip loading init files through
the API or from "lldb" options, then LLDB will try and load:

"~/.lldbinit-%s" where %s the basename of your program
"~/.lldbinit"

Then LLDB will load any program specified on the command line and then
source the "./.llbinit" file for any temporary debug session specific
commands.

I want this feature because I have thread and frame formats that do
ANSI color codes that I only want to load when running in a terminal
which is when I am running the "lldb" command line program.

in order to distinguish the real single step exception from a watchpoint exception
which uses the same exc_type of EXC_BREAKPOINT and exc_code of EXC_I386_SGL.

This is done by checking the debug status register to find out whether the watchpoint
data break event has fired, and, if yes, stuff the data break address into the exception's
exc_sub_code field on the debugserver side for lldb to consume on the other end.

Enrico Granata 9128ee2f7a Redesign of the interaction between Python and frozen objects:
- 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

Greg Clayton f9eec20bd3 Added support for accessing and loading our new .debug_names and .debug_types
DWARF accelerator table sections to the DWARF parser. These sections are similar
to the .debug_pubnames and .debug_pubtypes, but they are designed to be hash tables
that are saved to disc in a way that the sections can just be loaded into memory
and used without any work on the debugger side. The .debug_pubnames and .debug_pubtypes
sections are not ordered, contain a copy of the name in the section itself which
makes these sections quite large, they only include publicly exported names (so no
static functions, no types defined inside functions), many compilers put different
information in them making them very unreliable so most debugger ignore these sections
and parse the DWARF on their own. The tables must also be parsed and sorted in order 
to be used effectively. The new sections can be quickly loaded and very efficiently be used 
to do name to DIE lookups with very little up front work. The format of these new
sections will be changing while we work out the bugs, but we hope to have really 
fast name to DIE lookups soon.

Greg Clayton 8f258513a1 Fixed an assertion that could happen if we happened to parse a mach-o object
file that had a symbol that had a section specified where the section had
zero size. We now honor this section definition for the symbol and don't
assert anymore.

Johnny Chen d890bfc962 Add a new attribute self.lldbHere, representing the fullpath to the 'lldb' executable
built locally from the source tree.  This is distinguished from self.lldbExec, which
can be used by test/benchmarks to measure the performances against other debuggers.

You can use environment variable LLDB_EXEC to specify self.lldbExec to the dotest.py
test driver, otherwise it is going to be populated with self.lldbHere.

Modify the regular tests under test dir, i.e., not test/benchmarks, to use self.lldbHere.
Also modify the benchmarks tests to use self.lldbHere when it needs an 'lldb' executable
with debug info to do the performance measurements.

Enrico Granata 88da35f881 Improved the user-friendliness of errors shown by the summary feature in certain areas
Renamed format "signed decimal" to be "decimal". "unsigned decimal" remains unchanged:
 - the name "signed decimal" was interfering with symbol %S (use summary) in summary strings.
   because of the way summary strings are implemented, this did not really lead to a bug, but
   simply to performing more steps than necessary to display a summary. this is fixed.
Documentation improvements (more on synthetic children, some information on filters). This is still a WIP.

llvm-svn: 138384

Sean Callanan bccce81340 Added support for persistent types to the
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.

Sean Callanan 60dbc63a89 Restored the version of LLVM that we previously
rolled back, and the testcase that the rollback
broke.

The new LLVM has a new ARM disassembler, which
may cause instability.  Keeping the old one would
force us into a contorted position vis-a-vis the
LLVM sources we bring in, so we will address
issues on the new one rather than keeping the old
one around.
