Johnny Chen 8cc80b2914 Followup check in for http://llvm.org/viewvc/llvm-project?rev=148491&view=rev,
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.

Johnny Chen 5928f64e2c Followup check in for http://llvm.org/viewvc/llvm-project?rev=148491&view=rev,
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.

Johnny Chen a28b89c700 rdar://problem/10712130
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.

Sean Callanan 20bb3aa53a The "desired result type" code in the expression
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.

Jim Ingham 73ca05a2a0 Add the ability to capture the return value in a thread's stop info, and print it

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.

Greg Clayton d1767f05b5 Added a new class called lldb_private::SymbolFileType which is designed to
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.

Greg Clayton ad9e828c89 <rdar://problem/10429064>
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
2011-11-29 04:03:30 +00:00
Greg Clayton c982b3d6e6 CommandObjectProcess was recently changed to automatically use the platform
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

Greg Clayton 2637f82542 Fixed an issue with the pthread_setspecific() where we weren't NULL-ing out
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.

Greg Clayton 144f3a9c90 Added a new class to Process.h: ProcessAttachInfo. This class contains enough
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.

Greg Clayton 2fc93eabf7 <rdar://problem/10338439>
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.

Greg Clayton c9ed478a39 Added the ability to run a process in a shell on MacOSX currently when using
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.

Enrico Granata 0a305db796 this patch addresses several issues with "command script" subcommands:
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

Greg Clayton dce502ede0 Fixed the Xcode project building of LLVM to be a bit more user friendly:
- 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.

Greg Clayton 5009f9d501 Added support for the new ".apple_objc" accelerator tables. These tables are
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.

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.

Johnny Chen 16dcf718d3 Add a commnad to set a condition for a watchpoint. Example:
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.

Johnny Chen 01a678603a SBValue::Watch() and SBValue::WatchPointee() are now the official API for creating
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.

Greg Clayton 20568dd981 Fixed a case where we might end up trying to parse a type in the DWARF parser for a method whose class isn't currently in the process of completing itself. Currently, methods of a class, must be parsed when the class type that contains the method is asked to complete itself through the clang::ExternalASTSource virtual functions. Now we "do the right thing" by checking if the class is being defined, and if so we parse it, else we tell the class to complete itself so everything happens correctly.

Greg Clayton 4f76b23764 Always use the full variable name when dumping globals since they might
be in namespaces.

Sean Callanan b6d70ebc0a Added ClangNamespaceDecl * parameters to several
core Module functions that the expression parser
will soon be using.
