This could use some refinement still, but the previous behaviour of adding
-stdlib=libstc++ on FreeBSD w/ Clang is the least likely case to work.

llvm-svn: 200646
Fixes http://llvm.org/bugs/show_bug.cgi?id=18656.
Note this exposes a failure on Linux of
TestInferiorAssert.test_inferior_asserting_disassemble, similar to how
it fails on FreeBSD. I'll file a bug for this next. We're now getting
another frame beyond where we used to prior to this fix, so the fix is
exposing failures in previosly not-reachable frames.
Much thanks to Jason Molenda, who had much to do with helping figure
out where unwinding was breaking.

This change addresses shutdown crashes in the python lldb module when
the script interpreter was hanging on to saved file references after
leaving a session. It also gets rid of extra references to the
stdin/stdout/stderr python file objects that are created when entering
the session.
This change also moves the bundled pyexpect 2.4 library to the front
of the python library path so that a python distribution default
pyexpect (2.3 in Ubuntu 12.04) is not picked up first.
llvm-svn: 200486
The many many benefits include:
1 - Input/Output/Error streams are now handled as real streams not a push style input
2 - auto completion in python embedded interpreter
3 - multi-line input for "script" and "expression" commands now allow you to edit previous/next lines using up and down arrow keys and this makes multi-line input actually a viable thing to use
4 - it is now possible to use curses to drive LLDB (please try the "gui" command)
We will need to deal with and fix any buildbot failures and tests and arise now that input/output and error are correctly hooked up in all cases.

ValueObjectPrinter could enter an infinite loop while trying to display an aptly formed ValueObject: a reference, with a child of some pointer type, such that the pointees chain ended up pointing back to some part of itself - a pointer to itself being the simplest such case
Fixed here by only setting a pointer depth when needed, and ensuring that we won't overflow and wrap the pointer depth when it's zero.
llvm-svn: 200247
The alias test "exprf x 1234" expands to "expr -f x 1234" and is
expected to fail: it ends up trying to evaluate the invalid expression
void
$__lldb_expr(void *$__lldb_arg)
{
-f x 1234;
}
On FreeBSD LLDB ends up finding a static function f() in a math library,
and thus the error produced does not include "use of undeclared
identifier 'f'".
We will report failure to parse the expression in any case, so require
only that error message.

Part 1 changes PlatformLinux::CreateInstance to always create with
is_host=false; that method is only used as the plug-in creator method
associated with the remote-linux platform plugin, and should therefore
always be remote.
Part 1 patch by Steve Pucci.
Part 2: fix a test break on linux.
In test/functionalities/thread/thread_specific_break, when using gcc,
either C99 mode would need to be enabled, or the code would need to
change. I changed a couple loop variable definitions to conform
to pre-C99 to simplify testing the fix. The second issue was
the necessity to include -lpthread as a linker option in the Makefile.
Any issues with that part are due to me (Todd Fiala).

control to the user anyway. This was put in to handle monitors that would say there was no
stop reason when you first attached to them. But it broke the case where you hit a thread specific
breakpoint on many threads, but NOT the one specified in the breakpoint. I work around this
by only doing the junky override when the StopID is 0 - i.e. on first attach.
This commit also adds a test for thread specific breakpoints.

This new test case will detect this and make sure we don't regress on global name lookups that search all DWARF for everything when we don't need to.

The "type format add" command gets a new flag --type (-t). If you pass -t <sometype>, upon fetching the value for an object of your type,
LLDB will display it as-if it was of enumeration type <sometype>
This is useful in cases of non-contiguous enums where there are empty gaps of unspecified values, and as such one cannot type their variables as the enum type,
but users would still like to see them as-if they were of the enum type (e.g. DWARF field types with their user-reserved ranges)
The SB API has also been improved to handle both types of formats, and a test case is added
llvm-svn: 198105
test_convenience_registers_16bit_with_process_attach fails due to
pr18200. The test has a @expectedFailureFreeBSD decorator, but it
appears this does not catch a RuntimError exception raised in the test

it.

With this checkin, we use the installed clang compiler to build crashinfo.so from crashinfo.c upon every test suite execution
We also try to cleanup after ourselves, which of course will only work if the test suite does not actually crash
llvm-svn: 197106
Add an hook for the test suite into the OSX-only CrashReporter "App-specific info"
This allows the test suite to set the crash info to the name and file location of every test as the test gets executed
If the test suite crashes, the crash log will then report which test is the culprit, even when not using verbose mode
This only works on OSX, and defaults to not doing anything on other platforms, but OS/platform-specific invocations
can be devised by each individual platform
llvm-svn: 197095
This has led to many test suite failures because of copy and paste where new test cases were based off of other test cases and the "mydir" variable wasn't updated.
Now you can call your superclasses "compute_mydir()" function with "__file__" as the sole argument and the relative path will be computed for you.

@skipIfRemote is used to decorate test cases that don't make sense to run remotely.

lldb_private::Debugger was #including some "lldb/API" header files which causes tools (lldb-platform and lldb-gdbserver) that link against the internals only (no API layer) to fail to link depending on which calls were being used.
Also fixed the current working directory so that it gets set correctly for remote test suite runs. Now the remote working directory is set to: "ARCH/TESTNUM/..." where ARCH is the current architecture name and "TESTNUM" is the current test number.
Fixed the "lldb-platform" and "lldb-gdbserver" to not warn about mismatched visibility settings by having each have their own exports file which contains nothing. This forces all symbols to not be exported, and also quiets the linker warnings.
llvm-svn: 196141
A number of tests fail to build on FreeBSD because the test build script
defaults to libstdc++ for clang. On FreeBSD the libstdc++ is rather old
and libc++ should be used instead.
(These tests previously had an @expectedFailureFreeBSD decorator for
pr16696, the umbrella PR for the lack of threaded inferior support on
FreeBSD. The work to add that support will be committed soon.)
llvm-svn: 196101
Improved the detection of a valid GDB server where we actually can connect to a socket, but then it doesn't read or write anything (which happens with some USB mux software).
Host::MakeDirectory() now can make as many intermediate directories as needed.
The testsuite now has very initial support for remote test suite running. When running on a remote platform, the setUp function for the test will make a new directory and select it as the working directory on the remote host.
Added a common function that can be used to create the short option string for getopt_long calls.
llvm-svn: 195541
The failure to demangle 'anonymous namespace' on FreeBSD is fixed (twice)

It completes the job of using EvaluateExpressionOptions consistently throughout
the inferior function calling mechanism in lldb begun in Greg's patch r194009.
It removes a handful of alternate calls into the ClangUserExpression/ClangFunction/ThreadPlanCallFunction which
were there for convenience. Using the EvaluateExpressionOptions removes the need for them.
Using that it gets the --debug option from Greg's patch to work cleanly.
It also adds another EvaluateExpressionOption to not trap exceptions when running expressions. You shouldn't
use this option unless you KNOW your expression can't throw beyond itself. This is:
<rdar://problem/15374885>
At present this is only available through the SB API's or python.
It fixes a bug where function calls would unset the ObjC & C++ exception breakpoints without checking whether
they were set by somebody else already.
llvm-svn: 194182
Fixed the test case for "test/functionalities/exec/TestExec.py" on Darwin.
The issue was breakpoints were persisting and causing problems. When we exec, we need to clear out the process and target and start fresh with nothing and let the breakpoints populate themselves again. This patch correctly clears out the breakpoints and also flushes the process so that the objects (process/thread/frame) give out valid information.

One of the things that dynamic typing affects is the count of children a type has
Clear out the flag that makes us blindly believe the children count when a dynamic type change is detected
llvm-svn: 193663
This commit reimplements the TypeImpl class (the class that backs SBType) in terms of a static,dynamic type pair
This is useful for those cases when the dynamic type of an ObjC variable can only be obtained in terms of an "hollow" type with no ivars
In that case, we could either go with the static type (+iVar information) or with the dynamic type (+inheritance chain)
With the new TypeImpl implementation, we try to combine these two sources of information in order to extract as much information as possible
This should improve the functionality of tools that are using the SBType API to do extensive dynamic type inspection
llvm-svn: 193564
To make this work this patch extends LLDB to:
- Explicitly track the link_map address for each module. This is effectively the module handle, not sure why it wasn't already being stored off anywhere. As an extension later, it would be nice if someone were to add support for printing this as part of the modules list.
- Allow reading the per-thread data pointer via ptrace. I have added support for Linux here. I'll be happy to add support for FreeBSD once this is reviewed. OS X does not appear to have __thread variables, so maybe we don't need it there. Windows support should eventually be workable along the same lines.
- Make DWARF expressions track which module they originated from.
- Add support for the DW_OP_GNU_push_tls_address DWARF opcode, as generated by gcc and recent versions of clang. Earlier versions of clang (such as 3.2, which is default on Ubuntu right now) do not generate TLS debug info correctly so can not be supported here.
- Understand the format of the pthread DTV block. This is where it gets tricky. We have three basic options here:
1) Call "dlinfo" or "__tls_get_addr" on the inferior and ask it directly. However this won't work on core dumps, and generally speaking it's not a good idea for the debugger to call functions itself, as it has the potential to not work depending on the state of the target.
2) Use libthread_db. This is what GDB does. However this option requires having a version of libthread_db on the host cross-compiled for each potential target. This places a large burden on the user, and would make it very hard to cross-debug from Windows to Linux, for example. Trying to build a library intended exclusively for one OS on a different one is not pleasant. GDB sidesteps the problem and asks the user to figure it out.
3) Parse the DTV structure ourselves. On initial inspection this seems to be a bad option, as the DTV structure (the format used by the runtime to manage TLS data) is not in fact a kernel data structure, it is implemented entirely in useerland in libc. Therefore the layout of it's fields are version and OS dependent, and are not standardized.
However, it turns out not to be such a problem. All OSes use basically the same algorithm (a per-module lookup table) as detailed in Ulrich Drepper's TLS ELF ABI document, so we can easily write code to decode it ourselves. The only question therefore is the exact field layouts required. Happily, the implementors of libpthread expose the structure of the DTV via metadata exported as symbols from the .so itself, designed exactly for this kind of thing. So this patch simply reads that metadata in, and re-implements libthread_db's algorithm itself. We thereby get cross-platform TLS lookup without either requiring third-party libraries, while still being independent of the version of libpthread being used.
Test case included.

Extend DummySyntheticProvider to actually use debug-info vended children as the source of information

This radar extends the notion of one-liner summaries to automagically apply in a few interesting cases
More specifically, this checkin changes the printout of ValueObjects to print on one-line (as if type summary add -c had been applied) iff:
this ValueObject does not have a summary
its children have no synthetic children
its children are not a non-empty base class without a summary
its children do not have a summary that asks for children to show up
the aggregate length of all the names of all the children is <= 50 characters
you did not ask to see the types during a printout
your pointer depth is 0
This is meant to simplify the way LLDB shows data on screen for small structs and similarly compact data types (e.g. std::pair<int,int> anyone?)
Feedback is especially welcome on how the feature feels and corner cases where we should apply this printout and don't (or viceversa, we are applying it when we shouldn't be)
llvm-svn: 191996
- test wasn't checking for a stop reason before issuing the 'script' command

llvm-svn: 191708
DumpValueObject() 2.0
This checkin restores pre-Xcode5 functionality to the "po" (expr -O) command:
- expr now has a new --description-verbosity (-v) argument, which takes either compact or full as a value (-v is the same as -vfull)
When the full mode is on, "po" will show the extended output with type name, persistent variable name and value, as in
(lldb) expr -O -v -- foo
(id) $0 = 0x000000010010baf0 {
1 = 2;
2 = 3;
}
When -v is omitted, or -vcompact is passed, the Xcode5-style output will be shown, as in
(lldb) expr -O -- foo
{
1 = 2;
2 = 3;
}
- for a non-ObjectiveC object, LLDB will still try to retrieve a summary and/or value to display
(lldb) po 5
5
-v also works in this mode
(lldb) expr -O -vfull -- 5
(int) $4 = 5
On top of that, this is a major refactoring of the ValueObject printing code. The functionality is now factored into a ValueObjectPrinter class for easier maintenance in the future
DumpValueObject() was turned into an instance method ValueObject::Dump() which simply calls through to the printer code, Dump_Impl has been removed
Test case to follow

- Removes the block in UnwindLLDB::AddOneMoreFrame that tests for a bad stack setup,
since it is neither correct (tests the FP GPR), complete (doesn't consider multi-frame

where either of the two (why just two?) previous frames have the same canonical frame
address as the frame that we propose adding to the stack).

to build out the symbol table as addresses are used, and implements
the mechanism for ELF to add stripped symbols from eh_frame.
Uses this mechanism to allow disassembly for addresses corresponding
to stripped symbols for ELF, and provide hooks to implement this for
PE COFF.
Also removes eSymbolContextTailCall in favor of an option for
ResolveSymbolContextForAddress for consistency with the documentation
for eSymbolContextEverything. Essentially, this is just an option for
interpreting the so_addr.
llvm-svn: 191307
Specifically, allows the unwinder to handle the case where sc.function
gets resolved with a pc that is one past the address range of the function
(consistent with a tail call). However, there is no matching symbol.
Adds eSymbolContextTailCall to provide callers with control over the scope
of symbol resolution and to allow ResolveSymbolContextForAddress to handle
tail calls since this routine is common to unwind and disassembly.

Summary:
This merge brings in the improved 'platform' command that knows how to
interface with remote machines; that is, query OS/kernel information, push

communication packets that back that interface, at least on Darwin based
operating systems via the POSIXPlatform class. Linux support is coming soon.
Verified the test suite runs cleanly on Linux (x86_64), build OK on Mac OS
X Mountain Lion.
Additional improvements (not in the source SVN branch 'lldb-platform-work'):
- cmake build scripts for lldb-platform
- cleanup test suite
- documentation stub for qPlatform_RunCommand
- use log class instead of printf() directly
- reverted work-in-progress-looking changes from test/types/TestAbstract.py that work towards running the test suite remotely.
- add new logging category 'platform'

A long time ago we start with clang types that were created by the symbol files and there were many functions in lldb_private::ClangASTContext that helped. Later we create ClangASTType which contains a clang::ASTContext and an opauque QualType, but we didn't switch over to fully using it. There were a lot of places where we would pass around a raw clang_type_t and also pass along a clang::ASTContext separately. This left room for error.
This checkin change all type code over to use ClangASTType everywhere and I cleaned up the interfaces quite a bit. Any code that was in ClangASTContext that was type related, was moved over into ClangASTType. All code that used these types was switched over to use all of the new goodness.

The semi-unofficial way of returning a status from a Python command was to return a string (e.g. return "no such variable was found") that LLDB would pick as a clue of an error having happened
This checkin changes that:
- SBCommandReturnObject now exports a SetError() call, which can take an SBError or a plain C-string
- script commands now drop any return value and expect the SBCommandReturnObject ("return object") to be filled in appropriately - if you do nothing, a success will be assumed

No more fighting about whether the progress bar is good or bad :-)

Now, the way SWIG wrappers call into Python is through a utility PyCallable object, which overloads operator () to look like a normal function call
Plus, using the SBTypeToSWIGWrapper() family of functions, we can call python functions transparently as if they were plain C functions
Using this new technique should make adding new Python call points easier and quicker
The PyCallable is a generally useful facility, and we might want to consider moving it to a separate layer where other parts of LLDB can use it

dematerialization of registers that caused
conditional breakpoint expressions not to
work properly. Also added a testcase.

This ensures that we won't try to do cleanups of test cases that we are skipping
e.g. this brings down the time required to run the cmdline category on my machine from ~70s to ~30s

This is a rewrite of the command history facility of LLDB
It takes the history management out of the CommandInterpreter into its own CommandHistory class
It reimplements the command history command to allow more combinations of options to work correctly (e.g. com hist -c 1 -s 5)
It adds a new --wipe (-w) option to command history to allow clearing the history on demand
It extends the lldbtest runCmd: and expect: methods to allow adding commands to history if need be
It adds a test case for the reimplemented facility

Improved the makefile "clean" to include deleting all ".d.[0-9]+" files.
Added options to the "lldb/examples/lookup" example and made it build using the LLDB_BUILD_DIR. If this is not set, it will default to "/Applications/Xcode.app/Contents/SharedFrameworks" on Darwin.
Added options to the "lldb/examples/function" example and made it build using the LLDB_BUILD_DIR.

- skip the attach cases in TestRegisters.py -- caused slowness/sigabrt
- fixed log file removal function (in case test is run with -# flag)

Modified the test programs to use floating point constants that always will display correctly. We had some numbers that were being rounded, and now that we are using clang, we no longer round them and we get more correct results.
