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
If your commands were relying on returning a value and having LLDB pick that up as an error, please change your commands to SetError() through the return object or expect changes in behavior

Set your env variable LLDB_TEST_ARGUMENTS to one or more options to be passed to the lldb test suite and those will be picked automatically
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.

that is patterned after its parent TestInferiorCrashing.py.
- The xfail decorator limits the xfail to tool-chains that support this compiler option.
- Included a TODO concerning the platform-specific behavior when 'next' is issued after a crash.
- Toggling -fomit-frame-pointer results in an xpass as mentioned in pr15415.
Thanks to Daniel for the review, and Samuel for the bug report and reproducer.

- For instance, allows 'gcc' to match x86-64-linux-gnu-gcc as required on some Debian builds.
- Also adds doc-strings and a more consistent naming convention for related helpers.
llvm-svn: 183415
- Implemented the SExt instruction, and
- eliminated redundant codepaths for constant
handling.
Added test cases.

- one test case is due to llvm.org/pr16229
- other test case uses a Linux workaround for above by using os.fork() instead of subprocess module

Adding data formatters for std::set, std::multiset and std::multimap for libc++
The underlying data structure is the same as std::map, so this change is very minimal and mostly consists of test cases
llvm-svn: 183323
If you want to define a formatter for "array of Foo of any size", ordinarily you would say
-x "Foo \[[0-9]+\]"
this checkin allows you to instead say "Foo[]" (or "Foo []") and LLDB will automatically create the regular expression and add the -x flag on your behalf
llvm-svn: 183272
Fixing an issue where formats would not propagate from parents to children in all cases
Details follow:
an SBValue has children and those are fetched along with their values
Now, one calls SBValue::SetFormat() on the parent
Technically, the format choices should propagate onto the children (see ValueObject::GetFormat())
But if the children values are already fetched, they won't notice the format change and won't update themselves
This commit fixes that by making ValueObject::GetValueAsCString() check if any format change intervened from the previous call to the current one
A test case is also added

command script import now does reloads - for real
If you invoke command script import foo and it detects that foo has already been imported, it will
- invoke reload(foo) to reload the module in Python
- re-invoke foo.__lldb_init_module
This second step is necessary to ensure that LLDB does not keep cached copies of any formatter, command, ... that the module is providing
Usual caveats with Python imports persist. Among these:
- if you have objects lurking around, reloading the module won't magically update them to reflect changes
- if module A imports module B, reloading A won't reload B
These are Python-specific issues independent of LLDB that would require more extensive design work
The --allow-reload (-r) option is maintained for compatibility with existing scripts, but is clearly documented as redundant - reloading is always enabled whether you use it or not
