Jason Molenda 6ab659a922 First part of an attempt to indicate to the user when they are
debugging optimized code.  Adds new methods on Function/SBFunction
to query whether a given function is optimized.  Adds a new
function.is-optimized format entity and changes the default 
frame-format to append "[opt]" if the function was built with
optimization.

The only indication that a binary was built with optimization
that we have right now is the presence of the DW_AT_APPLE_optimized
attribute (DW_FORM_flag value 1) in the DW_TAG_compile_unit.
The absence of this flag may mean that the compile_unit was not
compiled with optimization, or it may mean that the producer 
does not generate this attribute.

Currently this only works for dSYM debugging.  When we create
the CompileUnit with dwarf-in-.o-file debugging we don't have
the attribute value yet so it's not set.  I need to find the
flag value when we do start to read the .o file DWARF and 
set the CompileUnit's status at that point - but haven't 
done it yet.

I'm also going to add a mechanism for issuing warnings to users
such that they're only issued once in a debug session and 
there is away for users to suppress these warnings altogether
via .lldbinit file settings.  But I want to get this changeset
committed now that it's at a useful state.

Enrico Granata c1f705c229 Add a GetDisplayName() API to SBFrame, SBFunction and SBSymbol
This API is currently a no-op (in the sense that it has the same behavior as the already existing GetName()), but is meant long-term to provide a best-for-visualization version of the name of a function

It is still not hooked up to the command line 'bt' command, nor to the 'gui' mode, but I do have ideas on how to make that work going forward

Andrew Wilkins 7175f16cdb [lldb] Enable building with Cmake/BUILD_SHARED_LIBS
Summary:
Several changes to fix CMake builds of LLDB with the
BUILD_SHARED_LIBS setting on.

- Force all internal libraries to be built STATIC.
- Add additional library dependencies (pthread, dl,
  runtimedyld).
- modify finalisation of SWIG wrapper to symlink the
  "lib" dir into python/site-packages, so _lldb.so's
  RPATH resolves.

Test Plan: Verified one test case with "dotest.py".

llvm-svn: 238395
2015-05-28 04:55:53 +00:00
Greg Clayton 424a5dbc73 Added a new API to SBFrame:
lldb::addr_t SBFrame::GetCFA();

This gets the CFA (call frame address) of the frame so it allows us to take an address that is on the stack and figure out which thread it comes from.

Also modified the heap.py module to be able to find out which variable in a frame's stack frame contains an address. This way when ptr_refs finds a match on the stack, it get then report which variable contains the pointer.

Greg Clayton 4e1042e1bf Allow expresions to have unique expression prefixes:
expr_options = lldb.SBExpressionOptions()
expr_options.SetPrefix('''
struct Foo {
   int a;
   int b;
   int c;
}
'''
expr_result = frame.EvaluateExpression ("Foo foo = { 1, 2, 3}; foo", expr_options)

This fixed a current issue with ptr_refs, cstr_refs and malloc_info so that they can work. If expressions define their own types and then return expression results that use those types, those types get copied into the target's AST context so they persist and the expression results can be still printed and used in future expressions. Code was added to the expression parser to copy the context in which types are defined if they are used as the expression results. So in the case of types defined by expressions, they get defined in a lldb_expr function and that function and _all_ of its statements get copied. Many types of statements are not supported in this copy (array subscript, lambdas, etc) so this causes expressions to fail as they can't copy the result types. To work around this issue I have added code that allows expressions to specify an expression specific prefix. Then when you evaluate the expression you can pass the "expr_options" and have types that can be correctly copied out into the target. I added this as a way to work around an issue, but I also think it is nice to be allowed to specify an expression prefix that can be reused by many expressions, so this feature is very useful.

Zachary Turner 0405d68bb4 Use the debugginess of the python interpreter when symlinking _lldb.pyd.
Previously we would pass an argument to finishSwigWrapperClasses.py which
specified whether this was a debug or a release build.  But sometimes
CMAKE_BUILD_TYPE would not be set to anything, causing this argument
to be empty when passed in.  The only purpose of this argument was to
determine whether or not to append _d to the extension module when
creating the symlink.  This is only necessary when doing a debug
build of LLDB on Windows, which implies a debug interpreter, so we
replace this with a check to see if the running interpreter is a debug
one, and append _d if so.

Zachary Turner dd50f7421c Making linking against Python simpler on Windows.
This patch deprecates the three Python CMake variables in favor of
a single variable PYTHON_HOME which points to the root of a python
installation.  Since building Python doesn't output the files in
a structure that is compatible with the PYTHONHOME environment
variable, we also provide a script install_custom_python.py which
will copy the output of a custom python build to the correct
directory structure.

The supported workflow after this patch will be to build python
once for each configuration and architecture {Debug,Release} x {x86,x64}
and then run the script.  Then run CMake specifying -DPYTHON_HOME=<path>

The first time you do this will probably require you to delete your
CMake cache.

The old workflow is still supported during a transitionary period,
but a warning is printed at CMake time, and this will eventually
be removed.

Enrico Granata 9fe00e52d3 Bulk of the infrastructure work to allow script commands to be backed by object instances in addition to free functions
This works by creating a command backed by a class whose interface should - at least - include

def __init__(self, debugger, session_dict)
def __call__(self, args, return_obj, exe_ctx)

What works:
- adding a command via command script add --class
- calling a thusly created command

What is missing:
- support for custom help
- test cases

The missing parts will follow over the next couple of days

This is an improvement over the existing system as:
a) it provides an obvious location for commands to provide help strings (i.e. methods)
b) it allows commands to store state in an obvious fashion
c) it allows us to easily add features to script commands over time (option parsing and subcommands registration, I am looking at you :-)
