logic that supported calling functions with arbitrary
arguments. We use ClangFunction for this, and the
low-level logic is only required to support one or two
pointer arguments.

thread basic info state and not realize that a thread was already suspended
or if a thread was starting up and not ready to be displayed to the user
(in an uninterruptable state). If it is not user ready yet, we don't add it
to our list of threads that can be played with.

namespaces by name given an optional symbol context. I might end up
dressing up the "clang::NamespaceDecl" into a lldb_private::Namespace
class if we need to do more than is currenlty required of namespaces.
Currently we only need to be able to lookup a namespace by name when
parsing expressions, so I kept it simple for now. The idea here is
even though we are passing around a "clang::NamespaceDecl *", that
we always have it be an opaque pointer (it is forward declared inside
of "lldb/Core/ClangForward.h") and we only use clang::NamespaceDecl
implementations inside of ClangASTContext, or ClangASTType when we need
to extract information from the namespace decl object.
llvm-svn: 118737
comes from by using a virtual function to provide it from the Module's
SymbolVendor by default. This allows the DWARF parser, when being used to
parse DWARF in .o files with a parent DWARF + debug map parser, to get its
type list from the DWARF + debug map parser so when we go and find full
definitions for types (that might come from other .o files), we can use the
type list from the debug map parser. Otherwise we ended up mixing clang types
from one .o file (say a const pointer to a forward declaration "class A") with
the a full type from another .o file. This causes expression parsing, when
copying the clang types from those parsed by the DWARF parser into the
expression AST, to fail -- for good reason. Now all types are created in the
same list.
Also added host support for crash description strings that can be set before
doing a piece of work. On MacOSX, this ties in with CrashReporter support
that allows a string to be dispalyed when the app crashes and allows
LLDB.framework to print a description string in the crash log. Right now this
is hookup up the the CommandInterpreter::HandleCommand() where each command
notes that it is about to be executed, so if we crash while trying to do this
command, we should be able to see the command that caused LLDB to exit. For
all other platforms, this is a nop.
llvm-svn: 118672
Fixed the DWARF plug-in such that when it gets all attributes for a DIE, that
it omits the DW_AT_sibling and DW_AT_declaration when getting attributes
from a DW_AT_abstract_origin or DW_AT_specification DIE.

invoke the test driver to rerun the very same test. Example output:

to not get resolved.
Fixed the "void **isa_ptr" variable inside the objective C verifier to start
with a '$' character so we don't go looking for it in our program.
Moved the lookup for "$__lldb_class" into the part that knows we are looking
for internal types that start with a '$'.

I only did a tiny bit of testing; in the one case I tried changing the
contents of a radar in the middle of a stack and it was still current in
the live register context so it filtered down to frame 0 and was handed
over to the live register set RegisterContext. I need to test a case
where a register is saved on the stack in memory before I check this
one off.
llvm-svn: 118486
the frame count is requested or each frame is individually requested.
In practice this doesn't seem to help anything because we have
functions like StackFrameList::GetNumFrames() which is going to
request each frame anyway. And classes like ThreadPlanStepRange
and ThreadPlanStepOverRange get the stack depth in their ctor forcing
a full stack walk. But at least UnwindLLDB will delay doing a full
walk if it can.

FuncUnwinders object if the eh_frame section was missing
from an objfile. Worked fine on x86_64 but on i386 where
eh_frame is unusual, that resulted in the arch default
UnwindPlan being used all the time instead of picking up
an assembly profile based unwindplan.

failed/errored tests at the start of the test run, in case the test run crashes

a pseudo terminal even when the process being attached to.
Fixed a possible crasher in the in:
bool
ClangASTContext::IsAggregateType (clang_type_t clang_type);
It seems that if you pass in a record decl, enum decl, or objc class decl
and ask it if it is an aggregate type, clang will crash.

the same architecture as a default program, the attach architecture auto
detection would change the architecture to the architecture of the darwin-debug

we want to run just the instance of testclass-testmethod combination and nothing else.
Specifying '-g' now will admit the whole .py test module if it does not contain a matching
testclass-testmethod combination at all.
This option arrangement adheres to the RISC principle of making the common cases fast. :-)

every external variable reference in the module,

and "/private/tmp/a.c". This was done by adding a "mutable bool m_is_resolved;"
member to FileSpec and then modifying the equal operator to check if the
filenames are equal, and if they are, then check the directories. If they are
not equal, then both paths are checked to see if they have been resolved. If
they have been resolved, we resolve the paths in temporary FileSpec objects
and set each of the m_is_resolved bools to try (for lhs and rhs) if the paths
match what is contained in the path. This allows us to do more intelligent
compares without having to resolve all paths found in the debug info (which
can quickly get costly if the files are on remote NFS mounts).
llvm-svn: 118387
where the DWARF is in the .o files so they can track down the actual type for
a forward declaration. This was working before for just DWARF files, but not
for DWARF in .o files where the actual definition was in another .o file.
Modified the main thread name in the driver to be more consistent with the
other LLDB thread names.
llvm-svn: 118383
don't crash if we disable logging when some code already has a copy of the
logger. Prior to this fix, logs were handed out as pointers and if they were
held onto while a log got disabled, then it could cause a crash. Now all logs
are handed out as shared pointers so this problem shouldn't happen anymore.
We are also using our new shared pointers that put the shared pointer count
and the object into the same allocation for a tad better performance.

thread descriptions. This allows for correctly finding and obeying the last
filename-and-line marker from the debugger.
Add a delay for gud-up and gud-down. This makes tracking filename-and-line

that check pointer validity fail to parse. Now
lldb does not crash in that case. Also added
support for checking Objective-C class validity
in the Version 1 runtime as well as Version 2
runtimes with varying levels of available debug
support.
llvm-svn: 118271
fixed them. Added DISALLOW_COPY_AND_ASSIGN to classes that should
not be bitwise copied. Added default initializers for member
variables that weren't being initialized in the ctor. Fixed a few
shadowed local variable mistakes.
llvm-svn: 118240
adding support into lldb_private::Process:
virtual uint32_t
lldb_private::Process::LoadImage (const FileSpec &image_spec,
Error &error);
virtual Error
lldb_private::Process::UnloadImage (uint32_t image_token);
There is a default implementation that should work for both linux and MacOSX.
This ability has also been exported through the SBProcess API:
uint32_t
lldb::SBProcess::LoadImage (lldb::SBFileSpec &image_spec,
lldb::SBError &error);
lldb::SBError
lldb::SBProcess::UnloadImage (uint32_t image_token);
Modified the DynamicLoader plug-in interface to require it to be able to
tell us if it is currently possible to load/unload a shared library:
virtual lldb_private::Error
DynamicLoader::CanLoadImage () = 0;
This way the dynamic loader plug-ins are allows to veto whether we can
currently load a shared library since the dynamic loader might know if it is
currenlty loading/unloading shared libraries. It might also know about the
current host system and know where to check to make sure runtime or malloc
locks are currently being held.
Modified the expression parser to have ClangUserExpression::Evaluate() be
the one that causes the dynamic checkers to be loaded instead of other code
that shouldn't have to worry about it.
llvm-svn: 118227
RegisterContextLLDB holds a reference to the SymbolContext
in the vector of Cursors that UnwindLLDB maintains. Switch
UnwindLLDB to hold a vector of shared pointers of Cursors
so this reference doesn't become invalid.
Correctly falling back from the "fast" UnwindPlan to the
"full" UnwindPlan when additional registers need to be
retrieved.

local variable and an argument variable.
Add ValueTypeString() utility function into lldbutil.py which converts the enum

Modify TestBase.DebugSBValue() to also dump the value type of an SBValue object.
