Stephen Wilson f3e78a3040 Simple makefile fixups.
With the current target revision of Clang libclangChecker no longer exists and
is not needed.  Update the include path so we can get at ARM_DWARF_Registers.h
and friends.

Johnny Chen ccc9963e34 Add an entry to the g_arm_opcodes table named emulate_sub_sp_imm which corresponds
to an operation to adjust the stack pointer (allocate space for local storage).

Johnny Chen 93b0c8b2aa Remove the expectedFailure decorator for the fixed bug:
rdar://problem/8435794
    settings set target.process.output-path does not seem to work

Also change the test case from test_set_output_path to test_set_error_output_path
as it now exercises both setting target.process.error-path and target.process.output-path.

Greg Clayton cdc7322bb1 Reverting recent thread resume changes as it was causing testing issues.
We will need to try again soon, but this change was causing instability.

Greg Clayton 4cd178020c Fixed an issue that was stopping LLDB from finding complete definitions for
types. What was happening was the DWARF parser was almost ignoring definitions
(DIEs with the DW_AT_declaration set to 1). It wasn't ignoring declarations
that had _some_ children. When this happened, we would treat the declaration
as a complete type. Often we would have a declaration of a type with just
some enum definitions inside and nothing else. Now we correctly ignore these
definitions, and also I added some changes to allow us to figure out what
decl context these special declarations actually point to.

Sean Callanan 9d2127ad3c Fixed a bug in the expression code which caused
it to interpret a "this" variable that was merely
a pointer -- that is, not a class pointer -- as
meaning that the current context was inside a C++
method.  This bug would prevent expressions from
evaluating correctly in regular C code if there
was a pointer variable named "this" in scope.

Greg Clayton 692538db26 One more thing... Resume any threads that we discover were created while we stop as
they may be in sensitive areas and we set breakpoints on the thread creation routines
if we are running expressions, so the threads should quickly get to a safe spot.

Greg Clayton 6f907e69e9 Deprecated old forms of SBTarget::Launch. There is not just one and no
SWIG renaming done to work around deprecated APIs.

llvm-svn: 124075
2011-01-23 17:46:22 +00:00
Johnny Chen c5826824b5 Let's teach SWIG to rename the overloaded SBTarget::Launch() function which has
provision for specifying a working directory with the name LaunchWithCWD in our
target language (Python) for now.  This fixes the test suite failures due to the
overloading.

Greg Clayton 03813a4e0d Restored some missing APIs for the test suite. Now testsuite still has some failures

Bumping Xcode project versions: lldb-42 and debugserver-127.

llvm-svn: 124063
2011-01-23 06:21:25 +00:00
Greg Clayton bd82a5d2cc Added a new variant of SBTarget::Launch() that deprectates the old one that
takes separate file handles for stdin, stdout, and stder and also allows for
the working directory to be specified.

Added support to "process launch" to a new option: --working-dir=PATH. We
can now set the working directory. If this is not set, it defaults to that
of the process that has LLDB loaded. Added the working directory to the
host LaunchInNewTerminal function to allows the current working directory 
to be set in processes that are spawned in their own terminal. Also hooked this
up to the lldb_private::Process and all mac plug-ins. The linux plug-in had its
API changed, but nothing is making use of it yet. Modfied "debugserver" and
"darwin-debug" to also handle the current working directory options and modified
the code in LLDB that spawns these tools to pass the info along.

Fixed ProcessGDBRemote to properly pass along all file handles for stdin, stdout
and stderr. 

After clearing the default values for the stdin/out/err file handles for
process to be NULL, we had a crasher in UserSettingsController::UpdateStringVariable
which is now fixed. Also fixed the setting of boolean values to be able to
be set as "true", "yes", "on", "1" for true (case insensitive) and "false", "no",
"off", or "0" for false.

Fixed debugserver to properly handle files for STDIN, STDOUT and STDERR that are not
already opened. Previous to this fix debugserver would only correctly open and dupe
file handles for the slave side of a pseudo terminal. It now correctly handles
getting STDIN for the inferior from a file, and spitting STDOUT and STDERR out to
files. Also made sure the file handles were correctly opened with the NOCTTY flag
for terminals.
