Fixed the test case to use a runtime function prototype that will be correct ([NSString stringWithCString: "new"]) instead of one that won't (expression str = [NSString stringWithFormat: @"%cew", 'N']). The runtime doesn't track vararg functions correctly so we can't reconstitute the function correctly.
Also fixed some expressions that used "str_id" whose type was "id" and do the necessary casting since "id" doesn't have any methods.

Now that llgs supports communicating the 0-port choose-a-port
mechanism and can communicate that back to a caller via the
--named-pipe option (at parity with debugserver), we use this
mechanism to always start llgs and debugserver gdb-remote
protocol tests without needing to use some port arbitration
mechanism. This eliminates some potential intermittent failures vs. the
previous random port and collision-avoidance strategy used.

The testrun now completes successfully on my FreeBSD 11.0-CURRENT
laptop. There are some intermittent failures on the FreeBSD buildbot
still, which should be addressed in later commits.

The --setsid (-S) option changes the session id for the lldb-gdbserver process.
This is used by tools such as lldb-platform and allows the user to prevent
llgs from being in the same session as a calling terminal session.
This will prevents terminal group control signals from affecting
lldb-gdbserver.

Added a unit test to test debugserver and llgs compliance on --named-pipe support.
Modified llgs to implement --named-pipe support. (Note: need to revisit with
new generic pipe support).

The following intermittently-failing tests have been flipped from
skip to XFAIL on some combo of Linux and MacOSX:
TestCallStopAndContinue.py (Linux, MacOSX)
TestCallWithTimeout.py (Linux)
TestConvenienceVariables.py (Linux)
TestStopHookMultipleThreads.py (Linux)
The following new tests have been marked XFAIL but are just
intermittently failing:
TestMultipleDebug.py (definitely intermittent on MacOSX, not sure I've seen
it pass yet on Linux)

debug sessions simultaneously to expose race conditoin/locking
issues.
This directory has an inferior program, testprog.cpp that has a
couple of functions we can put breakpoints on.
It has a driver program, multi-process-driver.cpp, which links
against the LLDB solib and uses the SB APIs. It creates 50 pthreads,
creates a debugger on all of them, launches a debug session of the
inferior testprog, hits a couple breakpoints, walks the stack,
continues, etc., and then kills the inferior and ends the debug
session.
A pass is if all fifty debug sessions complete successfully
in the alloted time (~60 seconds).
We may need to tweak this one to work correctly on different
platforms/targets but I wanted to get it checked in to start.
llvm-svn: 212671
Marked skipped for Linux:
TestCallStopAndContinue
TestConvenienceVariables
TestStopHookMultipleThreads
Fixed up gdb-remote port-grabbing code to use a random port in a wide range,
and to allow that to fail more gracefully. This appears to have solved some
gdb-remote intermittent failing behavior.
llvm-svn: 212662
All tests matching '-p TestObjCMethods' now are marked correctly for MacOSX, and some
error classes have been removed in cleanup code looking for files that
might not exist due to previous failure.

On MacOSX, we need to adjust the way we clean up the crashlog dylib in deleteCrashInfoDylib().
Right now it is only geared to run one test at a time. For now I'm just skipping the delete.
I'll work with Apple on a fix that handles this. It seems to only cause one dylib total to
hang around that might otherwise have been deleted. Fixes MacOSX multiple tests running
at the same time. (I didn't hit this on Yosemite, might be an issue that only shows up
on Mavericks?)
llvm-svn: 212548
This change modifies the way the multi-threaded test runner works.
It uses the Python multiprocessing library rather than the threading
library. Investigation showed that all MacOSX threads were waiting on
the global python lock when using the threading approach. Not sure
why that differed from the Linux/FreeBSD implementations.
The new approach uses the multiprocessing library's Pool class. It's
mildly cleaner than the other version, runs multithreaded on MacOSX,
and seems to have caused no performance regression on Linux. The
worker thread logic is simpler with the Pool managing the worker
processes.
This also includes a minor change to the test runner's python
lldb dir logic using the -P option. It now looks at the last line
of output rather than the first line. This covers part of the issue
of extra options validation logic getting spit out. The test runner
will now pick up the right python library directory. It does not
fix all the issues, though, as a ton of tests (50+ on Linux) are
failing due to unexpected output when running lldb.

This change brings in lldb-gdbserver (llgs) specifically for Linux x86_64.
(More architectures coming soon).
Not every debugserver option is covered yet. Currently
the lldb-gdbserver command line can start unattached,
start attached to a pid (process-name attach not supported yet),
or accept lldb attaching and launching a process or connecting
by process id.
The history of this large change can be found here:

Until mid/late April, I was not sharing the work and continued
to rebase it off of head (developed via id tfiala@google.com). I switched over to
user todd.fiala@gmail.com in the middle, and once I went to github, I did
merges rather than rebasing so I could share with others.
llvm-svn: 212069
Also added tests for presence of vCont;c, vCont;C, vCont;s, vCont;S as
returned by vCont? query.
Broke out single step functionality from TestLldbGdbServer into base class.
Used by new TestGdbRemoteSingleStep (using $s) and TestGdbRemote_vCont.
Also part of llgs wrap-up, see:

Removed the distribution EXEs from FreeBSD and Ubuntu.
Added a hello-world .cpp file, and compiled it for
several platform/compiler variants:
Ubuntu 14.04 x86_64, clang 3.5 (the ubuntu1 3.5 pre variant)
Ubuntu 14.04 x86_64, gcc 4.8.2
FreeBSD 10.0 x86_64, clang 3.3
FreeBSD 10.0 x86_64, gcc 4.7.3
NetBSD 6.1 x86_64, gcc 4.5.3
I also added the NetBSD expected architecture and triple.
Note I have NetBSD not appending the version info to the
OS name, in contrast to FreeBSD.
llvm-svn: 211954
Previously ObjectFileELF was simplifying and assuming the object file it was
looking at was the same as the host architecture/triple. This would break
attempts to run, say, lldb on MacOSX against lldb-gdbserver on Linux since
the MacOSX lldb would say that the linux elf file was really an Apple MacOSX
architecture. Chaos would ensue.
This change allows the elf file to parse ELF notes for Linux, FreeBSD and
NetBSD, and determine the OS appropriately from them. It also initializes
the OS type from the ELF header OSABI if it is set (which it is for FreeBSD
but not for Linux).
Added a test with freebsd and linux images that verify that
'(lldb) image list -t -A' prints out the expected architecture for each.
llvm-svn: 211907
I missed adding a few new files to the change list.
The build is broken from r211526 without this fix.
(And Ed Maste caught it before I did, so this is
the remainder - the test methods).
llvm-svn: 211535
Tests for both thread suffix and no thread suffix execution.
Moved some bit-flipping helper methods from TestLldbGdbServer
into the base GdbRemoteTestCaseBase class.
llvm-svn: 211381
Fixes two causes for https://github.com/tfiala/lldb/issues/7.
1. Ensures the inferior program has started executing, by printing
a message on output first thing (per the "message:" command line arg)
and waiting for that text to arrive before doing any checks related
to auxv support.
2. Fixes up auxv-related regex patterns to be compiled with the Python
re.MULTILINE and re.DOTALL options. The multiline is needed because
the binary data can include what look like newlines when interpreted
as text, and the DOTALL is needed to have the (.*) content portion match
newlines.
Added interrupt packet helper methods to add interrupt test sequence
packets and parse the results from them.
llvm-svn: 211283
First batch of auxv-related tests from llgs branch.
Includes helpers for unescaping gdb-remote binary-escaped
data, converting binary data from inferior endian-ness to
integral values, etc.
Tests on debugserver are expected to be skipped since it
doesn't support auxv and the tests are geared to be skipped
on platforms that don't broadcast support for the feature
in qSupported. (llgs is listed as XFAIL since qSupported
support in llgs upstream is not there, so the support check
cannot work in upstream llgs.)
llvm-svn: 211105
The llgs branch had a bug where register sets were not terminated with
LLDB_INVALID_REGNUM so the expedite register loop was issuing duplicate
registers. This test was added to catch the problem.
Enhanced the key-val collection method to optionally (and by default)
support capturing duplicate values for a given key. When that happens
and if permitted, it promotes a single key to a list and appends values
to it.
