When introduced, breakpoint names were just tags that you could
apply to breakpoints that would allow you to refer to a breakpoint
when you couldn't capture the ID, or to refer to a collection of
breakpoints.
This change makes the names independent holders of breakpoint options
that you can then apply to breakpoints when you add the name to the
breakpoint. It adds the "breakpoint name configure" command to set
up or reconfigure breakpoint names. There is also full support for
then in the SB API, including a new SBBreakpointName class.
The connection between the name and the breakpoints
sharing the name remains live, so if you reconfigure the name, all the
breakpoint options all change as well. This allows a quick way
to share complex breakpoint behavior among a bunch of breakpoints, and
a convenient way to iterate on the set.
You can also create a name from a breakpoint, allowing a quick way
to copy options from one breakpoint to another.
I also added the ability to make hidden and delete/disable protected
names. When applied to a breakpoint, you will only be able to list,
delete or disable that breakpoint if you refer to it explicitly by ID.
This feature will allow GUI's that need to use breakpoints for their
own purposes to keep their breakpoints from getting accidentally
disabled or deleted.

The auto-continue test was using the new (better) name
for providing commands (-C) but I haven't checked in that change
yet. Put the test back to the old way for now.

The main change is to avoid setting the process state as running when
debugging core/minidumps (details in the bug).
Also included a few small, related fixes around how the errors propagate in
this case.

On Windows a process can't delete its own current direcotry, that's why the test
needs to return to the original direcotry before removing newdir.

Summary:
Test was skipped because -data-evaluate-expression was thought
to not work on globals. This is not the case - the issue was clang
removes debug info for globals in cpp files that are not used.
Add a reference to the globals in question, and fix memory patter in
test to match memory pattern in testcase.

The FXSAVE member `ftw` (FPU Tag Word) was given the wrong size (8-bit)

This test is consistently reporting unexpected pass for me on FreeBSD

This is the FreeBSD equivalent of r238549.
This serves 2 purposes:
* LLDB should handle inferior process signals SIGSEGV/SIGILL/SIGBUS/
SIGFPE the way it is suppose to be handled. Prior to this fix these
signals will neither create a coredump, nor exit from the debugger
or work for signal handling scenario.
* eInvalidCrashReason need not report "unknown crash reason" if we have
a valid si_signo

You can get a breakpoint to auto-continue by adding "continue"
as a command, but that has the disadvantage that if you hit two
breakpoints simultaneously, the continue will force the process
to continue, and maybe even forstalling the commands on the other.
The auto-continue flag means the breakpoints can negotiate about
whether to stop.
Writing tests, I wanted to supply some commands when I made the
breakpoints, so I also added that ability.
llvm-svn: 309969
When an option was set at on a location, I was just copying the whole option set
to the location, and letting it shadow the breakpoint options. That was wrong since
it meant changes to unrelated options on the breakpoint would no longer take on this
location. I added a mask of set options and use that for option propagation.
I also added a "location" property to breakpoints, and added SBBreakpointLocation.{G,S}etCommandLineCommands
since I wanted to use them to write some more test cases.

Now -shlib flag can be provided alongside with names of symbols files:
(lldb) target symbols add --shlib stripper-lib.so unstripper-lib.so
This is helpful when default matching mechanisms by name and UUID
can't find a module, and the user needs to explicitly specify
which module the given symbol file belongs to.

This reapplies https://reviews.llvm.org/D35740 with a tweak to find
the section by name rather than type. Section types don't distinguish
between regular sections and their DWO counterparts.
llvm-svn: 308905
The DWO handling code can get confused by clang modules which also use
skeleton CUs to point to the object file with the full debug
info. This patch detects whether an object is a "real" DWO or a clang
module and prevents LLDB from interpreting clang modules as DWO. This
fixes the regression in TestWithModuleDebugging.

In NativeProcessLinux::MonitorSIGTRAP we were asserting that the si_code
value is one of the codes we know about. However, that list was very
incomplete -- for example, we were not handling SI_TKILL/SI_USER,
generated by raise(SIGTRAP). A cursory examination show there are at
least a dozen codes like these that an app can generate, and more can be
added at any point.
So, instead of trying to play catchup, I change the default behavior to
treat an unknown si_code like an ordinary signal. The only reason we
needed to inspect si_code in the first place is because
watchpoint/breakpoints are notified as SIGTRAP, but we already know
about those, and us starting to use a new debug event is far less likely
than somebody introducing a new non-debug event.
I add a test case to TestRaise to verify we are handling raise(SIGTRAP)
in an application properly.

Starting with android ndk r15, clang much more tests are affected by the
-mstackrealign bugl (now nearly all functions are affected, and not just
the ones requiring 16-byte alignment). Due to their numbers, Xfailing
all of them is not a viable option, so we will just have to declare this
configuration unsupported, and wait until ndk ships a clang version that
has this bug fixed.

All android builds systems have switched to -mstackrealign for building
x86 binaries, so follow their cue with our mini build system.
This presently breaks just one test (TestReturnValue), and this is due
to a compiler bug, which has already been fixed in clang, but it hasn't
made it yet into the official NDK compiler. While I'm touching that
test, I also remove an android-specific XFAIL, which is not relevant
anymore.

components to not depend on "." characters in the fileanme
(e.g. "Foundation.framework") but instead to just use path
separators. The names of the files themselves may have dots
in them ("com.apple.sbd") which would break the old scheme.
Also add a test case for this (macosx/find-dsym/bundle-with-dot-in-filename)
as well as a test case for r304520 (macosx/find-dsym/deep-bundle)
which needed a similar setup to test correctly on a single machine.
(both of these are really testing remote debug session situations
where the binary can't be found on the system where lldb is running,
complicating the test case a bit.)

This test started being flaky since r303848 (RunThreadPlan: Fix halting
logic in IgnoreBreakpoints = false). I am not reverting that, as I am
confident that actually fixed a problem. A more likely explanation is
that there is still one corner case that is not handled correctly there.
Marking the test as flaky until I get a chance to investigate. I also
mark the test as no-debug-info-dependend -- it stresses expression
evaluation, as far as debug info goes, the test if extremely simple.
