to not be set by Process::WillPublicStop() so the driver won't get
access to them. The fix is straightforward, moving the call to
WillPublicStop above the early return for the interrupt case. (the
interrupt case does an early return because the rest of the function
is concerned with running stop hooks etc and those are not applicable
when we've interrupted the process).
Also added a test case for it. The test case is a little complicated
because I needed to drive lldb asynchronously to give the program
a chance to get up and running before I interrupt it. Running to
a breakpoint was not sufficient to catch this bug.

LLVM build trees export the gtest library through a special export set. If you're building against a build tree you shouldn't need to re-add gtest, but if you're building against an installed LLVM you do.

This diff
1. Adds a comment to ObjectFileELF.cpp about the current
approach to determining the OS.
2. Replaces the check in SymbolFileDWARF.cpp with a more robust one.
Test plan:
Built (on Linux) a test binary linked to a c++ shared library
which contains just an implementation of a function TestFunction,
the library (the binary itself) doesn't contain ELF notes
and EI_OSABI is set to System V.
Checked in lldb that now "p TestFunction()" works fine
(and doesn't work without this patch).

Rationale:
scripts/Python/modules: android is excluded at a higher level, so no point in
checking here
tools/lldb-mi: lldb-mi builds fine (with some cosmetic tweaks) on android, and
there is no reason it shouldn't.
tools/lldb-server: LLDB_DISABLE_LIBEDIT/CURSES already take the platform into
account, so there is no point in checking again.
I am reasonably confident this should not break the build on any platform, but
I'll keep an eye out on the bots.

In r288065, we added more report types into ASan that will be reported via the debugging API. This patch in LLDB provides human-friendly bug descriptions. This also improves wording on existing bug descriptions.

Summary:
This replaces all the uses of the __ANDROID_NDK__ define with __ANDROID__. This
is a preparatory step to remove our custom android toolchain file and rely on
the standard android NDK one instead, which does not provide this define.
Instead I rely, on __ANDROID__, which is set by the compiler.
I haven't yet removed the cmake variable with the same name, as we will need to
do something completely different there -- NDK toolchain defines
CMAKE_SYSTEM_NAME to Android, while our current one pretends it's linux.

We have a longstanding issue where the expression parser does not handle wide CFStrings (e.g., @"凸凹") correctly, producing the useless error message
Internal error [IRForTarget]: An Objective-C constant string's string initializer is not an array
error: warning: expression result unused
error: The expression could not be prepared to run in the target
This is just a side effect of the fact that we don't handle wide string constants when converting these to CFStringCreateWithBytes. That function takes the string's encoding as an argument, so I made it work and added a testcase.

Summary:
Since the function is way too big already, I tried at least to factor out the
timeout computation stuff into a separate function. I've tried to make the new
code semantically equivalent, and it also makes sense when I look at it as a done
deal.

The core of the function was actually handling them correctly. However, the
early exit was being too optimistic and did not give the function a chance to
fire if the path did not contain dots as well.
Fix that and add a couple of unit tests.

This changes most of the class to use the new Timeout class. The one function
left is RunThreadPlan, which I left for a separate change as the function is
massive. A couple of things to call out:
- I've renamed the affected functions to match the listener interface names. This
should also help catch any places I did not convert at compile time.
- I've deleted the WaitForState function as it was unused.
llvm-svn: 288241
Summary:
Communication classes use the Timeout<> class to specify the timeout. Listener
class was converted to chrono some time ago, but it used a different meaning for
a timeout of zero (Listener: infinite wait, Communication: no wait). Instead,
Listener provided separate functions which performed a non-blocking event read.
This converts the Listener class to the new Timeout class, to improve
consistency. It also allows us to get merge the different GetNextEvent*** and
WaitForEvent*** functions into one. No functional change intended.

We were referencing a the process class from a register context, which seems
intuitively wrong. Also, the comment above that code is now definitely incorrect,
as ProcessElfCore now does support floating point registers. Also, the code
wasn't really doing anything, as it was just skipping a zero-initialization of a
field that was most likely zero-initialized anyway. Linux elf core FPR test still
passes after this.
llvm-svn: 288237
Summary:
While adding FPR support to x86 elf core files (D26300), we ended up adding a
very x86-specific function to the general RegisterInfoInterface class, which I
didn't catch in review. This removes that function. The only reason we needed
it was to find the offset of the FXSAVE area. This is the same as the offset of
the first register within that area, so we might as well use that.

It seems a debug build of lldb-server will not complete without these, as the
linker is not able to strip out code that aggressively. Add those back until I
can figure out how to break the dependency chains.
llvm-svn: 288181
I don't believe the code in those plugins could be in any way useful for
lldb-server, but I can't be sure if this will break some transitive dependencies.
Builtbots should be able to tell us that.
llvm-svn: 288169
Summary:
This basically just inlines the LLDBDependencies.cmake file into lldb-server
CMakeLists.txt. The reason is that most of these dependencies are not actually
necessary for lldb-server (some of them can't be removed because of
cross-dependencies, but most of the plugins can). I intend to start cleaning
these up in follow-up commits, but I want to do this first, so the subsequent
ones can be easily reverted if they don't build in some configurations.
When I cleaned these up locally, I was able to get a 30%--50% improvement in
lldb-server size.

The current implementation of the decorator does not skip if the android target
arch is the same as host arch (as in both cases the platform comes out as linux).
Nonetheless android x86_64 binaries are not compatible with linux ones.
Technically this should be "skip if target is android and host is *not* android",
but currently nobody runs lldb test suite on an android host, so we don't even
have a way of specifying that the host is android.

Switch various bits of platform-specific code to chrono that I did not notice
when doing a linux build. This exposed a bug that ConnectionGenericFileWindows
did not handle the magic UINT32_MAX timeout value (instead it waited for about an
hour, which is close enough I guess). Fix that as well.
