Robert Flack e49b8e065e Call remote platform GetSupportedArchitectureAtIndex if connected to remote.
Updated PlatformLinux::GetSupportedArchitectureAtIndex to call the
PlatformRemoteGdbServer::GetSupportedArchitectureAtIndex if connected remotely.
This should return the correct thing for android (to fix those failing tests),
and is also working for mac to linux.

Test Plan:
./dotest.py $DOTEST_OPTS -t -p TestCallStdStringFunction.py
The above still passes when running mac->linux indicating it successfully
identified PlatformLinux as the target platform and converted the mmap options
correctly.

Ted Woodward b1da257ad1 Remove Triple Vendor check when creating Linux Platform
Summary: The Linux Platform shouldn't care about the Vendor field in the Triple. Currently it allows a value of "PC", or "unknown" if LLDB was built on Linux. This patch removes that check, so the Vendor field isn't touched. This will allow the Linux Platform to be created when using a Triple of *-*-Linux.

Previously the remote module sepcification was fetched only from the
remote platform. With this CL if we have a remote process then we ask it
if it have any information from a given module. It is required because
on android the dynamic linker only reports the name of the SO file and
the platform can't always find it without a full path (the process can
do it based on /proc/<pid>/maps).

Ilia K e4af28b7e9 Fix SDK selection using "platform select" when --sysroot/--version/--build options were specified
Summary:
This patch fixes SDK selection in the following case:
```
platform select remote-ios --sysroot "/Users/IliaK/Library/Developer/Xcode/iOS DeviceSupport/8.1.2 (12B440)" --build 12B440 --version 8.1.2
target create --arch arm64 "~/Project1.app"
```

Currently the lldb selects a first SDK version (in name order) in directory and then updates it after the device is connected. This approach ignores user's arguments and actually "platform select" command doesn't make sense.

After this patch, lldb takes a SDK which matches to user's arguments.

Pavel Labath 78521ef545 Fix race condition with -o "process launch" on linux
Summary:
starting a debug session on linux with -o "process launch" lldb parameter was failing since
Target::Launch (in sychronous mode) is expecting to be able to receive public process events.
However, PlatformLinux did not set up event hijacking on process launch, which caused these
events to be processed elsewhere and left Target::Launch hanging. This patch enables event
interception in PlatformLinux (which was commented out).

Upon enabling event interception, I noticed an issue, which I traced back to the inconsistent
state of public run lock, which remained false even though public and private process states were
"stopped". I addressed this by making sure the run lock is "stopped" upon exit from
WaitForProcessToStop (which already had similar provisions for other return paths).

Test Plan: This should fix the intermittent TestFormats failure we have been experiencing on Linux.

Vince Harron bc477ddee0 Linux - debugging of local processes via lldb-gdbserver
Instead of lldb calling the ptrace APIs directly, it launches an llgs
instance and communicates with it via the remote debug protocol.

This has two advantages.

There is more code shared between the remote debugging code path
and the local debugging code path. If a feature works in remote, it
probably works locally and vice-versa.

It makes us more architecturally similar to OSX (which also does
local debugging via a connection to debugserver).

This path is called LLGS local. We think that this configuration is
now at parity with (or better than) local linux debugging.

It is currently invoked if you have an environment variable defined
"PLATFORM_LINUX_FORCE_LLGS_LOCAL"

We would like to switch to LLGS local as the default path and only
use the non-LLGS path if someone has an environment variable defined
"PLATFORM_LINUX_DISABLE_LLGS_LOCAL"

Later, if all goes well, we would like to remove non-LLGS local
debugging support to simplify the codebase and avoid confusion.

- Modified all places that use the SBLaunchInfo/SBAttachInfo and the internal ProcessLaunchInfo/ProcessAttachInfo to not take a listener as a parameter since it is in the launch/attach info now
- Load a module's sections by default when removing a module from a target. Since we create JIT modules for expressions and helper functions, we could end up with stale data in the section load list if a module was removed from the target as the section load list would still have entries for the unloaded module. Target now has the following functions to help unload all sections a single or multiple modules:

    size_t
    Target::UnloadModuleSections (const ModuleList &module_list);

    size_t
    Target::UnloadModuleSections (const lldb::ModuleSP &module_sp);

Jason Molenda 22975a28ac A pretty big overhaul of the TryFallbackUnwindPlan method in
RegisterContextLLDB.  I have core files of half a dozen tricky
unwind situations on x86/arm and they're all working pretty much
correctly at this point, but we'll need to keep an eye out for
unwinder regressions for a little while; it's tricky to get these
heuristics completely correct in all unwind situations.

Summary:
Ed Maste found some problems with the commit in D5988.  Address most of these.
While here, also add floating point return handling.  This doesn't handle
128-bit long double yet.  Since I don't have any system that uses it, I don't
currently have plans to implement it.

Justin Hibbits 6256a0ea8f First cut of PowerPC(64) support in LLDB.
Summary:
This adds preliminary support for PowerPC/PowerPC64, for FreeBSD.  There are
some issues still:

 * Breakpoints don't work well on powerpc64.
 * Shared libraries don't yet get loaded for a 32-bit process on powerpc64 host.
 * Backtraces don't work.  This is due to PowerPC ABI using a backchain pointer
   in memory, instead of a dedicated frame pointer register for the backchain.
 * Breakpoints on functions without debug info may not work correctly for 32-bit
   powerpc.

Rely on the UUID match to get the correct file if we have
a UUID -- we'll get no warning if it's a mismatch.

This change does the following:

Enable lldb-gdbserver (llgs) usage for local-process Linux debugging.
To turn on local llgs debugging support, which is disabled by default, enable this setting:

(lldb) settings set platform.plugin.linux.use-llgs-for-local true
Adds a stream-based Dump() function to FileAction.
Pushes some platform methods that Linux (and FreeBSD) will want to share with MacOSX from PlatformDarwin into PlatformPOSIX.

Todd Fiala e15fcaa2e5 Moved PlatformDarwin::GetEnvironment() to PlatformPOSIX to fix Linux/llgs issue.
See http://reviews.llvm.org/D5486 for more details.

I was tracking a problem where llgs on linux would not pick up any environment variables. On OSX there is a virtual function PlatformDarwin::GetEnvironment() which correctly sets up the list of environment variables. On linux llgs it defaults to a base class default implementation which clears the list.

I moved the OSX implementation down to PlatformPOSIX. This fixes my problem on linux still works properly on OSX.

- fix TestImageListMultiArchitecture.py to restore the "host" platform by running "platform select host"

This patch creates a HostInfo class, a static class used to answer

some functionality is moved from Host to HostInfo, and relevant
fixups are performed in the rest of the codebase.

This is part of a larger effort to isolate more code in the Host
layer into platform-specific groups, to make it easier to make
platform specific changes for a particular Host without breaking
other hosts.
