Summary:
This is part of the Linux remote platform work. Displaying the local
kernel information when remote debugging doesn't make sense, so we
should verify if we are in host mode before doing so.
Test Plan:
Connect to a remote linux platform mode daemon with `platform select
remote-linux` followed by `platform connect ...`, and look at the output
of `platform status`.

in the "dummy-target". The dummy target breakpoints prime all future
targets. Breakpoints set before any target is created (e.g. breakpoints
in ~/.lldbinit) automatically get set in the dummy target. You can also
list, add & delete breakpoints from the dummy target using the "-D" flag,
which is supported by most of the breakpoint commands.
This removes a long-standing wart in lldb...

Fixed include:
- Change Platform::ResolveExecutable(...) to take a ModuleSpec instead of a FileSpec + ArchSpec to help resolve executables correctly when we have just a path + UUID (no arch).
- Add the ability to set the listener in SBLaunchInfo and SBAttachInfo in case you don't want to use the debugger as the default listener.
- 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);

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.

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.

the Arch in the ModuleSpec. If Module::GetObjectFile() sees
that the architecture of the kext is a mismatch for the arch
we're looking for, it'll spew a warning message to the dev (r217251).
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.

See http://reviews.llvm.org/D5695 for details.
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.

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.

- change all callbacks that create platforms to returns shared pointers
- fix TestImageListMultiArchitecture.py to restore the "host" platform by running "platform select host"

This continues the effort to get Host code moved over to HostInfo,
and removes many more instances of preprocessor defines along the
way.
llvm-svn: 216195
This patch creates a HostInfo class, a static class used to answer
basic queries about the host platform. As part of this change,
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.

More specifically, this change can be summarized as follows:
1) Makes an lldbHostPosix library which contains code common to
all posix platforms.
2) Creates Host/FileSystem.h which defines a common FileSystem

3) Implements FileSystem.h in Host/windows and Host/posix.
4) Creates Host/FileCache.h, implemented in Host/common, which
defines a class useful for storing handles to open files needed

AArch64: remove arm64 triple enumerator.
This change fixes build breaks on Linux and MacOSX lldb.
llvm-svn: 213755
This change enables lldb-platform for Linux. In addition, it does the following:
* fixes Host::GetLLDBPath() to work on Linux/*BSD for ePathTypeSupportExecutableDir-relative paths.
* adds more logging and comments around lldb-platform startup and remote lldb-platform usage.
* refactors lldb-platform remote-* support for Darwin and Linux into PlatformPOSIX. This, in theory, is the bulk of what is needed for *BSD to make remote connections to lldb-platform as well (although I haven't tested that yet). FreeBSD can make similar changes to their Platform* as was made here for PlatformLinux to pick up the rest of the bits.
* teaches GDBRemoteCommunication to use lldb-gdbserver for non-Apple hosts.

- Fixed SymbolFileDWARFDebugMap to load .o files correctly by just specifying the architecture without the vendor and OS now that "<arch>-apple-ios" is not compatible with "<arch>-apple-macosx" so we can load .o files correctly for DWARF with debug map
