Zachary Turner cb37ddda0d Remove some unnecessary headers from Host.cpp
After the recent migration of code out of Host.cpp, many
unnecessary headers were still being included.  This prunes the
include list down to only what is still necessary.

Zachary Turner 172d37d3b9 Create a process launcher abstraction.
This implements Host::LaunchProcess for windows, and in doing so
does some minor refactor to move towards a more modular process
launching design.

The original motivation for this is that launching processes on
windows needs some very windows specific code, which would live
most appropriately in source/Host/windows somewhere.  However,
there is already some common code that all platforms use when
launching a process before delegating to the platform specific
stuff, which lives in source/Host/common/Host.cpp which would
be nice to reuse without duplicating.

This commonality has been abstracted into MonitoringProcessLauncher,
a class which abstracts out the notion of launching a process using
an arbitrary algorithm, and then monitoring it for state changes.

The windows specific launching code lives in ProcessLauncherWindows,
and the posix specific launching code lives in ProcessLauncherPosix.
When launching a process MonitoringProcessLauncher is created, and
then an appropriate delegate launcher is created and given to the
MonitoringProcessLauncher.

Todd Fiala cacde7df6d Enable llgs to build against experimental Android AOSP lldb/llvm/clang/compiler-rt repos.

Greg Clayton 615eb7e609 Test suite runs better again after recent fixes that would select a platform if a "file a.out" auto selected a different platform than the selected one.
Changes include:
- fix it so you can select the "host" platform using "platform select host"
- change all callbacks that create platforms to returns shared pointers
- fix TestImageListMultiArchitecture.py to restore the "host" platform by running "platform select host"
- Add a new "PlatformSP Platform::Find(const ConstString &name)" method to get a cached platform
- cache platforms that are created and re-use them instead of always creating a new one

Todd Fiala 4ceced3f59 Consolidate UnixSignals setting/getting in Process.
See http://reviews.llvm.org/D5108 for details.

This change does the following:

* eliminates the Process::GetUnixSignals() virtual method and replaces with a fixed getter.
* replaces the Process UnixSignals storage with a shared pointer.
* adds a Process constructor variant that can be passed the UnixSignalsSP. When the constructor without the UnixSignalsSP is specified, the Host's default UnixSignals is used.
* adds a host-specific version of GetUnixSignals() that is used when we need the host's appropriate UnixSignals variant.
* replaces GetUnixSignals() overrides in PlatformElfCore, ProcessGDBRemote, ProcessFreeBSD and ProcessLinux with code that appropriately sets the Process::UnixSignals for the process.

This change also enables some future patches that will enable llgs to be used for local Linux debugging.

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

FileAction was previously a nested class in ProcessLaunchInfo.
This led to some unfortunate style consequences, such as requiring

makes FileAction its own independent class in the Target layer,
and then moves AddPosixSpawnFileAction() into Host as a result.

Todd Fiala 015d818b59 Enable lldb-platform exe support for Linux.
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.

Todd Fiala 17096d7669 Add Host::MAX_THREAD_NAME_LENGTH constant.
This value gets set to a max uint32_t value when there is no known limit; otherwise,
it is set to a value appropriate for the platform.  For the moment, only
Linux, FreeBSD and NetBSD set it to 16.  All other platforms set it to
the max uint32_t value.

Modifies the Process private state thread names to fit within a 16-character limit
when the max thread name length is <= 16.  These guarantee that the thread names
can be distinguished within the first 16 characters.  Prior to this change, those
threads had names in the final dotted name segment that were not distinguishable
within the first 16 characters.

- source for any function that is run throught the JIT is now saved in LLDB process specific temp directory and cleaned up on exit

Todd Fiala a9ddb0e14f Added distribution info to ArchSpec and qHostInfo message.
ArchSpec now contains an optional distribution_id, with getters and
setters. Host::GetArchitecture () sets it on non-Apple platforms using
Host::GetDistributionId (). The distribution_id is ignored during
ArchSpec comparisons.

The gdb remote qHostInfo message transmits it, if set, via the
distribution_id={id-value} key/value pair. Updated gdb remote docs to
reflect this change.

As before, GetDistributionId () returns nothing on non-Linux platforms
at this time. On Linux, it is returned only if the lsb_platform
command is installed (in /bin or /usr/bin), and only if the
distributor id key is returned by 'lsb_platform -i'. This id is
