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
interface.
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
by the debugger.

Fixes include:
1 - added new FileSpec method: bool FileSpec::Readable()
2 - detect when an executable is not readable and give an appropriate error for:
(lldb) file /tmp/unreadablefile
3 - detect when a core file is not readable and give an appropriate error
4 - detect when a specified core file doesn't exist and give an appropriate error

MinGW32 and Cygwin have been removed from the OSType enumeration. They are
represented as environments, and the OS is Windows in both of those cases.
Simply remove the value from the switch.

Change PlatformDarwinKernel::GetKextDirectoriesInSDK
to look in the root directory of places like
/Library/Developer/KDKs/KDK_10.10_14A298i.kdk
as well as the System/Library/Extensions subdir

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.

This change comprises of additions and some minor changes in order that
"kalimba" is listed as a supported platform and that debugging any
kalimbas results in PlatformKalimba being associated with the target.
The changes are as follows:
* The PlatformKalimba implementation itself
* A tweak to ArchSpec
* .note parsing for Kalimba in ObjectFileELF.cpp
* Plugin registration
* Makefile additions

Minor tweak for cmake and Xcode by Todd Fiala
Tested:
Ubuntu 14.04 x86_64, clang 3.5-built lldb, all tests pass.
MacOSX 10.9.4, Xcode 6.0 Beta 1-built lldb, all tests pass.

Fixes include:
- Don't say that "<arch>-apple-ios" is compatible with "<arch>-apple-macosx"
- Fixed DynamicLoaderMacOSXDYLD so specify an architecture that was converted solely from a cputype and subtype, just specify the file + UUID.
- Fixed PlatformiOSSimulator::GetSupportedArchitectureAtIndex() so it returns the correct archs
- 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
- Fixed the coded in TargetList::CreateTarget() so it does the right thing with an underspecified triple where just the arch is specified.

This change brings in lldb-gdbserver (llgs) specifically for Linux x86_64.
(More architectures coming soon).
Not every debugserver option is covered yet. Currently
the lldb-gdbserver command line can start unattached,
start attached to a pid (process-name attach not supported yet),
or accept lldb attaching and launching a process or connecting
by process id.
The history of this large change can be found here:
https://github.com/tfiala/lldb/tree/dev-tfiala-native-protocol-linux-x86_64
Until mid/late April, I was not sharing the work and continued
to rebase it off of head (developed via id tfiala@google.com). I switched over to
user todd.fiala@gmail.com in the middle, and once I went to github, I did
merges rather than rebasing so I could share with others.

Replace adhoc inline implementation of llvm::array_lengthof in favour of the

intended.

process fully reaped. The race & bad behavior was because we were letting
the reaping thread in LLDB to also set the Process exit status, so debugserver
would sometimes be shut down before it got a chance to report the exit status,
and then we got confused.

Changes include:
- ObjectFileMachO can now determine if a binary is "*-apple-ios" or "*-apple-macosx" by checking the min OS and SDK load commands
- ArchSpec now says "<arch>-apple-macosx" is equivalent to "<arch>-apple-ios" since the simulator mixes and matches binaries (some from the system and most from the iOS SDK).
- Getting process inforamtion on MacOSX now correctly classifies iOS simulator processes so they have "*-apple-ios" architectures in the ProcessInstanceInfo
- PlatformiOSSimulator can now list iOS simulator processes correctly instead of showing nothing by using:
(lldb) platform select ios-simulator
(lldb) platform process list
- debugserver can now properly return "*-apple-ios" for the triple in the process info packets for iOS simulator executables
- GDBRemoteCommunicationClient now correctly passes along the triples it gets for process info by setting the OS in the llvm::Triple correctly

These changes were written by Greg Clayton, Jim Ingham, Jason Molenda.
It builds cleanly against TOT llvm with xcodebuild. I updated the
cmake files by visual inspection but did not try a build. I haven't
built these sources on any non-Mac platforms - I don't think this
patch adds any code that requires darwin, but please let me know if
I missed something.
In debugserver, MachProcess.cpp and MachTask.cpp were renamed to
MachProcess.mm and MachTask.mm as they picked up some new Objective-C
code needed to launch processes when running on iOS.

add a new pure virtual CalculateTrapHandlerSymbolNames() that Platform
subclasses must implement which fills in the function name list with any
trap handlers that are expected on that platform.
llvm-svn: 201364
aka asynchronous signal handlers, which subclasses should fill
in as appropriate. For most Unix user process environments,
the one entry in this list is _sigtramp. For bare-board and
kernel environments, there will be different sets of trap
handlers.
The unwinder needs to know when a frame is a trap handler
because the rules it enforces for the frame "above" the
trap handler is different from most middle-of-the-stack frames.

libldi library to collect extended backtrace information; switch

There's still cleanup and documentation to do on this code but the
code is functional and I it's a good time to get the work-in-progress
checked in.

The many many benefits include:
1 - Input/Output/Error streams are now handled as real streams not a push style input
2 - auto completion in python embedded interpreter
3 - multi-line input for "script" and "expression" commands now allow you to edit previous/next lines using up and down arrow keys and this makes multi-line input actually a viable thing to use
4 - it is now possible to use curses to drive LLDB (please try the "gui" command)
We will need to deal with and fix any buildbot failures and tests and arise now that input/output and error are correctly hooked up in all cases.

This rename was suggested by gclayton as a way to silence gcc
warnings; the warning is emitted when there is an overloaded function
in a base class (Platform) for which a derived class redefines one of
the overloads but not the other (because doing so hides the other
overload from users of the derived class). By giving the two methods
different names, the situation is avoided.
