Also fixed the host 32 and 64 bit arch to return "x86_64-apple-macosx" again instead of "x86_64-apple-" (unspecified OS) after recent changes.

library, which already provides a cross-platform implementation
of this function.

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.

reinterpret_cast may not convert a pointer-to-function to a

pointer-to-function.
This silences a warning emitted by GCC when building LLDB.

lldb -P, which outputs its python path, works by using Host-layer
facilities to get information about the loaded python module. This
Host functionality was unimplemented on Windows, so this patch
implements it. Additionally, it removes a pexpect dependency from
the test runner and uses an equivalent invocation of subprocess.

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.

This patch implements basic functionality of the "platform process
list" command for Windows. Currently this has the following
limitations.
* Certain types of filtering are not enabled (e.g. filtering by
architecture with -a), although most filters work.
* The username of the process is not yet obtained.
* Using -v to list verbose information generates an error.
* The architecture column displays the entire triple, leading to
misaligned formatting of the printed table.

It builds cleanly against TOT llvm with xcodebuild. I updated the

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.

(lldb) b puts
(lldb) expr -g -i0 -- (int)puts("hello")
First we will stop at the entry point of the expression before it runs, then we can step over a few times and hit the breakpoint in "puts", then we can continue and finishing stepping and fininsh the expression.
Main features:
- New ObjectFileJIT class that can be easily created for JIT functions
- debug info can now be enabled when parsing expressions
- source for any function that is run throught the JIT is now saved in LLDB process specific temp directory and cleaned up on exit
- "expr -g --" allows you to single step through your expression function with source code

This reverts Host.cpp LaunchProcess spawn behavior on FreeBSD to be
like Linux (and unlike OS X) with regards to how default signal
handlers and setup on the spawned process. FreeBSD does not reset
default signal handlers on the spawned process after this change.
llvm-svn: 199908
This fixes a bug under Linux where spawning a process via
Host::LaunchProcess was disabling all blockable signals on the
launched process. This caused strange behavior when attempting
to kill the lldb-gdbserver process, as the child generally would
not die unless killed with a non-blockable signal (e.g. 'kill -9').
This change moves several functions out of macosx/Host.mm into
common/Host.cpp. In addition, two functions that needed to work
across common/Host.cpp and macosx/Host.mm were moved into the Host.h
header file.

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
lowercased, and whitespace is replaced with underscores.
llvm-svn: 199539
The Linux distribution will be added to the ArchSpec class in an
upcoming change. This change only undoes the change to the triple. The
distribution retrieval logic and enabling of lldb-gdbserver for linux
x86_64 builds is still in place.
llvm-svn: 199520
This change does the following:
* enables building lldb-gdbserver on linux_x86-64 platforms.
Note - it builds but it has several run-time issues where many gdb
remote protocol features are not properly implemented yet. I'm
working on these one at a time.
* lldb-gdbserver: does not enable the eLaunchFlagDebug launch flag on
Linux. Currently the POSIX launch routine will assert if that flag
is passed in, presumably because that launch mode is not yet
available. This prevents lldb-gdbserver from asserting the moment
it launches the debuggee process.
* Adds ConstString& Host::GetDistributionId ()
This method is defined to return an empty result on all platforms
except for Linux. On Linux, it makes one attempt to execute
'lsb_release -i' (both /usr/bin/lsb_release, where it appears
on ubuntu, and /bin/lsb_release, where it appears on fedora
if the redhat-lsb package is installed). If lsb_release is not
found in either of those locations, or if 'lsb_release -i' does
not return the first line starting with "Distributor ID:\t",
then the distribution id is empty. The method will lower-case
the id and replace whitespace with underscores.
* Modify Host::GetArchitecture () so that linux replaces an unknown
vendor portion with the results of GetDistributionId () if that
is non-empty. This shows up now in qHostInfo remote packet
responses and on the lldb host side. Tested with ubuntu and
fedora (the latter both with the default of not having lsb_release
installed, and with having lsb_release installed via the redhat-lsb
package).
Examples of triples on Linux after this change:
# x86_64 Unbuntu 12.04 LTS:
x86_64-ubuntu-linux-gnu
# x86_64 Fedora 20 Desktop with redhat-lsb package installed
x86_64-fedora-linux-gnu
# x86_64 Fedora 20 Desktop without redhat-lsb-core installed
# (i.e. no /bin/lsb_release available)
# same as before the change
x86_64--linux-gnu
Note I intend to have Android respond with:
{arch}-android-linux
when I get to implementing Android lldb-gdbserver support.

Improved the detection of a valid GDB server where we actually can connect to a socket, but then it doesn't read or write anything (which happens with some USB mux software).
Host::MakeDirectory() now can make as many intermediate directories as needed.
The testsuite now has very initial support for remote test suite running. When running on a remote platform, the setUp function for the test will make a new directory and select it as the working directory on the remote host.
Added a common function that can be used to create the short option string for getopt_long calls.

Example code:
remote_platform = lldb.SBPlatform("remote-macosx");
remote_platform.SetWorkingDirectory("/private/tmp")
debugger.SetSelectedPlatform(remote_platform)
connect_options = lldb.SBPlatformConnectOptions("connect://localhost:1111");
err = remote_platform.ConnectRemote(connect_options)
if err.Success():
print >> result, 'Connected to remote platform:'
print >> result, 'hostname: %s' % (remote_platform.GetHostname())
src = lldb.SBFileSpec("/Applications/Xcode.app/Contents/SharedFrameworks/LLDB.framework", False)
dst = lldb.SBFileSpec()
# copy src to platform working directory since "dst" is empty
err = remote_platform.Install(src, dst);
if err.Success():
print >> result, '%s installed successfully' % (src)
else:
print >> result, 'error: failed to install "%s": %s' % (src, err)
Implemented many calls needed in lldb-platform to be able to install a directory that contains symlinks, file and directories.
The remote lldb-platform can now launch GDB servers on the remote system so that remote debugging can be spawned through the remote platform when connected to a remote platform.
The API in SBPlatform is subject to change and will be getting many new functions.
