Jonas Devlieghere 73811d32c7 [lldb] Move copying of files into reproducer out of process
For performance reasons the reproducers don't copy the files captured by
the file collector eagerly, but wait until the reproducer needs to be
generated.

This is a problematic when LLDB crashes and we have to do all this
signal-unsafe work in the signal handler. This patch uses a similar
trick to clang, which has the driver invoke a new cc1 instance to do all
this work out-of-process.

This patch moves the writing of the mapping file as well as copying over
the reproducers into a separate process spawned when lldb crashes.

Pavel Labath fa5fa63fd1 [lldb] Port lldb gdb-server to libOption
The existing help text was very terse and was missing several important
options. In the new version, I add a short description of each option
and a slightly longer description of the tool as a whole.

The new option list does not include undocumented no-op options:
--debug and --verbose. It also does not include undocumented short
aliases for long options, with two exceptions: -h, because it's
well-known; and -S (--setsid), as it's used in one test. Using these
options will now produce an error. I believe that is acceptable as users
aren't generally invoking lldb-server directly, and the only way to
learn about the short aliases was by looking at the source.

Jason Molenda 7d67c06391 Remove unused build configurations from debugserver xcode project
the xcode project file for debugserver exists only to make my
life easier when I'm working only on debugserver and don't need
to build the rest of llvm/lldb.  It had many build configurations
to reflect our old lldb xcode project file, which is long gone.
Removing them to simplify the configurations.

Specifically dropping CustomSwift-Debug, DebugClang, DebugPresubmission,
CustomSwift-Release, BuildAndIntegration.  Keeping Debug & Release.

Michał Górny 1a600266c3 [lldb] Initial version of FreeBSD remote process plugin
Add a new FreeBSD Process plugin using client/server model.  This plugin
is based on the one used by NetBSD.  It currently supports a subset
of functionality for amd64.  It is automatically used when spawning
lldb-server.  It can also be used by lldb client by setting
FREEBSD_REMOTE_PLUGIN environment variable (to any value).

The code is capable of debugging simple single-threaded programs.  It
supports general purpose, debug and FPU registers (up to XMM) of amd64,
basic signalling, software breakpoints.

Adding the support for the plugin involves removing some dead code
from FreeBSDPlatform plugin (that was not ever used because
CanDebugProcess() returned false), and replacing it with appropriate
code from NetBSD platform support.

Jordan Rupprecht ad865d9d10 [lldb-vscode] Allow an empty 'breakpoints' field to clear breakpoints.
Per the DAP spec for SetBreakpoints [1], the way to clear breakpoints is: `To clear all breakpoint for a source, specify an empty array.`

However, leaving the breakpoints field unset is also a well formed request (note the `breakpoints?:` in the `SetBreakpointsArguments` definition). If it's unset, we have a couple choices:

1. Crash (current behavior)
2. Clear breakpoints
3. Return an error response that the breakpoints field is missing.

I propose we do (2) instead of (1), and treat an unset breakpoints field the same as an empty breakpoints field.

When running in an ipv6-only environment where `AF_INET` sockets are not available, many lldb tests (mostly gdb remote tests) fail because things like `127.0.0.1` don't work there.

Use `localhost` instead of `127.0.0.1` whenever possible, or include a fallback of creating `AF_INET6` sockets when `AF_INET` fails.

Raphael Isemann f0699d9109 [debugserver] Fix that debugserver's stop reply packets always return signal code 0
If our process terminates due to an unhandled signal, we are supposed to get the
signal code via WTERMSIG. However, we instead try to get the exit status via
WEXITSTATUS which just ends up always calculating signal code 0 (at least on the
macOS implementation where it just shifts the signal code bits away and we're
left with only 0 bits).

The exit status calculation on the LLDB side also seems a bit off as it claims
an exit status that is just the signal code (instead of for example 128 + signal
code), but that will be another patch.

This patch removes the rather confusing LLDB_LIB_DIR and LLDB_IMPLIB_DIR
environment variables. They are confusing because LLDB_LIB_DIR would
point to the bin subdirectory in the build root while LLDB_IMPLIB_DIR

LLDB.framework, which gets build under bin.

This patch replaces their uses with configuration.lldb_framework_path

This patch adds the infrastructure to have language specific REPL init
files. It's the foundation work to a following patch that will introduce
Swift REPL init file.

When lldb is launched with the `--repl` option, it will look for a REPL
init file in the home directory and source it. This overrides the
default `~/.lldbinit`, which content might make the REPL behave
unexpectedly. If the REPL init file doesn't exists, lldb will fall back
to the default init file.

fail) and pass in the temp_file_spec's path as the final path (which is actually

In this diff, the mimeType is a kind of media type for formatting the content in the response to a source request. Elements in the disassembly view, like constants, registers and final line comments are colored for highlighting.
A built-in support in the VSCode IDE for syntax highlighting will identify the which mimeType to apply and render the disassembly view as expected.

Jason Molenda abf546dd4f debguserver's type sniffer to only treat .app things that end in .app
On an iOS device, if debugserver is left to figure out how to launch
the binary provided, it looks at the filename to see if it contains
".app" and asks FrontBoard to launch it.  However, if this is actually
a command line app with the characters ".app" in the name, it would
end up trying to launch that via the FrontBoard calls even though it
needed to be launched via posix_spawn.  For instance, a command line
program called com.application.tester.

Jim suggested this patch where we only send binaries that end in ".app"
to FrontBoard.

Often debugsever is invoked with a --launch command line argument to
specify the launch method, and none of this code is hit in that
instance.
