Currently, `SBCommandInterpreterRunOptions` is defined in
`SBCommandInterpreter.h`. Given that the options are always passed by
reference, a forward declaration is sufficient.
That's not the case for `SBCommandInterpreterRunResults`, which we need
for a new overload for `RunCommandInterpreter` and that returns this new
class by value. We can't include `SBCommandInterpreter.h` because
`SBCommandInterpreter::GetDebugger()` returns SBDebugger by value and
therefore needs a full definition.
This patch moves the definition of `SBCommandInterpreterRunOptions` into
a new header. In a later patch, `SBCommandInterpreterRunResults` will
be defined in there as well, solving the aforementioned problem.

This implements Greg's suggestion from D78825 to include "auto handle
events" and "spawn thread" in CommandInterpreterRunOptions. This change
is in preparation for adding a new overload for RunCommandInterpreter
that takes only SBCommandInterpreterRunOptions and returns
SBCommandInterpreterRunResults.

It seems like only the unittests are building with
BUILD_WITH_INSTALL_RPATH set to OFF. Of course when I did my last change
I only ran check-lldb-unit. Not sure why this difference exists, why
would you even install the unittest?
For the LLDB framework we do need different build and install RPATHs.
Currently that logic lives downstream. I plan to upstream that in the
near future. For now I'm just trying to make it possible to run the
test.
Summary:
This was originally commented out as it broke the data-formatter-stl/libcxx/
tests. However this was fixed by commit ef423a3ba5
(Add Objective-C property accessors loaded from Clang module DWARF to lookup)
which sets the HasExternalVisibleStorage flag for the template specializations.

The install name for the Python 3 framework in Xcode is relative to
the framework's location and not the dylib itself.
@rpath/Python3.framework/Versions/3.x/Python3
This means that we need to compute the path to the Python3.framework
and use that as the RPATH instead of the usual dylib's directory.
The cause of this crash is relatively simple -- we are using a
SymbolFileDWARFDwo to parse a (skeleton) dwarf unit. This cause the
CompileUnit to be created with the wrong ID, which later triggers an
assertion in SymbolFile::SetCompileUnitAtIndex. The fix is also simple
-- ensure we use the right symbol file for parsing.
However, a fairly elaborate setup is needed trigger this bug, because
ParseCompileUnit is normally called very early on (and with the right
symbol file object) during the process of accessing a compile unit.
The only way this can be triggered is if the DWARF unit is
"accidentally" pulled into scope during expression evaluation
This can happen if the "this" object used for the context of an
expression is in a namespace, and that namespace is also present in
other compile units
The included test recreates this setup.

Nothing guarantees that the objects in the StringMap remains at the same
address when the StringMap grows. Therefore we shouldn't return a
reference into the StringMap but return a copy of the string instead.
Summary:
Currently loading core files on lldb-vscode is broken because there's a check in the attach workflow that asserts that the PID is valid, which of course fails for this case.
Hence, I'm adding a "coreFile" argument for the attach request, which does the work correctly.
I don't know how to test it effectively so that it runs on the buildbots and the debugger can in fact makes sense of it. Anyway, the change has been relatively simple.

to make the code conform to llvm style better:
- avoid use of auto where the type is not obivous
- avoid StringRef::data where it is not needed
No functional change intended.
This method has been commented as deprecated for a while. Remove
it and replace all uses with the equivalent getCalledOperand().
I also made a few cleanups in here. For example, to removes use
of getElementType on a pointer when we could just use getFunctionType

This patch improves data formatting for CoreFoundation containers:
CFDictionary and CFSet.
These data formatters make the containers and their children appear in Xcode's
variables view (and on the command line) without having to expand the
data structure.
Previous implementation only supported showing the container's element count.
```
(lldb) frame var dict
(__NSCFDictionary *) dict = 0x00000001004062b0 2 key/value pairs
(lldb) frame var set
(__NSCFSet *) set = 0x0000000100406330 2 elements
```
Now the variable can be dereferenced to dispaly the container's children:
```
(lldb) frame var *dict
(__NSCFDictionary) *dict = {
[0] = {
key = 0x0000000100004050 @"123"
value = 0x0000000100004090 @"456"
}
[1] = {
key = 0x0000000100004030 @"abc"
value = 0x0000000100004070 @"def"
}
}
(lldb) frame var *set
(__NSCFSet) *set = {
[0] = 0x0000000100004050 @"123"
[1] = 0x0000000100004030 @"abc"

Sadly IPv6 is still not present anywhere. The test was attempting to
detect&skip such hosts, but the way it did that (essentially, by calling
getaddrinfo) meant that it only detected hosts which have IPv6 support
completely compiled out. It did not do anything about hosts which have
it compiled in, but lack runtime configuration even for the ::1 loopback
address.
This patch changes the detection logic to use a new method. It does it
by attempting to bind a socket to the appropriate loopback address. That
should ensure the hosts loopback interface is fully set up. In an effort
to avoid silently skipping the test on too many hosts, the test is
fairly strict about the kind of error it expects in these cases -- it
will only skip the test when receiving EADDRNOTAVAIL. If we find other
error codes that can be reasonably returned in these situations, we can
add more of them.
The (small) change in TCPSocket.cpp is to ensure that the code correctly
propagates the error received from the OS.
this is dead and non-functional code that hasn't been touched (modulo
refactors) since it was checked in (as an "NFC, with no review and
tests) in 2016.
Anyone interested in adding darwin support to lldb-server can look this
up in git history.

I don't know why the test program is failing and I couldn't reproduce this problem on my own.
This patch is a stab in the dark that just tries to make the test code more similar to code which
we would expect in a user program to make whatever part of macOS happy that is currently
not liking our code.
The actual changes are:
* We pass in argv[0] that is describing otherprog path instead of the current argv[0].
* We pass in a non-null envp (which anyway doesn't seem to be allowed on macOS man page).

Summary:
Currently the breakpoint command is prompting the user to file a bug report if the provided regex is invalid:
```
(lldb) rbreak *foo
error: Function name regular expression could not be compiled: "Inconvertible error value. An error has occurred that could not be converted to a known std::error_code. Please file a bug. repetition-operator operand invalid"
```
The reason is simply that we are using the wrong StringError constructor (the one with the error code as the first parameter
is also printing the string version of the error code, and the inconvertible error code is just an invalid place holder code with
that description). Switching the StringError constructor parameters will only print the error message we get from the regex
engine when we convert the error into a string.
I checked the rest of the code base and I couldn't find the same issue anywhere else.

Summary:
The code in DWARFCompileUnit::BuildAddressRangeTable tries hard to avoid
relying on DW_AT_low/high_pc for compile unit range information, and
this logic is a big cause of llvm/lldb divergence in the lowest layers
of dwarf parsing code.
The implicit assumption in that code is that this information (as opposed to
DW_AT_ranges) is unreliable. However, I have not been able to verify
that assumption. It is definitely not true for all present-day
compilers (gcc, clang, icc), and it was also not the case for the
historic compilers that I have been able to get a hold of (thanks Matt
Godbolt).
All compiler included in my research either produced correct
DW_AT_ranges or .debug_aranges entries, or they produced no DW_AT_hi/lo
pc at all. The detailed findings are:
- gcc >= 4.4: produces DW_AT_ranges and .debug_aranges
- 4.1 <= gcc < 4.4: no DW_AT_ranges, no DW_AT_high_pc, .debug_aranges
present. The upper version range here is uncertain as godbolt.org does
not have intermediate versions.
- gcc < 4.1: no versions on godbolt.org
- clang >= 3.5: produces DW_AT_ranges, and (optionally) .debug_aranges
- 3.4 <= clang < 3.5: no DW_AT_ranges, no DW_AT_high_pc, .debug_aranges
present.
- clang <= 3.3: no DW_AT_ranges, no DW_AT_high_pc, no .debug_aranges
- icc >= 16.0.1: produces DW_AT_ranges
- icc < 16.0.1: no functional versions on godbolt.org (some are present
but fail to compile)
Based on this analysis, I believe it is safe to start trusting
DW_AT_low/high_pc information in dwarf as well as remove the code for
manually reconstructing range information by traversing the DIE
structure, and just keep the line table fallback. The only compilers
where this will change behavior are pre-3.4 clangs, which are almost 7
years old now. However, the functionality should remain unchanged
because we will be able to reconstruct this information from the line
table, which seems to be needed for some line-tables-only scenarios
anyway (haven't researched this too much, but at least some compilers
seem to emit DW_AT_ranges even in these situations).
In addition, benchmarks showed that for these compilers computing the
ranges via line tables is noticably faster than doing so via the DIE
tree.
Other advantages include simplifying the code base, removing some
untested code (the only test changes are recent tests with overly
reduced synthetic dwarf), and increasing llvm convergence.
