A couple of new tests have been added that use existing class names. This causes failures on Windows if the tests run at the same time and on any platform it results in the logs being overwritten.

Summary: In order to invoke sed on Windows, we need to quote the command correctly. Since we already have commands which do that, move the definitions at the beginning of the file and then re-use them for each command.

This patch reimplmeents the tests usinf FileCheck, and it also

This saves about 3 redundant gigabytes from the Objective-C test build
directories. Tests that must do unsavory things with the LLDB clang
module cache, already specify a per-test module cache in their .py
test instructions.

Just to be safe, up until now each test used its own Clang module
cache directory. Since the compiler within one testsuite doesn't
change it is just as safe to share a clang module directory inside the
LLDB test build directory. This saves us from compiling tens of
gigabytes of redundant Darwin and Foundation .pcm files and also
speeds up running the test suite quite significantly.

Summary:
Windows make will search for other shells and choose those over cmd
if available (e.g. C:\cygdrive\bin\sh.exe). This shell has numerous
issues with path handling (/ vs \\ vs \ and C:). So default to using
cmd.exe which is known to work.

When debugging read-only memory we cannot use software breakpoint. We
already have support for hardware breakpoints and users can specify them
with `-H`. However, there's no option to force LLDB to use hardware
breakpoints internally, for example while stepping.
This patch adds a setting target.require-hardware-breakpoint that forces
LLDB to always use hardware breakpoints. Because hardware breakpoints
are a limited resource and can fail to resolve, this patch also extends
error handling in thread plans, where breakpoints are used for stepping.

This patch teaches LLDB about more fields on NSException Obj-C objects, specifically we can now retrieve the "name" and "reason" of an NSException. The goal is to eventually be able to have SB API that can provide details about the currently thrown/caught/processed exception.

qWatchpointSupportInfo packet correctly.
In GDBRemoteCommunicationClient::GetWatchpointSupportInfo,
if the response to qWatchpointSupportInfo does not
include the 'num' field, then we did not get an answer
we understood, mark this target as not supporting that
packet.
In Target.cpp, rename the very confusingly named
CheckIfWatchpointsExhausted to CheckIfWatchpointsSupported,
and check the error status returned by
Process::GetWatchpointSupportInfo. If we cannot determine
what the number of supported watchpoints are, assume that
they will work. We'll handle the failure
later when we try to create/enable the watchpoint if the
Z2 packet isn't supported.
Add a gdb_remote_client test case.

Clang recently improved its DWARF support for C VLA types. The DWARF
now looks like this:
0x00000051: DW_TAG_variable [4]
DW_AT_location( fbreg -32 )
DW_AT_name( "__vla_expr" )
DW_AT_type( {0x000000d3} ( long unsigned int ) )
DW_AT_artificial( true )
...
0x000000da: DW_TAG_array_type [10] *
DW_AT_type( {0x000000cc} ( int ) )
0x000000df: DW_TAG_subrange_type [11]
DW_AT_type( {0x000000e9} ( __ARRAY_SIZE_TYPE__ ) )
DW_AT_count( {0x00000051} )
Without this patch LLDB will naively interpret the DIE offset 0x51 as
the static size of the array, which is clearly wrong. This patch
extends ValueObject::GetNumChildren to query the dynamic properties of
incomplete array types.
See the testcase for an example:
4 int foo(int a) {
5 int vla[a];
6 for (int i = 0; i < a; ++i)
7 vla[i] = i;
8
-> 9 pause(); // break here
10 return vla[a-1];
11 }
(lldb) fr v vla
(int []) vla = ([0] = 0, [1] = 1, [2] = 2, [3] = 3)
(lldb) quit

In January Davide sent an e-mail to the mailing list to suggest removing
unmaintained language plugins such as Go and Java. The plan was to have
some cool down period to allow users to speak up, however after that the
plugins were never actually removed.
This patch removes the Go debugger plugin.
The plugin can be added again in the future if it is mature enough both
in terms of testing and maintenance commitment.

This patch introduces a concept of "frame recognizer" and "recognized frame". This should be an extensible mechanism that retrieves information about special frames based on ABI, arguments or other special properties of that frame, even without source code. A few examples where that could be useful could be 1) objc_exception_throw, where we'd like to get the current exception, 2) terminate_with_reason and extracting the current terminate string, 3) recognizing Objective-C frames and automatically extracting the receiver+selector, or perhaps all arguments (based on selector).

Add support in ProcessGDBRemote::GetGDBServerRegisterInfo
for recognizing a generic "arm" architecture that will be used if
nothing better is available so that we don't ignore the register
definitions if we didn't already have an architecture set.
Also in ProcessGDBRemote::DoConnectRemote don't set the target
arch unless we have a valid architecture to set it to.
Platform::ConnectProcess will try to get the current target's
architecture, or the default architecture, when creating the
target for the connection to be attempted. If lldb was started
with a target binary, we want to create this target with that
architecture in case the remote gdb stub doesn't supply a
qHostInfo arch.
Add logging to Target::MergeArchitecture.

This reverts commit r344647.
This causes build failures with [-Werror, -Wswitch]. Some cases where the newly

lldb/source/Expression/REPL.cpp:350
lldb/source/Interpreter/CommandInterpreter.cpp:1529

As I don't understand lldb to make sure the likely trivial fixes are
correct and also as they might need additional tests, leaving to the
author to resolve.

The TestTailCallFrameSBAPI.py test checks that function names in a
backtrace are equal to an expected value.
Use a relaxed substring check because function dislpay names are
platform-dependent. E.g we see "void sink(void)" on Windows, but "sink()" on
Darwin. This seems like a bug -- just work around it for now.
