5cc7de09ef Force SHELL to be cmd.exe on Windows for the test suite
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.

d987a8cf38 Port the Darwin universal binary testcase to x86_64.
Xcode 10 doesn't ship with an i386 SDK any more. This patch ports the
testcase from an i386/x86_64 -> x86_64/x86_64h universal binary.

e103ae92ef Add setting to require hardware breakpoints.
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.

c0e793d654 Work with a gdb-remote target that doesn't handle the
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.

eca07c592a Fix (and improve) the support for C99 variable length array types
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

77198bc79b Remove Go debugger plugin
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.

41ae8e7445 [lldb] Introduce StackFrameRecognizer [take 3]
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

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 artificial tail call frames when this happens. This is only done
when the execution history can be determined from the call graph and
from the return PC addresses of calls on the stack. Ambiguous sequences
of tail calls (e.g anything involving tail calls and recursion) are
detected and ignored.

f796e763b2 DWARFExpression: Resolve file addresses in the linked module
This is a follow-up to https://reviews.llvm.org/D46362.

When evaluating a complex expression in DWARFExpression::Evaluate,
file addresses must be resolved to load addresses before we can
perform operations such as DW_OP_deref on them.

For this the address goes through three steps

1. Read the file address as stored in the DWARF
2. Link/relocate the file address (when reading from a .dSYM, this is a no-op)
3. Convert the file address to a load address.

D46362 implemented step (3) by resolving the file address using the
Module that the original DWARF came from. In the case of a dSYM that
is correct, but when reading from .o files, we need to look up
relocated/linked addresses, so the right place to look them up is the
current frame's module. This patch fixes that by setting the
expression's Module to point to the linked debugmap object.

A word a bout the unorthodox testcase: The motivating testcase for
this fix is in Swift, but I managed to hand-modify LLVM-IR for a
trivial C program to exhibit the same problem, so we can fix this in
llvm.org.

75606b285c [lldbinline] Set directory attribute on test-specific classes
Set the "mydir" attribute of an inline test on the test-specific class,
instead of on the base InlineTest class.

This makes it possible to run dotest.py on a directory containing inline
tests. This wasn't really possible prior to this patch, because what
would happen is that one test would just run over and over again, even
though the test infrastructure would claim that different tests were
being run.

Example:

The test infrastructure claimed that all of these different tests were passing,
which couldn't be true --

$ ./bin/lldb-dotest /Users/vsk/src/tailcall/lldb/test/testcases/functionalities/tail_call_frames/ -G dwarf -t 2>&1 | grep PASS
PASS: LLDB (/Users/vsk/src/builds/tailcall-RA/bin/clang-8-x86_64) :: test_dwarf (lldbsuite.test.lldbtest.TestDisambiguateTailCallSeq)

... because it wasn't even looking at some of these tests:

f853c6e074 [lldbtest] Fix self.filecheck check file lookup
The 'test_filename' property in TestBase changes over time, so
attempting to find a check file relative to the directory containing
'test_filename' is flaky.

Use the absolute path of the check file as that's always correct (and
simpler). This relies on the test driver changing into the test
directory, which it seems we can safely assume.

As a drive-by, make self.filecheck respect the trace (-t) option.

26ba928214 [target] Change target create's behavior wrt loading dependent files.
When creating a target, lldb loads all dependent files (i.e. libs in
LC_LOAD_DYLIB for Mach-O). This can be confusing, especially when two
versions of the same library end up in the shared cache. It's possible
to change this behavior, by specifying  target create -d <target> these
dependents are not loaded.

This patch changes the default behavior to only load dependent files
only when the target is an executable. When creating a target for a
library, it is now no longer necessary to pass -d. The user can still
override this behavior by specifying the -d option to change this
behavior.

7f88829cea Add support for descriptions with command completions.
Summary:
This patch adds a framework for adding descriptions to the command completions we provide.
It also adds descriptions for completed top-level commands so that we can test this code.

Completions are in general supposed to be displayed alongside the completion itself. The descriptions
can be used to provide additional information about the completion to the user. Examples for descriptions
are function signatures when completing function calls in the expression command or the binary name
when providing completion for a symbol.

There is still some boilerplate code from the old completion API left in LLDB (mostly because the respective
APIs are reused for non-completion related purposes, so the CompletionRequest doesn't make sense to be
used), so that's why I still had to change some function signatures. Also, as the old API only passes around a
list of matches, and the descriptions are for these functions just another list, I had to add some code that
essentially just ensures that both lists are always the same side (e.g. all the manual calls to
`descriptions->AddString(X)` below a `matches->AddString(Y)` call).

The initial command descriptions that come with this patch are just reusing the existing
short help that is already added in LLDB.

An example completion with descriptions looks like this:
```
(lldb) pl
Available completions:
        platform -- Commands to manage and create platforms.
        plugin   -- Commands for managing LLDB plugins.
```

bf2d112c15 [DWARFExpression] Read literars as unsigned values.
After landing r341457, we started seeing a failure on the swift-lldb
bots. The change was correct and pretty straightforward, a DW_OP_constu
was replaced with DW_OP_lit23, the value remaining identical.

  0x000000f4: DW_TAG_variable
		DW_AT_location    (0x00000000
		  [0x0000000100000a51,  0x0000000100000d47): DW_OP_lit23, DW_OP_stack_value)
		DW_AT_name        ("number")

However, this broke LLDB.

  (Int) number = <extracting data from value failed>

The value was read correctly, but apparently the value's type was different.
When reading a constu it was reading a uint64 (m_type = e_ulonglong) while for
the literal, it got a signed int (m_type = e_sint). This change makes sure we
read the value as an unsigned.

7482973411 Added initial code completion support for the expr command
Summary:
This patch adds initial code completion support for the `expr` command.

We now have a completion handler in the expression CommandObject that
essentially just attempts to parse the given user expression with Clang with
an attached code completion consumer. We filter and prepare the
code completions provided by Clang and send them back to the completion
API.

The current completion is limited to variables that are in the current scope.
This includes local variables and all types used by local variables. We however
don't do any completion of symbols that are not used in the local scope (or
in some other way already in the ASTContext).

This is partly because there is not yet any code that manually searches for additiona
information in the debug information. Another cause is that for some reason the existing
code for loading these additional symbols when requested by Clang doesn't seem to work.
This will be fixed in a future patch.

207863261c Move the column marking functionality to the Highlighter framework
Summary:
The syntax highlighting feature so far is mutually exclusive with the lldb feature
that marks the current column in the line by underlining it via an ANSI color code.
Meaning that if you enable one, the other is automatically disabled by LLDB.

This was caused by the fact that both features inserted color codes into the the
source code and were likely to interfere with each other (which would result
in a broken source code printout to the user).

This patch moves the cursor code into the highlighting framework, which provides
the same feature to the user in normal non-C source code. For any source code
that is highlighted by Clang, we now also have cursor marking for the whole token
that is under the current source location. E.g., before we underlined only the '!' in the
expression '1 != 2', but now the whole token '!=' is underlined. The same for function
calls and so on. Below you can see two examples where we before only underlined
the first character of the token, but now underline the whole token.

{F7075400}
{F7075414}

It also simplifies the DisplaySourceLines method in the SourceManager as most of
the code in there was essentially just for getting this column marker to work as
a FormatEntity.

do not know how to deal with those types though, so we have to legalize the
size when creating a Scalar.

778b308eb9 Fix broken builtin functions in the expression command
Summary:
Calling any non-libc builtin function in the expression command currently just causes Clang
to state that the function is not known. The reason for this is that we actually never
initialize the list of builtin functions in the Builtin::Context.

This patch just calls the initializer for the builtins in the preprocessor. Also adds some tests
for the new builtins.

It also gets rid of the extra list of builtins in the ClangExpressionParser, as we can just reuse
the existing list in the Preprocessor for the ASTContext. Having just one list of builtins around
is also closer to the standard Clang behavior.
