Krasimir Georgiev a35912da9f Revert "Return a named error in the result object of an expression with no result"
This reverts commit r344647.
This causes build failures with [-Werror, -Wswitch]. Some cases where the newly
introduced enum value is not handled in particular are in:
  lldb/source/Expression/REPL.cpp:350
  lldb/source/Interpreter/CommandInterpreter.cpp:1529
(maybe there could be more)

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.

Jim Ingham b1ecc3cac2 Return a named error in the result object of an expression with no result
Before we returned an error that was not exposed in the SB API and no useful
error message.  This change returns eExpressionProducedNoResult and an
appropriate error string.

Pavel Labath d821c997aa Move RegisterValue,Scalar,State from Core to Utility
These three classes have no external dependencies, but they are used
from various low-level APIs. Moving them down to Utility improves
overall code layering (although it still does not break any particular
dependency completely).

The XCode project will need to be updated after this change.

Jonas Devlieghere 937348cd13 [FileSpec] Make style argument mandatory for SetFile. NFC
SetFile has an optional style argument which defaulted to the native
style. This patch makes that argument mandatory so clients of the
FileSpec class are forced to think about the correct syntax.

At the same time this introduces a (protected) convenience method to
update the file from within the FileSpec class that keeps the current
style.

These two changes together prevent a potential pitfall where the style
might be forgotten, leading to the path being updated and the style
unintentionally being changed to the host style.

Pavel Labath 145d95c964 Move Args.cpp from Interpreter to Utility
Summary:
The Args class is used in plenty of places besides the command
interpreter (e.g., anything requiring an argc+argv combo, such as when
launching a process), so it needs to be in a lower layer. Now that the
class has no external dependencies, it can be moved down to the Utility
module.

This removes the last (direct) dependency from the Host module to
Interpreter, so I remove the Interpreter module from Host's dependency
list.

Jim Ingham b842f2ecf0 Make breakpoint names real entities.
When introduced, breakpoint names were just tags that you could
apply to breakpoints that would allow you to refer to a breakpoint
when you couldn't capture the ID, or to refer to a collection of
breakpoints.  

This change makes the names independent holders of breakpoint options
that you can then apply to breakpoints when you add the name to the
breakpoint.  It adds the "breakpoint name configure" command to set
up or reconfigure breakpoint names.  There is also full support for
then in the SB API, including a new SBBreakpointName class.

The connection between the name and the breakpoints
sharing the name remains live, so if you reconfigure the name, all the
breakpoint options all change as well.  This allows a quick way
to share complex breakpoint behavior among a bunch of breakpoints, and
a convenient way to iterate on the set.

You can also create a name from a breakpoint, allowing a quick way
to copy options from one breakpoint to another.

I also added the ability to make hidden and delete/disable protected
names.  When applied to a breakpoint, you will only be able to list,
delete or disable that breakpoint if you refer to it explicitly by ID.

This feature will allow GUI's that need to use breakpoints for their
own purposes to keep their breakpoints from getting accidentally 
disabled or deleted.

This renames the LLDB error class to Status, as discussed
on the lldb-dev mailing list.

A change of this magnitude cannot easily be done without
find and replace, but that has potential to catch unwanted
occurrences of common strings such as "Error".  Every effort
was made to find all the obvious things such as the word "Error"
appearing in a string, etc, but it's possible there are still
some lingering occurences left around.  Hopefully nothing too

methods.  These methods see the low-level context representation.
However, the runtime calls APIs that require the high-level context
representation.  Therefore, it needs to call yet another API to find
the high-level representation associated with a given low-level
representation.

Zachary Turner 7f6a7a3752 Remove FileSpec::ReadFileContents.
This functionality is subsumed by DataBufferLLVM, which is
also more efficient since it will try to mmap.  However, we
don't yet support mmaping writable private sections, and in
some cases we were using ReadFileContents and then modifying
the buffer.  To address that I've added a flag to the
DataBufferLLVM methods that allow you to map privately, which
disables the mmaping path entirely.  Eventually we should teach
DataBufferLLVM to use mmap with writable private, but that is
orthogonal to this effort.

Pavel Labath 6302bf6a26 Clean up debug logging
Summary:
We've had two ways to print a "debug" log message.
- Log::GetDebug() was testing a Stream flag which was never set.
- Log::Debug() was checking for the presence of "log enable --debug"
flag.

Given that these two were used very rarely and we already have a
different way to specify "I want a more verbose log", I propose to remove
these two functions and migrate the callers to LLDB_LOGV. This commit
does that.

Zachary Turner bf9a77305f Move classes from Core -> Utility.
This moves the following classes from Core -> Utility.

ConstString
Error
RegularExpression
Stream
StreamString

The goal here is to get lldbUtility into a state where it has
no dependendencies except on itself and LLVM, so it can be the
starting point at which to start untangling LLDB's dependencies.
These are all low level and very widely used classes, and
previously lldbUtility had dependencies up to lldbCore in order
to use these classes.  So moving then down to lldbUtility makes
sense from both the short term and long term perspective in
solving this problem.

Luke Drummond 81fc84fa07 [RenderScript] Fix reduction argument printing
When placing function name breakpoints on RenderScript Reduction kernel
functions, we were not skipping over the function prologue meaning that
inspection of the arguments could be garbled as the function was not finished
setting up the stack/registers.

In
[122fe8f](122fe8f472)
Aidan added the `SkipPrologue` function that allows us to trivially fix up the
kernel's functions' resolved addresses, falling gracefully back to the old
behaviour if we don't know how to handle the prologue or can't resolve its
size.

- Add new `lldb_private::lldb_renderscript::RSReduceBreakpointResolver`
class that can set breakpoints on kernels that are constituent
functions of named reduction groups. Also support debugging of subsets
of the the reduction group with the `-t, --function-role` flag which
takes a comma-separated list of reduction function types
outconverter,combiner,initializer,accumulator (defaults to all)

- Add 2 new helper methods to `RenderScriptRuntime`,
  1. `CreateReductionBreakpoint(name, types)`: instantiates a new
  RSReduceBreakpointResolver and inserts that resolver into the running
  process.
  2. `PlaceBreakpointOnReduction`: which is a public helper function.

- hook up the above functionality to the command-line with new
  `CommandObject*` classes that handle parsing of function roles and
  dispatch to the runtime. These are namespaced under the snappy
  `language renderscript reduction breakpoint ...` subcommand

- [incidental] Factor multiple common uses of

  `IsRenderScriptScriptModule(ModuleSP module)` function, and replace

Luke Drummond 00f56eebcd cleanup RSCoordinate handling and factor out coordinate parser
- This change updates the signature of
`RenderScriptRuntime::PlaceBreakpointOnKernel` to take a default
RSCoordinate pointer of nullptr. We use this as the predicate value for
the breakpoint coordinate rather than trying to fit a sentinel `-1` into
a signed version.

```
- void
- PlaceBreakpointOnKernel(Stream &strm, const char *name, const std::array<int, 3> coords, Error &error,
- lldb::TargetSP target);
```

```
+ bool
+ PlaceBreakpointOnKernel(lldb::TargetSP target, Stream &messages, const char *name,
+ const lldb_renderscript::RSCoordinate *coords = nullptr);
```
The above change makes the API for setting breakpoints on kernels
cleaner as it returns a failure value rather than modify a sentinel in
the caller. The optional arguments are now last and have a default
(falsey) value.

- RSCoordinate objects are now comparable with operator== and have
  zero initializers which should make them easier to work on.
- Added a `FMT_COORD` macro for use in logging format strings which
  should make format strings a little less verbose.

Zachary Turner 1f0f5b5b9e Convert option tables to ArrayRefs.
This change is very mechanical.  All it does is change the
signature of `Options::GetDefinitions()` and `OptionGroup::
GetDefinitions()` to return an `ArrayRef<OptionDefinition>`
instead of a `const OptionDefinition *`.  In the case of the
former, it deletes the sentinel entry from every table, and
in the case of the latter, it removes the `GetNumDefinitions()`
method from the interface.  These are no longer necessary as
`ArrayRef` carries its own length.

In the former case, iteration was done by using a sentinel
entry, so there was no knowledge of length.  Because of this
the individual option tables were allowed to be defined below
the corresponding class (after all, only a pointer was needed).
Now, however, the length must be known at compile time to
construct the `ArrayRef`, and as a result it is necessary to
move every option table before its corresponding class.  This
results in this CL looking very big, but in terms of substance
there is not much here.

Luke Drummond 7f193d6903 [RenderScript] Support tracking and dumping reduction kernels
Initial implementation of support for tracking
[RenderScript Reductions](https://developer.android.com/guide/topics/renderscript/compute.html#reduction-in-depth)

With this patch, `language renderscript module dump` properly lists reductions
that are part of loaded RenderScript modules as well the the consituent
functions and their roles, within the reduction.

This support required new tracking mechanisms for the `#pragma(reduce)`
mechanism, and extension of `RSModuleDescriptor::ParseRSInfo` to support
the metadata output by `bcc`. This work was also an opportunity to
refactor/improve parse code:

- `RSModuleDescriptor::ParseExportReduceCount` now has a complete
  implementation and the debugger can correctly track reductions on
  receipt of a module hook.
- `RSModuleDescriptor::Dump` now dumps Reductions as well as `ForEach`
  kernels. Also, fixed indentation of the output, and made indentation
  groupings in the source clearer.
- `RSModuleDescriptor::ParseRSInfo` now returns true if the `".rs.info"`
  packet has nonzero linecount, rather than rejecting RenderScripts that
  don't contain kernels (an unlikely situation, but possibly valid). This
  was changed because scripts that only contained reductions were not
  being tracked in `RenderScriptRuntime::LoadModule`.
- Refactor `RSModuleInfo::ParseRSInfo` and add reduction spec parser stub
 - Prepared ParseRSInfo to more easily be able to add new parser types
 - Use llvm::StringRef and llvm::StringMap helpers to make the parsing code cleaner
 - factor out forEachCount, globalVarCount, and pragmaCount parsing block to their own methods
 - Add ExportReduceCount Parser
 - Use `llvm::StringRef` in `RSKernelDescriptor` constructor
 - removed now superfluous `MAXLINE` macros as we've switched from `const
   char *` to `llvm::StringRef`

Firstly, merging this particular commit into a downstream fork may be a huge

performing the same reformatting operation locally, and then discarding the

The version of clang-format used was 3.9.0, and autopep8 was 1.2.4.

Luke Drummond 19459580af Add IR fixups for RenderScript ABI mismatch between ARMV7 frontend and x86 backend
Expression evaluation for function calls to certain public RenderScript
API functions in libRSCPURef can segfault.

`slang`,
the compiler frontend for RenderScript embeds an ARM specific triple in
IR that is shipped in the app, after generating IR that has some
assumptions that an ARM device is the target.
As the IR is then compiled on a device of unknown (at time the IR was
generated at least) architecture, when calling RenderScript API function
as part of debugger expressions, we have to perform a fixup pass that
removes those assumptions right before the module is sent to be
generated by the llvm backend.

This issue is caused by multiple problems with the ARMv7-specific
assumptions encoded in the LLVM IR. x86 large value returns use a hidden
first argument (mapping to llvm::Attribute::StructRet), which can't be
picked up by the JIT due to the mismatch between IR generated by the
slang frontend and llvm backend. This means that code generated by bcc
did not necessarily match the default SysV Linux/Android ABI used by the
LLDB JIT

Aidan Dodds 8433fdbedf [Renderscript] Explicitly set the language to evaluate allocations
Currently it is not specified, and since allocations are usually
requested once we hit a renderscript breakpoint, the language will be
inferred being as renderscript by the ExpressionParser.
Actually allocations attempt to invoke functions part of the RS runtime,
written in C/C++, so evaluating the calls in RenderScript could be
misleading.

In particular, in MIPS, the ABI between C/C++ (mips o32) and
renderscript (arm) might introduce subtle bugs when evaluating such
expressions.

This change explicitly sets the language used to evaluate the allocations
as C++.

Enrico Granata 0b6003f3e6 Make LanguageRuntime::GetDynamicTypeAndAddress return a ValueType
For C++ and ObjC, dynamic values are always (at least somewhat) pointer-like in nature, so a ValueType of scalar is actually good enough that it could originally be hardcoded as the right choice
Other languages, might have broader notions of things that are dynamic (e.g. a language where a value type can be dynamic). In those cases, it might actually be the case that a dynamic value is a pointer-to the data, or even a host address if dynamic expression results entirely in host space are being talked about

Greg Clayton 358cf1ea30 Resubmitting 240466 after fixing the linux test suite failures.
A few extras were fixed

- Symbol::GetAddress() now returns an Address object, not a reference. There were places where people were accessing the address of a symbol when the symbol's value wasn't an address symbol. On MacOSX, undefined symbols have a value zero and some places where using the symbol's address and getting an absolute address of zero (since an Address object with no section and an m_offset whose value isn't LLDB_INVALID_ADDRESS is considered an absolute address). So fixing this required some changes to make sure people were getting what they expected. 
- Since some places want to access the address as a reference, I added a few new functions to symbol:
    Address &Symbol::GetAddressRef();
    const Address &Symbol::GetAddressRef() const;

Linux test suite passes just fine now.
