This patch updates a bunch of places where add_dependencies was being explicitly called to add dependencies on intrinsics_gen to instead use the DEPENDS named parameter. This cleanup is needed for a patch I'm working on to add a dependency debugging mode to the build system.

Zachary Turner c156427ded Don't allow direct access to StreamString's internal buffer.
This is a large API change that removes the two functions from
StreamString that return a std::string& and a const std::string&,
and instead provide one function which returns a StringRef.

Direct access to the underlying buffer violates the concept of
a "stream" which is intended to provide forward only access,
and makes porting to llvm::raw_ostream more difficult in the
future.

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.

Zachary Turner 97d2c4011b Convert some Args index-based iteration to range-style iteration.
This is better for a number of reasons.  Mostly style, but also:

1) Signed-unsigned comparison warnings disappear since there is
   no loop index.
2) Iterating with the range-for style gives you back an entry
   that has more than just a const char*, so it's more efficient
   and more useful.
3) Makes code safter since the type system enforces that it's
   impossible to index out of bounds.

Luke Drummond b3bbcb1229 Add the ability to set breakpoints on named RenderScript reductions
- 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
  `FindFirstSymbolWithNameAndType(ConstString(".rs.info")` into static
  `IsRenderScriptScriptModule(ModuleSP module)` function, and replace
  original uses.

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`

Kate Stone b9c1b51e45 *** This commit represents a complete reformatting of the LLDB source code
*** to conform to clang-format’s LLVM style.  This kind of mass change has
*** two obvious implications:

Firstly, merging this particular commit into a downstream fork may be a huge
effort.  Alternatively, it may be worth merging all changes up to this commit,
performing the same reformatting operation locally, and then discarding the
merge for this particular commit.  The commands used to accomplish this
reformatting were as follows (with current working directory as the root of
the repository):

    find . \( -iname "*.c" -or -iname "*.cpp" -or -iname "*.h" -or -iname "*.mm" \) -exec clang-format -i {} +
    find . -iname "*.py" -exec autopep8 --in-place --aggressive --aggressive {} + ;

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

Secondly, “blame” style tools will generally point to this commit instead of
a meaningful prior commit.  There are alternatives available that will attempt
to look through this change and find the appropriate prior commit.  YMMV.

Zachary Turner f343968f5d Delete Host/windows/win32.h
It's always hard to remember when to include this file, and
when you do include it it's hard to remember what preprocessor
check it needs to be behind, and then you further have to remember
whether it's windows.h or win32.h which you need to include.

This patch changes the name to PosixApi.h, which is more appropriately
named, and makes it independent of any preprocessor setting.

There's still the issue of people not knowing when to include this,
because there's not a well-defined set of things it exposes other
than "whatever is missing on Windows", but at least this should
make it less painful to fix when problems arise.

This patch depends on LLVM revision r278170.

Luke Drummond 5d05763761 [RenderScript] Always create a new allocation ID in CaptureAllocationInit hook
Due to internal reuse of buffers in the RenderScript runtime by the system allocator,
comparing pointers is not a safe way to check whether an allocation is tracked by lldb.
This change updates the lldb RenderScript internal hook callback to properly
identify and remove old allocations that had have an address that is currently
being tracked.

This change also removes the need for `lldb_private::renderscript::LookupAllocation`
to take a `create` flag, as this is now always the case.

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

Greg Clayton c226778768 We have many radars showing that stepping through C++ code can result in slow steps.
One of the things slowing us down is that ItaniumABILanguageRuntime class doesn't cache vtable to types in a map. This causes us, on every step, for every variable, to read the first pointer in a C++ type that could be dynamic and lookup the symbol, possibly in every symbol file (some symbols files on Darwin can end up having thousands of .o files when using DWARF in .o files, so thousands of .o files are searched each time). 

This fix caches lldb_private::Address (the resolved vtable symbol address in section + offset format) to TypeAndOrName instances inside the one ItaniumABILanguageRuntime in a process. This allows caching of dynamic types and stops us from always doing deep searches in each file.

as well, so this patch actually makes the code somewhat simpler.

A few methods were moved to a new file called ClangUtil, so that
they can be shared between ClangASTImporter and ClangASTContext
without creating a circular dependency between those two cpp
files.

Jim Ingham 6896b35585 Compilation can end up calling functions (e.g. to resolve indirect functions) so I added
a way for compilation to take a "thread to use for compilation".  If it isn't set then the
compilation will use the currently selected thread.  This should help keep function execution
to the one thread intended.

Sean Callanan 579e70c9b0 Add a DiagnosticManager replace error streams in the expression parser.
We want to do a better job presenting errors that occur when evaluating
expressions. Key to this effort is getting away from a model where all
errors are spat out onto a stream where the client has to take or leave
all of them.

To this end, this patch adds a new class, DiagnosticManager, which
contains errors produced by the compiler or by LLDB as an expression
is created. The DiagnosticManager can dump itself to a log as well as
to a string. Clients will (in the future) be able to filter out the
errors they're interested in by ID or present subsets of these errors
to the user.

This patch is not intended to change the *users* of errors - only to
thread DiagnosticManagers to all the places where streams are used. I
also attempt to standardize our use of errors a bit, removing trailing
newlines and making clients omit 'error:', 'warning:' etc. and instead
pass the Severity flag.

The patch is testsuite-neutral, with modifications to one part of the
MI tests because it relied on "error: error:" being erroneously
printed. This patch fixes the MI variable handling and the testcase.

Jim Ingham 8d94ba0fb1 This change introduces a "ExpressionExecutionThread" to the ThreadList.
Turns out that most of the code that runs expressions (e.g. the ObjC runtime grubber) on
behalf of the expression parser was using the currently selected thread.  But sometimes,
e.g. when we are evaluating breakpoint conditions/commands, we don't select the thread
we're running on, we instead set the context for the interpreter, and explicitly pass
that to other callers.  That wasn't getting communicated to these utility expressions, so
they would run on some other thread instead, and that could cause a variety of subtle and
hard to reproduce problems.  

I also went through the commands and cleaned up the use of GetSelectedThread.  All those
uses should have been trying the thread in the m_exe_ctx belonging to the command object
first.  It would actually have been pretty hard to get misbehavior in these cases, but for
correctness sake it is good to make this usage consistent.

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++.

That way you can set offset breakpoints that will move as the function they are

I don't align the new address to instruction boundaries yet, so you have to get
this right yourself for now.

Greg Clayton ae088e52f3 Now that SymbolFileDWARF supports having types in completely separate .pcm file with "-fmodules -gmodules", each SymbolFileDWARF can reference module DWARF info by looking in other DWARF files. Then if you have 1000 .o files that each reference one or more .pcm files in their debug info, a simple Module::FindTypes(...) call can end up searching the same .pcm file over and over and over. Now all internal FindTypes methods in classes (ModuleList, Module, SymbolFile) now take an extra argument:
llvm::DenseSet<lldb_private::SymbolFile *> &searched_symbol_files
    
Each time a SymbolFile::FindTypes() is called, it needs to check the searched_symbol_files list to make sure it hasn't already been asked to find the type and return immediately if it has been checked. This will stop circular dependencies from also crashing LLDB during type queries. 

This has proven to be an issue when debugging large applications on MacOSX that use DWARF in .o files.

Siva Chandra 9293fc4185 Better scheme to lookup alternate mangled name when looking up function address.
Summary:
This change is relevant for inferiors compiled with GCC. GCC does not
emit complete debug info for std::basic_string<...>, and consequently, Clang
(the LLDB compiler) does not generate correct mangled names for certain
functions.

This change removes the hard-coded alternate names in
ItaniumABILanguageRuntime.cpp.

Before the hard-coded names were put in ItaniumABILanguageRuntime.cpp, one could
not evaluate std::string methods (ex. std::string::length). After putting in
the hard-coded names, one could evaluate them. However, it did not still
enable one to call methods on, say for example, std::vector<string>.
This change makes that possible.

There is some amount of incompleteness in this change. Consider the
following example:

std::string hello("hello"), world("world");
std::map<std::string, std::string> m;
m[hello] = world;

One can still not evaluate the expression "m[hello]" in LLDB. Will
address this issue in another pass.
