Tatyana Krasnukha 6c17cc531f [lldb] Make BreakpointResolver hold weak_ptr instead of raw pointer to breakpoint
This prevents calling Breakpoint::shared_from_this of an object that is not owned by any shared_ptr.

Jonas Devlieghere cdc514e4c6 [lldb] Update header guards to be consistent and compliant with LLVM (NFC)
LLDB has a few different styles of header guards and they're not very
consistent because things get moved around or copy/pasted. This patch
unifies the header guards across LLDB and converts everything to match
LLVM's style.

Alex Langford 2637769b9f [lldb] Remove LanguageRuntime::GetOverrideExprOptions
LanguageRuntime::GetOverrideExprOptions is specific to clang and was
only overridden in RenderScriptRuntime. LanguageRuntime in shouldn't
have any knowledge of clang, so remove it from LanguageRuntime and leave
it only in RenderScriptRuntime.

Raphael Isemann 95e264fc8a [lldb][NFC] Remove strange bool parameter from Searcher::SearchCallback
Summary:
The SearchCallback has a bool parameter that we always set to false, we never use in any callback implementation and that also changes its name
from one file to the other (either `containing` and `complete`). It was added in the original LLDB check in, so there isn't any history what
this was supposed to be, so let's just remove it.

Jonas Devlieghere 8b3af63b89 [NFC] Remove ASCII lines from comments
A lot of comments in LLDB are surrounded by an ASCII line to delimit the
begging and end of the comment.

Its use is not really consistent across the code base, sometimes the
lines are longer, sometimes they are shorter and sometimes they are
omitted. Furthermore, it looks kind of weird with the 80 column limit,
where the comment actually extends past the line, but not by much.
Furthermore, when /// is used for Doxygen comments, it looks
particularly odd. And when // is used, it incorrectly gives the
impression that it's actually a Doxygen comment.

I assume these lines were added to improve distinguishing between
comments and code. However, given that todays editors and IDEs do a
great job at highlighting comments, I think it's worth to drop this for
the sake of consistency. The alternative is fixing all the
inconsistencies, which would create a lot more churn.

Adrian Prantl 0e4c482124 Pass ConstString by value (NFC)
My apologies for the large patch. With the exception of ConstString.h
itself it was entirely produced by sed.

ConstString has exactly one const char * data member, so passing a
ConstString by reference is not any more efficient than copying it by
value. In both cases a single pointer is passed. But passing it by
value makes it harder to accidentally return the address of a local
object.

(This fixes rdar://problem/48640859 for the Apple folks)

Chandler Carruth 2946cd7010 Update the file headers across all of the LLVM projects in the monorepo
to reflect the new license.

We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.

Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

Zachary Turner 97206d5727 Rename Error -> Status.
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
serious.

Luke Drummond 47d6416189 Add a debuginfo version check for RenderScript modules
Added an extra field parser to the `RSModuleDescriptor` class enabling us to
check whether the versions of LLVM used to generated the debug symbols match
across the RenderScript compiler frontend (llvm-rs-cc) and backend (bcc); if
they do not, we warn the user that the debugging experience may be suboptimal
as LLVM IR debug information has no compatibility guarantees.

Aidan Dodds 21fed052e0 [Renderscript] Add commands for scriptgroup interaction.
This commit hooks the nofity function that signals script group
compilation.  By tracking scriptgroups compiled at runtine, users
are able to place breakpoints by script group name.  Breakpoints
will be placed on the kernels forming the group.

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.

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.

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

Enrico Granata 5f57b6ee0f Revert r268591
"Allow LanguageRuntimes to return an error if they fail in the course of dynamic type discovery

This is not meant to report that a value doesn't have a dynamic type - it is only meant as a mechanism to propagate actual type discovery issues (e.g. malformed type metadata for languages that have such a notion)

This information is used by ValueObjectDynamic to set its own m_error, which is a fairly sharp and heavyweight tool to begin with

For the time being, this is an architectural improvement but a practical no-op as no existing runtimes are actually setting errors"

I need to think about what I want to do in this space more carefully - this attempt might be too heavy of a hammer for the nail I am trying to fix, and I don't want to leave it in while I ponder
