Benjamin Kramer a25dcfd906 [VFS] Add an in-memory file system implementation.
This is a simple file system tree of memory buffers that can be filled by a
client. In conjunction with an OverlayFS it can be used to make virtual
files accessible right next to physical files. This can be used as a
replacement for the virtual file handling in FileManager and which I intend
to remove eventually.

Daniel Sanders d5a89418c5 [mips] Changed the way symbols are handled in dla and la instructions to allow simple expressions.
Summary:
An instruction like "(d)la $5, symbol+8" previously would have crashed the
assembler as it contains an expression. This is now fixed.
A few tests cases have also been changed to reflect these changes, however
these should only be syntax changes. Some new test cases have also been
added.

Rafael Espindola e3a20f57d9 Fix pr24486.
This extends the work done in r233995 so that now getFragment (in addition to
getSection) also works for variable symbols.

With that the existing logic to decide if a-b can be computed works even if
a or b are variables. Given that, the expression evaluation can avoid expanding
variables as aggressively and that in turn lets the relocation code see the
original variable.

In order for this to work with the asm streamer, there is now a dummy fragment
per section. It is used to assign a section to a symbol when no other fragment
exists.

This patch is a joint work by Maxim Ostapenko andy myself.

Anastasia Stulova b02e7835c5 [OpenCL] Fix casting a true boolean to an integer vector.
OpenCL v1.1 s6.2.2: for the boolean value true, every bit in the result vector should be set.

This change treats the i1 value as signed for the purposes of performing the cast to integer,
and therefore sign extend into the result.

The entries are added if there are "_init" or "_fini" entries in

entries are inserted even for undefined symbols.

Symbol names can be overridden by using -init and -fini command
line switches. If used, these switches neither add new symbol table
entries nor require those symbols to be resolved.

r249137 added support for the new mips-mti-linux toolchain. However,
the new tests of that commit, broke some buildbots because they didn't use

Angel Garcia Gomez c50b9fbb84 Fix bug in modernize-use-nullptr.
Summary:
https://llvm.org/bugs/show_bug.cgi?id=24960

modernize-use-nullptr would hit an assertion in some cases involving macros and initializer lists, due to finding a node with more than one parent (the two forms of the initializer list).

However, this doesn't mean that the replacement is incorrect, so instead of just rejecting this case I tried to find a way to make it work. Looking at the semantic form of the InitListExpr made sense to me (looking at both forms results in false negatives) but I am not sure of the things that we can miss by skipping the syntactic form.

Saleem Abdulrasool d170c4b57a Add -f[no-]declspec to control recognition of __declspec as a keyword
In versions of clang prior to r238238, __declspec was recognized as a keyword in
all modes.  It was then changed to only be enabled when Microsoft or Borland
extensions were enabled (and for CUDA, as a temporary measure).  There is a
desire to support __declspec in Playstation code, and possibly other
environments.  This commit adds a command-line switch to allow explicit
enabling/disabling of the recognition of __declspec as a keyword.  Recognition
is enabled by default in Microsoft, Borland, CUDA, and PS4 environments, and
disabled in all other environments.

Johannes Doerfert f17a78ef63 Remove non-executed statements during SCoP simplifcation
A statement with an empty domain complicates the invariant load

Johannes Doerfert 757a32b5b3 [FIX] Approximate non-affine loops correctly
Before isValidCFG() could hide the fact that a loop is non-affine by
  over-approximation. This is problematic if a subregion of the loop contains
  an exit/latch block and is over-approximated. Now we do not over-approximate
  in the isValidCFG function if we check loop control.  If such control is
  non-affine the whole loop is over-approximated, not only a subregion.

Summary:
The bitcode format is described in this document:
  https://drive.google.com/file/d/0B036uwnWM6RWdnBLakxmeDdOeXc/view
For more info on ThinLTO see:
  https://sites.google.com/site/llvmthinlto

The first customer is ThinLTO, however the data structures are designed
and named more generally based on prior feedback. There are a few
comments regarding how certain interfaces are used by ThinLTO, and the
options added here to gold currently have ThinLTO-specific names as the
behavior they provoke is currently ThinLTO-specific.

This patch includes support for generating per-module function indexes,
the combined index file via the gold plugin, and several tests
(more are included with the associated clang patch D11908).

Tobias Grosser d78616f98a Make ScopAnnotator a function-local variable to ensure it is freed at each run
When the ScopAnnotator was a class member variable some of the maps it contains
have not been properly cleared. As a result we had dangling pointers to
llvm::Value(s) which got detected by the AssertingVH we recently added.

No test case as this issue is hard to reproduce reliably as subsequent
optimizations need to delete some of the llvm::Values we still keep in our
lists.
