Removed the folowing interfaces either because their signatures have changed
in version 1.1 of the ABI or because they were implemented for ELF V2 ABI but
have actually been deprecated in version 1.1.

This hopefully helps to to address the following compile error on our buildbots
BlockGenerators.h:683:7: error: looser throw specifier for ‘virtual
polly::RegionGenerator::~RegionGenerator()’
BlockGenerators.h:164:11: error: overriding ‘virtual polly::BlockGenerator::~BlockGenerator() noexcept
(true)`

The immediate in the load/store should be scaled by the size of the memory
operation, not the size of the register being loaded/stored. This change gets
us one step closer to forming LDPSW instructions. This change also enables
pre- and post-indexing for halfword and byte loads and stores.

control the individual braces. The existing choices for brace wrapping
are now merely presets for the different flags that get expanded upon
calling the reformat function.
All presets have been chose to keep the existing formatting, so there
shouldn't be any difference in formatting behavior.
Also change the dump_format_style.py to properly document the nested
structs that are used to keep these flags discoverable among all the
configuration flags.

On some of our benchmarks this change shows about 50% compile time improvement without any noticeable performance difference.

Currently LLVM_COMPILER_IS_GCC_COMPATIBLE is set as a side-effect of determining
the stdlib to use in HandleLLVMStdlib, which causes problems when attempting to
use AddLLVM from an installed LLVM toolchain, as HandleLLVMStdlib is not used.
Move the setting of this variable into DetermineGCCCompatible and include that
from both AddLLVM and HandleLLVMStdlib.

If a PHI starts at a non-negative constant, monotonically increases
(only adds of a constant are supported at the moment) and that add
does not wrap, then the PHI is known never to be zero.

On android when debugging an apk we run lldb-server as application user
because the sell user (on non-rooted device) can't attach to an
application. The problem is that "adb pull" will run as a shell user
what can't access to files created by lldb-server because they will be
owned by the application user. This CL changes the oat symbolization
code to run "oatdump --symbolize" to generate an output what is owned
by the shell user.

alignment requirements, for example in the case of vectors.
These requirements are exploited by the code generator by using
move instructions that have similar alignment requirements, e.g.,
movaps on x86.
Although the code generator properly aligns the arguments with
respect to the displacement of the stack pointer it computes,
the displacement itself may cause misalignment. For example if
we have
%3 = load <16 x float>, <16 x float>* %1, align 64
call void @bar(<16 x float> %3, i32 0)
the x86 back-end emits:
movaps 32(%ecx), %xmm2
movaps (%ecx), %xmm0
movaps 16(%ecx), %xmm1
movaps 48(%ecx), %xmm3
subl $20, %esp <-- if %esp was 16-byte aligned before this instruction, it no longer will be afterwards
movaps %xmm3, (%esp) <-- movaps requires 16-byte alignment, while %esp is not aligned as such.
movl $0, 16(%esp)
calll __bar
To solve this, we need to make sure that the computed value with which
the stack pointer is changed is a multiple af the maximal alignment seen
during its computation. With this change we get proper alignment:
subl $32, %esp
movaps %xmm3, (%esp)

Summary: create a check that replaces 'std::unique_ptr<type>(new type(args...))' with 'std::make_unique<type>(args...)'. It was on the list of "Ideas for new Tools". It needs to be tested more carefully, but first I wanted to know if you think it is worth the effort.

Currently SimplifyDemandedVectorElts can only peek through bitcasts if the vectors have the same number of elements.
This patch fixes and enables some existing (disabled) code to support bitcasting to vectors with more/fewer elements. It currently only accepts cases when vectors alias cleanly (i.e. number of elements are an exact multiple of the other vector).
This was added to improve the demanded vector elements support for SSE vector shifts which require the __m128i (<2 x i64>) argument type to be bitcast to the vector type for the builtin shift. I've added extra tests for various additional bitcasts.

Recognize the main module header as well as different #include categories.
This should now mimic the behavior of llvm/utils/sort_includes.py as
well as clang-tools-extra/clang-tidy/llvm/IncludeOrderCheck.cpp very
closely.
llvm-svn: 248782
Every once in a while we see code that accesses memory with different types,
e.g. to perform operations on a piece of memory using type 'float', but to copy
data to this memory using type 'int'. Modeled in C, such codes look like:
void foo(float A[], float B[]) {
for (long i = 0; i < 100; i++)
*(int *)(&A[i]) = *(int *)(&B[i]);
for (long i = 0; i < 100; i++)
A[i] += 10;
}
We already used the correct types during normal operations, but fall back to our
detected type as soon as we import changed memory access functions. For these
memory accesses we may generate invalid IR due to a mismatch between the element
type of the array we detect and the actual type used in the memory access. To
address this issue, we always cast the newly created address of a memory access
back to the type of the memory access where the address will be used.

Besides a trivial MIPS support the patch introduces new TargetInfo class
member getDefaultEntry() to override default name of the entry symbol.

Summary: This patch adds block frequency analysis to LoopUnswitch pass to recognize hot/cold regions. For cold regions the pass only performs trivial unswitches since they do not increase code size, and for hot regions everything works as before. This helps to minimize code growth in cold regions and be more aggressive in hot regions. Currently the default cold regions are blocks with frequencies below 20% of function entry frequency, and it can be adjusted via -loop-unswitch-cold-block-frequency flag. The entire feature is controlled via -loop-unswitch-with-block-frequency flag and it is off by default.

Description.
If the simd clause is specified, the ordered regions encountered by any thread will use only a single SIMD lane to execute the ordered regions in the order of the loop iterations.
Restrictions.
An ordered construct with the simd clause is the only OpenMP construct that can appear in the simd region.
An ordered directive with ‘simd’ clause is generated as an outlined function and corresponding function call to prevent this part of code from vectorization later in backend.

Place new and update dbg.declare calls immediately after the
corresponding alloca.
Current code in replaceDbgDeclareForAlloca puts the new dbg.declare
at the end of the basic block. LLVM codegen has problems emitting
debug info in a situation when dbg.declare appears after all uses of
the variable. This usually kinda works for inlining and ASan (two
users of this function) but not for SafeStack (see the pending change
in http://reviews.llvm.org/D13178).

This is a bit of an awkward API and I'm not sure what the right solution
is. Having a publicly copy constructible base class makes it easy to
accidentally slice derived objects in a number of contexts.
