Introduce ScopStmt::getEntryBlock(). NFC.
This replaces an ungly inline ternary operator pattern.

Introduce Scop::getStmtFor. NFC.
Replace Scop::getStmtForBasicBlock and Scop::getStmtForRegionNode, and
add overloads for llvm::Instruction and llvm::RegionNode.
getStmtFor and overloads become the common interface to get the Stmt
that contains something. Named after LoopInfo::getLoopFor and
RegionInfo::getRegionFor.

Add assertions checking def dominates use. NFC.
This is also be caught by the function verifier, but disconnected from
the place that produced it. Catch it already at creation to be able to
reason more directly about the cause.
llvm-svn: 261790
Add assertion to MemoryAccess::addIncoming. NFC.
MemoryAccess::addIncoming exists to remember which values come from that
statement in PHI writes, relevant for subregions that have multiple
exiting edges to an exit block. The exit block can be separated from the
exiting block by regions simplifications. It should not be called for
any read accesses.
llvm-svn: 261789
Use inline variable declaration. NFC.
llvm-svn: 261788
Replace std::auto_ptr with std::unique_ptr. NFC.
std::auto_ptr has been deprecated in C++11, which some compilers warn
about.
llvm-svn: 261787
Tidy test case. NFC.
The test style guide defines that opt should get its input from stdin.
(instead by file argument to avoid that the file name appears in its
output)
CHECK-FORCED is not recognized by FileCheck; remove it.
llvm-svn: 261786
Proofreading comments in DependenceInfo.h. NFC.
Typos, commas and other minor changes

[CUDA] Mark all CUDA device-side function defs, decls, and calls as convergent.
Summary:
This is important for e.g. the following case:
void sync() { __syncthreads(); }
void foo() {
do_something();
sync();
do_something_else():
}
Without this change, if the optimizer does not inline sync() (which it
won't because __syncthreads is also marked as noduplicate, for now
anyway), it is free to perform optimizations on sync() that it would not
be able to perform on __syncthreads(), because sync() is not marked as
convergent.
Similarly, we need a notion of convergent calls, since in the case when
we can't statically determine a call's target(s), we need to know
whether it's safe to perform optimizations around the call.
This change is conservative; the optimizer will remove these attrs where
it can, see r260318, r260319.

[CUDA] do not allow attribute-based overloading for __global__ functions.
__global__ functions are present on both host and device side,
so providing __host__ or __device__ overloads is not going to
do anything useful.

[CUDA] Add conversion operators for threadIdx, blockIdx, gridDim, and blockDim to uint3 and dim3.
Summary:
This lets you write, e.g.
uint3 a = threadIdx;
uint3 b = blockIdx;
dim3 c = gridDim;
dim3 d = blockDim;
which is legal in nvcc, but was not legal in clang.
The fact that e.g. the type of threadIdx is not actually uint3 is still
observable, but now you have to try to observe it.

[CUDA] Add hack so code which includes "curand.h" doesn't break.
Summary:
curand.h includes curand_mtgp32_kernel.h. In host mode, this header
redefines threadIdx and blockDim, giving them their "proper" types of
uint3 and dim3, respectively.
clang has its own plan for these variables -- their types are magic
builtin classes. So these redefinitions are incompatible.
As a hack, we force-include the offending CUDA header and use #defines
to get the right types for threadIdx and blockDim.

Test-only change.
llvm-svn: 261775
Bail on compilation as soon as a job fails.
Summary:
(Re-land of r260448, which was reverted in r260522 due to a test failure
in Driver/output-file-cleanup.c that only showed up in fresh builds.)
Previously we attempted to be smart; if one job failed, we'd run all
jobs that didn't depend on the failing job.
Problem is, this doesn't work well for e.g. CUDA compilation without
-save-temps. In this case, the device-side and host-side Assemble
actions (which actually are responsible for preprocess, compile,
backend, and assemble, since we're not saving temps) are necessarily
distinct. So our clever heuristic doesn't help us, and we repeat every
error message once for host and once for each device arch.
The main effect of this change, other than fixing CUDA, is that if you
pass multiple cc files to one instance of clang and you get a compile
error, we'll stop when the first cc1 job fails.

Make test/Driver/output-file-cleanup.c hermetic.
Summary:
It checks that certain files do and exist, so make sure that they don't
exist at the beginning of the test.
This hid a failure in r260448; to see the failure, you had to run the test with
a clean-ish objdir.

Some fixes for case insensitive paths on Windows.
Paths on Windows are not case-sensitive. Because of this, if a file
is called main.cpp, you should be able to set a breakpoint on it
by using the name Main.cpp. In an ideal world, you could just
tell people to match the case, but in practice this can be a real
problem as it requires you to know whether the person who compiled
the program ran "clang++ main.cpp" or "clang++ Main.cpp", both of
which would work, regardless of what the file was actually called.

Fix rejects-valid caused by r261297.
r261297 called hasUserProvidedDefaultConstructor() to check if defining a
const object is ok. This is incorrect for this example:
struct X { template<typename ...T> X(T...); int n; };
const X x; // formerly OK, now bogus error
Instead, track if a class has a defaulted default constructor, and disallow
a const object for classes that either have defaulted default constructors or
if they need an implicit constructor.

ELF: Do not instantiate InputSectionBase::Discarded.
"Discarded" section is a marker for discarded sections, and we do not
use the instance except for checking its identity. In that sense, it
is just another type of a "null" pointer for InputSectionBase. So,
it doesn't have to be a real instance of InputSectionBase class.
In this patch, we no longer instantiate Discarded section but instead
use -1 as a pointer value. This eliminates a global variable which
needed initialization at startup.

[Renderscript] Change expression strings to use portable format specifiers.
Mips64 tests were failing on windows because the sscanf implementation differs between clang/gcc/msvc such that on windows %lx specifies a 32bits parameter and %llx is for 64bits. For us this meant that 64bit pointers were being truncated to 32bits on their way into a JIT'd expression.

Default vaarg lowering should support indirect struct types.
Fixes PR11517 for SPARC.
On most targets, clang lowers va_arg itself, eschewing the use of the
llvm vaarg instruction. This is necessary (at least for now) as the type
argument to the vaarg instruction cannot represent all the ABI
information that is needed to support complex calling conventions.
However, on targets with a simpler varrags ABIs, the LLVM instruction
can work just fine, and clang can simply lower to it. Unfortunately,
even on such targets, vaarg with a struct argument would fail, because
the default lowering to vaarg was naive: it didn't take into account the
ABI attribute computed by classifyArgumentType. In particular, for the
DefaultABIInfo, structs are supposed to be passed indirectly and so
llvm's vaarg instruction should be emitted with a pointer argument.
Now, vaarg instruction emission is able to use computed ABIArgInfo for
the provided argument type, which allows the default ABI support to work
for structs too.
I haven't touched the EmitVAArg implementation for PPC32_SVR4 or XCore,
although I believe both are now redundant, and could be switched over to
use the default implementation as well.
