Richard Smith d230de27f8 Remove and replace DiagStatePoint tracking and lookup data structure.
Rather than storing a single flat list of SourceLocations where the diagnostic
state changes (in source order), we now store a separate list for each FileID
in which there is a diagnostic state transition. (State for other files is
built and cached lazily, on demand.) This has two consequences:

1) We can now sensibly support modules, and properly track the diagnostic state
for modular headers (this matters when, for instance, triggering instantiation
of a template defined within a module triggers diagnostics).

2) It's much faster than the old approach, since we can now just do a binary
search on the offsets within the FileID rather than needing to call
isBeforeInTranslationUnit to determine source order (which is surprisingly
slow). For some pathological (but real world) files, this reduces total
compilation time by more than 10%.

For now, the diagnostic state points for modules are loaded eagerly. It seems
feasible to defer this until diagnostic state information for one of the
module's files is needed, but that's not part of this patch.

Arpith Chacko Jacob 99a1e0eba5 [OpenMP] Codegen support for 'target teams' on the host.
This patch adds support for codegen of 'target teams' on the host.
This combined directive has two captured statements, one for the
'teams' region, and the other for the 'parallel'.

This target teams region is offloaded using the __tgt_target_teams()
call. The patch sets the number of teams as an argument to
this call.

Arpith Chacko Jacob 19b911cb75 [OpenMP] Codegen support for 'target parallel' on the host.
This patch adds support for codegen of 'target parallel' on the host.
It is also the first combined directive that requires two or more
captured statements.  Support for this functionality is included in
the patch.

A combined directive such as 'target parallel' has two captured
statements, one for the 'target' and the other for the 'parallel'
region.  Two captured statements are required because each has
different implicit parameters (see SemaOpenMP.cpp).  For example,
the 'parallel' has 'global_tid' and 'bound_tid' while the 'target'
does not.  The patch adds support for handling multiple captured
statements based on the combined directive.

When codegen'ing the 'target parallel' directive, the 'target'
outlined function is created using the outer captured statement
and the 'parallel' outlined function is created using the inner
captured statement.

Justin Lebar 86c4e63ff9 [CUDA] Let NVPTX inherit the host's calling conventions.
Summary:
When compiling device code, we may still see host code with explicit
calling conventions.  NVPTX needs to claim that it supports these CCs,
so that (a) we don't raise noisy warnings, and (b) we don't break
existing code which relies on the existence of these CCs when
specializing templates.  (If a CC doesn't exist, clang ignores it, so
two template specializations which are different only insofar as one
specifies a CC are considered identical and therefore are an error if
that CC is not supported.)

Justin Lebar b662659355 [CUDA] More correctly inherit primitive types from the host during device compilation.
Summary:
CUDA lets users share structs between the host and device, so for that
and other reasons, primitive types such as ptrdiff_t should be the same
on both sides of the compilation.

Our code to do this wasn't entirely successful.  In particular, we did a
bunch of work during the NVPTXTargetInfo constructor, only to override
it in the NVPTX{32,64}TargetInfo constructors.  It worked well enough on
Linux and Mac, but Windows is LLP64, which is different enough to break
it.

This patch removes the NVPTX{32,64}TargetInfo classes entirely and fixes
the bug described above.

Dylan McKay 924fa3abdc Add AVR target and toolchain to Clang
Summary:
Authored by Senthil Kumar Selvaraj

This patch adds barebones support in Clang for the (experimental) AVR target. It uses the integrated assembler for assembly, and the GNU linker for linking, as lld doesn't know about the target yet.

The DataLayout string is the same as the one in AVRTargetMachine.cpp. The alignment specs look wrong to me, as it's an 8 bit target and all types only need 8 bit alignment. Clang failed with a datalayout mismatch error when I tried to change it, so I left it that way for now.

Marina Yatsina c42fd03bf8 [inline-asm]No error for conflict between inputs\outputs and clobber list
According to extended asm syntax, a case where the clobber list includes a variable from the inputs or outputs should be an error - conflict.
for example:

const long double a = 0.0;
int main()
{

char b;
double t1 = a;
__asm__ ("fucompp": "=a" (b) : "u" (t1), "t" (t1) : "cc", "st", "st(1)");

return 0;
}

This should conflict with the output - t1 which is st, and st which is st aswell.
The patch fixes it.

Yaxun Liu 8f66b4b44a Add support for non-zero null pointer for C and OpenCL
In amdgcn target, null pointers in global, constant, and generic address space take value 0 but null pointers in private and local address space take value -1. Currently LLVM assumes all null pointers take value 0, which results in incorrectly translated IR. To workaround this issue, instead of emit null pointers in local and private address space, a null pointer in generic address space is emitted and casted to local and private address space.

Tentative definition of global variables with non-zero initializer will have weak linkage instead of common linkage since common linkage requires zero initializer and does not have explicit section to hold the non-zero value.

Virtual member functions getNullPointer and performAddrSpaceCast are added to TargetCodeGenInfo which by default returns ConstantPointerNull and emitting addrspacecast instruction. A virtual member function getNullPointerValue is added to TargetInfo which by default returns 0. Each target can override these virtual functions to get target specific null pointer and the null pointer value for specific address space, and perform specific translations for addrspacecast.

Wrapper functions getNullPointer is added to CodegenModule and getTargetNullPointerValue is added to ASTContext to facilitate getting the target specific null pointers and their values.

This change has no effect on other targets except amdgcn target. Other targets can provide support of non-zero null pointer in a similar way.

This change only provides support for non-zero null pointer for C and OpenCL. Supporting for other languages will be added later incrementally.

which guarantee pointers are not null. These all seem to have useful
properties and correlations to document, in one case we even had it in
a comment but now it will also be an assert.

This should prevent PVS-Studio from incorrectly claiming that there are
a bunch of potential bugs here. But I feel really strongly that the
PVS-Studio warnings that pointed at this code have a far too high
false-positive rate to be entirely useful. These are just places where
there did seem to be a useful invariant to document and verify with an
assert. Several other places in the code were already correct and
already have perfectly clear code documenting and validating their
invariants, but still ran afoul of PVS-Studio.

It can be used together with a target triple to override support for some
extensions:

  // spir target supports all extensions, but we want to disable fp64
  clang -cc1 -triple spir-unknown-unknown -cl-ext=-cl_khr_fp64

Special 'all' extension allows to enable or disable all possible
extensions:

  // only fp64 will be supported
  clang -cc1 -triple spir-unknown-unknown -cl-ext=-all,+cl_khr_fp64
