bf36adeed4 Add boolean to PrintStackTraceOnErrorSignal to disable crash reporting.
The current crash reporting on Mac OS is only disabled via an environment variable.
This adds a boolean (default false) which can also disable crash reporting.

The only client right now is the unittests which don't ever want crash reporting, but do want to detect killed programs.

Reduces the time to run the APFloat unittests on my machine from

[----------] 47 tests from APFloatTest (51250 ms total)

to

[----------] 47 tests from APFloatTest (765 ms total)

0e407e7bbf [TableGen] Prevent invalid code generation when emitting AssemblerPredicate conditions.
Summary:
The loop which emits AssemblerPredicate conditions also links them together by emitting a '&&'.
If the 1st predicate is not an AssemblerPredicate, while the 2nd one is, nothing gets emitted for the 1st one, but we still emit the '&&' because of the 2nd predicate.
This generated code looks like "( && Cond2)" and is invalid.

93d8e23940 [lit] Skip gtest names starting with DISABLED_
The sanitizer test suite uses this idiom to disable a test.  Now that we
actually check if a test ran after invoking it, we see that zero tests
ran, and complain.

Instead, ignore tests starting with DISABLED_ completely. Fixes the
sanitizer test suite failures on Windows.

0123b6ee73 [lit] Fix running gtest type-parameterized tests on Windows
The '/' character in the test name of a type-parameterized test is not a
path separator, and should not be '\' on Windows. We were passing a test
name to --gtest_filter which found no tests, so the exit code was zero,
indicating a passed test.

This bug has been here since r84387 in 2009, when Jeff Yasskin added the
original lit support for type-paratermized tests. Somewhere along the
line some of the ValueMapTests started failing, but we can fix those
separately.

f09378397e [MCInstPrinter] Enable MCInstPrinter to change its behavior based on the
per-function subtarget.

Currently, code-gen passes the default or generic subtarget to the constructors
of MCInstPrinter subclasses (see LLVMTargetMachine::addPassesToEmitFile), which
enables some targets (AArch64, ARM, and X86) to change their instprinter's
behavior based on the subtarget feature bits. Since the backend can now use
different subtargets for each function, instprinter has to be changed to use the
per-function subtarget rather than the default subtarget.

This patch takes the first step towards enabling instprinter to change its
behavior based on the per-function subtarget. It adds a bit "PassSubtarget" to
AsmWriter which tells table-gen to pass a reference to MCSubtargetInfo to the
various print methods table-gen auto-generates. 

I will follow up with changes to instprinters of AArch64, ARM, and X86.

d3ab717935 Use std::bitset for SubtargetFeatures
Previously, subtarget features were a bitfield with the underlying type being uint64_t. 
Since several targets (X86 and ARM, in particular) have hit or were very close to hitting this bound, switching the features to use a bitset.
No functional change.

The first time this was committed (r229831), it caused several buildbot failures. 
At least some of the ARM ones were due to gcc/binutils issues, and should now be fixed.

8b41add6ca TableGen: Fix register class lane masks being too conservative.
When calculating the lanemask of a register class we have to include the
masks of subregisters supported by any of the class members, not just
the ones supported by all class members.

This fixes problems when coalescing towards a subclass with additional
subregisters available.

The attached testcase works fine as is, but does crash if you enable
subregister liveness on x86 without this change applied.

703b185464 Remove many superfluous SmallString::str() calls.
Now that SmallString is a first-class citizen, most SmallString::str()
calls are not required. This patch removes a whole bunch of them, yet
there are lots more.

There are two use cases where str() is really needed:
1) To use one of StringRef member functions which is not available in
SmallString.
2) To convert to std::string, as StringRef implicitly converts while 
SmallString do not. We may wish to change this, but it may introduce
ambiguity.

fe8490c22e TableGen: Use 'enum : uint64_t' for feature flags to fix -Wmicrosoft
clang-cl would warn that this value is not representable in 'int':
  enum { FeatureX = 1ULL << 31 };
All MS enums are 'ints' unless otherwise specified, so we have to use an
explicit type.  The AMDGPU target just hit 32 features, triggering this
warning.

Now that we have C++11 strong enum types, we can also eliminate the
'const uint64_t' codepath from tablegen and just use 'enum : uint64_t'.

There doesn't seem to be any need to assert that iterator assignment is

variable to iterate another node, that's perfectly acceptable. Just
don't mix comparisons between iterators into disjoint sequences, as
usual.

The keys of the map are unique by pointer address, so there's no need
to use the llvm::less comparator. This allows us to use DenseMap
instead, which reduces tblgen time by 20% on my stress test.

9379c31520 FileCheck: Add CHECK-SAME
Add `CHECK-SAME`, which requires that the pattern matches on the *same*
line as the previous `CHECK`/`CHECK-NEXT` -- in other words, no newline
is allowed in the skipped region.  This is similar to `CHECK-NEXT`,
which requires exactly 1 newline in the skipped region.

My motivation is to simplify checking the long lines of LLVM assembly
for the new debug info hierarchy.  This allows CHECK sequences like the
following:

    CHECK:      ![[REF]] = !SomeMDNode(
    CHECK-SAME: file: ![[FILE:[0-9]+]]
    CHECK-SAME: otherField: 93{{[,)]}}

which is equivalent to:

    CHECK: ![[REF]] = !SomeMDNode({{.*}}file: ![[FILE:[0-9]+]]{{.*}}otherField: 93{{[,)]}}

While this example just has two fields, many nodes in debug info have
more than that.  `CHECK-SAME` will keep the logic easy to follow.

Morever, it enables interleaving `CHECK-NOT`s without allowing newlines.
Consider the following:

    CHECK:      ![[REF]] = !SomeMDNode(
    CHECK-SAME: file: ![[FILE:[0-9]+]]
    CHECK-NOT:  unexpectedField:
    CHECK-SAME: otherField: 93{{[,)]}}
    CHECK-NOT:  otherUnexpectedField:
    CHECK-SAME: )

which doesn't seem to have an equivalent `CHECK` line.

4105fd49d4 AVX-512: Gather and Scatter patterns
Gather and scatter instructions additionally write to one of the source operands - mask register.
In this case Gather has 2 destination values - the loaded value and the mask.
Till now we did not support code gen pattern for gather - the instruction was generated from 
intrinsic only and machine node was hardcoded.
When we introduce the masked_gather node, we need to select instruction automatically,
in the standard way.
I added a flag "hasTwoExplicitDefs" that allows to handle 2 destination operands.

(Some code in the X86InstrFragmentsSIMD.td is commented out, just to split one big
patch in many small patches)

ca7e0787f0 CodeGen: convert CCState interface to using ArrayRefs
Everyone except R600 was manually passing the length of a static array

There should be no functional change, but out of tree targets may have
to tweak their calls as with these examples.

9f8d4037a6 AsmParser/Writer: Handle symbolic constants in DI 'flags:'
Parse (and write) symbolic constants in debug info `flags:` fields.
This prevents a readability (and CHECK-ability) regression with the new
debug info hierarchy.

Old (well, current) assembly, with pretty-printing:

    !{!"...\\0016387", ...} ; ... [public] [rvalue reference]

Flags field without this change:

   !MDDerivedType(flags: 16387, ...)

Flags field with this change:

   !MDDerivedType(flags: DIFlagPublic | DIFlagRValueReference, ...)

As discussed in the review thread, this isn't a final state.  Most of
these flags correspond to `DW_AT_` symbolic constants, and we might
eventually want to support arbitrary attributes in some form.  However,
as it stands now, some of the flags correspond to other concepts (like
`FlagStaticMember`); until things are refactored this is the simplest
way to move forward without regressing assembly.

8be39c81b0 Masked Gather and Scatter Intrinsics.
Gather and Scatter are new introduced intrinsics, comming after recently implemented masked load and store.
This is the first patch for Gather and Scatter intrinsics. It includes only the syntax, parsing and verification.

Gather and Scatter intrinsics allow to perform multiple memory accesses (read/write) in one vector instruction.
The intrinsics are not target specific and will have the following syntax:
Gather:
declare <16 x i32> @llvm.masked.gather.v16i32(<16 x i32*> <vector of ptrs>, i32 <alignment>, <16 x i1> <mask>, <16 x i32> <passthru>)
declare <8 x float> @llvm.masked.gather.v8f32(<8 x float*><vector of ptrs>, i32 <alignment>, <8 x i1> <mask>, <8 x float><passthru>)

Scatter:
declare void @llvm.masked.scatter.v8i32(<8 x i32><vector value to be stored> , <8 x i32*><vector of ptrs> , i32 <alignment>, <8 x i1> <mask>)
declare void @llvm.masked.scatter.v16i32(<16 x i32> <vector value to be stored> , <16 x i32*> <vector of ptrs>, i32 <alignment>, <16 x i1><mask> )

Vector of ptrs - a set of source/destination addresses, to load/store the value. 
Mask - switches on/off vector lanes to prevent memory access for switched-off lanes
vector of ptrs, value and mask should have the same vector width.

These are code examples where gather / scatter should be used and will allow function vectorization
;void foo1(int * restrict A, int * restrict B, int * restrict C) {
; for (int i=0; i<SIZE; i++) {
; A[i] = B[C[i]];
; }
;}

;void foo3(int * restrict A, int * restrict B) {
; for (int i=0; i<SIZE; i++) {
; A[B[i]] = i+5;
; }
;}

Tests will come in the following patches, with CodeGen and Vectorizer.

41a9ae532e Replace another std::set in the core of CodeGenRegister, this time with sorted arrays.
The hot path through this region of code does lots of batch inserts into sets. By storing them as sorted arrays, we can defer the sorting to the end of the batch, which is dramatically more efficient. This reduces tblgen runtime by 25% on my worst-case target.

35da384515 Change more of the guts of CodeGenRegister's RegUnit tracking to be based on bit vectors.
This is a continuation of my prior work to move some of the inner workings for CodeGenRegister to use bit vectors when computing about register units. This is highly beneficial to TableGen runtime on targets with large, dense register files. This patch represents a ~40% runtime reduction over and above my earlier improvement on a stress test of this case.

bc227b65c2 Change a very hot piece of code in TableGen's register unit computations to use bit vectors rather than arrays.
For target descriptions with very large and very dense register files, TableGen
can take an extremely long time to run.  This change makes a dent in that (~15%
in my measurements) by accelerating the single hottest operation with better data
structures.

I believe there's still a lot of room to make this even faster with more global
changes that require replacing some of the existing datastructures in this area
with bit vectors, but that's a more involved change and I wanted to get this
simpler improvement in first.

04bcc11905 Move DataLayout back to the TargetMachine from TargetSubtargetInfo
derived classes.

Since global data alignment, layout, and mangling is often based on the
DataLayout, move it to the TargetMachine. This ensures that global
data is going to be layed out and mangled consistently if the subtarget
changes on a per function basis. Prior to this all targets(*) have
had subtarget dependent code moved out and onto the TargetMachine.

*One target hasn't been migrated as part of this change: R600. The
R600 port has, as a subtarget feature, the size of pointers and
this affects global data layout. I've currently hacked in a FIXME
to enable progress, but the port needs to be updated to either pass
the 64-bitness to the TargetMachine, or fix the DataLayout to
avoid subtarget dependent features.

ae597a058a [emacs] llvm-mode: fix parens, font-lock i*
In llvm-mode, with electric-pair-mode turned on, typing a literal '['
would print out '[[', and '(' would print a '(('. This was a very
annoying bug caused by overzealous syntax-table entries: the parens are
already part of the '(' and ')' class by default. Fix this.

While at it, notice that i32, i64, i1 etc. are not font-locked despite a
clear intent to do so. The issue is that regexp-opt doesn't accept
regular expressions. So, spell out the common literal integers with
different widths.

c429da847f [emacs] Use c-mode-common-hook, derive from "gnu"
Make it clear that the "llvm.org" style is deriving from "gnu" style,
and use the c-mode-common-hook instead of c-mode-hook and c++-mode-hook.

230796b278 Intrinsics: introduce llvm_any_ty aka ValueType Any
Specifically, gc.result benefits from this greatly. Instead of:

gc.result.int.*
gc.result.float.*
gc.result.ptr.*
...

We now have a gc.result.* that can specialize to literally any type.

951d088ae7 [X86] Convert all the i8imm used by SSE and AVX instructions to u8imm.
This makes the assembler check their size and removes a hack from the disassembler to avoid sign extending the immediate.

e4f11175cb Use -Wl,defs when linking.
ELF linkers by default allow shared libraries to contain undefined references
and it is up to the dynamic linker to look for them.

On COFF and MachO, that is not the case.

This creates a situation where a .so might build on an ELF system, but the build
of the corresponding .dylib or .dll will fail.

This patch changes the cmake build to use -Wl,-z,defs when linking and updates
the dependencies so that -DBUILD_SHARED_LIBS=ON build still works.

b4c6267f7c Replace size method call of containers to empty method where appropriate
This patch was generated by a clang tidy checker that is being open sourced.
The documentation of that checker is the following:

/// The emptiness of a container should be checked using the empty method
/// instead of the size method. It is not guaranteed that size is a
/// constant-time function, and it is generally more efficient and also shows
/// clearer intent to use empty. Furthermore some containers may implement the
/// empty method but not implement the size method. Using empty whenever
/// possible makes it easier to switch to another container in the future.
