Simon Tatham [Fri, 14 Dec 2018 11:39:55 +0000 (11:39 +0000)]
[TableGen:AsmWriter] Cope with consecutive tied operands.

When you define an instruction alias as a subclass of InstAlias, you
specify all the MC operands for the instruction it expands to, except
for operands that are tied to a previous one, which you leave out in
the expectation that the Tablegen output code will fill them in
automatically.

But the code in Tablegen's AsmWriter backend that skips over a tied
operand was doing it using 'if' instead of 'while', because it wasn't
expecting to find two tied operands in sequence.

So if an instruction updates a pair of registers in place, so that its
MC representation has two input operands tied to the output ones (for
example, Arm's UMLAL instruction), then any alias which wants to
expand to a special case of that instruction is likely to fail to
match, because the indices of subsequent operands will be off by one
in the generated printAliasInstr function.

This patch re-indents some existing code, so it's clearest when
viewed as a diff with whitespace changes ignored.

Introduce `AddressSpaceView` template parameter to `SizeClassAllocator32`, `FlatByteMap`, and `TwoLevelByteMap`.

Summary:
This is a follow up patch to r346956 for the `SizeClassAllocator32`
allocator.

This patch makes `AddressSpaceView` a template parameter both to the
`ByteMap` implementations (but makes `LocalAddressSpaceView` the
default), some `AP32` implementations and is used in `SizeClassAllocator32`.
The actual changes to `ByteMap` implementations and
`SizeClassAllocator32` are very simple. However the patch is large
because it requires changing all the `AP32` definitions, and users of
those definitions.

For ASan and LSan we make `AP32` and `ByteMap` templateds type that take
a single `AddressSpaceView` argument. This has been done because we will
instantiate the allocator with a type that isn't `LocalAddressSpaceView`
in the future patches. For the allocators used in the other sanitizers
(i.e. HWAsan, MSan, Scudo, and TSan) use of `LocalAddressSpaceView` is
hard coded because we do not intend to instantiate the allocators with
any other type.

In the cases where untemplated types have become templated on a single
`AddressSpaceView` parameter (e.g. `PrimaryAllocator`) their name has
been changed to have a `ASVT` suffix (Address Space View Type) to
indicate they are templated.  The only exception to this are the `AP32`
types due to the desire to keep the type name as short as possible.

In order to check that template is instantiated in the correct a way a
`static_assert(...)` has been added that checks that the
`AddressSpaceView` type used by `Params::ByteMap::AddressSpaceView` matches
the `Params::AddressSpaceView`. This uses the new `sanitizer_type_traits.h`
header.

[DAGCombiner][X86] Prevent visitSIGN_EXTEND from returning N when (sext (setcc)) already has the target desired type for the setcc

Summary:
If the setcc already has the target desired type we can reach the getSetCC/getSExtOrTrunc after the MatchingVecType check with the exact same types as the nodes we started with. This causes those causes VsetCC to be CSEd to N0 and the getSExtOrTrunc will CSE to N. When we return N, the caller will think that meant we called CombineTo and did our own worklist management. But that's not what happened. This prevents target hooks from being called for the node.

To fix this, I've now returned SDValue if the setcc is already the desired type. But to avoid some regressions in X86 I've had to disable one of the target combines that wasn't being reached before in the case of a (sext (setcc)). If we get vector widening legalization enabled that entire function will be deleted anyway so hopefully this is only for the short term.

the Google Objective-C style guide. The more descriptive diagnostics may

Unfortunately, gcc also implements 2 of the 3 function names here on X86 when lzcnt feature is enabled.

This patch adds builtins for these for MSVC compatibility and drops the forward declarations from intrin.h. To keep the gcc compatibility the two intrinsics that collided have been turned into macros that use the X86 specific builtins with the lzcnt feature check. These macros are only defined when _MSC_VER is not defined. Without them being macros we can get a redefinition error because -ms-extensions doesn't seem to set _MSC_VER but does make the MS builtins available.

and Four new API:
1) omp_set_affinity_format()
2) omp_get_affinity_format()
3) omp_display_affinity()
4) omp_capture_affinity()
The affinity format functionality has two ICV's associated with it:
affinity-display-var (bool) and affinity-format-var (string).
The affinity-display-var enables/disables the functionality through the
envirable OMP_DISPLAY_AFFINITY. The affinity-format-var is a formatted
string with the special field types beginning with a '%' character
similar to printf
For example, the affinity-format-var could be:
"OMP: host:%H pid:%P OStid:%i num_threads:%N thread_num:%n affinity:{%A}"

The affinity-format-var is displayed by every thread implicitly at the beginning
of a parallel region when any thread's affinity has changed (including a brand
new thread being spawned), or explicitly using the omp_display_affinity() API.
The omp_capture_affinity() function can capture the affinity-format-var in a
char buffer. And omp_set|get_affinity_format() allow the user to set|get the
affinity-format-var explicitly at runtime. omp_capture_affinity() and
omp_get_affinity_format() both return the number of characters needed to hold
the entire string it tried to make (not including NULL character). If not

Summary:
This patch computes the synthetic function entry count on the whole
program callgraph (based on module summary) and writes the entry counts
to the summary. After function importing, this count gets attached to
the IR as metadata. Since it adds a new field to the summary, this bumps
up the version.

[llvm-size][libobject] Add explicit "inTextSegment" methods similar to "isText" section methods to calculate size correctly.

Summary:
llvm-size uses "isText()" etc. which seem to indicate whether the section contains code-like things, not whether or not it will actually go in the text segment when in a fully linked executable.

[clang-tidy] Add the abseil-duration-subtraction check

Summary:
This check uses the context of a subtraction expression as well as knowledge
about the Abseil Time types, to infer the type of the second operand of some
subtraction expressions in Duration conversions. For example:

   absl::ToDoubleSeconds(duration) - foo

can become
   absl::ToDoubleSeconds(duration - absl::Seconds(foo))

This ensures that time calculations are done in the proper domain, and also
makes it easier to further deduce the types of the second operands to these
