If we don't have futimens(), we fall back to futimes(), which only supports
microsecond timestamps. In that case, we need to explicitly cast away the extra
precision in setLastModificationAndAccessTime().

Summary:
Most of the changes are very straight-forward. The only choice I had to make was
to use second-precision time points in the Archive classes. I did this because
the archive files use that precision in the on-disk representation anyway.

Summary:
Add relocations for AArch64 ILP32. Includes:
  - Addition of definitions for R_AARCH32_*
  - Definition of new -target-abi: ilp32
  - Definition of data layout string
  - Tests for added relocations. Not comprehensive, but matches
    existing tests for 64-bit. Renames "CHECK-OBJ" to "CHECK-OBJ-LP64".
  - Tests for llvm-readobj

Summary:
These are good candidates for jump threading. This enables later opts
(such as InstCombine) to combine instructions from the selects with
instructions out of the selects. SimplifyCFG will fold the select
again if unfolding wasn't worth it.

It's quite sad that we have to edit so many files just to add a register. I am

Summary:
This is a follow-up to D25416. It removes all usages of TimeValue from
llvm/Support library (except for the actual TimeValue declaration), and replaces
them with appropriate usages of std::chrono. To facilitate this, I have added
small utility functions for converting time points and durations into appropriate
OS-specific types (FILETIME, struct timespec, ...).

[X86][AVX512][Clang][Intrinsics][reduce] Adding missing reduce (Operators: +,*,&&,||) intrinsics to Clang

Committed after LGTM and check-all

Vector-reduction arithmetic accepts vectors as inputs and produces scalars as outputs.
This class of vector operation forms the basis of many scientific computations.
In vector-reduction arithmetic, the evaluation off is independent of the order of the input elements of V.

Used bisection method. At each step, we partition the vector with previous
step in half, and the operation is performed on its two halves.
This takes log2(n) steps where n is the number of elements in the vector.

Add synci to the microMIPS instruction definitions, mark the MIPS sync & synci
as not being part of microMIPS. This does not cover the sync instruction alias,
as that will be handled with a different patch. Add sync to the valid tests for

This commit improves the '-Wformat' warnings by ensuring that the formatting

This checker does not emit reports, however it influences the analysis
by providing complete summaries for, or otherwise improving modeling of,
various standard library functions.

This should reduce the number of infeasible paths explored during analysis.
The custom function summary format used in this checker is superior to
body farms by causing less unnecessary state splits,
which would result in better analysis performance.

has no field declaration.

This commit fixes an invalid Winitializer-overrides warning that's shown
when analyzing a second (or any after the first) instantiation of a designated
initializer. This invalid warning is fixed by making sure that a
DesignatedInitExpr is rebuilt by the tree transformer when it has a field
designator whose FieldDecl* hasn't been yet initialized. This ensures that a
different DesignatedInitExpr is processed by Sema for every instantiation, and
thus the invalid warning is avoided.
