Hans Wennborg 361c287f0d CMake: don't install tablegen
Since it's an llvm-internal tool, we shouldn't install it.

Hans Wennborg 306db8f3fa CMake: Don't look for llvm-tblgen when building outside LLVM tree
Previously, the CMake build would look for llvm-tblgen to determine
if a directory is an LLVM build or install directory. Since we don't
want to include llvm-tblgen in the install, look for llvm-config instead,
and use that to find llvm-tblgen.

(This is the lld equivalent of Clang r189127.)

Dmitri Gribenko 1e50cbf366 Comment parsing: fix a bug where a line with whitespace between two paragraphs
would cause us to concatenate these paragraphs into a single one.

The no-op whitespace churn in test/Index test happened because these tests
don't use the correct approach for testing and are more strict than required
for they are testing.

Hans Wennborg fe06e811a3 CMake: build llvm-config on Windows.
It was previously not being built on Windows because the cmake file relied
on a sed script to generate a .in file that llvm-config needs.

By using cmake's configure_file function, we can get rid off the sed hack,
and also have this work on Windows.

Andrew Trick c01b00400d Adds cyclic critical path computation and heuristics, temporarily disabled.
Estimate the cyclic critical path within a single block loop. If the
acyclic critical path is longer, then the loop will exhaust OOO
resources after some number of iterations. If lag between the acyclic
critical path and cyclic critical path is longer the the time it takes
to issue those loop iterations, then aggressively schedule for
latency.

Jordan Rose 4c55d45b13 Respect -Wnewline-eof even in C++11 mode.
If the user has requested this warning, we should emit it, even if it's not
an extension in the current language mode. However, being an extension is
more important, so prefer the pedantic warning or the pedantic-compatibility
warning if those are enabled.

Daniel Jasper 0649d36172 clang-format: Fix indentation relative to unary expressions.
This should be done, only if we are still in the unary expression's
scope.

Before:
  bool aaaa = !aaaaaaaa(  // break
                   aaaaaaaaaaa);
  *aaaaaa = aaaaaaa( // break
       aaaaaaaaaaaaaaaa);

After:
  bool aaaa = !aaaaaaaa(  // break
                   aaaaaaaaaaa); // <- (unchanged)
  *aaaaaa = aaaaaaa( // break
      aaaaaaaaaaaaaaaa); // <- (no longer indented relative to "*")

The code was erroneously reading overflow area shadow from the TLS slot,

it can be overwritten by a nested vararg call, if that happens before va_start.

Richard Sandiford a481f58542 [SystemZ] Prefer LHI;ST... over LAY;MV...
If we had a store of an integer to memory, and the integer and store size
were suitable for a form of MV..., we used MV... no matter what.  We could
then have sequences like:

    lay %r2, 0(%r3,%r4)
    mvi 0(%r2), 4

In these cases it seems better to force the constant into a register
and use a normal store:

    lhi %r2, 4
    stc %r2, 0(%r3, %r4)

since %r2 is more likely to be hoisted and is easier to rematerialize.

Richard Sandiford 37cd6cfba2 Turn MipsOptimizeMathLibCalls into a target-independent scalar transform
...so that it can be used for z too.  Most of the code is the same.
The only real change is to use TargetTransformInfo to test when a sqrt
instruction is available.

The pass is opt-in because at the moment it only handles sqrt.

Pavel Labath 02b64d46a0 [analyzer] Refactor conditional expression evaluating code
Summary:
Instead of digging through the ExplodedGraph, to figure out which edge brought
us here, I compute the value of conditional expression by looking at the
sub-expression values.

To do this, I needed to change the liveness algorithm a bit -- now, the full
conditional expression also depends on all atomic sub-expressions, not only the
outermost ones.

David Majnemer 61c39a1ccd Sema: Properly support Microsoft-mode template arguments
Summary:
There were two things known to be wrong with our implementation of MSVC
mode template arguments:

- We didn't properly handle __uuidof/CXXUuidofExpr and skipped all type
  checking completely.
- We didn't allow for MSVC's extension of allowing certain constant
  "foldable" expressions from showing up in template arguments.
  They allow various casts dereference and address-of operations.
  We can make it more general as we find further peculiarities but this
  is the known extent.
