Sean Silva 1703e705cf [docs] Fix up some links to the preferred style.
:doc:`...` and :ref:`...` links help Sphinx keep track the dependencies
between documents and ensure that they are not pointing to nowhere.

Raw HTML links work just fine and are easier for people less familiar
with reST/Sphinx. They are easy to change over to the :doc:/:ref: style
after the fact so this is not a problem.

This commit doesn't fix all of them.

Duncan P. N. Exon Smith a5df813e51 RegAlloc: Account for a variable entry block frequency
Until r197284, the entry frequency was constant -- i.e., set to 2^14.
Although current ToT still has a constant entry frequency, since r197284
that has been an implementation detail (which is soon going to change).

  - r204690 made the wrong assumption for the CSRCost metric.  Adjust
    callee-saved register cost based on entry frequency.

  - r185393 made the wrong assumption (although it was valid at the
    time).  Update SpillPlacement.cpp::Threshold to be relative to the
    entry frequency.

Since ToT still has 2^14 entry frequency, this should have no observable
functionality change.

Diego Novillo c6574c1aa3 Add -pass-remarks flag to 'opt'.
Summary:
This adds support in 'opt' to filter pass remarks emitted by
optimization passes. A new flag -pass-remarks specifies which
passes should emit a diagnostic when LLVMContext::emitOptimizationRemark
is invoked.

This will allow the front end to simply pass along the regular
expression from its own -Rpass flag when launching the backend.

Depends on D3227.

Diego Novillo a9298b2297 Add support for optimization reports.
Summary:
This patch adds backend support for -Rpass=, which indicates the name
of the optimization pass that should emit remarks stating when it
made a transformation to the code.

Pass names are taken from their DEBUG_NAME definitions.

When emitting an optimization report diagnostic, the lack of debug
information causes the diagnostic to use "<unknown>:0:0" as the
location string.

This is the back end counterpart for

Before AllowShortFunctionsOnASingleLine could either be true, merging
all functions, or false, merging no functions. This patch adds a third
value "Inline", which can be used to only merge short functions defined
inline in a class, i.e.:

  void f() {
    return 42;
  }

  class C {
    void f() { return 42; }

Greg Clayton 86e70cb3ac Fixed an issue where if you called:
SBTarget::AddModule(const char *path,
                    const char *triple,
                    const char *uuid_cstr,
                    const char *symfile);
                    
If "symfile" was filled in, it would cause us to not correctly add the module. Same goes for:

SBTarget::AddModule(SBModuleSpec ...)

Where you filled in the symfile.

David Majnemer a1c861d379 obj2yaml: Use the correct relocation type for different machine types
The IO normalizer would essentially lump I386 and AMD64 relocations
together.  Relocation types with the same numeric value would then get
mapped in appropriately.

For example:
IMAGE_REL_AMD64_ADDR64 and IMAGE_REL_I386_DIR16 both have a numeric
value of one.  We would see IMAGE_REL_I386_DIR16 in obj2yaml conversions
of object files with a machine type of IMAGE_FILE_MACHINE_AMD64.

Andrew Trick 8d007bb5d4 Put a limit on ScheduleDAGSDNodes::ClusterNeighboringLoads to avoid blowing up compile time.
Fixes PR16365 - Extremely slow compilation in -O1 and -O2.

The SD scheduler has a quadratic implementation of load clustering
which absolutely blows up compile time for large blocks with constant
pool loads. The MI scheduler has a better implementation of load
clustering. However, we have not done the work yet to completely
eliminate the SD scheduler. Some benchmarks still seem to benefit from
early load clustering, although maybe by chance.

As an intermediate term fix, I just put a nice limit on the number of
DAG users to search before finding a match. With this limit there are no
binary differences in the LLVM test suite, and the PR16365 test case
does not suffer any compile time impact from this routine.
