[Power9] Part-word VSX integer scalar loads/stores and sign extend instructions

This patch corresponds to review:
https://reviews.llvm.org/D23155

This patch removes the VSHRC register class (based on D20310) and adds
exploitation of the Power9 sub-word integer loads into VSX registers as well
as vector sign extensions.
The new instructions are useful for a few purposes:

    Int to Fp conversions of 1 or 2-byte values loaded from memory
    Building vectors of 1 or 2-byte integers with values loaded from memory
    Storing individual 1 or 2-byte elements from integer vectors

This patch implements all of those uses.

8 years ago[cmake] Reintroduce (ldconfig-compatible) SOVERSIONs on shared libraries

[cmake] Reintroduce (ldconfig-compatible) SOVERSIONs on shared libraries

Reintroduce versioning of shared libraries via SOVERSION, addressing
the issues with the previous design, since Gentoo is relying
on shared-split install of LLVM. The SOVERSIONs were originally
introduced in r229720 for all libraries, and removed in r252093 in favor
of custom SONAME. As far as I understand, the major concern with the old
versioning was that the used versions were incompatible with ldconfig.

Having considered that, this commit introduce SOVERSIONS with the
following considerations:

1. SOVERSIONs are formed of major & minor version concatenated -- i.e.
for 4.0 its .so.40. This matches the common practice where the first
version number indicates ABI breakage, and therefore fixes the issues
with ldconfig. Additionally, VERSION with the remaining verion
components appended is used, however this is not strictly necessary.

2. The versioning is only applied to libraries with no explicit SONAME
specified -- i.e. it won't apply to libLLVM but only to the split
libraries. It will also apply to libraries installed by the subprojects.

3. The versioning is only done on *nix systems, Darwin excluded. This
matches the current use of SONAME.

Codegen: Tail-duplicate during placement.

The tail duplication pass uses an assumed layout when making duplication
decisions. This is fine, but passes up duplication opportunities that
may arise when blocks are outlined. Because we want the updated CFG to
affect subsequent placement decisions, this change must occur during
placement.

In order to achieve this goal, TailDuplicationPass is split into a
utility class, TailDuplicator, and the pass itself. The pass delegates
nearly everything to the TailDuplicator object, except for looping over
the blocks in a function. This allows the same code to be used for tail
duplication in both places.

This change, in concert with outlining optional branches, allows
triangle shaped code to perform much better, esepecially when the
taken/untaken branches are correlated, as it creates a second spine when
the tests are small enough.

Refactor the Args class.

There were a number of issues with the Args class preventing
efficient use of strings and incoporating LLVM's StringRef class.
The two biggest were:

1. Backing memory stored in a std::string, so we would frequently
   have to use const_cast to get a mutable buffer for passing to
   various low level APIs.
2. backing std::strings stored in a std::list, which doesn't
   provide random access.

I wanted to solve these two issues so that we could provide
StringRef access to the underlying arguments, and also a way
to provide range-based access to the underlying argument array
while still providing convenient c-style access via an argv style
const char**.

The solution here is to store arguments in a single "entry" class
which contains the backing memory, a StringRef with precomputed
length, and the quote char.  The backing memory is a manually
allocated const char* so that it is not invalidated when the
container is resized, and there is a separate argv array provided

These diagnostics are separate from the path-sensitive engine's path notes,
and can be added manually on top of path-sensitive or path-insensitive reports.

The new note diagnostics would appear as note:-diagnostic on console and
as blue bubbles in scan-build. In plist files they currently do not appear,
because format needs to be discussed with plist file users.

The analyzer option "-analyzer-config notes-as-events=true" would convert
notes to normal path notes, and put them at the beginning of the path.
This is a temporary hack to show the new notes in plist files.

A few checkers would be updated in subsequent commits,
including tests for this new feature.

8 years ago[lit] Throw in unimplemented method (NFC)
Chris Bieneman [Mon, 3 Oct 2016 04:48:22 +0000 (04:48 +0000)]
[lit] Throw in unimplemented method (NFC)

Summary:
lit's `OneCommandFileTest` class implements an abstract method that
raises if called. However, it raises by referencing an undefined
symbol. Instead, raise explicitly by throwing a `NotImplementedError`.
This is clearer, and appeases Python linters.
