This adds a new SystemZ-specific intrinsic, llvm.s390.tdc.f(32|64|128),
which maps straight to the test data class instructions. A new IR pass
is added to recognize instructions that can be converted to TDC and
perform the necessary replacements.

There is no polymorphism here, and StreamRef already contains a
StreamInterface pointer. Dropping the base class makes StreamRef more
transparent to the compiler, for example it can find unused variables.
llvm-svn: 275013
Some abstractions in LLVM "know" that they are reading in-bounds,
FixedStreamArray, and provide a simple result. This breaks down if the
stream map is bogus.

We are currently using add_llvm_utility for executable targets that:
1. Are built by default.
2. Used for testing.
3. Are not installed by default.
Originally, lli-child-target used add_llvm_tool instead of add_llvm_executable
directly. This was changed so that lli-child-target would not be installed. This
was good since this is only used for testing and should never be installed for
users. This also had the unfortunate side effect that one can never turn off the
building of lli-child-target by default, a regression for projects that by
default do not want to compile any LLVM tools beyond tablegen/llvm-config.
This patch changes lli-child-target to use add_llvm_utility. This makes sense
since:
1. lli-child-target matches the semantics of executables created with
add_llvm_utility.
2. We fix the regression since now one can use the flag LLVM_BUILD_UTILS to
eliminate default compilation.

This option is the equivalent option to LLVM_BUILD_TOOLS but for executables
created via add_llvm_utility.
This is a useful tool for improving compile time in situations where LLVM is
used as a library and no testing tools are needed.
It follows the exact same implemention model as LLVM_BUILD_TOOLS.
Since the option is by default set to on, no behavior is changed unless one sets
it from the command line to be false.
llvm-svn: 275007
LLVM_BUILD_TOOLS is a boolean variable that controls whether or not generated
targets for llvm tools are built by the "all" target. CLANG_BUILD_TOOLS is an
analogous variable for clang targets.
This is useful functionality for selectively disabling the building of clang
targets by default to speed up builds.
In terms of implementation, I just followed the model of LLVM's implementation
of this functionality.

In the solver, isUndefined() does really mean "we don't know the
value yet" rather than "this is an UndefinedValue". Discussed with
Eli Friedman.

Only MipsThunk were using the function, and the way how it wrote
thunk contents was different from ARM thunks. This patch makes
them consistent.
llvm-svn: 274997
Although they are in the same .cpp file, the way they were written
were slightly different, so they looked more different than they were.
This patch makes their styles consistent.
llvm-svn: 274996
This code was already commented out and it made some weird assumptions,
e.g. using isUndefined() as "this value is UndefValue" instead of
"we haven't computed this value is yet". Thanks to Eli Friedman for
pointing out where I was wrong (and where this code was wrong).

This matches how LLVM has its cmake files organized and is cleaner than just
shoving this business logic into the main CMakeLists.txt.

MASM (ML.exe and ML64.exe) and older versions of MSVC (CL.exe) support a
flag called /Zd which is more-or-less -gline-tables-only.
It seems nicer to support this flag instead of exposing
-gline-tables-only.

These test in this change are objc++, but are built using %clang, not %clangxx.
The reason this works is the driver has been adding -lc++ for sanitizer enabled
builds. By making these tests use %clangxx, they no longer depend on the driver
linking to c++. Doing so will allow us to prevent overlinking of libc++ for
applications.

Summary:
Previously, the added test cases crashed because the passed a null Decl
to addUsage().

Don't create unnecessary truncations if the result will not be used.
Also prefer preforming math before the truncation, it makes it a little
easier to reason about.

ConstantInt::getSExtValue may fail on >64-bit integers. Add checks to call
getSExtValue only on narrow integers.
As a minor aside, simplify slsr-gep.ll to remove unnecessary load instructions.

Summary: ASCII case sorting does not help finding imported symbols quickly, and it is common to have e.g. class Foo and function fooFactory exported/imported from the same file.
