Jordan Rose cea01ee939 CMake: Use check_symbol_exists instead of check_cxx_symbol_exists.
check_cxx_symbol_exists requires CMake 2.8.6, so even though I
recommended it to Owen it's probably better to stay away for now.
This check is not technically correct because we're checking <math.h>
but then using <cmath> in the actual code, but if we run into problems we
can do the same sort of dance as isinf() and isnan() where we check /both/
headers and then write a wrapper header around them.

Owen Anderson 132ae8b955 Conditionalize constant folding of math intrinsics on the availability of an implementation on the host. This is a little bit unfortunate, but until someone decides to implement a full libm for APFloat, we don't have a better way to get this functionality.

Edwin Vane a9c5bb3ff3 Turn off uninitialized-use warnings for gcc in cmake build
Added support to the cmake build to turn off uninitialized use warnings
for gcc. This cleans the build up somewhat.

Used logic simpler than found in autoconf by making use of the fact that
although gcc won't complain about unsupported -Wno-* flags it *will*
complain about unsupported -W flags.

Chandler Carruth ef7f968e09 Add time getters to the process interface for requesting the elapsed
wall time, user time, and system time since a process started.

For walltime, we currently use TimeValue's interface and a global
initializer to compute a close approximation of total process runtime.

For user time, this adds support for an somewhat more precise timing
mechanism -- clock_gettime with the CLOCK_PROCESS_CPUTIME_ID clock
selected.

For system time, we have to do a full getrusage call to extract the
system time from the OS. This is expensive but unavoidable.

In passing, clean up the implementation of the old APIs and fix some
latent bugs in the Windows code. This might have manifested on Windows
ARM systems or other systems with strange 64-bit integer behavior.

The old API for this both user time and system time simultaneously from
a single getrusage call. While this results in fewer system calls, it
also results in a lower precision user time and if only user time is
desired, it introduces a higher overhead. It may be worthwhile to switch
some of the pass timers to not track system time and directly track user
and wall time. The old API also tracked walltime in a confusing way --
it just set it to the current walltime rather than providing any measure
of wall time since the process started the way buth user and system time
are tracked. The new API is more consistent here.

The plan is to eventually implement these methods for a *child* process
by using the wait3(2) system call to populate an rusage struct
representing the whole subprocess execution. That way, after waiting on
a child process its stats will become accurate and cheap to query.

Sebastian Pop faeca292a2 enable cross compilation with cmake
This patch allows us to use cmake to specify a cross compiler: target different
than host. In particular, it moves LLVM_DEFAULT_TARGET_TRIPLE and TARGET_TRIPLE
variables from cmake/config-ix.cmake to the toplevel CMakeLists.txt to make them
available at configure time.

Here is the command line that I have used to test my patches to create a Hexagon
cross compiler hosted on x86:

$ cmake -G Ninja -D LLVM_TARGETS_TO_BUILD:STRING=Hexagon -D TARGET_TRIPLE:STRING=hexagon-unknown-linux-gnu -D LLVM_DEFAULT_TARGET_TRIPLE:STRING=hexagon-unknown-linux-gnu -D LLVM_TARGET_ARCH:STRING=hexagon-unknown-linux-gnu ..

This patch allows us to use cmake to specify a cross compiler for Hexagon.

available at configure time. Here is the command line that I have used to test
my patches:

Sebastian Pop 0f357d6c22 use getHostTriple instead of getDefaultTargetTriple in getClosestTargetForJIT
Get back getHostTriple.

For JIT compilation, use the host triple instead of the default
target: this fixes some JIT testcases that used to fail when the
compiler has been configured as a cross compiler.

Oscar Fuentes f2ab92833a Handle changing of LLVM_ENABLE_FFI.
If someone first configure build with LLVM_ENABLE_FFI=1 and then turn it
off, the build will fail in lib/ExecutionEngine/Interpreter because
Interpreter will try still to #include <ffi/ffi.h>, but there are no
include_directories(${FFI_INCLUDE_DIR}) now.

This patch unset()'s HAVE_FFI_H and HAVE_FFI_FFI_H from cache file if
LLVM_ENABLE_FFI=0. This forces CMake to update config.h.
