v3: change __builtin_nanf() to __builtin_nanf("")
    This doesn't work yet, but it was agreed to commit as-is with the logic
    that "broken" is better than "completely missing" and this should be
    fixed in clang.

v2: use __builtin_inff() and also add nan/huge_val definitions

There are two implementations of nextafter():
1. Using clang's __builtin_nextafter.  Clang replaces this builtin with
a call to nextafter which is part of libm.  Therefore, this
implementation will only work for targets with an implementation of
libm (e.g. most CPU targets).

2. The other implementation is written in OpenCL C.  This function is
known internally as __clc_nextafter and can be used by targets that
don't have access to libm.

Aaron Watry 99a2f3b274 Fix and re-enable R600 vload/vstore assembly
The assembly optimizations were making unsafe assumptions about which address
spaces had which identifiers.

Also, fix vload/vstore with 64-bit pointers. This was broken previously on
Radeon SI.

This version still only has assembly versions of int/uint 2/4/8/16 for global
loads and stores on R600, but it does it in a way that would be very easily
extended to private/local/constant and could also be handled easily on other
architectures.

v2: 1) Leave v[load|store]_impl.ll in generic/lib
    2) Remove vload_if.ll and vstore_if.ll interfaces
    3) Fix address+offset calculations

Tom Stellard 64b3bbae1e libclc: Add assembly versions of vstore for global [u]int4/8/16
The assembly should be generic, but at least currently R600 only supports
32-bit stores of [u]int1/4, and I believe that only global is well-supported.

R600 lowers the 8/16 component stores to multiple 4-component stores.

The unoptimized C versions of the other stuff is left in place.

Tom Stellard e78344dfae libclc: Implement clz() builtin
Squashed commit of the following:

commit a0df0a0e86c55c1bdc0b9c0f5a739e5adef4b056
Author: Aaron Watry <awatry@gmail.com>
Date:   Mon Apr 15 18:42:04 2013 -0500

    libclc: Rename clz.ll to clz_if.ll to ensure it gets built.

    configure.py treats files that have the same name with the .cl and .ll
    extensions as overriding eachother.

    E.g. If you have clz.cl and clz.ll both specified to be built in the same
    SOURCES file, only the first file listed will actually be built.

    Since the contents of clz.ll were an interface that is implemented in
    clz_impl.ll, rename clz.ll to clz_if.ll to make sure that the interface is
    built.

    libclc: llvm assembly implementation of clz

    libclc: Add stub clz builtin

    For scalar int/uint, attempt to use the clz llvm builtin.. for all others
    return 0 until an actual implementation is finished.

Tom Stellard 34f513df7c libclc: Add clamp(vec, scalar, scalar) and max(vec, scalar)
For any GENTYPE that isn't scalar, we need to implement a mixed
vector/scalar version of clamp/max.

This depends on the min() patches I sent to the list a few minutes ago.

Tom Stellard 075b31a2fa libclc: Implement the min(vec, scalar) version of the min builtin.
Checks if the current GENTYPE is scalar, and if not, then defines a separate

proceeding.

Tom Stellard 29b5b9816b libclc: Rename [add|sub]_sat.ll to [add|sub]_sat_if.ll
configure.py allows overloading *.cl with *.ll, but will only ever build
the first file listed in SOURCES of ${file}.cl and ${file}.ll

add_sat, sub_sat, (and the soon to be submitted clz) all define interfaces in
${function_name}.ll which are implemented in ${function_name}_impl.ll.

Renaming the interface files is enough to get them to build again, fixing
CL usage of these functions.

Tested on clover/r600g.

Tom Stellard 0bb381eaec libclc: implement rotate builtin
This implementation does a lot of bit shifting and masking. Suffice to say,
this is somewhat suboptimal... but it does look to produce correct results
(after the piglit tests were corrected for sign extension issues).

Someone who knows LLVM better than I could re-write this more efficiently.

Tom Stellard d54f6ba7b8 Allow targets to override generic implementations
Targets can override generic implementations by adding a file called
OVERRIDES in $(TARGET_DIR)/lib and listing the generic implementations
that it wants to override.  For example, to override get_group_id() and
get_global_size() you would add these lines to the OVERRIDES file:

workitem/get_group_id.cl
workitem/get_global_size.cl

- First introducing a versioning scheme
- Add --libexecdir, --includedir and --pkgconfigdir and prefill them as well as --prefix
- Build all targets by default
- Create clc.pc and install it in $pkgconfigdir
- Use clang++ instead of c++
- Rename builtins.bc to built_libs/$triple.bc and install them in $libexecdir
- Includes are installed recursively to $includedir
- Finally add $(DESTDIR) for 'make install'
