Aaron Watry f89bcca0b7 libclc/math: Add cospi 
Ported from the libclc/amd-builtins branch

v2: Rename sincos_f_piby4 to __libclc__sincosf_piby4
    Add cospi(double) implementation instead of using llvm.cos

Notes:
The sincosD_piby4.h file is mostly the same as the builtin implementation
released by AMD. The inline attribute declaration is changed, and M_PI is
used instead of a constant double. Otherwise, the only difference is that
the header explicitly enables the fp64 pragma.

llvm-svn: 225042
 2014-12-31 15:27:59 +00:00
Tom Stellard 1d77071e0d Require LLVM 3.6 and bump version to 0.1.0 
Some functions are implemented using hand-written LLVM IR, and
LLVM assembly format is allowed to change between versions, so we
should require a specific version of LLVM.

Jeroen Ketema 7a22aebbda Don't include <stddef.h> 
Including a standard or system header isn't allowed in OpenCL.

The type "size_t" needs to be explicitely defined now.

v2: Use __SIZE_TYPE__ instead of unsigned int.
v3: Define ptrdiff_t and NULL.

Aaron Watry 947bdd059a math: Add tan implementation 
Uses the algorithm:
tan(x) = sin(x) / sqrt(1-sin^2(x))

An alternative is:
tan(x) = sin(x) / cos(x)

Which produces more verbose bitcode and longer assembly.

Either way, the generated bitcode seems pretty nasty and a more optimized
but still precise-enough solution is welcome.

Aaron Watry 951ab64d19 math: Add asin implementation 
asin(x) = atan2(x, sqrt( 1-x^2 ))

alternatively:
asin(x) = PI/2 - acos(x)

Use the atan2 implementation since it produces slightly shorter bitcode and
R600 machine code.
