Jan Vesely a82e080b57 AMDGPU: Implement get_global_offset builtin
Also fix get_global_id to consider offset
No idea how to add this for ptx, so they are stuck with the old get_global_id
implementation.

v2: split to a separate patch

v3: Switch R600 to use implictarg.ptr

Aaron Watry 8872800eff math: Add frexp ported from amd-builtins
The float implementation is almost a direct port from the amd-builtins,
but instead of just having a scalar and float4 implementation, it has
a scalar and arbitrary width vector implementation.

The double scalar is also a direct port from AMD's builtin release.

The double vector implementation copies the logic in the float vector
implementation using the values from the double scalar version.

Both have been tested in piglit using tests sent to that project's
mailing list.

Tom Stellard a64bad8338 Use a more accurate implementation for exp
Using exp2(x * M_LOG2E_F) does not give us accurate enough results for

input in part of the calculation.

Tom Stellard d9ca1f1596 configure: Add --enable-runtime-subnormal option
This makes it possible for runtime implementations to disable
subnormal handling at runtime.

When this flag is enabled, decisions about how to handle subnormals
in the library will be controlled by an external variable called
__CLC_SUBNORMAL_DISABLE.

Function implementations should use these new helpers for querying subnormal
support:
__clc_fp16_subnormals_supported();
__clc_fp32_subnormals_supported();
__clc_fp64_subnormals_supported();

In order for the library to link correctly with this feature,
users will be required to either:

1. Insert this variable into the module (if using the LLVM/Clang C++/C APIs).

2. Pass either subnormal_disable.bc or subnormal_use_default.bc to the
linker.  These files are distributed with liblclc and installed to
$(installdir).  e.g.:

llvm-link -o kernel-out.bc kernel.bc builtins-nosubnormal.bc subnormal_disable.bc

or

llvm-link -o kernel-out.bc kernel.bc builtins-nosubnormal.bc subnormal_use_default.bc

If you do not supply the --enable-runtime-subnormal then the library
behaves the same as it did before this commit.

In addition to these changes, the patch adds helper functions that
should be used when implementing library functions that need
special handling for denormals:

__clc_fp16_subnormals_supported();
__clc_fp32_subnormals_supported();
__clc_fp64_subnormals_supported();

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 13116cf01a relational: create re-usable macros for relational declarations
relational.h includes relational macros for defining functions which need to
return 1 for scalar true and -1 for vector true.

I believe that this is the only place that this behavior is required, so the
macro is placed at its lowest useful level (same directory as it is used in).

This also creates re-usable unary/binary declaration and floatn includes which
should simplify relational builtin declarations.

Mostly patterned off of include/math/[binary_decl|unary_decl|floatn].inc
but with required changes for relational functions.

    E.g. If you have clz.cl and clz.ll both specified to be built in the same

    Since the contents of clz.ll were an interface that is implemented in

    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
implementation of the function which casts the second arg to vector before
proceeding.

Tom Stellard 0be3acfc70 libclc: implement initial version of min()
This doesn't handle the integer cases for min(vector, scalar).

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 8c1e72f46a Simplify rotate implementation a bit..
Much more understandable/readable as a result, and probably more efficient.

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.
