This test was added as an aid to debug a particular Khronos test, which
is now fixed, so is being removed.

Khronos_conformance
Merge in fix to sanity test: test kernel.
|
|
|
|
Also, updated CL_DEVICE_LOCAL_MEM_SIZE and Buffer::Buffer() constructor
so that Khrnos basic "prefetch" test can pass.
Previously, it was trying to allocate huge global buffers (computed based
on the LOCAL_MEM_SIZE) and was failing.

new kernel.
The new kernel push back into kernellist at createKernel() function already.

Some Khronos basic tests were crashing with huge work group sizes.
This patch adjusts values down so that Khronos basic tests local_arg_def
and local_kernel_def can now pass.

Buffers in local space, passed as kernel parameters, are allocated at runtime
by shamrock.
This patch ensures such allocated memory is aligned for maximum OpenCL data
type alignment (double16).

Previously, shamrock was not able to get address space attributes from
LLVM's getAddressSpace() API for function (kernel) arguments, as they
didn't exist in the generated LLVM IR.
Now, we use a clang option to force address space mapping, causing
addrspace(<n>) attrs to be inserted.
See the discussion here:
https://www.mail-archive.com/cfe-commits@cs.uiuc.edu/msg76370.html
This was a necessary step to get many of the Khronos basic tests involving
local variables and parameters to not crash.

Redefined nextafter to use __builtin_nextafterf(), and INFINITY to
use __builtin_inff().
This enables the Khronos basic test kernel_limit_constants to pass.

Previously, shamrock was generating load instructions in the kernel stub with
a strict type alignment, which was not being followed by the argument
marshalling code.
This resulted in a NEON vld1 instruction failing in the kernel stub,
and trashing a base register which was not 16 byte aligned.
Now the marshalling code calculates the proper alignement for each argument,
and is based on a buffer aligned to double16 to begin with.
With this patch, all the vector sub-tests of the Khronos basic_parameter_types
test now pass.

Previously, clCreateBuffer() was using malloc to allocate buffers, which
caused havoc with NEON instructions expecting 128 bit alignment for float4
vectors.
Now, use posix_memallign() to ensure alignment meets requirements of largest
OpenCL data type (double16).
Also, update clGetDeviceInfo()'s CL_DEVICE_MEM_BASE_ADDR_ALIGN and
CL_DEVICE_MIN_DATA_TYPE_ALIGN_SIZE accordingly.

based on the contributions from Texas Instruments for Keystone II DSP device:
git.ti.com/opencl
and adding contributions from Linaro for ARM CPU-only support.
