...custom LLVM intrinsics, and is built around pure C macros. Clover uses a slightly more complex system, involving a Python script "compiling" a set of built-ins into four files. For example, this declaration (REPL is a macro that does a simple for()) : ---- def vecf : float2 float3 float4 float8 float16 native $type acospi $vecf : x:$type     REPL($vecdim)         result[i] = std::acos(x[i]) / M_PI; end ---- Is compiled to these fragments, one for each vector type (float2, float3, etc) : ---- // In stdlib_def.h : what the OpenCL C kernel sees float2 OVERLOAD acospi(float2 x); // In std...

Hello, Does anyone know a way to connect from R on Linux box to TeraData server? I can use ODBC connection on Windows box, but with amount of data I need (and prefer) to use large Linux box. Thanks, Vadim

...requires a sequence of extracting each element in the vector and inserting each element into a new vector. With this new form, it is more straightforward to write and reason about typedef __attribute__(( ext_vector_type(4) )) float float4; typedef __attribute__(( ext_vector_type(8) )) float float8; float8 f8; float4 f4a, f4b, f4c; f4a = f8.hi; f8.hi = f4b; f8.lo = f4c; where hi and lo represent the high half and low half of the vector. The outgoing IR is %f4a = shufflevector <8xf32>%f8, undef, <4xi32> <0, 1, 2, 3> %f8 = shufflevector <4xf32>%f4b, <4xf32&g...

...s test (piglit generated_tests/cl/builtin/math/builtin-float-cos-1.0.generated.c) I have been seeing random failures (incorrect results) for some time and tried to investigate. the weird part is that the failures are not 100% reproducible, sometimes the tests pass, or partly pass (it's usually float8 and float16 subtests that fail). Failure is always the same "Expecting -0.925879 (0xbf6d0668) with tolerance 0.000000 (2 ulps), but got nan (0x7fc00000)" although the position may vary. even if the same value was computed earlier in the results array The first patch of this series does n...

AMD would like to add new functionality to ranlib (and later ar and nm) and to the bits of LLVM Core that read (and later write) archives. Herewith a terse summary of the change, which we want to improve support of OpenCL for multiple GPUs in a single run-time. Conceptually, a serialized archive is really 2 pieces: a few header members and a set of normal file members. There are no constraints on
