Bug ID: 26400
Summary: [CUDA] cannot find matching tex2D
Product: clang
Version: trunk
Hardware: PC
OS: All
Status: NEW
Severity: normal
Priority: P
Component: C++
Assignee: unassignedclangb...@nondot.org
Reporter: wujing...@gmail.com
CC: dgre...@apple.com, llvm-bugs@lists.llvm.org
Classification: Unclassified
texture<float4, 2, cudaReadModeElementType> texA;
__global__ void readTexels(float* d_out) {
float4 v = tex2D(texA, 0.0f, 0.0f);
*d_out = v.x + v.y + v.z + v.w;
}
$ clang++ texture.cu -c --cuda-gpu-arch=sm_35
texture.cu:4:14: error: no matching function for call to 'tex2D'
float4 v = tex2D(texA, 0.0f, 0.0f);

/usr/local/cuda/include/texture_indirect_functions.h:522:39: note: candidate
template ignored: couldn't infer template argument 'T'

float x, float y)

nvcc can compile this file. The declaration of the matching tex2D is in
texture_fetch_functions.h, and its definition is in
texture_fetch_functions.hpp.
