[LLVMdev] [PATCH ]Add Subtarget ptx23
Hi, Justin
PTX version in CUDA 4.0 has changed from 2.2 to 2.3.
I add ptx23 subtarget and update a testcase.
Is that O.K.?
Regards,
chenwj

[LLVMdev] [PATCH ]Add Subtarget ptx23
Hi, Justin
Thansk, but I have a little concern though. I saw Chiou mentioned the
compatibility issue of PTX on the mailing list.
http://lists.cs.uiuc.edu/pipermail/llvmdev/2011-March/038654.html
In my PTX.td patch,
def FeaturePTX23 : SubtargetFeature<"ptx23", "PTXVersion", PTX_VERSION_2_3",
"Use PTX Language Version 2.3",
[FeaturePTX22]>;
I can only guess above statement means PTX23 is fully compatible with
PTX...

Looks good. Committed in r130980. Thanks!
In the future, patches should be sent to llvm-commits instead of llvmdev.

[LLVMdev] PTX backend fatal error
...0] [ID=2]
The command I am using is:
clang kernels/fatal_error_test.cl -O0 -include ocldef.h -include
builtin_functions_ptx.cl
-D__x86_64__
-ccc-host-triple ptx32 -Xclang
-target-feature
-Xclang +ptx23 -Xclang
-target-feature
-Xclang +compute20
Any ideas ?
Best regards

[LLVMdev] Function pointer parameters in PTX backend
Hi everybody,
I am trying to produce ptx code starting from OpenCL C.
I am experiencing a problem concerning pointer parameters.
Here follows an example:
kernel void function(__global float* parameter1) {}
NVIDIA NVCC Compiler:
.entry function(
.param .u32 *.ptr* .global .align 4 function_param_0
)
{
ret;
}
CLANG + LLVM PTX backend
// (skipping builtin functions definitions)
.entry
