[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
PTX22. Is my guess right? If so, how can one express that Fea...

[LLVMdev] [PTX] Should we keep backward-compatibility of PTX?
Hi Justin,
There are some backward incompatible features of PTX; for example,
special registers are redefined as v4i32 (they were v4i16) in PTX 2.0.
And CUDA 4.0 was rolled out last week. I heard that some instructions
are deprecated.
I am not sure how stable (or unstable) PTX specification is. Do you
have a rough assessment of its stability?
If PTX specification is still fast evolving, I would
