It is my understanding that all you need to do is specify let isTarget = 1 in your .td file and it will generate target specific intrinsics. This should allow you to keep the IntrinsicsPTX.td file in the same location.

...es in the PTXIntrinsicInfo class in the back-end? What exactly does isTarget do? It seems to remove a lot of the intrinsic information in the Intrinsics.gen file, but I can't find any documentation on it. > **** > > ** ** > > Micah**** > > ** ** > > *From:* Justin Holewinski [mailto:justin.holewinski at gmail.com] > *Sent:* Monday, December 05, 2011 6:13 AM > *To:* Alberto Magni > *Cc:* Villmow, Micah; LLVM Developers Mailing List > > *Subject:* Re: [LLVMdev] PTX builtin functions.**** > > ** ** > > On Sun, Dec 4, 2011 at 1:10 PM, Alberto Ma...

...agree with this ? Or do you have a better solution. Also I don't know yet how to make llvm recognize the intrinsics defined in lib/Target/PTX/PTXIntrinsics.td, the only other backend that does so is MBlaze. A tentative patch is attached.

...be safer than relying on a client to call llvm_shutdown()? It seems like the whole purpose of llvm_shutdown() is to allow clients to free the data allocated by ManagedStatic instances. Could we not just give them an option, but by default clean up during global destruction? -- Thanks, Justin Holewinski -------------- next part -------------- An HTML attachment was scrubbed...

...A, but I will use PTX as the input of the simulator, gpgpu-sim, so it makes sense. Whether to insert shared memory is depend on the analysis that needs LiveAnalysis, PTX InstrInfo, PTX RegisterInfo, etc. That's why I need to add global variables in MachineFunctionPass.
