Hi all, As of r232885 I've removed the argument-less TargetMachine::getSubtarget and TargetMachine::getSubtargetImpl. For the targets that aren't completely independent of this I've gone ahead and left a non-virtual version of the function in the target specific TargetMachine. What this means in practice is that those targets can only use a bare getSubtarget call in the...

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

...f TargetLowering::isNoopAddrSpaceCast(SrcAS, DestAS) returns true. In this case the MCExpr for the addrspacecast is the MCExpr of its first operand. It seems hard to obtain an instance of TargetLowering in AsmPrinter::lowerConstant(). Other methods in this class obtain it by calling `MF->getSubtarget().getTargetLowering()`. However, because MF is nullptr when lowering initializers of global variables, it won't work. My impression is that this is not possible because every function has its own TargetLowering instance. Is that correct? NVPTX solves the problem by having a method on it&...

...mpilers.llvm.devel/80456 The command line options I'm currently looking into are "-target-cpu" and "-target-feature" and I would like to get feedback about the approach I've taken (patches attached). The attached patches make the following changes: - In TargetMachine::getSubtarget(const Function*) and MachineFunction's constructor, use per-function subtarget object instead of TargetMachine's (module-level) subtarget object. This allows passes like selection dag to switch the target on a per-function basis. - Define class TargetOptions::Option, which records whether...

...basis d) Use them in TTI and various other backend hooks rather than any code gen specific ones. Simple right? :) I'm happy to elaborate here, but I believe the work is relatively straight forward if a lot of typing. Every step there is likely to be a lot more complicated, but similar to the getSubtarget<>/getSubtargetImpl changes it should be very easy to do on any particular backend and fan out support there. Just make sure that clang knows which targets do and don't support the flag. Happy to help or review work here. Thanks! -eric -------------- next part -------------- An HTML att...

What's the purpose of the TargetSubtarget class? It appears the only users of getSubtarget are in the target-specific code, where the abstraction is superfluous. Is it just a way to encourage targets to follow a nice pattern of keeping subtarget state in a separate class, or are there grand plans? Dan -- Dan Gohman, Cray Inc.

Here's an example of the output in a Mesa client with a corresponding patch and RADEON_DUMP_SHADERS set: Shader Disassembly: S_WQM_B64 EXEC, EXEC ; BEFE0A7E S_MOV_B32 M0, SGPR6 ; BEFC0306
