Hi, I have a list of mutations, called "mutList", of the form: > head(mutList) Alu 1 AluJ 2 AluJ/F(R)AM 3 AluJ/FLAM 4 AluJ/FRAM 5 AluJ/monomer 6 AluJb It contains about 500 elements and not all of them contain the sequence "Alu". I tried using this code: Alu<-mutList[which(grep("Alu",mutList)==1)] But that simply returned all of th...

Hello, I have one question about the ALU scheduler.

In BPF, an ADD instruction is defined as a 2 register instruction: 0x0f. add dst, src. dst += src In BPFInstrInfo.td this kind of ALU instruction is defined with: def _rr : ALU_RR<BPF_ALU64, Opc, (outs GPR:$dst), (ins GPR:$src2, GPR:$src), "$dst "#OpcodeStr#" $src", [(set GPR:$dst, (OpNode i64:$src2, i64:$src))]>; How d...

...interested in writing my own backend. I'm also developing the target architecture (maybe to go in an fpga eventually) and I'm intentionally making it extremely simple. I think of it as a narrow microcode, because (for example) performing an add requires a sequence of instructions like: set aluin1 = r1 set aluin2 = r2 aluop add set r3 = aluout I've started implementing the backend in clang, and I got this basic example working by modifying my backend's implementation of SelectionDAGISel::Select to handle ISD::ADD and transform it into the above 4-instruction sequence. However, I&...

...We already support -mfpmath=vfp/neon in Clang, but it's bogus. My proposal is to make it count. The best way I can think of is to let -mfpmath=vfp *disable* only FP NEON and -mfpmath=neon *enable* only FP NEON, both orthogonal from integer math. Examples: Works today: -mfpu=soft -> Int (ALU), FP (LIB), no VFP/NEON instructions -mfpu=softfp -> Int (ALU), FP (LIB), VFP/NEON instructions allowed -mfpu=vfp -> Int (ALU), FP (VFP) -mfpu=neon -> Int (NEON), FP (NEON) Change proposed: -mfpmath=neon -mfpu=vfp -> Int (ALU), FP (NEON) -mfpmath=vfp -mfpu=neon -> Int (NEON), FP (VF...

From: Peter Arremann <loony at loonybin.org> > Compiles aren't a great benchmark for a box since its 100% cpu and > neglects memory or disk performance but I had the numbers handy > for that :-) BTW, it is 100% ALU and a major strain on the ALU LOAD. In other words, it's not a good benchmark for even CPU. That's why the 3-issue ALU in the Nx586 on-ward blows the 2-issue ALU in PPro on-ward (especially the P4) to crap. But that's all besides the point because it has _0_ to do with server performa...

I think you will find it is more complicated than that. A 'mov' usually doesn't need an ALU resource.

...:* llvmdev at cs.uiuc.edu *Subject:* [LLVMdev] DFAPacketizer Hi, I am having problems writing the ProcessorItineraries list. As instructions on my VLIW target have varying size I want to model both cpu units and bundle bits as FUs. The following does not work, to my surprise: InstrItinData<ALU, [InstrStage<1, [BITS1,BITS2, BITS3, BITS4], 0>, InstrStage<1, [ALU1, ALU2]>]> I want to express that there are two ALU's, and four bundle slots, and in this case while allocating this type of instructions several times, I would like to be allowed only two such instructions p...

...te that floating-point operations are **not** generated by GCC's auto-vectorization pass **unless** -funsafe-math-optimizations is also specified. This is because NEON hardware does not fully implement the IEEE 754 standard for floating-point arithmetic (in particular denormal values are treated as zero), so the use of NEON instructions may lead to a loss of precision. That is to say, GCC will only auto-vectorize floationg-point arithmetic if both -mfpu=neon AND -funsafe-math-optimizations are given. -mfpu=neon by itself does not imply that it is OK for GCC to genera...
