I have added new instructions to my target, unfortunately they are not being properly type legalized. The instructions I've added are a vector add, vector load and a vector store. Can anyone lend a hand on how to legalize them so that my target would be able to recognize them. Below is the output of llc with a -debug-only=isel. As you could see the output type for load, store, and add changes

Hi all I didn't find anything relevant in the archives about this so I wanted to ask here. I am generating a simple function for JIT using the API. The function structure and code work fine with 2.8 but give me "Cannot select" with 2.9. Assembly dump of the function: define double @0(double %f0, double %f1, double %f2, double %f3, double %f4, double %f5, double %f6, double %f7,

Hi there, I'm having a hard time with promoting operands from i1 to i32 in my backend... I have to register classes, VTs are i1 and i32. The i1 registers are only for predication and conditional jumps, so I want to use them with brcond, setcc. There are no instructions to directly load a value in an i1 register or to copy between i1 and i32, so I need the DAG Legalizing Pass to not generate

Hi there, I am currently trying to create an LLVM Backend for a RISC architecture and running into problems with setCC and brcond. First a few explanations: The architecture doesn't have a dedicated flag register, but seven 1-bit-wide so called "condition registers", c0-c6, which can be set by e.g. a compare instruction: > cmp ne, c0, r1, 123 It also supports conditional

    Thank you Kevin!!!    If I use fptrunc and bitcast realise NEON vcvtt ( I can sure, "fptrunc  double %tmp to float" is right, but "fptrunc float %tmp to half" is wrong). My target platform is MIPS.  The command as following: NEON:            vcvtt.f16.f32 s2, s0 llvm Code: %Vt_2 = load float* %VFP_s0, align 4 %Vt3_1 = fptrunc float %Vt_2 to half %Vt4_1 = bitcast half

Dear forum, I would like to forecast e.g. with the arima-model. To figure out which model works best I am going to predict with this models. my first code: for(ar.ord in 1:3){ for(ma.ord in 1:3){ print(predict(arima(para_qtr[1:(n-8),1],order=c(ar.ord,1,ma.ord)), n.ahead=8)$pred) } } this one works. but I want to "save" my results in a matrix or a data.frame. my second code:

hi justn, I have a llvm ir file which is generated by my own code generator. When I run *llc -march=ptx64 ./gpu_kernel.ll * on it, the following error was given LLVM ERROR: Cannot select: 0x269a7a0: ch = store 0x2666370, 0x2697760, 0x269a2a0, 0x2698d90<ST4[%p_arrayidx5], trunc to i32> [ID=20] 0x2697760: i64 = add 0x2699ea0, 0x2699590 [ORD=23] [ID=16] 0x2699ea0: i64 = shl 0x2699fa0,

Hi all, This is Linfeng Zhang from Google. I'll work on ARM NEON optimization in the next few months. I'm submitting 2 patches in the following couple of emails, which have the new created celt_fir_neon(). I revised celt_fir_c() to not pass in argument "mem" in Patch 1. If there are concerns to this change, please let me know. Many thanks to your comments. Linfeng Zhang

Hi Daniel,    Thank you your replying.     Yes, the problem is about MIPS backend. You give me this message "There is limited support for the <8 x f16> type when MSA (MIPS SIMD Architecture) is enabled but even then scalar half-precision is not currently supported."  Could you give me some official link or some evidence? Thank you very much. Robin yalong at multicorewareinc.com

I'm trying to figure out how to interpret DAG output that is shown below. If I were to draw it by hand, how would I do it? I tried to do it, but unfortunately I can't figure it out. I know there is a way to generate a graph, but I made some changes to my backend which hangs clang/llc. Would someone be kind enough to give a picture of what of a graph below? I'm sure once I see one I

Hi everyone, I have the following code (as part of a larger function): %0 = icmp eq i16 %a, 0 ; <i1> [#uses=1] br i1 %0, label %bb1, label %bb I would like to match this with a BRCOND, but all I get is an error message when compiling the above code that say: LLVM ERROR: Cannot yet select: 0x170f200: ch = br_cc 0x170f000, 0x170ed00, 0x170dc60, 0x170ec00, 0x170ef00 [ID=19]

Dear all, I am still a R apprentice... Apologies for the basic question. I am trying to reshape a dataframe based on the order of two variables (a character variable and a numerical variable). To simplify it, consider the following dataframe > df<-data.frame(id=c("b","b","a","a","a"),ord=c(2,1,1,3,2)) id ord 1 b 2 2 b 1 3 a 1 4

I'm trying to create a TableGen pattern to match extract_vector_elt. My pattern looks like this: (set i32:$dest, (extract_vector_elt v16i32:$src, i32:$index)) However, when I compile, I get an error: error: Variable not defined: 'extract_vector_elt' However, if I omit the rule and attempt to compile something that uses this functionality with clang, I get this error, which
