Hi All, My target has 32bit registers, but it has some 64bit instructions which are using pairs of these 32bit registers. I have defined registers, aliases and subregister set. The problem is that register allocator is using 32bit registers that are already used in a pair, for example: lw $r0, 16[$r12] // load word to r0 ld $p0, 36[$r12] // load doubleword to p0 shl $p0, $p0, $r0 // shift

For compile and link Basicmath files (using shell script): llvm-gcc -emit-llvm basicmath_small.c -c -o basicmath_small.bc llvm-gcc -emit-llvm cubic.c -c -o cubic.bc llvm-gcc -emit-llvm isqrt.c -c -o isqrt.bc llvm-gcc -emit-llvm rad2deg.c -c -o rad2deg.bc llvm-link basicmath_small.bc cubic.bc isqrt.bc rad2deg.bc -o basicmath.bc

I believe we'd need LLVMBuild.txt even in autoconf build - for bunch of autogenerated stuff, e.g. list of all asmprinters / asmparsers / InitializeAllTargetInfos, etc., since targets are not autoregistered anymore.

What assembler are people using with the SystemZ backend? I am trying to assemble the output of the SystemZ backend with the GNU binutils assembler (build with --target=s390x-linux). I get errors when assembling instructions with literals that are negatives. For example, the test case test/CodeGen/SystemZ/01-RetImm.ll gives errors: $ s390x-as 01-RetImm.s 01-RetImm.s: Assembler messages:

Thanks for the reply. The LoopInfo pass can actually identify the loop I mentioned. My former question is due to a bug in my pass. What I worried is that LoopInfo can not identify all the natural loops for the benchmarks I use, but now I haven't found any such cases.

Ok.

Hello, I'd like to propose the addition of a new SystemZ backend to the LLVM and Clang code base. We're interested in this for the same reason we've been interested in the PowerPC back-end recently: to enable packages in upcoming enterprise Linux distributions that need LLVM support (e.g. 3D desktop support via llvmpipe). Now, I understand that a SystemZ backend used to be part of

I assume the newer one is better, but you can look at both, shouldn't take too long.

Hello, If I have two variables that are factors or characters and I want to create a new variable that is the combination of both what function can I use to accomplish this? Ex.

Hello everyone, I have a large dataset (x) with some rows that have duplicate variables that I would like to remove. I find which rows are the duplicates with X1<-which(duplicated(x)). That gives me the rows with duplicated variables. Now, how can I remove just those rose from the original data frame. I think I can create a new data frame without the duplicates using subset. I have tried:

Hi All, If you could help me with this problem I would greatly appreciate it. Suppose I have a matrix A: 1 1 1 1 0 1 1 1 1 1 1 1 0 1 0 1 0 0 1 0 1 0 0 1 0 0 0 1 1 0 0 0 0 1 0 0 I would like, for each row, to sum the number of times a 0 appears in front of a 1. So what I would like is to have Sum 1 1 1 1 0 1 1 1 1 1 1 1 1 0 1 0 1 0 0 2 1 0 1 0 0 1 0 0 0 2 1 1 0 0 0 0 1

Does anyone know how to accomplish this? Thanks in advance Cameron Guenther, Ph.D.

I am trying to great a new column of effort data from an existing vector of gears used. It is a simple code where effort[Gear==300]=(DIST_TOW*7412) effort[Gear==301]=(DIST_TOW*7412) The code appears to work for some of the data but fails for others and inserts a NA value I also get this warning message Warning message: number of items to replace is not a multiple of replacement length Can

Hi, all: Now I'm working on writing a backend for Moto MCore, but I don't know how to describe some instructions. First, I've already written MCoreRegisterInfo.td like these: class MCoreReg<bits<4> num, string name> : Register<name> { let Namespace = "MCore"; field bits<4> Num = num; } def R0 : MCoreReg< 0, "R0">,

Do you need the isel support for them? If yes, then you should custom isel them. iirc ARM and SystemZ backends have similar instructions, while only the first one supports full isel for them. In
