Hi, I am passing a data frame and field name to a function. I've figured out how I can create the formula based on the passed in field name, but I'm struggling to create a vector based in that field. for example if I hard code with the actual field name Y = df$Target, everything works fine. but if I use the passed in parameter name, it doesn't give me what I want, Y = df$mytarget

I've started experimenting with winetricks of the late, but I've run into an issue. Where does winetricks install all of it's files, I can't find them in the location I specified or anywhere else....

Hi! I started writing a LLVM backend for a custom architecture. I have some register and instruction .td files and some other files/classes like a MCStreamer for assembler output. At the moment I can compile some empty programs so far. I implemented the method ::eliminateFrameIndex() similar to the Sparc and ARM backend. The method looks like this: // frame pointer is in reg of class

Hi, Is there a way to see what the default argument llc takes from clang/clang++ ? I'm debugging my backend with a very simple c++ program. Running through *clang++ -target myTarget -S simple.cpp -o simple.s * (bug does no show up) gives me different results from *clang++ -target myTarget -S -emit-llvm -o simple.cpp -o simple.ll* *llc simple.ll -o simple.s *(bug shows up) Just trying to

I'm trying to create a simplified 2 slot VLIW from an OR1K. The codebase I'm working with is here <https://github.com/openrisc/llvm-or1k>.

Hello, Given a TargetRegisterClass *RC, I was wondering if there is a way to find out what register class it is directly, instead of comparing it against all the &mytarget::Class1, &mytarget::Class2 etc. This goes back to my original intention of having special query functions for a subset of register classes. Suppose I wanted vector register classes (more than one, say 2-elements and

I try to define a register class def GPR64 : RegisterClass<"mytarget", [i64], 64, [T0, T1.....] to simulate even/odd pair of GPR32 register. Actually, I just use GPR64 as a temporary register. My CPU just support i32 Integer type directly. I use FDR to save f64. def FDR : RegisterClass<"mytarget", [f64], 64,[FD0, FD1, ....] When I move f64 to even/odd pair register, I

Dear Evan Chang: I register incorrect Register class for MVT::f64. I have fixed it. Thanks your advice. "-view-legalize-dags" is very good option. But I don't know why my LLC do not know " -view-legalize-type-dags" option. By the way, I use llvm 2.5 merged from llvm2.4.

Hello. I'm writing a back end for a RISC processor (similar to BPF) with a large SIMD unit. I tried in the last days to make llc compile to SIMD code the following LLVM program: define i32 @foo(i32* %A, i32* %B, i32* %C, i32 %N) #0 { entry: ;vector.body: ; preds = %vector.body, %vector.body.preheader.split.split %0 = getelementptr inbounds i32, i32* %A, i64 0 ; i64 %index ; Alex: I

hi, Dear Evan Cheng: My cpu is i32 embeded CPU. I define pseudo register pair registers. In mytargetRegisterInfo.td: def T0: RegisterWithSubRegs<"t0",[R0,R1]>; ... def GPR64 : RegisterClass<"mytarget", [i64], 64, [T0, T1.....] In mytargetISelLowering.cpp: I define i1, i8 , i16 and i32 are legal. 1. I still have problem. I save my function return double  value in

Ahh, in my scanning through the `ssh_config` manpage, I missed this, and change logs seem to indicate this feature has been around since at least 2017, so should not cause

Hi, I've been reading the docs, including "Creating an LLVM project", and I was wondering if this setup also applies to backends. On one hand it would be good if it did because it would allow one to develop a backend without tracking the LLVM sources with it. If it is not possible (and one follows the instruction of the backend documentation "Writing an LLVM Compiler

Colleagues, R version 2.8.1 in OS X Within a function (which is already within a function), I am sourcing a file. The syntax of the command is something like (this is just an example; the actual code is much more complicated): BIGFUNCTION <- function() { DATAFRAME <- [some commands to create a dataframe] MYFUNCTION(DATAFRAME) } MYFUNCTION <- function(DATAFRAME) { print(ls())

I am trying to open an existing binary file, seek to a position in the middle, and then write one byte, while keeping the already existing data after that byte. It seems to me that I am unable to open a connection to a binary file in both read and write mode. I can open the "r+b" binary file connection and seek around, but I can't write to the file. And looking at the function

Hello, I am using the following code to create ppp files from csv data and map shape files, but I am getting some errors which I have been unable to fix by searching them online: library(spatstat) library(maps) library(maptools) NYC2<-readShapePoly("nybb.shp") # this is a map of the NYC boroughs without waterways and no census tract divisions (but it does include lines separating

A while back I posted about issues with flac files that were not able to be decoded. Here's what I do know: I've ripped most of my collection to my hard drive using KAudioCreator and I've specified that they be stored in flac format. All files play without trouble through Amarok. I found out there was a problem when I had selected files in a playlist and picked "burn"
