similar to: [LLVMdev] is there any passes or compiling options that can aviod to generate vector instructions and 'select' instruction in IR

hi Sam: thank you for your reply. but i have another question about this 'select' instruction. i think that in LLVM IR, i can use a branch and two seperate assignments to replace 'select' instruction(am i right?). so is there any compiling option to aviod generate 'select' instruction? -- View this message in context:

Hi Dong, try turning optimizations on. I get the select then: > └─[$]› echo 'int min(int a, int b) { return a < b ? a : b; }' | clang -xc -O1 -S -emit-llvm -o - - > ; ModuleID = '-' > target datalayout = "e-p:64:64:64-i1:8:8-i8:8:8-i16:16:16-i32:32:32-i64:64:64-f32:32:32-f64:64:64-v64:64:64-v128:128:128-a0:0:64-s0:64:64-f80:128:128-n8:16:32:64-S128" >

Hi, If you run the simplify-cfg pass, select instructions should get generated.

Have 4 harddrives hde,hdg etc all of these drives are mounted in samba. When i copy file from one drive to another i notice that server sends the file to my computer and then back to itself (into the right place). The file will be copied but doing so it will eat half of my network bandwith. Is it possible to aviod this? Best Regards Patrick Betfjord

I'm experiencing some weird printing problems with samba connected printers. When I'll bring up a 95/98 workstation, sometimes it will say that the printer is offline, when it clearly isn't, or it will see everything fine, but it simply won't print. These are remote lpd connected printer to the samba server, and lpd can print fine. These are JetDirect HP printers. Any

I have read in several places that one should attempt to avoid for loops whenever possible. In this spirit, I was playing with some code that I have written to improve its efficiency and elegance. The following iteratively drops a column from a data frame and applies a function to the reminaing columns. I replaced this for loop: for (y in 1:dim(x)[2]) my.function (x[,-y]) with this:

I have a data.frame with ~250 observations (rows) in each of ~50 categories (columns). I would like to perform t.tests on subsets of observations within each column, with the subsets according to index vectors contained in other columns of the data.frame. My data.frame looks something like this: x<-data.frame(matrix(rnorm(200,mean=5,sd=.5),nrow=20)) colnames(x)<-c("site",

hi, Duncan, thank you for your reply; instruction "i->getOperand(0)->dump()" may print the %4 in the screen, but how can i store it in a variable like char * oprand="%4" ? -- View this message in context: http://llvm.1065342.n5.nabble.com/get-the-identifies-of-the-unnamed-temporaries-from-the-instruction-of-LLVM-IR-tp56572p56588.html Sent from the LLVM - Dev mailing

Hello all, I just noticed that LLVM has trouble recognizing nested simple select operations. My testcase is as follows: -------------------------- snip ------------------------------ #include <stdio.h> int main(int argc, char **argv) { int a; scanf("%d", &a); a = a > 255 ? 255 : a < 0 ? 0 : a; printf("A: %d\n", a); return 0; }

Hi, I have stacked Bar graph which has about 20-30 items. I have to name each of these items. But there names/labels are overlapping. Is there any option to make the labels display vertical instead of horizontal? Any other ideas how can I aviod this overlapping? Please suggest. Thanks -- Posted via http://www.ruby-forum.com/.

Something like this should do the job (taken from a test file from the libbeauty decompiler project): /* A very simple jump table. */ int test58(int var1) { int n = 0; switch (var1) { case 1: n = 1; break; case 2: n = 2; break; case 3: n = 3; break; case

Hi again, It is probably me doing something wrong, but I have attached a trimmed down sample that shows the issue and the output that Clang 8.0.0 makes (using the binary release from llvm.org). I invoke clang as follows: clang -S -O3 -o Evergrowing.s -Wall Evergrowing.ll I tried using -O1, -O2, and -O3, but all where the same. Please notice that I renamed 'main()' to

Hello, As is known to all, there is a relationship between program's instructions and its execution time. In other words, we can estimate the execution time based on the number of program instructions. I'm curious about what the relationship between IR instruction and execution time. I know the number of program instructions and the execution time is highly related to the platform and

Dear R-users, I intend to do a spatial analysis on the genetic structuring within a population. For this I had thought to prepare a kernel density estimate map showing the spatial distribution of individuals, while incorporating the genetic distances among individuals. I have a dataset of locations of N unique individuals (XY-coordinates) and an NxN matrix with the genetic distances given as a
