Hello, I came across the file *omega.cc* which is in directory* xapain-application/omega/* In this file , atoi is used in *Percentage Relevance cutoff *(293 line no) as Percentage lies between 0-100 their is no need to modify atoi . But do we need to check for error's ? Second Implementation is in *collapsing* (301) in which we collapse set of document under a key,range of this key has not been define...

Hello, I am working on replacing atoi () and atol() functions with strtol() and strtoul() . I came across many files which uses statement like these time_t secs= atoi(data_span.c_str()), here time_t Datatype is not known but wikipedia says that it is integer so is it necessary to replace atoi with strtol over here ?? And is their an...

Hello , I came across this function *HtmlParser::decode_entities(string &s)* in *xapian-application/omega/htmlparse.cc* which basically does is extract hex value if any or extract number.For extracting number atoi is used and value returned by it is stored in variable "val" , I think so replacing atoi with strtoul would be useful here as number can have larger value although the variable "val" is unsigned int so i need to change the that definition of "val" also. Is that ok to d...

Hello I compiled the following program using the web interface #include <stdio.h> #include <stdlib.h> int main(int argc, char **argv) { int a; int b; int c; int d; int X = 10; a = 777; b = a | (atoi(argv[1])); c = b | (atoi(argv[2])); a = c | (atoi(argv[4])); b = a | (atoi(argv[5])); d = b | (atoi(argv[6])); a = d | (atoi(argv[7])); b = a | (atoi(argv[8])); c = b | (atoi(argv[9])); if (c) { X = 2000; } printf("%d\n", X); return 0; } It is easy to see that t...

Ok. I have managed to vectorize the second loop in the following code. But the first loop is still not vectorized? Why? int main(int argc, char** argv) { int a[1000], b[1000], c[1000]; int g=0; int aa=atoi(argv[1]), bb=atoi(argv[2]); for (int i=0; i<1000; i++) { a[i]=aa+i, b[i]=bb+i;} for (int i=0; i<1000; i++) { c[i]=a[i] + b[i]; g+=c[i]; } printf("sum: %d\n", g); return 0; } When i executed the optimized IR through jit (lli sum-vec03.ll 5 2) i am getting following error: #0...

...side the loop so it doesn't need to exist. So the compiler turned your loop body back into g+= aa + bb; And since the loop is 1000 iterations and aa and bb never change this got further simplified to (aa+bb)*1000. int main(int argc, char** argv) { int a[1000], b[1000], c[1000]; int g=0; int aa=atoi(argv[1]), bb=atoi(argv[2]); for (int i=0; i<1000; i++) { a[i]=aa, b[i]=bb; c[i]=a[i] + b[i]; g+=c[i]; } ~Craig On Thu, Aug 17, 2017 at 11:37 AM, hameeza ahmed <hahmed2305 at gmail.com> wrote: > why is it happening? is there any way to solve this? > > On Thu, Aug 17, 2017 at 10...

I want to vectorize the user given inputs. when opt does vectorization user supplied inputs (from a text file) will be added using AVX vector instructions. as you pointed; When i changed my code to following: int main(int argc, char** argv) { int a[1000], b[1000], c[1000]; int aa=atoi(argv[1]), bb=atoi(argv[2]); for (int i=0; i<1000; i++) { a[i]=aa, b[i]=bb; c[i]=a[i] + b[i]; printf("sum: %d\n", c[i]); } I am getting error remark: <unknown>:0:0: loop not vectorized: call instruction cannot be vectorized. I am running following commands: clang -S -emit-llv...

even if i make my code as follows: vectorized instructions not get emitted. What to do? int main(int argc, char** argv) { int a[1000], b[1000], c[1000]; int g=0; int aa=atoi(argv[1]), bb=atoi(argv[2]); for (int i=0; i<1000; i++) { a[i]=aa, b[i]=bb; c[i]=a[i] + b[i]; g+=c[i]; } printf("sum: %d\n", g); return 0; } On Thu, Aug 17, 2017 at 10:03 PM, Craig Topper <craig.topper at gmail.com> wrote: > Did you remove the printf completely?

Hello, I have a problem of generating a load instruction. The LLVM bytecode is: ------------------------ entry: ... %2 = call i32 (...)* @atoi(i8*%1) nounwind /*<- Insertpos*/ ... -- bb1: .. %5 = icmp sgt i32 %2, %i.0 ... ----------------- Now I have pb: pointer to the Value object of *%2* of bb1. Here, I want to generate a load instruction and I did it as: new LoadInst(pb, "load_2", InsertPos); where InsertPos po...

...nfigure checks and then install it to an architecture-dependent path. But anyway, there's no "strtou()" so you have to converting to unsigned long with strtoul() and then check for potential overflow from the cast to Xapian::valueno. > I think you?ve been looking at other uses of atoi/atol; if you?ve > successfully updated code then you should make a pull request or email > a patch (or attach one to the trac ticket) so someone can review it > and get it into trunk (and hence into a future release).

Because what is happening is that if function “atoi” gets cloned I don’t have a definition of “atoi_parallel” therefore I get undefined references when linking. I just want to clone and instrument functions implemented in modules of my program. > On Nov 19, 2016, at 13:54, Mehdi Amini <mehdi.amini at apple.com> wrote: > > >>...

...same function but with a different name, i.e. sum() and sum_parallel(). After my pass I will run ThreadSanitizer instrumentation pass only on the new copy of the functions, i.e. only the “_parallel” functions will be instrumented by tsan. In some programs that I am compiling, the functions such as atoi and atof get cloned but I want to avoid this, and I noticed that only those functions have GlobalValue::AvailableExternallyLinkage, so I was wondering if checking the linkage is enough to avoid those library functions or there could be situations of functions with that linkage but that have the bo...
