Oh, got it. Thanks for your explain. I misunderstand what getLocation does. If I would like to get the result of alias analysis referring to the stored value, what should I do in llvm?

Yes, in my example, %1 and %2 point to t. %3 points to t2. But t and t2 point to the same var, is it? That's where I'm confused.

So, i'm working through the last of miniscule gvn optimizations, and one of the things that gets tested is whether it will eliminate non-volatile loads in favor of ohter non-volatile loads when there are volatile loads in the way. I.E. define i32 @test1(i32* nocapture %p, i32* nocapture %q) { entry: %x = load i32, i32* %p %0 = load volatile i32, i32* %q %y = load i32, i32* %p %add =

Hi, all, I am planning to add clang-tidy checkers for my company. How to add a new module for my company? Please help, thanks in advance. I try to copy files from cert module, and rename cert to Misra, then add a rule named "m-0-1-1" by ./add_new_checker.py. then I run ninja check-clang-tool, but my case is failed due to below error Running ['clang-tidy',

Hello, I'm getting this in debugger, where 't' is 'Type*': (gdb) p t->isPrimitiveType() $15 = false (gdb) p t->getPrimitiveID() $16 = PointerTyID (gdb) p t->getPrimitiveSize() $17 = 0 There are a couple of things that I'd like to ask. First, if isPrimitiveType() returns false, that the fact that getPrimitiveID returns reasonable value is quite

Hi all, I am implementing a pass which needs aliasanalysis in llvm. My pass firstly records all store or load instructions as follows: loc[cnt++] = AA.getLocation(si/li); Then, get each pairwise alias result. AliasAnalysis::AliasResult ar = AA.alias(loc[i], loc[j]); switch(ar){ case 0,1,2,3;} And the command is: opt -load mypass.so -mypass -basicaa test.bc The store/load in test.bc: (1):

Hey Kevin, Am I correct in assuming that if I want a particular widget to respond to an event which doesn''t take an ID as an argument (like evt_size or evt_left_down), that I have to inherit a new widget and define the event handler within the inherited class? Here''s a little contrived code example to illustrate what I mean: class MyCtrl < Wx::TextCtrl def

Hi, I am trying to set up a C++ library for my R code. I followed the R-extension manual but found out that the example of "X.cpp, X_main.cpp" is somewhat too simple. Here is my code: //lib4R.h testing for interfacing C++ with R -- using C++ library in R #include <iostream> using namespace std; class lib4R { public: lib4R(); ~lib4R(); int

t and t2 are two pointers defined in .c file. The definitions in .bc are: %thd = alloc i64, align 8 %t = alloca i64*, align 8 %t2 = alloca i64*, align 8 .c file likes this: int thd; int *t = &thd; int *t2 = t; On 2/16/15 12:28 PM, Hal Finkel wrote: > ----- Original Message ----- >> From: "Haopeng Liu" <hyliuhp at gmail.com> >> To: llvmdev at cs.uiuc.edu

I have an application where a call-in user is prompted to enter an identification number for schedule information. That id number is setup as an extension, and if that extension doesn't exist, it tells them that they are not scheduled, then loops back to ask for the id number again. My problem is that asterisk pre-emptively goes to the i extension (invalid) too early depending on available

I was reading the code in AliasAnalysis.cpp and happened to notice what looks like a bug. See the line marked by '*' below: AliasAnalysis::ModRefResult AliasAnalysis::getModRefInfo(const VAArgInst *V, const Location &Loc) { // If the va_arg address cannot alias the pointer in question, then the // specified memory cannot be accessed by the va_arg. if (!alias(getLocation(V),

I have downloaded a file that I don't know how to describe correctly. It contains R code and Latex, and I should be able to reproduce an analysis by running an R script in this folder. There is a line in the R script: junk <- system(paste("/usr/texbin/pdflatex ",latexFiles[i1]), intern=TRUE) that needs to be modified to run on my computer. I use WinEdt with

Hello everyone, I am trying to find the alias between a store instruction's pointer operand and function arguments. This is the code, virtual void getAnalysisUsage(AnalysisUsage &AU) const { AU.addRequiredTransitive<AliasAnalysis>(); AU.addPreserved<AliasAnalysis>(); } virtual bool runOnFunction(Function &F) { AliasAnalysis &AA =

It contains the bitcode file(without any optimization) of the below program, void map(int *a) { *a=20; } int main(){ int *a=(int *)malloc(sizeof(int)); *a=15; map(a); return 0; } I want to check if the pointer operand of each store instruction aliases with the function's arguments. I have used below code for this, virtual void getAnalysisUsage(AnalysisUsage &AU) const {

Hi, Yes, that's what I would do. If you want LLVM and the register allocator to also know that the instruction explicitly defines the register, I would designate the register into it's own register class and have your instruction write to that class (and there will be only a single option for RA). cheers, Sam Sam Parker Research Student Electronic Systems Design Group Loughborough

HI, R user, I generate the vectors with the same length. I want to put each vector into each column of data frame. Why it doesnt work`? rm<-data.frame() for(a in 1:6){ rm[,a]<-getmeasure(p1,a,speech) } thanks a lot Tammy _________________________________________________________________ Share your memories online with anyone you want.
