similar to: [LLVMdev] How to detect all free() calls

if you don't include stdlib.h, where free() is declared, you'll simply get a default C function signature: int free(...); On Mon, Mar 11, 2013 at 1:56 AM, Jane <270611649 at qq.com> wrote: > Thanks. isFreeCall() works well but for > %call2 = call i32 bitcast (i32 (...)* @free to i32 (i8*)*)(i8* %call1) > nounwind, !dbg !16 > So I tried to figure out when the above

Hi, I'm trying to write a pass to detect all free()/delete() call instructions in LLVM IR.The method is as follows. First I find Call Instructions: CallInst *CI=dyn_cast<CallInst>(&*i); then see if the Function name matches: name=CI->getCalledFunction()->getName(); if(name=="_ZdlPv"||name=="_ZdaPv"||name=="free")

I'm trying to create a language structure that is a call to a function with a number of arguments that is only known at run time. I do this by using repeated indices to expand out a call with a single argument. However, when I change one of the arguments, all are changed. I don't see the same behavior when I initially create a call with multiple arguments. Even more strangely,

Hi! I want to know the way that calls are answer in this case... I have queue1 and queue2, one agent that receive call from both queues. queue1 <- call1 queue1 <- call2 queue2 <- call3 queue2 <- call4 In my test the agent answer calls in this order: call1,call3,call2 and call4. I think this must be in this order call1,call2, call3, call4 like a big FIFO. Its ok this behavior? Could

Hi, I want to edit LLVM generated IR file, like as given below, Original LLVM IR file, @.str2 = private unnamed_addr constant [17 x i8] c"\0AI am in one_11\0A\00", align 1 ; Function Attrs: nounwind define i32 @one_1(i32 %ivar1, i32 %ivar2) #0 { entry: %ivar1.addr = alloca i32, align 4 %ivar2.addr = alloca i32, align 4 %isum = alloca i32, align 4 store i32 %ivar1, i32*

Hi, I want to call/add some functions(that defined in another file) on top of some functions, and reflect the same changes in object file. No, I am not looking for contractor.

Hi, Yes I am looking for IR pass that will do insert call of functions that defined in another file. Links/suggestions that guide me to start for adding IR pass will help me so much.

I''m having a problem with multiple Ajax.Updater instances. I have five small chunks of data being loaded into my homepage, and they seem to be firing off one at a time. So the pieces load up in the order they were called. Maybe I''m being a noob, but shouldn''t all those requests just fire away and then place the content as it gets received? I was doing multiple versions,

Hi, My requirement is something like as given below, a.c => a.obj contains a1() and a2() function b.c => b.obj contains b1() and b2() function main.c => main.obj call to a1, a2, b1, b2 Now, I want to move a1(), a2() from a.obj to b2.obj and on top of function b1() When I call b1() from main, it should call first a1, a2 and then function definition of b1 Can you please give me some

I am working with some survival data with missing values. I am using the mice package to do multiple imputation. I have found code in this thread which handles pooling of the MI results: https://stat.ethz.ch/pipermail/r-help/2007-May/132180.html Now I would like to plot a survival curve using the pooled results. Here is a reproducible example: require(survival) require(mice) set.seed(2) dt

Hi I am using LLVM to help me do some code analysis. I wrote a LLVM Function Pass to help me to generate some information. I use the code below to get the source line information for every instruction. for (BasicBlock &BB : F){ for(Instruction &I: BB){ DILocation* Loc = I.getDebugLoc().get(); unsigned Line = Loc->getLine() } } I think the function's first

Hi David Thank you very much for your suggestions. ScopeLine works well. It could represent the start of a function. Do you know whether I can get the start column of this function?

Hi, Again, sorry for the length of this post. Once I get my new office I will get a website set up on my work machine and will simply post a link to the log since I doubt many people are truly interested in these logs. To further analyze what is happening, I added my own routine in main.c called DEBUG_SET_NAMED and then redefined the SET_NAMED macro to use it and then rebuilt R. I

Hi All, Well I finally have found the time to get svn working and I have successfully built my own tuned atlas (multi-threaded version) libs and have both the r-devel and r-patched trees building daily on my box. The problem is I still do not have a good idea of the layout and design of R, and typically I "learn by doing" by trying to fix a bug that hits me. Unfortunately ;-)

Awesome, thanks! Now I have another question. I have a matrix multiplication code. This is my code: #include <stdio.h> #include <stdlib.h> #define n 4 int main(int argc, char *argv[]) { int i, j, k; int A[n][n], B[n][n], C[n][n]; for(i=0;i<n;i++){ for(j=0;j<n;j++){ A[i][j] = 1; B[i][j] = 2; C[i][j] = 0; } }

This is my example (for.c): #include <stdio.h> int add(int a, int b) { return a + b; } int main() { int a, b, c, d; a = 5; b = 15; c = add(a, b); d = 0; for(int i=0;i<16;i++) d = add(c, d); } I run: $ clang -O0 -Xclang -disable-O0-optnone -emit-llvm for.c -S -o forO0.ll $ opt -O0 -S --loop-unroll --unroll-count=4 -view-cfg forO0.ll -o for-opt00-unroll4.ll

Guys, on second thought... doesn't making the exception registers live from the InvokeInst to the LandingpadInst create problems for critical-edge-splitting ? if a landingpad-edge is critical and needs to be split, won't we be creating and inserting a new BB between the "invoke-block" and the "landingpad-block", and if we do then isn't there the

R-helpers: I have a dataset that has 168 subjects and 12 variables. Some of the variables have missing data and I want to use the multiple imputation capabilities of the "mice" package to address the missing data. Given that mice only supports linear models and generalized linear models (via the lm.mids and glm.mids functions) and that I need to fit Cox models, I followed the previous
