Hello all, I am instrumenting the code such that I write the results of some instructions to file. As you can see below, I am writing the results of add instruction to the file. The IR generated for writeToFile is also posted below. My problem is that it is writing to the file in format bytes and it is not human-readable. How do I make it write human readable strings to the file? define i32 @add(i32 %a, i32 %b) nounwind { entry: %tmp3 = add i32 %b, %a ; <i32> [#uses=2] alloca i32 ; <i32*&g...

...ommunity and have been playing with the program for about a month. Last week I switched my operating system to Tiger (Mac OS 10.4). Since then (I think) I have been unable to save scripts and get a message as follows in the R console: 2005-06-01 15:27:10.152 R[203] *** -[NSBigMutableString writeToFile:options:error:]: selector not recognized [self = 0x6843d30] 2005-06-01 15:27:10.174 R[203] *** NSTimer discarding exception '*** - [NSBigMutableString writeToFile:options:error:]: selector not recognized [self = 0x6843d30]' that raised during firing of timer with target 11cc230 and sel...

Hi, I am writing an optimization pass where I need to instrument the code such that I need to store the results of some instructions in file. Using llc -march=cpp option I figured out how to add a function(say writeToFile) which takes char* parameter and writes to file. Now, I need put in a CallInst which calls writeToFile passing the Instruction result as parameter. How do I do this? So, in my optimization pass... Func *myprint = makewriteToFile() //creates a function which writes to file for (Function::iterator...

ok 1 last question for the day... I created a function in C. void writeToFile(char *str) { FILE *f; if((f=fopen("example","a"))==NULL){ printf("could not open file"); } else{ fprintf(f,str); fclose(f);} } used this to create .bc then using llc -march=cpp I got the cpp code to create this function. While instrumenting my code, I place ca...

I basically need to store the results of some instructions in a file. If you're confused about how the IR works, http://llvm.org/demo/ can be useful. The question you're asking doesn't really seem to make sense. -Eli

Thanks! How do I cast the result to a string? I basically need to store the results of some instructions in a file.

First off, thanks -- this is a pretty great library and it feels like I'm learning a lot. I'm getting some more experience with libfuzzer and finding that I have a couple of questions: - How does libfuzzer decide to write a new test file? What distinguishes this one from all the other cases for which new test inputs were not written? Must be something about the path taken through the
