Hello Dmitry, First of all, thank you for your reply. Because of it, I focused in create the lib that helped me. Second, I realize that actually there was one thing different between the machines: due to a more frequent use of the iMac, I have a group of environment variables that are set to my developer folder; and the $PATH is one of those. Furthermore, it seems that my default compiler for

Hi Rasha, First, you should not erase that cloned function XD the idea is that your pass should create that new function, add it to a module (that could be the same one where the original function is, or another one that you could be creating if that is the case), and then just let it be: the pass manager should identify this new function (after your pass returned) and all the other analysis and

Hi Cristianno, Thank you, it works :) with an extra cast:                                     Value *v ......                                     ConstantInt* RR = (ConstantInt *)v;                                     uint64_t VV = (RR->getValue()).getLimitedValue();                                     errs()<<"\nRR  "<<VV<<"\n";

Hi Alexandru, if you have a Value pointer named v, you could use the method v->getValue(). getLimitedValue(), which returns uint64_t, that can be casted as int.

Hello again, So, after some changes, I inserted intentionally values with use in other modules, and I get the following error: While deleting: i1 % Use still stuck around after Def is destroyed: %c = phi i1 [ false, <badref> ] [...] Assertion failed: (use_empty() && "Uses remain when a value is destroyed!"), function ~Value, file

Hello there, I'm writing a transformation pass for LLVM, and I hoped to use dce to clean up the resulting code after my pass. I just have some questions about LLVM's dce implementation. Well, my transformation is a function pass, and, after the changes are made, some instructions are not needed anymore. In order to easily get rid of those instructions, I'm setting all their uses to

Hello again, Thanks for the responses =) Dmitry, I have two points to comment: - First, I applied these two patches, and the .cbe.c file came out ok, except for one little thing -- the global variable was created with both modifiers: static and extern. Then, I just added a single guard to prevent this to happen (in a case of a variable having local linkage, the "extern" part was not

Hi, Depending on what have run before your pass, the loop may have been unrolled or simplified if the computation inside the loop is too simple.

Hello John, What opt command line arguments are you using? If you follow this link<http://llvm.org/docs/Passes.html#no-aa-no-alias-analysis-always-returns-may-alias>, you can see that -no-aa is the default alias analysis implementation if you do not manually specify which AA passes you want to use. Note that you can pass as many different implementations of AA as you want, and each of them

Hi there, I'm having a bit of a problem while trying to create BitCast instructions. Well, first, I have some very generic functions written in C, for which I would like to make calls on another C file I'm playing with using an LLVM Pass. The simplified signature of two of these functions can be seen below: void write(void* data, unsigned b); // write b bytes starting, at address

Hello there, I'm trying to use a simple implementation of a queue (my own implementation of it, actually), and I'm trying to use the functions defined on my queue class inside some llvm-ir code. Unfortunately, the names of the functions are being messed up, then I created some function wrappers just to avoid having to deal with the C++ weird function renaming. So, to easily wrapper the

Oh, ok, sorry but only now I understood your list will be used by the programmers functions on his code, and not on your pass code for llvm while your pass is being compiled XD Ok, once I had a similar problem, and I resolved it by creating a mini API in C++ with some classes that encapsulated lists of integer, floating point or pointer types (I actually needed three different classes for those

Hello again, First of all, thanks for all the answers =) they really helped a lot =D *Have you verified that some other pass is not adding the function declarations back in after your pass is executed (e.g., by using the -debug-pass=Executions argument to see what passes run after your pass)?* I considered that for a moment, but I realized that wouldn't be possible for two reasons: I

The code looks like this: PassManager pm; MyAlias * aa = new MyAlias(); pm.add(aa); pm.add(new MyAliasUsingPass()); Both MyAlias and MyAliasUsingPass are now ModulePass'es. MyAlias is an alias

Hello guys, So, I'm stucked in a problem involving a Function and a derived class. Well, I was refactoring part of my pass code, and created two classes in this process that are interesting here: class A and class B. Class B inherits from class A; on the other hand, class A has some pure virtual methods (already implemented in class B), and a Module, that holds only one auxiliary function (a
