...ables. To show the effect of the pass i need to show that I deleted the variables that originally appear in the user code, not temporary variables added by llvm.

what about the memory address of e and f? can i get them?

Hi, I need to check if a variable belongs to the program originally. Consider the following code line: y = x + 4 and its corresponding llvm ir (roughly): %16 = load i32 %x %add = add i32 %16, i32 4 store i32 %add, %y I need to distinguish between %16, %add and %x, %y. Any help is appreciated. Best, Mohammad -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hi all, How can i find the instruction that uses the result of a load instruction. For example: %16 = load i32, i32* %ptr %add = add i32 4, %16 In this case, i would like to get the add instruction.

Hi, Is it possible to get debug information after optimization? for example, source code line numbers of instructions in an ir that is optimized by O2?

Hi Everyone, Does anyone know to get function parameters? For example, I want to get e and f in the call to function foo in the following code: foo(inr a , int b){ .... } main() { int e,f; e=10; f=22; *foo(e,f);* } I use the following code: for (auto& A : (cast<CallInst>(BI))->arg_operands ()) errs() << A.dump(); but I get a and b instead. Thank you

Hi, Do address spaces in llvm corespond to different memory locations? For example, Shared and Global refer to RAM while Local refers to registers? I guess that this may be true in GPU programming. So, I would like to know about CPUs. Thanks. Best, Mohammad -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hi, Could anyone please help me understand why Clang reallocates the same memory address for different variables while their lifetime intersect? Here is an example code: #include <stdlib.h> #include <stdio.h> #include <memory.h> #include <alloca.h> /* Checking information */ static int solutions[] = { 1, 0, 0, 2, 10, /* 5 */

...fferent backends attach different meanings. So for example an OpenCL backend might interpret address space 1 as local memory, 2 as private memory etc (in fact for OpenCL, these mappings are defined in the Clang frontend, if I recall correctly) Cheers, James On Wed, 23 Mar 2016 at 09:31, Mohammad Norouzi via llvm-dev < llvm-dev at lists.llvm.org> wrote: > Hi, > > Do address spaces in llvm corespond to different memory locations?

Hi, Is it feasible to assign different DataLayout to different address space in the same LLVM IR module?
