similar to: [LLVMdev] unique id for a llvm Instruction

Instruction pointers (or Value pointers) are thus commonly used as keys in hash tables or similar. Instructions or Values are almost never copied, so that you won't find the same instruction at

what if another pointer points to the same instruction? Is this possible to happen? Eirini -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.llvm.org/pipermail/llvm-dev/attachments/20130829/ad6ba4bb/attachment.html>

Hello, i would like to ask, is there a way to get a unique id for each llvm instruction? Eirini -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.llvm.org/pipermail/llvm-dev/attachments/20130829/ca483d68/attachment.html>

Hi, i want to get the address in memory of an instruction pointer and use it as a key in my tables. i iterate over the instructions in LLVM IR like this: for (Module::iterator fi = Mod->begin(), fi_end = Mod->end(); fi != fi_end; ++fi) { for (inst_iterator I = inst_begin(fi), E = inst_end(fi); I != E; ++I) { Instruction *ii = dyn_cast<Instruction>(&*I);

I am wondering whether the values of the casts are guaranteed to be unique for every instruction.

Hello, i parse the llvm IR (llvm-3.3 version) and when i meet a constant, i want to get it's value. eg i32 5, i want to get the 5. I am interested in ConstantInt-ConstantFP-ConstantArray-ConstantStruct subclasses. Things are a bit easier with ConstantInt and ConstantFP constants but how could i get the value of a ConstantArray? The

I am writing an analysis pass on LLVM which requires to: [1] generate unique, positive ID corresponding to each instruction [2] the ID must survive across runs [3] given the ID, corresponding instruction has to be mapped back For [1], the general suggestion is to use the Value* instr_ptr associated to each instruction. The instr_ptr points to specific instruction in memory, hence

I would like to create some tables for my instructions in the IR. For example a table that has all the store instructions. I want all the arguments to a function or instruction or constant etc to be trivial. So to fix my previous example instead of having : call void @llvm.memcpy.i32(i8* %19, i8* getelementptr inbounds ([2 x [2 x [3 x i8]]]* @main.s, i32 0, i32 0, i32 0, i32 0), i32 12, i32

> Isn't Instruction* a pointer to the instruction in memory? If so, it'll change across runs Correct, but none of this is meant to be stored across runs, so the actual address doesn't matter. You recompute the map every time your IR is loaded. On Mon, May 8, 2017 at 7:34 PM, Dipanjan Das via llvm-dev < llvm-dev at lists.llvm.org> wrote: > > > On 8 May 2017 at

David, As you suggested, I try to compile the following test code: *include "llvm/IR/Instruction.h"#include "stdint.h"extern void callback(intptr_t);void foo(){ llvm::Instruction* i; intptr_t zzzz=static_cast<intptr_t>(i); callback(zzzz);}* but got this compilation error: * 'intptr_t' (aka 'long') is not allowed intptr_t

Hi, I wonder whether we can easily retrieve an LLVM instruction ID that uniquely identifies the instruction. In my case, I need to avoid using llvm::Instruction* directly. Given an 'inst' of type llvm::instruction*, is there some readily usable method as simple as "int id = inst->id( )"? Thanks. Zhoulai -------------- next part -------------- An HTML attachment was

Hello, i am new to LLVM and i want to create my own project with a cpp file which calls llvm functions and then run it. I download clang source, llvm source and compiler-rt source. I tried to configure and build llvm using this http://llvm.org/docs/GettingStarted.html#getting-started-with-llvm but it failed because .h files included on top of the Hello.cpp couldn't found. Can you tell me

Hi, I have been a matlab user and is learning R. I want to convert a large list of strings to a list of unique numeric ids to reduce storage space. For example, there is a string list (there are duplicates) ABCDDDD ACCDEDF ACCGEDF ACCGEGF ..... ACCDEDF ACCGEGF and I want to have a corresponding numeric id list 1 2 3 4 .... 2 4 In matlab, the 'unique' function can do this in

Hi everyone, I am trying to insert a row in sqlite table with my own unique id. I want to create unique id using sqlite internal function last_insert_rowid() which returns the next max rowid of the table which is always unique. I tested this using sqlite and it works fine but when i run the same query using RSQlite from r prompt, my query doesn't create new unique id. last_insert_rowid()

Reading the wiki page on the topic above, the following doesn't seem entirely clear to me: must all used IDs be unique, or do just the user/computer accounts and the groups, respectively, need unique IDs? Simply put, is it possible that a user has a uidNumber that is the same as the gidNumber of a group? Thanks, Viktor

Hi Allaisone, I took a slightly different approach but you might find this either as or more useful than your approach, or at least a start on the path to a solution you need. df1 <- data.frame(CustId=c(1,1,1,2,3,3,4,4,4),DietType=c("a","c","b","f","a","j","c","c","f"),
