Hi guys, I've been using blocks for a while and found that current behavior is error prone. So I am going to propose to you the better one. Motivation: 1) The __weak variables in blocks are very common pattern. So having any implicit default behavior makes thing worse. 2) Some stupid mistakes like: __weak typeof (self) theSelf = self; ...^ { theSelf.blabla = .. .... [self blabla];

Hello, I have the following problem: I need to allocate an array. I know it's size - it's constant (ConstExpr), but my problem is that I know it only during the runtime (i.e for every variable I'm trying to allocate an array equal to size of a variable). As I understand I can't do it, since it's possible to initialize ArrayType only if I know it's size in integer units.

Hello, I'm having troubles with writing a pass. In my pass I've have created a function that has two parameters - both of type i8*. Initially I wrote this function in C, that I translated it into IR, and then by using llc -march=cpp I got it's implementation in cpp code that actually inserts IR instructions. Then, I inserted this cpp code in my pass. And in some places of a program

Can't you do it by performing some analysis on CFG? You can traverse that structure with BFS. And after that for all the BB you have visited more than once, you try to find a parent that has a branch instruction as a terminator. Additionally you ensure that there are no BB with branches as terminators on your way. If such parent exist, you mark that there is exist a direct connection between

Hello All, I want to dertermine whether a basicblock is in a conditional branch. such as, //============================= if a > 2 // BasicBlock A then BasicBlock B endif BasicBlock C //============================= What I want to identify is BasicBlock B, which is in a condtional block. but C is not. In other words, I want to distinguish BasicBlocks that * must * be executed and that
