similar to: in an IR pass: access the instruction pointer/BB address

Hi Eli, I know the page, and the only mentioning about LTO or link time optimization I found is the option PassManagerBuilder::EP_FullLinkTimeOptimizationLast - and nobody knows how this works (and asked about it on this list too before with no reply), and the author who wrote that part in the llvm code at Redhat did not reply to a question how to actually use it. And there is no example code or

HI Eli, that sounds like the -mllvm option would be a good a mention in the WritingAnLLVMPass document ;-) Two further questions for this and I am keeping this on the list so other people have pointers to this if they struggle with the same thing: 1. Does this require to use lld? (I am sure it is, just to clarify, for the very low chance that it would also work with gnu ld and the llvm gold

Not sure that works.  I had that initially: auto cf = IRB.CreateICmpULT(Incr, ConstantInt::get(Int8Ty, 1)); auto carry = IRB.CreateZExt(cf, Int8Ty); Incr = IRB.CreateAdd(Incr, carry); it makes no difference to the generated assembly

Hello, I have an optimisation issue in an llvm IR pass - the issue being that unnecessary instructions are generated in the final assembly (with -O3). I want to create the following assembly snippet: mov dl,BYTE PTR [rsi+rdi*1] add dl,0x1 adc dl,0x0 mov BYTE PTR [rsi+rdi*1],dl however what is created is (variant #1): mov dl,BYTE PTR [rsi+rdx*1] add dl,0x1 cmp

Hello, I am developing an LTO instrumentation of programs for fuzzing (for afl++) and I run into the following problem: a lot of open source program have multiple definitons of the same functions. In normal compile mode this is not a problem, however with LTO this only works with the linker option: -Wl,--allow-multiple-definition Now to be able to instrument (it is an "opt"

Hi, I just spent 4 hours trying to find a way to get the name of the resolver function of a ifunc definition ... :-( and with all that time I didnt event get far: for (GlobalIFunc &IF : M.ifuncs()) { StringRef ifunc_name = IF.getName(); Constant *r = IF.getResolver(); But how do I get to the (Function*) or function name of the resolver from there? I tried everything with the Constant

I searched the doxygen documentation and could not find a solution to my task: In a ModulePass running at EP_OptimizerLast, if I have a function F like in: bool Foo:runOnModule(Module &M) { LLVMContext &C = M.getContext(); for (auto &F : M) { // magic here if I want to know from which function (callee) each function is called - how can I do this? (so that I e.g. have

Hi all, I have a question concerning block address class in LLVM. I am currently working on a project where I need to obtain and manipulate basic block virtual addresses. I was searching the web and found the llvm::BlockAddress class (http://llvm.org/doxygen/classllvm_1_1BlockAddress.html). With this class I was able to obtain a printout like this: i8* blockaddress(@func_name, %bb_label) How do

Hi all. I'm having problems trying to suspend/hibernate my Dell Latitude D810 Laptop. Basically I have an ATI X600 videographics and SATA harddrive and run httpd and mysqld daemons on it. I use fglrx (ATI propietary drivers) and the open too with no success. I tried with 1 and 2 screens configurations with no success. I tried with CA and/or with battery with no success. I need some help

Hello If you use Gluster as FUSE mount it's always slower than you expect it to be. If you want to get better performance out of your oVirt/Gluster storage, try the following: - create a Linux VM in your oVirt environment, assign 4/8/12 virtual disks (Virtual disks are located on your Gluster storage volume). - Boot/configure the VM, then use LVM to create VG/LV with 4 stripes (lvcreate -i

Since the getelementptrs were implicitly generated by the CreateStore/Load I'm not sure how to get access to them. So I hacked the assignment to be done thrice: once using a manual decomposition into two GEPs and stores, once using the "big" CreateStore, once via the setGlobal function, printing addresses and memory contents at each point to the degree that I have access to them.

Subject says it all- has anyone got any recommendations for rpm-packaged forum/bb software for CentOS 5 - preferrably from a repo like rpmforge or similar so it will get updates as they come through? Yes, I can install phpBB et al from scratch but I with 'yum update' it is harder for me to miss updates :-) -- Cheers, Tony

Hi everyone, I'm faily new to LLVM, I'm working on a new backend. In my backend, one of the requirements is to split a BB on every call, I considered putting some kind of pseudo instruction using the TargetLowering::LowerCall function. Before going said path, I was wondering if there is some way to split the BB before the SelectionDAG is generated, this way the call instruction would be

Dear LLVM, I want to know, given a function, How do I know which block is entry block, which blocks are exit blocks? Is there any efficient way to dicectly get that information?

Given a function you can always use Function::getEntryBlock() to get the entry block. You need to scan the function to get the returning nodes. -Chris "llvm" Lattner --
