similar to: [LLVMdev] CFG using LLVM

Hello, I am learning to write passes in LLVM and currently using LLVM 2.6. I followed the steps mentioned to write the helloworld pass and when i run it using opt, I get a Seg Fault. Not able to figure out why this is happening. It would be great if someone can point out where I am going wrong. Thanks.

Hi, I wish to implement dead code elimination as a pass in llvm. This is not the same as unreachable block. For this, I plan to go ahead like this : In each function Identify the store and branch operations Identify the operands involved in these operations. Build the UD chain of these and check if there is any variable that is not used and mark its definition (the entire instruction)

I used successors to find the basic blocks that can be visited and those that cannot be reached. My pass just prints out those blocks which can be reached. The problem is that I want to include this in my compiler code rather than as a separate .cpp file which will perform the pass when I use 'opt'. I have seen that there is something called a PassManager class. Will this help me any way ?

Hi All, The other thing we have noticed after booting is, screen is completely blank. GUI is not visible on attached monitor. We tried switching between different terminals using (Ctl+Alt+F1-12). F2-6 are showing command line terminals but, others are returning blank screen only. It appears that, there is some problem with GUI/gnome. Is there any way to fix this? Please help. Regards Hersh On

Hi everyone, I'm currently trying to run a study on irreducibility of C programs, and I've implemented structural analysis (original paper by Sharir, algorithm in Muchnick's book) as an LLVM pass. When my implementation becomes a bit less buggy I'll certainly look into including it in the LLVM project. As a test for the algorithm I've been producing LLVM bitcode for C files

Hi, I have been using VNC on CentOS 7 server from last couple of months and it was running all fine till last night. Unfortunately, there was an abrupt power failure and system got restarted. Now, when I try to login with VNCviwer, it thrown an error message- "*Gnome - oh no! Something has gone wrong "* with a logout option. When I click on logout, I see black/dark gray screen with 3

Hi, I have recently installed centOS 7 and trying to start vnc server on it. Somehow, I am unable to make vncserver working. I have modified iptable rules and xstartup file but it did not help. Has anyone else faced this problem earlier? Any help would be appreciated. Regards Hersh

There were no live connections. The problem what we had was more related to OS requirement for some software. This drive was not in a bad shape.

Hi, I am running VMware player on CentOS 5.4 and its working fine. However it does not allow me to increase the RAM more than 3GB. ?It keeps throwing error stating- "Requested memory size is greater than allowed maximum of 3072 MB. Could not initiate memory hot plug."? I understand from few threads that 32bit OS has this kind of limitation but I am able to understand why I am seeing

Hi All We want to install packages like xfig and transfig on centos 5.5. We found rpms available but them but it seems there are lot of dependencies for these packages. So we would like to setup yum repo for this. Can anyone suggest trusted baseurl for yum repo? Regards Hersh -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hi, There was some problem with our system so I re-installed the server with CentOS 7. Now, when I am trying to run 'fdisk -l' command, it is returning a broken output. It throws this error- "fdisk: cannot open /dev/sdc: Input/output error". There are valid /dev/sdd and /dev/sde devices which are mounted and they are accessible but, somehow /dev/sdc is having a problem and

I was trying to run the simplify CFG Pass in LLVM , and delete an unreachable basic block ("continuation" below ) after running one of my own IR transforms , but I keep getting the error - While deleting: i8* %g Use still stuck around after Def is destroyed: store i8 0, i8* %g I am well aware of what that means, but isn't the whole purpose of the "simplifyCFGPass" to

Simplifycfg doesn't get run by default even with -O3, but 'opt -simplifycfg' can do it. I'm looking to add this functionality to an optimizer program that uses the llvm libraries. What's the best way to do this? I don't really mind whether it becomes available as a command line option as in opt, or I need to hardcode it as always on. To make it available as a command line

Hi, I am trying to run a software which requires a specific version of glib(GLIBC_2.7).

Hi, I am unable to build the letor module. I am generating the configure file using autoconf.

Okay, as far as I can see looking through the output of that, the empty block isn't created near the end, it exists at the start and never goes away.

I forgot to mention, I have followed steps mentioned in this link https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/7/html/System_Administrators_Guide/ch-TigerVNC.html for configuring vnc. I have also tried upgrading VNCserver but that didn't help either. Regards Hersh On 28 June 2016 at 15:39, Hersh <parikhh1 at gmail.com> wrote: > Hi, > > I have been
