Hi, I was interested in trying out LLVM BOLT and generated profile data using Linux perf using the following: perf record -e cycles:u -o perf.data <command> This is without the use of LBR so I understand the performance improvements may not be much but this was more for becoming familiar with BOLT's commands. I then run: perf2bolt -nl -p perf.data -o perf.fdata <binary> and I

Hi all, I’ve been working on a Java-esque object-oriented language Bolt that targets LLVM IR. I’m agonisingly close to getting a virtual table working, and was hoping one of you could point out the gap in my understanding. I’ve linked the C++ code snippets relevant to the vtable below. Example IR generated (partially displayed below):

We are going to be at the llvm-dev meeting the next two days. We will get back to you after that.

Greetings, We, at Google, recently evaluated Facebook’s BOLT, a Post Link Optimizer framework, on large google benchmarks and noticed that it improves key performance metrics of these benchmarks by 2% to 6%, which is pretty impressive as this is over and above a baseline binaryalready heavily optimized with ThinLTO + PGO. Furthermore, BOLT is also able to improve the performance of binaries

Hello, I wanted to consolidate all the discussions and our final thoughts on the concerns raised. I have attached a document consolidating it. BOLT’s performance gains inspired this work and we believe BOLT is a great piece of engineering. However, there are build environments where scalability is critical and memory limits per process are tight : * Debug Fission,

Is there large value from deferring the block ordering to link time? That is, does the block layout algorithm need to consider global layout issues when deciding which blocks to put together and which to relegate to the far-away part of the code? Or, could the propellor-optimized compile step instead split each function into only 2 pieces -- one containing an "optimally-ordered" set of

Some more information about the relaxation pass whose effectiveness and convergence guarantees were listed as a concern: TLDR; Our relaxation pass is similar to what LLVM’s MCAssembler does but with a caveat for efficiency. Our experimental results show it is efficient and convergence is guaranteed. Our relaxation pass is very similar to what MCAssembler does as it needs to solve the same

Hi, I was trying to connect to ESX server using libvirt's virsh console but I am getting the following error: *virsh# connect esx://172.16.73.14* *Enter username for 172.16.73.14 [root]: root* *Enter root's password for 172.16.73.14:* *error: Failed to connect to the hypervisor* *error: internal error curl_easy_perform() returned an error: Peer certificate cannot be authenticated with

Just curious but how long has ESX support been in libvirt? Also I noticed this error when accessing one of my windows vms: error: internal error Expecting VMX entry 'scsi0.virtualDev' to be 'buslogic' or 'lsilogic' but found 'lsisas1068' Not sure whether this is an enhancement, defect, or not supported at this time. Thanks. -Jon
