similar to: GSOC ThinLTO Proposal

Oh I just see that there were already a bunch of answers. I missed the thread, sorry. So basically my intuitive approach on this is close to what I perceive Peter's position is: - don't create a new format if there is already one. - if you really have a good reason to create a new format, it should replace the existing one (i.e. don't maintain two). - ideally we should be able to

Hey all, Below is the proposed format for the dump of the ThinLTO module summary in the llvm-dis utility: > ../build/bin/llvm-dis t.o && cat t.o.ll ; ModuleID = '2.o' source_filename = "2.ll" target datalayout = "e-m:e-i64:64-f80:128-n8:16:32:64-S128" target triple = "x86_64-unknown-linux-gnu" @X = constant i32 42, section "foo", align

Hello, I'm Ruijie Fang, currently a 1st-year undergraduate at Princeton University, majoring in Computer Science. I am writing to to express my interest in the Google Summer of Code project: Improve MergeFunctions to incorporate MergeSimilarFunction patches and ThinLTO Support. I've read the LCTES'14 paper and found it quite interesting and comprehensible. I've also went as far

Great! For the hotness, try creating a small test case with a very hot loop that iterates many times. Let me know if you are still having trouble. While the llvm-dis serialization is being discussed, I suppose at the very least this can go in with the rest of the existing YAML summary dumping and get emitted from llvm-lto2 using the patch Peter attached. Peter - do you want to add that to

Hey all, I'm working on adding function attribute propagation to function summaries in the ThinLTO index, and have run into some trouble with ensuring bottom-up traversal when finding the SCCs in the call graph. I'm basing my implementation for the GraphTraits for the ModuleSummaryIndex off the GraphTraits<CallGraph *> implementation (

Dear All, On Wednesday, October 23 at 5 pm we will have a roundtable about LLVM's participation in GSoC and similar programs: http://llvm.org/devmtg/2019-10/#round The list of topics includes: - Overall organization of the project (timeline, ideas, etc) - Ideas lists - Lessons learned from past projects More topics for discussion are welcome! -- With best regards, Anton Korobeynikov

Hi, I'm interested in GSOC in general, but I missed this roundtable unfortunately. Any summary from this session?

Hey all, I'm working on adding interprocedural FunctionAttrs optimization ( http://llvm-cs.pcc.me.uk/lib/Transforms/IPO/FunctionAttrs.cpp) to ThinLTO so it does something similar to what LTO is doing ( https://bugs.llvm.org/show_bug.cgi?id=33648). I've hit a problem with how the FunctionAttrs optimization expects linkage types. In ThinLTO since the linkage type is set to External or

Hi Vishal, Ruijie, Thanks for your interest in the project. To get started, the first task would be to merge the 5 patches on top of trunk llvm. The list of patches are listed in the project description: http://llvm.org/OpenProjects.html#llvm_mergesim Please create an account in llvm phabricator (reviews.llvm.org) if you haven't already, and put your patches there. Let me know if you have
