...riority right now so I can contribute something useful. I've got good C/C++ skills and a great interest in compilers, so I'm excited to learn more about LLVM. Let me know what thoughts you have and which parts of the project it would make the most sense for me to work on.

...tch Peter attached. Peter - do you want to add that to llvm-lto2 so that we have a way of dumping the existing YAML supported summary info to stdout, or would you rather have Charles take that one over and submit it (probably just needs a test case).

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

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 (

After having successfully created and run a few RoR test projects via RadRails in MyEclipse, I imported one from an Oracle tutorial (http:// www.oracle.com/technology/pub/articles/saternos-rails.html?_template=/ocom/print), showing how to deal with a legacy Oracle database. Unfortunately, after having configured database.yml, I get the following error message when I attempt to start either a Mongrel or a WEBrick server: -e:4:in `load'': no such file to load - script/server...

...). - ideally we should be able to pipe the output if llvm-dis to llvm-as in a lossless manner (if our layering requires to use another tool than llvm-as, so be it). -- Mehdi 2017-06-02 20:36 GMT-07:00 Mehdi AMINI <joker.eph at gmail.com>: > > > 2017-06-02 8:46 GMT-07:00 Charles Saternos via llvm-dev < > llvm-dev at lists.llvm.org>: > >> Hey all, >> >> Below is the proposed format for the dump of the ThinLTO module summary >> in the llvm-dis utility: >> > > Our format are usually both way: you have to be able to parse them back. >...

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

..., the only way to view these records is via “llvm-bcanalyzer -dump”, then manually decoding the raw bitcode dumps.Relatedly, there is YAML reader/writer support for CFI related summary fields (-wholeprogramdevirt-read-summary and -wholeprogramdevirt-write-summary). Last summer, GSOC student Charles Saternos implemented support to dump the summary in YAML from llvm-lto2 (D34080), including the rest of the summary fields (D34063), however, there was pushback on the related RFC for dumping via YAML or another format rather than emitting as LLVM assembly.Goals: 1. Define LLVM assembly format for summary i...
