Hi Chris, Thanks for the suggestion i was trying to use the patch https://reviews.llvm.org/D30691 and ASTimporter concept for cross file analysis. Can u explain in details the approach u suggested ? What is `nm` on the object files ? Can u suggest some approach to start on this cross file analysis tool. Thanks, Siddharth On Tue, Sep 19, 2017 at 9:42 PM, Chris Bieneman <beanz at apple.com>

(Apologies for the re-send Siddharth, I failed to cc the list) There is no existing tool that I'm aware of which performs this analysis on the AST. It is possible to do on an AST. You would just need to write an AST Visitor that finds declarations, definitions, and uses of functions. Is there a reason you need to do this at the AST level? With C code this analysis can be trivially performed

Hi, Thanks for the info, If i only want to run performance test on benchmarks for LTO and Thin LTO enabled target, Can u suggest ways to do it ? I want to do it at my end.

When to JIT from AST and when to JIT from LLVM IR? What is the logic behind extreme laziness? In what situations can it be beneficial and in what it is not? Does it depends on target architecture?

Hi Chris, Thanks for answering, Can u clarify on this comment mentioned in https://github.com/Z3Prover/z3/issues/861 . cplusplus no exception support · Issue #861 · Z3Prover/z3 · GitHub - LLVM's *source code* does not use exceptions for performance reasons and so is compiled by default with -fno-exceptions. When using LLVM's libraries via it's C++ interface it is important

Thanks. I am just trying to find a relocation and linking design for Hexagon architecture, whether to follow the MIPS style of relocation or other architecture style of relocation. Thats my question . Thats why i was asking about the functions and their differences Please guide.

Hi Siddharth, alternativly you can try this <https://github.com/rizsotto/scan-build>, it's written in Python.

Thanks for the reply. I was just asking about in general whatever header files are there in Targets/ for different architectures are not including any function except this processRelocationRef() to be used in RuntimeDyldELF.cpp or RuntimeDyldCOFF.cpp or RuntimeDyldMachO.cpp and i think these files are the ones which are actually doing the relocation and linking work. So what purpose do these

+Aaron because i think he uses scan-build on Windows more or less successfully. I won't have time for setting up a Windows machine for myself in the nearest future. Could you tell us exactly what you're doing and what exactly does it print to console, more in the spirit of http://www.catb.org/~esr/faqs/smart-questions.html ? > scan-build: Not supported for windows.

Thanks for the detailed explanation. So is changing the analysis technique from path sensitive (symbolic execution) analysis to some other technique bring in the soundness property ?

Hopefully someone else on the dev list who has experience with LNT and the LLVM test-suite will chime in. I've never run it myself. Adding Mehdi since he ran it with LTO/ThinLTO. I found some documentation for the test-suite: https://llvm.org/docs/TestingGuide.html#test-suite-overview http://llvm.org/docs/lnt/quickstart.html http://llvm.org/docs/lnt/tests.html#llvm-cmake-test-suite But I

Thanks for reply, it was really helpful. Can u just be more specific and tell about processRelocationRef() and resolveRelocation() in Targets/RuntimeDyld(objectfile format)(arch).h and also in RuntimeDyldELF.cpp and how the same function is implemented in different ways in both the files ?

yeah so when LTO runs, in the linker, it uses the target to produce object code. In the sense of code generation for target arch.

I'm not completely sure what you are asking. Are you looking for performance benchmarks to use for LTO and ThinLTO testing? Or are you asking how to build/run with LTO and ThinLTO? Are you asking how to run LLVM's performance test-suite with LTO and ThinLTO? Teresa On Fri, May 11, 2018 at 5:21 AM Siddharth Shankar Swain < h2015096 at pilani.bits-pilani.ac.in> wrote: > Hi, >
