Hi Dean, I have tried with -instr-map-1 and -instr-map-2, it didn't work. Is there a way to find the function name from the identifier? -DTharun On Mon, Jan 7, 2019 at 2:29 PM Dean Michael Berris <dean.berris at gmail.com> wrote: > Hi Dangeti, > > That's interesting -- can you try providing both `-instr-map-1=` and > `-instr-map-2=` even though they're the same

Hi, The call graphs generated by "*llvm-xray graph*" has function names, while the "*llvm-xray graph-diff*" doesn't shows function names. This is the command I am using llvm-xray graph-diff xray-log.clang.1 xray-log.clang.2 -instr-map=../xray-build/bin/clang -o diff.dot Attached is the portion of the generated diff graph. Am I missing any flag? [image: graph_diff.jpg]

Questions on LLVM vectorization diagnostics
Hi Dangeti, Ramakrishna, Adam, and Gerolf, >Yes this is an area that needs further improvement. We have some immediate plans to make these more useful. See the recent llvm-dev threads [1], [2]. It takes a lot of dedicated effort to make vectorization report easier to understand by ordinary programmers (i.e., those who are not compiler writers). Having done that for ICC ourselves, we truly

Question on target-features
Hi, In "target-features" list in LLVM-IR, there are "+feature", "-feature". My question is, does "-feature" is equivalent to not specifying a feature at all? For example: *attributes #0 = { "target-cpu"="znver2" "target-features"="+avx -avx2" }* Wheather it is equalent to omitting the avx2 from list? *attributes #0

Signed Div SCEVs
Hi, I am working with SCEVs, I see the unsigned division of SCEVs, it is not immediately clear to me why the signed division of SCEV expressions is not supported by SE? I would appreciate if some could clarify or point me to some links. -- Regards, DTharun -------------- next part -------------- An HTML attachment was scrubbed... URL:

Questions on LLVM vectorization diagnostics
Hi, Gerolf. We've been a bit quiet for some time. After listening to feedback on the project internally and externally, we decided to take a more generally accepted community development model ---- building up through a collection of small incremental changes ---- than trying to make a big step forward. That change of course took a bit of time, but we are getting close to the first NFC patch

Doubt regarding getAnalysisUsage
Hi, I have a doubt regarding *getAnalysisUsage.* My assumption is that, as analysis passes will not change the IR, all the passes required by an analysis pass should be preserved. Say, I have an analysis pass which requires another analysis pass called *SomeAnalysis* and I have not added *AU.addPreserved<SomeAnalysis>() *to my pass. Would the pass manager still considers the *SomeAnlaysis

Questions on LLVM vectorization diagnostics
Dear LLVM Community, I am D Tharun Kumar, masters student at Indian Institute of Technology Hyderabad, working in a team to improve current vectorizer in LLVM. As an initial study, we are studying various benchmarks to analyze and compare vectorizing capabilities of LLVM, GCC and ICC. We found that vectorization remarks given by LLVM are vague and brief, comparatively GCC and ICC are giving

register spilling and printing live variables
Hello, I have studied register allocation in theoretical aspects and exploring the same in the implementation level. I need a minimal testcase for register spilling to analyze spilling procedure in llvm. I tried with a testcase taking 20 variables but all the 20 variables are getting stored in the stack using %rbp. Maybe my live variable analysis is wrong. Please help me with a minimal testcase

Proposal for a LLVM front-end for P4 language
Dear community, We, a team at IIT Hyderabad are developing an LLVM front end for a networking language called P4 (https://p4.org/). Our work aims to enable LLVM based optimizations for P4. As the P4 language was designed to target many different switch architectures, we feel that P4 can comfortably fit in the LLVM framework where adding targets is more structured. The existing open-source P4

Strange connectivity problem from linux.
Hi I have been facing a strange connectivity problem from CentOS and Fedora boxes. When I telnet to $ telnet adp.eease.com 443 it works fine some times and every 5-10 tries or so it says connection refused. And this does not happen from my windows box. Can anyone from this list try this on their linux installation and see if they get the same behaviour? Thanks Tharun

LPR to windows lpd question
Hi All, I am trying to print from a CentOS 5.3 server to a windows LPD service. After enabling the LPD service on Windows and creating a LPR port to a particular printer when I execute the following command on CentOS server I do not come out. lpr -H winprint:515 -P printer1 file.txt The above command does not exit. Do I need to configure anything on the server to be able to use lpr as a client ?
