Hi Johannes, > I'd also like to know what the intention here is. What is tested and how? we have a few uses for these benchmarks in the technical report: http://lac.dcc.ufmg.br/pubs/TechReports/LaC_TechReport012020.pdf, but since then, we came up with other applications. All these programs produce object files without external dependencies. We have been using them to train a

Dear LLVMers, we, at UFMG, have been building a large collection of compilable benchmarks. Today, we have one million C files, mined from open-source repositories, that compile into LLVM bytecodes (and from there to object files). To ensure compilation, we perform type inference on the C programs. Type inference lets us replace missing dependencies. The benchmarks are available at:

Hi Johannes, > All the use cases sound reasonable but why do we need these kind of "weird files" to do this? > > I mean, why would you train or measure something on single definition translation units and not on the original ones, potentially one function at a time? I think that's the fundamental question :) The short answer is that it is hard to compile the files from

Hi Florian, we though about using UIUC, like in LLVM. Do you guys know if that could be a problem, given that we are mining the functions from github? > Have you thought about integrating the benchmarks as external tests into LLVM’s test-suite? That would make it very easy to play around with. We did not think about it actually. But we would be happy to do it, if the community accepts

Greetings LLVMers, I would like to add the licensed part of AnghaBench (http://cuda.dcc.ufmg.br/angha/) as an External Test in the LLVM test-suite. We have 128,411 files with their original licenses. (http://www.dcc.ufmg.br/~fernando/coisas/c_files_with_licenses.tar.gz) Each file is a single function, that compiles as is---no dependencies are needed. For instance, the commands below work for each

Hi Folks, I've been playing around with SYSLINUX for a little bit; here's what I'm trying to do... My disk will have three partitions: [BOOT: (FAT16 w/ SYSLINUX)] [OS1] [OS2] OS1 and OS2 will both contain an XP Embedded system which is read-only and which will always boot from a hibernate file. What I'd like to be able to do if flip-flop between them at runtime (that is, run

Hi. I'm trying to analyse information from a large database using R. I have some problems with quotes during the generation of strings. Setting: I extract data from a lot of sampling location (chemical data on water quality) and for each location I have a date of sampling and a value. I want to put everything in a list such that for each sampling point (say OS1) I have two columns

I'm trying to proess date/time fields from files that were given to me to analyze. Any clues what I'm doing wrong with strptime? This seems to fail the same way under Linux or Windows. For ?strptime would it make sense to explain %OS3 somewhere besides the Examples? > # Why does %OS3 work here? > format(Sys.time(), "%H:%M:%S") [1] "16:45:19" >

Hi everyone, while trying to use 'segmented' (R i386 2.15.0 for Windows 32bit OS) to determine the breakpoint I got stuck with an error message and I can't find solution.

Hi, I cannot figure out how to change the index format when displaying POSIXct objects. Would like the xts index to display as %H:%M:%OS3 when doing viewing the xts object.

The branch predictor of the implementation is not as accurate as the one from the paper, but it is close enough. Unfortunately, the branch predictor is a very expensive pass, because it relies on

C++ and Java memory models impose restrictions for locks and unlocks, such as a thread that releases a lock must acquired the lock, or the number of locks must be larger than the number of unlocks in the same thread... for enabling some optimizations, for example, simplifying trylocks (http://www.hpl.hp.com/techreports/2008/HPL-2008-56.html), and moving some instructions inside lock acquires

Hi Jeff, There is an algorithm to build the dominator tree that is O(n2), where n is the number of nodes on the control flow graph. I believe exists another that is linear, but I don't which one of them is implemented in LLVM. The problem is that the branch predictor requires post dominance information. None of the LLVM basic passes require post dominance information (AFAIK), hence it is
