...As part of my research I am trying to implement the ARM NEON Intrinsics in the PowerPC LLVM backend. I am still at the beginning of my efforts and am not yet familiar with either the ARM or the PowerPC backends. After I started investigating the code and found out that in total it is more than 100 kloc for the two backends I thought it is a good idea to ask you for some hints of where I should start from. I have written a small unrelated experimental backend for LLVM before, so I have some experience with the topic. Thanks, - Stan -------------- next part -------------- An HTML attachment was...

It's not that clear how libcxxabi could be used in llvm tools, as IIUC this library is built independently. The demangler implementation there is 10 KLOC which are rather far from LLVM style. -- Alexey Samsonov, MSK -------------- next part -------------- An HTML attachment was scrubbed...

...ue to memory-unsafe issues. The report acknowledges difficulties in getting the numbers right, and of course makes no judgement as to the quality of any code. The report also acknowledges that there are good reasons for some usage of memory-unsafe code. openssh-portable is listed as having 142 KLoC of which 120 KLoC are written in memory-unsafe languages, for a ratio of 85%., Please recognize this is a statistic, not a judgement.

...crap, but here goes. maybe there was a FAQ for all this, but I missed it. well, I am not trying to demean LLVM in any way here, only trying to understand and evaluate things from my POV is all... sorry if at all I seem arrogant or condescending... well, running a linecounter, it is about 223 kloc (c++ ...), + 72 kloc headers. this is decently large. my compiler, in comparrision, is only about 62 kloc thus far, but I have about 300 kloc of 3D code in my main project, so ok, it balances I guess... ok, I also currently only do x86 (at present this is all I really need for my uses...)....

...? There was a Stensgaard algorithm implemented before, but noone was maintaning it, so it was removed. Do you think that this could be a suitable algorithm or should we choose something newer and stronger? Regarding the scalability, it ok for us, if the algorithm would run e.g. 1 hour for a 100 KLOC application. Thank you Adam Husar

I''m new to ROR, and am working my way through the Agile Web Development Book. In the test application, the authors tell me to test my database connection by performing "rake db:migrate". When I do, I get the error "Don''t know how to build task ''db:migrate''" I''ve been looking around at the files, and I see a reference to a

I probably shouldn't even comment, as I know so little about LLVM. But I've hand-written a couple kLOC of IR now and am starting to get a feel for the syntax, so I'll just say what "feels" right based on that and leave it to others to decide if I've absorbed enough to make any kind of sense. Just imagining myself using such a language extension, I really would not want an orde...

...? To give you an idea of what this involves, the current minidump parser in lldb is about 2000 LOC. It's already fairly independent of the rest of lldb, though it would need to be cleaned up a bit to be up to llvm standards. My expectation is that the yaml conversion code would add another 1-2 kLOC. The natural place for this in llvm would seem to be the Object library, so I'd propose for this code to be placed there. The thing I'm not sure about is whether it makes sense to integrate this into the existing ObjectFile hierarchy. While the minidump "streams" could be represe...

Even FreeBSD, which has removed it from the base system, tends to install the Perl package by default. In contrast, a lot of the machines I use don't have Python installed. I need to install it if I'm doing LLVM development because it's

Hi, I found that after moving to Clang pre-3.6 (git 65d8b4c4998b3a0c20934ea72ede72ef4838a004) and trunk (git 718825a8666acd9ceaab70fc7868332f20e2758f) our internal build machines started going offline in Jenkins. Clang after 3.5 release is consuming extreme amounts of memory in some cases. I have uploaded [1] one of affected files. $ g++ -std=c++11 -c -O1 -fPIC vpp_generated.ii -o
