similar to: How to submit a patch?

I owe you a gala dinner at your favorite restaurant. Really. A few questions: Why did you 'git pull --rebase' when the branch was up-to-date? Is this just a safety habit? I don't understand the pushing upstream. Since we use Phabricator, isn't that the job of the person who commits the patch? Does git keep all my branches up-to-date with the origin? Say I come in tomorrow and

Hi Praveen, Thanks for the tip, but Xcode seems to spend all the time running tablegen "custom shell scripts", one by one at a time, not linking. Linking is actually very fast, possibly less than a second. The “scripts” that take longer are “AArch64CommonTableGen" and “AMDGPUCommonTableGen”. As said this is on LLVM 9.0. However, on LLVM 7.0.1, the same process takes just 5-6

This is also the case with the Visual Studio generators. Custom commands in a single cmake file essentially get written out line by line into a single batch file that gets processed as a custom build step. In the VS case this means that it can, for example, run X86 and Aarch64 tablegen steps in parallel with each other but all of the individual X86 invocations get processed serially. I can well

Yes, I confirm.

yeah i m concerned about jit compilation time.. On Sun, Jun 30, 2019 at 12:57 PM Praveen Velliengiri < praveenvelliengiri at gmail.com> wrote: > Yes I think so..

Hey Joan, When looking for build support it is really useful to include a bunch of information about your build up front. Knowing that you are on macOS, and using the Xcode generator are really useful. On macOS, BUILD_SHARED_LIBS won’t really help much because the default linker (ld64) is pretty good. Using an IDE generator and setting LLVM_USE_OPTIMIZED_TABLEGEN will kill your release builds.

And yet the same C++ code using thread-local variables works fine (or seems to) when compiled with Orc v1. Does the change to the Orc API really make thread-local storage more difficult?

You can add symbols from Archieve via StaticLibrarySearchGenerator. But it is added recently though On Tue, 27 Aug 2019 at 21:02, Praveen Velliengiri < praveenvelliengiri at gmail.com> wrote: > Hi Geoff, > I tried it, but I can't able to reproduce it. > > Test Program: > #include <fstream> > int main() > { > std::ifstream stream1, stream2; >

Thanks Praveen. Is it suitable for LLVM 7.0.1 ? Apart from flexibility, do we see any compile time improvements as well with ORC?

If someone can manage it, it wouldn't be a bad thing - obviously open up more parallelism (I don't know how much of LLVM can be built before you hit everything that needs tblgen run - I guess libSupport and some other bits) On Mon, Jul 1, 2019 at 12:54 PM Zakharin, Vyacheslav P via llvm-dev < llvm-dev at lists.llvm.org> wrote: > [resending to the whole list] > > > >

Hi! I think that comments section will help people to organize the Q&A in the same webpage. But it also leads to spam as you said, However, I don't have any strong rationale for enabling them :) Thanks for your reply Chris!

Trying to put together a simple test JIT compiler, using ORC which as I understand it will be the supported API going forward, I noticed that in the first chapter of the updated Kaleidoscope tutorial, there is sample code that starts like this: ExecutionSession ES; RTDyldObjectLinkingLayer ObjectLayer; IRCompileLayer CompileLayer; DataLayout DL; MangleAndInterner Mangle; ThreadSafeContext Ctx;

Hi, Yeah, now I understand the problem here. Thanks. But I too have another doubt in "Bounds check bypass store" In this example in the Speculative load hardening : unsigned char local_buffer[4];unsigned char *untrusted_data_from_caller = ...;unsigned long untrusted_size_from_caller = ...;if (untrusted_size_from_caller < sizeof(local_buffer)) { // Speculative execution enters here

Much of this has been discussed (over many, many years) on https://bugs.llvm.org/show_bug.cgi?id=28222 Some of the issues that were identified included: 1 - Poor tablegen dependency handling leading to unexpected rebuilds. 2 - Debug STL iterator checks taking an insane amount of time (might be MSVC specific). 3 - Lack of parallelization of custom commands (XCode and VS builds) - VS at least

Hi Guys! I'm Praveen Velliengiri, studying third year Msc Data Science at PSG COLLEGE OF TECHNOLOGY. I would like to participate in GSoC 2018 under LLVM Organization. I went through the GSoC Project ideas page and the LLVM mailing list. I really liked the *FUNCTION ATTRIBUTE INFERENCE *project. I'm starting to make initial studies for the project. I'm new to LLVM i don't know

Hi Praveen, Please, can you elaborate on this?. What do do mean by “building as shared objects”.

For example, the illustrate part says "ES.getMainJITDylib().setGenerator" while the full code list says "ES.getMainJITDylib().addGenerator", I guess the API is changed, the tutorial part is up to date while the full code list leaves to the old version.

Hi, Thanks for your email, I understand that the execution stalls until the predicated state is computed, then we mask pointers with all_zeros_mask if there is a mis-prediction. But I understand that as soon as the condition value is available, the processor can check about it's assumptions and revert back. That is, If the branch prediction is correct during speculation, we mask with
