Revision e7734ea0889c940c7dc57ba4e4401c93747fb428 authored by Abel Soares Siqueira on 03 March 2024, 01:23:18 UTC, committed by GitHub on 03 March 2024, 01:23:18 UTC
Hello! We noticed that your `CITATION.cff` had a small issue and fixed it. In addition to the fix, this Pull Request automates validation of that file using the [cffconvert GitHub Action](https://github.com/marketplace/actions/cffconvert). That way, it's a little bit easier to be robust against future changes to the `CITATION.cff` file. BTW it's perfectly fine if you don't feel like accepting this Pull Request for whatever reason -- we just thought it might be helpful is all. We found your repository using a partially automated workflow; if you have any questions about that, feel free to create an issue over at https://github.com/cffbots/filtering/issues/ On behalf of the cffbots team, @abelsiqueira / @fdiblen / @jspaaks --------- Co-authored-by: Max Horn <max@quendi.de>

// As of LLVM 13, there are two runtime JIT linker implementations, the older
// RuntimeDyld (used via orc::RTDyldObjectLinkingLayer) and the newer JITLink
// (used via orc::ObjectLinkingLayer).
//
// JITLink is not only more flexible (which isn't of great importance for us, as
// we do only single-threaded in-process codegen), but crucially supports using
// the Small code model, where the linker needs to fix up relocations between
// object files that end up far apart in address space. RuntimeDyld can't do
// that and relies on the Large code model instead, which is broken on
// aarch64-darwin (macOS on ARM64), and not likely to ever be supported there
// (see https://bugs.llvm.org/show_bug.cgi?id=52029).
//
// However, JITLink is a relatively young library and lags behind in platform
// and feature support (e.g. Windows, JITEventListeners for various profilers,
// etc.). Thus, we currently only use JITLink where absolutely required, that is,
// for Mac/aarch64 and Linux/aarch64.
