Truffle is a framework for implementing languages as simple interpreters. Together with the Graal compiler, Truffle interpreters are automatically just-in-time compiled and programs running on top of them can reach performance of normal Java.

The Truffle framework provides the basic foundation for building abstract-syntax-tree (AST) interpreters that perform self-optimizations at runtime. The included TruffleDSL provides a convenient way to express such optimizations.

Truffle is developed and maintained by Oracle Labs and the Institute for System Software of the Johannes Kepler University Linz.

I didn't actually need any of this to install ade4 after uninstalling R 3.4.1 from MacPorts and using the official installer from https://cran.rstudio.com/bin/macosx/, which seems to have all the right pieces in place.

I was trying to install the motifStack Bioconductor package when I got this error.

ld: library not found for -lgfortran
clang: error: linker command failed with exit code 1 (use -v to see invocation)

Installing gfortran-4.2.3.pkg from CRAN's "R for Mac OS X" page helped, but I got the same error for libquadmath right afterwards, so it's not a total solution, and something else must be wrong.

alt toolchain that uses musl and has prebuilt toolchains/cross-compilers for various architectures

more fun than building llvm with musl by yourself..

Weld is a runtime for improving the performance of data-intensive applications. It optimizes across libraries and functions by expressing the core computations in libraries using a small common intermediate representation, similar to CUDA and OpenCL.
