RISC-V Updated +Created
The leading no-royalties options as of 2020.
China has been a major RISC-V potential user in the late 2010s, since the country is trying to increase its semiconductor industry independence, especially given economic sanctions imposed by the USA.
E.g. a result of this, the RISC-V Foundation moved its legal headquarters to Switzerland in 2019 to try and overcome some of the sanctions.

LLVM IR hello world Updated +Created
Example: llvm/hello.ll adapted from: llvm.org/docs/LangRef.html#module-structure but without double newline.
To execute it as mentioned at github.com/dfellis/llvm-hello-world we can either use their crazy assembly interpreter, tested on Ubuntu 22.10:
sudo apt install llvm-runtime
lli hello.ll
This seems to use puts from the C standard library.
Or we can Lower it to assembly of the local machine:
sudo apt install llvm
llc hello.ll
which produces:
hello.s
and then we can assemble link and run with gcc:
gcc -o hello.out hello.s -no-pie
./hello.out
or with clang:
clang -o hello.out hello.s -no-pie
./hello.out
hello.s uses the GNU GAS format, which clang is highly compatible with, so both should work in general.

CC BY-NC-SA unfortunately.
Upload is actually optional, and it appears that teachers do retain their copyright: ocw.mit.edu/ans7870/global/MIT_OpenCourseWare_FAQs.pdf Hmmm, so how have they convinced so many teachers to do it?
MIT Radiation Laboratory Updated +Created
Made huge advances in radar.
Notably, Isidor Isaac Rabi was a leading figure there, and later he was head at the Columbia University laboratory that carried out the crucial Lamb-Retherford experiment and the anomalous magnetic dipole moment of the electron published at The Magnetic Moment of the Electron by Kusch and Foley (1948) using related techniques.
k-transitive group Updated +Created
TODO why do we care about this?
Note that if a group is k-transitive, then it is also k-1-transitive.
