I skimmed over the source code in the afternoon, and indeed the encodings are textbook example of what should be auto-generated. However I didn't find the DSL syntax to be particularly palatable... maybe I was just reading a bit too quickly though. > Do you know developers / companies who might be interested in working > on this? As Song replied, Loongson Corporation should be very interested in testing their own offerings. This collaboration is exactly what we as a community strive for, and I'll happily review any code here or in loongarch-opcodes repo for that. > > Regards, > > Phil. > > [1] genqemutcgdefs from > https://github.com/loongson-community/loongarch-opcodes > [2] https://lists.gnu.org/archive/html/qemu-devel/2021-09/msg06601.html > [3] https://git.linaro.org/people/pmaydell/risu.git/tree/README > [4] https://lists.gnu.org/archive/html/qemu-devel/2021-09/msg04558.html
