Matt Godbolt (@mattgodbolt) joined us to talk about assembly code, becoming a verb, 6502s, exploring compilers, and application binary interfaces.

Compiler Explorer can be found at godbolt.org. The code is on github (compiler-explorer/compiler-explorer).

Matt also has jsbeeb, a BBC Micro (6502) simulator. You can try it out at bbc.godbolt.org. Its code and more information is on github (mattgodbolt/bbc-micro-emulation). Matt recently gave a video presentation about jsbeeb for ABUG.

The best compiler book seems to be The Dragon Book.
