The primary job of a compiler is to translate source code into a binary
form that can be run by a computer. Increasingly, though, developers want
more from their tools, compilers included. Since the compiler must
understand the code it is being asked to translate, it is in a good
position to provide information about how that code will execute — and
where things might go wrong. At the 2023 GNU Tools Cauldron,
David Malcolm talked about recent work to improve the diagnostic output
from the GCC compiler.
