Part 3 in a series about improving Clang's constant expression interpreter.

A popular technique modern compilers use to improve the runtime performance of compiled code is to perform computations at compile time instead of at runtime. However, constant expressions need to be evaluated at compile time for a variety of reasons. To help resolve this problem, I've been working on improving the Clang's constant interpreter.

Timm Baeder explains the upstream work he has been doing on a new constant expression interpreter for Clang.
