I decided to investigate a bit about the game tech and I was surprised to see it was developed with a custom engine by a relatively small studio. I know there are some companies using custom engines but it's very difficult to find a detailed market study with that kind of information curated and updated. So this article.

// nopTrunc propagates From values of truncation instructions that have no
// effect on type (where From and To type are the same).

// Example:
//
// before:
//    %10 = xor i32 %src2, %src1
//    %11 = trunc i32 %10 to i32
//    %12 = xor i32 %sum, %11
