| // Select the map type that this binary is built using. This is for common |
| // lookup methods like Type.Key to know which type to use. |
| // |
| // Note that mapType *must not be used by any functions called in the |
| // compiler to build a target program* because the compiler must use the map |
| // type determined by run-time GOEXPERIMENT, not the build tags used to build |
| // the compiler. |
| // |
| // TODO(prattmic): This package is rather confusing because it has many |
| // functions that can't be used by the compiler (e.g., Type.Uncommon depends on |
| // the layout of type + uncommon objects in the binary. It would be incorrect |
| // for an ad-hoc local Type object). It may be best to move code that isn't |
| // usable by the compiler out of the package. |
