This type represents the target’s integer types. A built-in integer may be of any bit width and does not specify signedness.

An alias for .i(n) where n is the width of .ptr.

A built-in 16-bit floating-point type (specifically, “binary16” in IEEE 754).

A built-in 32-bit floating-point type (specifically, “binary32” in IEEE 754).

A built-in 64-bit floating-point type (specifically, “binary64” in IEEE 754).

A built-in 128-bit floating-point type (specifically, “binary128” in IEEE 754).

A built-in opaque pointer.

The type of the built-in module.
