For compatibility with math/bits uint operations. When math/big was written originally, the Go compiler used 32bit int/uint values even on a 64bit machine. uintptr was the type that represented the machine register size. Now, the int/uint types are sized to the native machine register size, so they are the natural machine Word type. On most machines, the size of int/uint correspond to the size of uintptr. On platforms where uint and uintptr have different sizes, this change may lead to performance differences (e.g., amd64p32).

Files in this directory are data for Go's API checker ("go tool api", in src/cmd/api).
Each file is a list of API features, one per line.
go1.txt (and similarly named files) are frozen once a version has been
shipped. Each file adds new lines but does not remove any.
except.txt lists features that may disappear without breaking true
compatibility.
next.txt is the only file intended to be mutated. It's a list of
features that may be added to the next version. It only affects
warning output from the go api tool.
