Cargo Features

[dependencies]
fat-macho = { version = "0.4.9", default-features = false, features = ["bitcode"] }
default = bitcode

The bitcode feature is set by default whenever fat-macho is added without default-features = false somewhere in the dependency tree.

bitcode default = llvm-bitcode

Features from optional dependencies

In crates that don't use the dep: syntax, optional dependencies automatically become Cargo features. These features may have been created by mistake, and this functionality may be removed in the future.
