These little VMs in applications are everywhere. Apple Mach-O binaries have built in opcodes for binding and rebasing symbols interpreted by (numerous) little VMs in dyld: https://github.com/apple-oss-distributions/dyld/blob/e9da5ae571b4191dcdbcfd827363f19847c84561/common/MachOAnalyzer.cpp#L1439-L1698 https://github.com/apple-oss-distributions/dyld/blob/e9da5ae... https://github.com/apple-oss-distributions/dyld/blob/e9da5ae571b4191dcdbcfd827363f19847c84561/common/MachOAnalyzer.cpp#L934-L1022 https://github.com/apple-oss-distributions/dyld/blob/e9da5ae... Their use is less common now since the introduction of the mach-o load command LC_DYLD_CHAINED_FIXUPS, but these opcodes still have to be supported for older binaries. Also, some popular compilers including Zig still emit these opcodes for LC_DYLD_INFO and LC_DYLD_INFO_ONLY.
