Platform support

Host support and target support are separate claims. DByte v12.0.0 ships a Windows x64 host bundle; Linux and macOS host distributions are not released in this version.

00 current host distribution§

Host	v12.0.0	What that means
Windows x64	SUPPORTED	Official `dbyte-v12.0.0-windows-x64.zip` bundle and documented install path.
Linux x86_64	NOT RELEASED	No official v12.0.0 Linux host binary or install procedure.
macOS	NOT RELEASED	No official v12.0.0 macOS host binary or install procedure.

DO NOT INFER HOST SUPPORT: the implementation language, an ELF writer, or a freestanding target does not turn Linux and macOS into supported compiler hosts.

10 current execution · target profiles§

Profile	v12.0.0	Boundary
hosted tree	DOCUMENTED	Runs through the hosted interpreter semantics.
bytecode VM	DOCUMENTED	Runs through the hosted VM path.
`i686-dbyte-none`	DOCUMENTED	Freestanding/kernel profile; privileged native operations are profile-gated.
`i686-dbyte-user`	DOCUMENTED	User profile; syscall surface is separated from kernel-only native operations.
`x86_64-dbyte-none`	DEFERRED	Proposed v12.3 target.
`x86_64-dbyte-windows`	DEFERRED	Proposed v12.3 userspace target.
`x86_64-dbyte-linux`	DEFERRED	Proposed v12.3 Linux userspace target.

There is no current official install recipe because no v12.0.0 host distribution exists for either platform. Do not publish a fake curl | sh path, rename a freestanding ELF target as Linux support, or claim a source build as a supported host without a tagged contract and repeatable verification.

Linux is tracked as a proposed modern native target under historical v12.3 Modern Native plan (superseded by v12.2). That page is design intent, not shipped capability.

40 host != target§

HOST
  where dbyte / dbytec execute

TARGET
  what machine / ABI the compiler emits for

WINDOWS x64 HOST
  != Win64 native target proof

ELF32 OUTPUT
  != Linux userspace support

FREESTANDING i686
  != Linux host support

The canonical semantics remain shared. Profile and target layers choose available capabilities and physical ABI details; they do not redefine language meaning.

50 proof required before a platform becomes supported§

release artifact identity
exact version output
host smoke test
compiler + VM parity
native object/image inspection
exact stdout + exit status
deterministic rebuild where claimed
ABI-specific positive tests
ABI-specific negative tests
platform I/O proof
published verifier entrypoint

CURRENT CONTRACT: DByte 12.0.0. Future x86_64/Linux/Windows rows stay future tense until a later tagged release promotes them.
