ObsoleteLLVMVersions [FreeBSD WIKI]

This is an old revision of the document!

There are many versions of llvm in the ports tree.

It is painful for builders (especially the ones using qemu) to have so many versions.
Some only exist to satisfy dependencies.

This page discusses the list of ports that we should try to update to reduce the dependencies.

The usage column does not include ports that hardwire the version (except for the llvm35 entry). See HardcodedLLVMVersions for that list.

port	usage	status	comments
llmv35	lang/pure and dependents	obsolete	tracking bug for removal
llvm60	fallback via USES=xyz for GCC-based archs	obsolete	defined in Uses/compiler.mk
llvm70	USES=obj (mostly gnustep-derived ports)	obsolete	defined in Mk/Uses/objc.mk
llvm80	tree-wide default	supported	defined in Mk/bsd.default-versions.mk
llvm90		brand new	PR to test llvm90 as the new default in individual ports

Processing INDEX-12 20190805 (and deleting self-references) produces:

 13 /tmp/llvm3
  0 /tmp/llvm4
  0 /tmp/llvm5
 31 /tmp/llvm6
127 /tmp/llvm7
250 /tmp/llvm8
  0 /tmp/llvm9

For architectures that support llvm in base, the default version is determined by whatever is installed in base.

For other architectures, if a port sets USES=compiler, clang60 will be set if:

See Uses/compiler.mk for the code.
