Versions of LLVM

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.

Notes on versions

devel/llvm10 is actually version 10.0, and thus is sorted here after devel/llvm90, which is version 9.0. The same caveat will apply for devel/llvm11 and all subsequent versions.

Current versions in the tree

The usage column does not include ports that hardwire the version. See HardcodedLLVMVersions for that list.

Dependency statistics

Processing INDEX-13 20210124 (and deleting self-references) produces:

       6 /tmp/llvm60
      33 /tmp/llvm70
       9 /tmp/llvm80
     121 /tmp/llvm90
     170 /tmp/llvm10
       0 /tmp/llvm11

Default version

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, llvm10 will be set if:

• COMPILER_ARGS:Mc++17-lang
• COMPILER_ARGS:Mc++14-lang
• COMPILER_ARGS:Mc++11-lang
• COMPILER_ARGS:Mc++0x
• COMPILER_ARGS:Mc11

See Mk/Uses/compiler.mk for the code.
