These fields are technically mutable, but inference knows they are never actually mutated. However, they can change between processes since staticdata.c has special handling to relocate them. fixes #61590
The Compiler module
This directory maintains the implementation of the Julia compiler.
Through a bootstrapping process, it is bundled into the Julia runtime as Base.Compiler.
You can also use this Compiler module as the Compiler standard library by following the steps below.
How to use
To utilize this Compiler.jl standard library, you need to declare it as a dependency in
your Project.toml as follows:
Project.toml
[deps]
Compiler = "807dbc54-b67e-4c79-8afb-eafe4df6f2e1"
[compat]
Compiler = "0.1"
With the setup above, the special placeholder version (v0.1) will be installed by default.1
If needed, you can switch to a custom implementation of the Compiler module by running
pkg> dev /path/to/Compiler.jl # to use a local implementation
or
pkg> add https://url/of/Compiler/branch # to use a remote implementation
This feature is particularly useful for developing or experimenting with alternative compiler implementations.
Note
The Compiler.jl standard library is available starting from Julia v1.10. However, switching to a custom compiler implementation is supported only from Julia v1.12 onwards.
Warning
When using a custom, non-
Baseversion ofCompilerimplementation, it may be necessary to runInteractiveUtils.@activate Compilerto ensure proper functionality of certain reflection utilities.
