Alternative to JuliaLang#58146. We want to compile a subset of the possible specializations of a function. To this end, we have a number of manually written `precompile` statements. Creating this list is, unfortunately, error-prone, and the list is also liable to going stale. Thus we'd like to validate each `precompile` statement in the list. The simple answer is, of course, to actually run the `precompile`s, and we naturally do so, but this takes time. We would like a relatively quick way to check the validity of a `precompile` statement. This is a dev-loop optimization, to allow us to check "is-precompilable" in unit tests. We can't use `hasmethod` as it has both false positives (too loose): ```julia julia> hasmethod(sum, (AbstractVector,)) true julia> precompile(sum, (AbstractVector,)) false julia> Base.isprecompilable(sum, (AbstractVector,)) # <- this PR false ``` and also false negatives (too strict): ```julia julia> bar(@nospecialize(x::AbstractVector{Int})) = 42 bar (generic function with 1 method) julia> hasmethod(bar, (AbstractVector,)) false julia> precompile(bar, (AbstractVector,)) true julia> Base.isprecompilable(bar, (AbstractVector,)) # <- this PR true ``` We can't use `hasmethod && isconcretetype` as it has false negatives (too strict): ```julia julia> has_concrete_method(f, argtypes) = all(isconcretetype, argtypes) && hasmethod(f, argtypes) has_concrete_method (generic function with 1 method) julia> has_concrete_method(bar, (AbstractVector,)) false julia> has_concrete_method(convert, (Type{Int}, Int32)) false julia> precompile(convert, (Type{Int}, Int32)) true julia> Base.isprecompilable(convert, (Type{Int}, Int32)) # <- this PR true ``` `Base.isprecompilable` is essentially `precompile` without the actual compilation.
