#
# The Matrix
#
#####

# The matrix is the product of the following columns:
#
# |------------|-----------|----------|--------------|-------|
# | Compiler   ⨯ Engine    ⨯ Platform ⨯ Architecture ⨯ libc  |
# |------------|-----------|----------|--------------|-------|
# | Cranelift  | Universal | Linux    | amd64        | glibc |
# | LLVM       | Dylib     | Darwin   | aarch64      | musl  |
# | Singlepass | Staticlib | Windows  |              |       |
# |------------|-----------|----------|--------------|-------|
#
# Here is what works and what doesn't:
#
# * Cranelift with the Universal engine works everywhere,
#
# * Cranelift with the Dylib engine works on Linux+Darwin/`amd64`, but
#   it doesn't work on */`aarch64` or Windows/*.
#
# * LLVM with the Universal engine works on Linux+Darwin/`amd64`,
#   but it doesn't work on */`aarch64` or Windows/*.
#
# * LLVM with the Dylib engine works on
#   Linux+Darwin/`amd64`+`aarch64`, but it doesn't work on Windows/*.
#
# * Singlepass with the Universal engine works on Linux+Darwin/`amd64`, but
#   it doesn't work on */`aarch64` or Windows/*.
#
# * Singlepass with the Dylib engine doesn't work because it doesn't
#   know how to output object files for the moment.
#
# * Windows isn't tested on `aarch64`, that's why we consider it's not
#   working, but it might possibly be.
