# The Matrix
#
#####

# The matrix is the product of the following columns:
#
# |------------|----------|--------------|-------|
# | Compiler   ⨯ Platform ⨯ Architecture ⨯ libc  |
# |------------|----------|--------------|-------|
# | Cranelift  | Linux    | amd64        | glibc |
# | LLVM       | Darwin   | aarch64      | musl  |
# | Singlepass | Windows  | riscv        |       |
# |------------|----------|--------------|-------|
#
# Here is what works and what doesn't:
#
# * Cranelift works everywhere except */`loongarch64`,
#
# * LLVM works on Linux+Darwin/`amd64`,
#   and linux+`aarch64`, linux+`riscv`, linux+`loongarch64`
#   but it doesn't work on Darwin/`aarch64` or Windows/`aarch64`.
#
# * Singlepass works on Linux+Darwin+Windows/`amd64`,
#   and Linux+Darwin/`aarch64`
#   it doesn't work on */`riscv` or */`loongarch64`.
#
# * Windows isn't tested on `aarch64`, that's why we consider it's not
#   working, but it might possibly be.
# * The Only target for `riscv` familly of processor is the RV64, with the `GC` extensions
