This PR adds the Cosmopolitan Libc platform enabling compatibility with multiple x86_64 operating systems with the same binary. The platform is similar to the Linux platform, but for now only x86_64 with interpreter modes are supported. The only major change to the core is `posix.c/convert_errno()` was rewritten to use a switch statement. With Cosmopolitan errno values depend on the currently running operating system, and so they are non-constant and cannot be used in array designators. However, the `cosmocc` compiler allows non-constant case labels in switch statements, enabling the new version. And updated wamr-test-suites script to add `-j <platform>` option. The spec tests can be ran via `CC=cosmocc ./test_wamr.sh -j cosmopolitan -t classic-interp` or `CC=cosmocc ./test_wamr.sh -j cosmopolitan -t fast-interp`. |
