1 Code in the musl directory is based on musl revision
2 b07d45eb01e900f0176894fdedab62285f5cb8be, which is v1.1.23, from
3 git://git.musl-libc.org/musl.
5 Whole files which are unused are omitted. Changes to upstream code are wrapped
6 in preprocessor directives controlled by the macro `__wasilibc_unmodified_upstream`.
8 Some major known missing areas include:
16 - environment variables
19 - TIOCGWINSZ (because cloudabi lacks it; affects isatty, line buffering for stdout)
20 - O\_CLOEXEC, O\_NOCTTY (because cloudabi lacks them)
