Mint APE Loader v1.5 
This change ports APE Loader to Linux AARCH64, so that Raspberry Pi
users can run programs like redbean, without the executable needing
to modify itself. Progress has also slipped into this change on the
issue of making progress better conforming to user expectations and
industry standards regarding which symbols we're allowed to declare

*NSYNC

*NSYNC is a library providing scalable synchronization primitives. The following packages are provided:

  • THIRD_PARTY_NSYNC has nsync_mu which doesn't depend on malloc().
  • THIRD_PARTY_NSYNC_MEM has the rest of *NSYNC, e.g. nsync_cv.

The origin of this code is here:

git@github.com:google/nsync

NSYNC uses the Apache 2.0 license. We made the following local changes:

  • Write custom nsync_malloc_() so malloc() can use *NSYNC.

  • Rewrite futex() wrapper to support old Linux kernels and OpenBSD.

  • Normalize sources to Cosmopolitan style conventions; *NSYNC upstream supports dozens of compilers and operating systems, at compile-time. Since Cosmo solves portability at runtime instead, most of the build config toil has been removed, in order to help the NSYNC source code be more readable and hackable.
