Justine Tunney	417797d218	Support dirfd relative iops on Windows ... We always favor calling functions like openat(), fstatat(), etc. because Linux, XNU, FreeBSD, and OpenBSD all elected to support them, while some systems like Android love them so much, that they stopped supporting the old interfaces. This change ensures that when dirfd is actually a dirfd and not AT_FDCWD we'll do the right thing on Windows NT. We use an API that's been around since Vista to accomplish that. This change also adds exponential backoff to chdir() on Windows since it seems almost as flaky on Windows 7 as the rmdir() function.	2021-01-30 01:49:43 -08:00

Justine Tunney	f4f4caab0e	Add x86_64-linux-gnu emulator ... I wanted a tiny scriptable meltdown proof way to run userspace programs and visualize how program execution impacts memory. It helps to explain how things like Actually Portable Executable works. It can show you how the GCC generated code is going about manipulating matrices and more. I didn't feel fully comfortable with Qemu and Bochs because I'm not smart enough to understand them. I wanted something like gVisor but with much stronger levels of assurances. I wanted a single binary that'll run, on all major operating systems with an embedded GPL barrier ZIP filesystem that is tiny enough to transpile to JavaScript and run in browsers too. https://justine.storage.googleapis.com/emulator625.mp4	2020-08-25 04:43:42 -07:00
