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 04:23:25 -07:00			`#ifndef COSMOPOLITAN_TOOL_BUILD_LIB_LOADER_H_`

Make improvements - Emulator can now test the αcτµαlly pδrταblε εxεcµταblε bootloader - Whipped up a webserver named redbean. It services 150k requests per second on a single core. Bundling assets inside zip enables extremely fast serving for two reasons. The first is that zip central directory lookups go faster than stat() system calls. The second is that both zip and gzip content-encoding use DEFLATE, therefore, compressed responses can be served via the sendfile() system call which does an in-kernel copy directly from the zip executable structure. Also note that red bean zip executables can be deployed easily to all platforms, since these native executables work on Linux, Mac, BSD, and Windows. - Address sanitizer now works very well 2020-09-06 21:39:00 -07:00			`char *map;`
