/**
* @fileoverview System Five jump slot generator.
*
* We need to pass a magic number to the SYSCALL instruction in %rax.
* That's only possible to do in C using asm() macro wrappers, like in
* Chromium's "System Call Support" library. This technique is simpler
* to implement, gains us object-level ABI compatibility, hookability,
* and the ability to support significantly more functions, without the
* risk of slowing down builds too much with complicated headers.

Introduce native support for MacOS ARM64 There's a new program named ape/ape-m1.c which will be used to build an embeddable binary that can load ape and elf executables. The support is mostly working so far, but still chasing down ABI issues.

Get Cosmopolitan into releasable state A new rollup tool now exists for flattening out the headers in a way that works better for our purposes than cpp. A lot of the API clutter has been removed. APIs that aren't a sure thing in terms of general recommendation are now marked internal. There's now a smoke test for the amalgamation archive and gigantic header file. So we can now guarantee you can use this project on the easiest difficulty setting without the gigantic repository. A website is being created, which is currently a work in progress: https://justine.storage.googleapis.com/cosmopolitan/index.html

Implement crash reporting for AARCH64 The ShowCrashReports() feature for aarch64 should work even better than the x86 crash reports. Thanks to the benefit of hindsight these reports should be rock solid reliable and beautiful to read. This change also improves the syscall polyfills for aarch64. Some of the sys_foo() functions have been removed, usually because they're legacy or downright footguns not worth building.

Fully support OpenBSD 7.3 This change (1) upgrades to OpenBSD's newer kernel ABIs, and (2) modifies APE to have a read-only data segment. Doing this required creating APE Loader v1.1, which is backwards and forwards compatible with the previous version. If you've run the following commands in the past to install your APE Loader systemwide, then you need to run them again. Ad-hoc installations shouldn't be impacted. It's also recommended that APE binaries be remade after upgrading, since they embed old versions of the APE Loader. ape/apeuninstall.sh ape/apeinstall.sh This change does more than just fix OpenBSD. The new loader is smarter and more reliable. We're now able create much tinier ELF and Mach-O data structures than we could before. Both APE Loader and execvpe() will now normalize ambiguous argv[0] resolution the same way as the UNIX shell. Badness with TLS linkage has been solved. Fixes #826

Make improvements This change progresses our AARCH64 support: - The AARCH64 build and tests are now passing - Add 128-bit floating-point support to printf() - Fix clone() so it initializes cosmo's x28 TLS register - Fix TLS memory layout issue with aarch64 _Alignas vars - Revamp microbenchmarking tools so they work on aarch64 - Make some subtle improvements to aarch64 crash reporting - Make kisdangerous() memory checks more accurate on aarch64 - Remove sys_open() since it's not available on Linux AARCH64 This change makes general improvements to Cosmo and Redbean: - Introduce GetHostIsa() function in Redbean - You can now feature check using pledge(0, 0) - You can now feature check using unveil("",0) - Refactor some more x86-specific asm comments - Refactor and write docs for some libm functions - Make the mmap() API behave more similar to Linux - Fix WIFSIGNALED() which wrongly returned true for zero - Rename some obscure cosmo keywords from noFOO to dontFOO
