Get setcontext() and getcontext() working on Aarch64 This change also adds the missing code for getting and restoring the thread's signal mask, since that's explicitly listed by the man page 2023-07-02 05:42:58 +00:00			`#ifdef __x86_64__`
Implement swapcontext() and makecontext() This change introduces support for Linux-style uc_context manipulation that's fast and works well on all supported OSes and architectures. It also integrates with the Cosmpolitan runtime which can show backtraces comprised of multiple stacks and fibers. See the test and example code for further details. This will be used by Mold once it's been vendored 2023-07-02 10:50:29 +00:00			`#define PC rip`
