Justine Tunney	f7ae50462a	Make improvements ... - Fix unused local variable errors - Remove yoinks from sigaction() header - Add nox87 and aarch64 to github actions - Fix cosmocc -fportcosmo in linking mode - It's now possible to build `make m=llvm o/llvm/libc`	2023-07-10 04:35:14 -07:00
Justine Tunney	97b7116953	Hunt down more bugs ... After going through the MODE=dbg and MODE=zero build modes, a bunch of little issues were identified, which have been addressed. Fixing those issues created even more troubles for the project, because it improved our ability to detect latent problems which are getting fixed so fast.	2023-07-03 18:43:29 -07:00
Justine Tunney	197aa0d465	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 09:01:44 -07:00
