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.
It's now possible to run commands like:
make -j8 m=aarch64 o/aarch64/test/libc/str
Which will cross-compile and run the test suites in a qemu-aarch64
binary that's vendored in the third_party/qemu/ folder within your
x86_64 build environment.
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.
