The closure function (invoked as closure->fun in ffi_closure_XXX_inner)
will only populate the actual number of bytes for the true return type,
which may be a character. This leaves garbage on the stack when the
assembly closure function (i.e. ffi_closure_XXX) reads the return value
off of the stack into r0 as a 4-byte value. ffi_closure_XXX always
leaves room for at least 4 bytes here, so we can safely set them to 0.
Otherwise, if there is garbage in any of these bytes, these end up in r0
and in the returned value as well.
In eaa59755fc, macros from `unix64.S` were extracted into `asmnames.h` to be used with `win64.S` as well. As such these are required by `unix64.S`, which fails to build without them.
When running `make dist`, `configure.host` would not result in the distribution tarball, however `configure` would try to read it, and as such the tarball would not be buildable.
- Add missing files for desktop platforms in generate-darwin-source-and-headers.py, and in the Xcode project.
- Add a static library target for macOS.
- Fix "implicit conversion loses integer precision" warnings for iOS mad macOS targets.
Autoconf hasn’t had an update since 2014, and it doesn’t look like it will soon[1]
This updates config.{guess,sub}
It adds support for e.g. `-ios`, which allows to have targets like `aarch64-apple-ios`.
It basically does exactly what the config.guess script says:
> It is advised that you download the most up to date version of the config scripts from
The configure.ac script has been updated to relax `*-apple-darwin*` to `*-apple-*`.
Similarly the `.gitignore` and `autogen.sh` needed to be updated to respect the
newer `config.{sub,guess}`

By using VM_FLAGS_OVERWRITE there is no need for speculatively
allocating on a page we just deallocated. This approach eliminates the
race-condition and gets rid of the retry logic.
