unix/fs: a bit of cleanup around host-specific code
the actual target-specific things we want to test are all in getrandom, and rand already tests miri itself
also add some comments for why we keep certain old obscure APIs supported
reduce test_dependencies Also add comments for why we need all these 3 random functions for Windows, and the old Linux syscall interface.
Solaris: make pre-main code work Fixes rust-lang/miri#3566
avoid code duplication between realloc and malloc
Implement wcslen
organize libc tests into a proper folder, and run some of them on Windows
README: update introduction For some time now, we have (to my knowledge) been able to detect all the UB that rustc actually exploits. I think it's time to advertise that. We also haven't had the problem of "not every nightly has Miri" for a while. `@rust-lang/miri` what do you think?
…an give better errors
io::Error handling: keep around the full io::Error for longer so we can give better errors This should help with the error message in rust-lang/miri#3587.
…RalfJung Implement non-null pointer for malloc(0) Use non-null pointer for malloc(0) as mentioned in rust-lang#3576 to detect leaks and double free of ``malloc(0)`` addresses.
Allow test targets to be set via CLI args Fixes rust-lang#3584 I'm not a pro shell script reader as I am a Windows user, but we shall see if the CI script broke.
make MIRI_TEST_TARGET and RUSTC_BLESS entirely an internal thing They are just used to communicate between `./miri test`/`./x.py test miri` and the test harness, but should not be used by users.
do not run symlink tests on Windows hosts Fixes rust-lang/miri#3587
rename 'extern-so' to 'native-lib' Calling "extern" functions is not super clear IMO (extern to what), but saying that we are calling "native" functions from inside the interpreter makes it very clear I think.
Automatic Rustup
alloc: update comments around malloc() alignment Also separate the C heap shims form the Windows heap shims; their guarantees aren't quite the same.
