d473242ecd Auto merge of #1617 - JCTyblaidd:data_race_detector, r=RalfJung 
Add simple data-race detector

Partially fixes data-race detection, see #1372, based on Dynamic Race Detection for C++11

- This does not explore weak memory behaviour, only exploring one sequentially consistent ordering.
- Data-race detection is only enabled after the first thread is created, so should have minimal overhead for non-concurrent execution.
- ~~Does not attempt to re-use thread id's so creating and joining threads lots of time in an execution will result in the vector clocks growing in size and slowing down program execution~~ It does now

Add an fn_ptr field to MiriFrame 
The `backtrace-rs` crate can use this to implement
`Frame::symbol_address`, which is used to skip frames
above the call to `Backtrace::capture` on the stack.

The function pointer will not be useable for comparison purposes if the
function is generic, as CTFE creates a new function pointer for each
cast of a (monomorphized) generic function. However, this already
affects code running under Miri, and isn't a problem for `backtrace-rs`
(which only casts a non-generic function).

I've added logic to allow `MiriFrame` to have either 4 or 5 fields - if
a 5th field is present, we write the function pointer to it.

Add API for capturing backtrace 
This PR adds two new Miri-defined extern functions:
`miri_get_backtrace` and `miri_resolve_frame`, which are documented in
the README. Together, they allow obtaining a backtrace for the currently
executing program.

I've added a test showing how these APIs are used. I've also prepared a
companion PR `backtrace-rs`, which will allow
`backtrace::Backtrace::new()` to work automatically under Miri.

Once these two PRs are merged, we will be able to print backtraces from
the normal Rust panic hook (since libstd is now using backtrace-rs).

A few notes:
* Resolving the backtrace frames is *very* slow - you can actually see
  each line being printed out one at a time. Some local testing showed
  that this is not (primrary) caused by resolving a `Span` - it seems
  to be just Miri being slow.
* For the first time, we now interact directly with a user-defined
  struct (instead of just executing the user-provided MIR that
  manipulates the struct). To allow for future changes, I've added
  a 'version' parameter (currently required to be 0). This should allow
  us to change the `MiriFrame` struct should the need ever arise.
* I used the approach suggested by @oli-obk - a returned backtrace
  pointer consists of a base function allocation, with the 'offset'
  used to encode the `Span.lo`. This allows losslessly reconstructing
  the location information in `miri_resolve_frame`.
* There are a few quirks on the `backtrace-rs` side:
  * `backtrace-rs` calls `getcwd()` by default to try to simplify
    the filename. This results in an isolation error by default,
    which could be annoying when printing a backtrace from libstd.
  * `backtrace-rs` tries to remove 'internal' frames (everything between
     the call to `Backtrace::new()` and the internal API call made by
     backtrace-rs) by comparing the returned frame pointer value to
     a Rust function pointer. This doesn't work due to the way we
     construct the frame pointers passed to the caller. We could
     attempt to support this kind of comparison, or just add a
    `#[cfg(miri)]` and ignore the frames ourselves.

563fb8e43d Implement dup and close for stdin/stdout/stderr 
Support F_DUPFD on stdin/stdout/stderr

Enable `close`-ing stdin/stdout/stderr

For `dup`, check if FD is `File` first

If not, clone the appropriate standard IO stream

Merge POSIX `close` and `dup` tests into same module

Also, add assertion that `write` on a closed FD returns an error.

Add `dup` as FileDescriptor trait fn

Also:
- Fix `close` so it drops `self` instead of reference to it
- Remove FD clamping in insert_fd_with_min_fd, since FDs 0-2 can be
closed

Fix fs_libc tests

Make error message when closing stdin/out/err more specific

Return io::Result from `FileDescriptor::dup`

Change error message when closing stdin/out/err

Refactor `FileDescriptor::dup` impl for `FileHandle`

Remove empty line

Nanosleep

This PR adds a shim for `libc::nanosleep`, (available under -Zmiri-disable-isolation only) which backs `thread::sleep` on Linux and macOS. I started off by extracting the `timespec` parsing from the `pthread_cond_timedwait` shim into a helper method, and adding checks for invalid values. The second commit adds the new shim and a small test. The shim blocks the current thread, and registers a timeout callback to unblock the thread again, using the same method as `pthread_cond_timedwait` does.

Move panic payload state from Machine to Thread

This PR moves the panic payload storage from the `Machine` state to per-thread state. Prior to this change, if one thread panicked while another was still unwinding, Miri would fail with `thread 'rustc' panicked at 'the panic runtime should avoid double-panics', src/shims/panic.rs:51:9`. I ran into this issue while prototyping a round-robin scheduler, but it's also reachable with the current scheduler and contrived programs that use blocking API calls to cause thread switching during unwinding. I wrote a test case along those lines for this change.

Print hex dump of alloc on reading undef bytes

Here's a small addition I made locally to the UB diagnostics, in case you're interested in it. This PR calls `dump_alloc()` on the relevant allocation if Miri fails on UB due to reading undefined bytes. This came in handy when diagnosing such an issue in a large program using unsafe Rust, in part because it wasn't deterministic enough to use `-Zmiri-track-alloc-id=`. If you'd like to put this behind another -Z flag, let me know.

Handle std::sync::atomic::spin_loop_hint()

This PR adds support for `std::sync::atomic::spin_loop_hint()` by implementing the `llvm.x86.sse2.pause` intrinsic when the target is x86-based. It appears this is the first LLVM intrinsic in foreign_items, so I added a couple match blocks to handle it or fall through to the different OS-specific methods. I added a basic smoke test to `tests/run-pass/sync.rs`. I came across this by way of `crossbeam::utils::Backoff::spin()`, FWIW.

@hanna-kruppe would be great if you could have a look at this.

`float.rs` tests legal casts. `test_cast` checks that both `as` casts and unchecked casts work (i.e., these are not saturating). The `compile-fail` tests should ensure that illegal casts via the intrinsic are detected as such.

Add support for creating `std::time::Instant` in Windows

Includes shims for `QueryPerformanceCounter` & `QueryPerformanceFrequency` in Windows, which are both called in Windows when `std::time::Instant` is created.

Windows docs page ["Acquiring high-resolution time stamps"](https://docs.microsoft.com/en-us/windows/win32/sysinfo/acquiring-high-resolution-time-stamps) was helpful in learning how `QueryPerformanceCounter` & `QueryPerformanceFrequency` work.

the stack trace is already printed, this just adds an optional message the caller can pass, and I just pass the same message we passed to the panic but now to the abort instead.

574d81ce79 Auto merge of #1208 - christianpoveda:environ-shim, r=RalfJung 
Environ shim

Remake of https://github.com/rust-lang/miri/pull/1147. There are three main problems with this:

1. For some reason `update_environ` is not updating `environ` when `setenv` or `unsetenv` are called. Even then it works during initialization.
2. I am not deallocating the old array with the variables in `update_environ`.
3. I had to store the `environ` place into `MemoryExtra` as a field to update it. I was thinking about changing `extern_statics` to store places instead of `AllocID`s to avoid this.

Add directory-related shims

This PR adds support for `mkdir`, `rmdir`, `opendir`, `closedir`, and `readdir64_r`.

Open directory streams are tracked through a HashMap indexed by pointer locations, which holds directory iterators. Since `DIR` is an opaque type in glibc, I represent them with 1-byte allocations, and then just use their pointers in HashMap lookups.

Tests are included to exercise the new functionality.

Add statx shim for linux target

This is an attempt to fix: https://github.com/rust-lang/miri/issues/999 (for linux only)

Currently there is one problem that I haven't been able to solve. `std::fs::metadata` fails because the creation time is not available even though it is provided in the shim code.

In order to inform the caller that the field was provided, the `stx_flag` field must have the bits of `STATX_BTIME` set (which they are). The creation time is in the `stx_btime` field of the `statx` struct (see [1]). The relevant code in `libstd` is here (probably?): https://github.com/rust-lang/rust/blob/master/src/libstd/sys/unix/fs.rs#L322

Another important point is that we are just providing the fields that are available in "all" platforms (this is, without using any platform specific traits or so). This can be improved later.

References:
[1] Man page: http://man7.org/linux/man-pages/man2/statx.2.html
[2] libc `statx` struct: https://docs.rs/libc/0.2.63/libc/struct.statx.html

Edit: The problem is that my filesystem is not providing it and I thought all filesystems could provide it. I changed the code so it only provides those dates if they are available. now we are ready to go.

Support unwinding after a panic 
Fixes #658

This commit adds support for unwinding after a panic. It requires a
companion rustc PR to be merged, in order for the necessary hooks to
work properly.

Currently implemented:
* Selecting between unwind/abort mode based on the rustc Session
* Properly popping off stack frames, unwinding back the caller
* Running 'unwind' blocks in Mir terminators

Not yet implemented:
* 'Abort' terminators

This PR was getting fairly large, so I decided to open it for review without
implementing 'Abort' terminator support. This could either be added on
to this PR, or merged separately.
