Currently Trans.trans_call takes an argument indicating whether it's an
initializing call, but it always behaves as though it's initializing, even if
the argument is false. This is because there's a bit of a subtlety involved in
refcounted values: the same referent may be used as both dst of the call and as
an arg, and we want to avoid having it drop before being pinned as an arg,
because the dst was dropped.

The existing code may have been born in the CoW era and may no longer represent
a real hazard if rearranged to just pin args first then drop dst; will need a
few careful tests to be sure the arrangement actually works.

(Alternatively: worst case, make a static pass that prohibits x = f(x) the same
way f(x,x) is to be prohibited if both slots are alias-mode.)

Now actually dropping on non-init; added output-slot-variants.rs to test somewhat more thoroughly and of course several forms crash. More work to do here.

WONTFIX (not required for bootstrapping)

jannic added a commit to jannic/rust that referenced this issue May 30, 2017
Without that flag, LLVM generates unaligned memory access instructions, which are not allowed on ARMv5.

For example, the 'hello world' example from `cargo --new` failed with:
```
$ ./hello
Hello, world!
thread 'main' panicked at 'assertion failed: end <= len', src/libcollections/vec.rs:1113
note: Run with `RUST_BACKTRACE=1` for a backtrace.
```

I traced this error back to the following assembler code in `BufWriter::flush_buf`:
```
    6f44:       e28d0018        add     r0, sp, rust-lang#24
[...]
    6f54:       e280b005        add     fp, r0, rust-lang#5
[...]
    7018:       e5cd001c        strb    r0, [sp, rust-lang#28]
    701c:       e1a0082a        lsr     r0, sl, rust-lang#16
    7020:       03a01001        moveq   r1, rust-lang#1
    7024:       e5cb0002        strb    r0, [fp, rust-lang#2]
    7028:       e1cba0b0        strh    sl, [fp]
```

Note that `fp` points to `sp + 29`, so the three `str*`-instructions should fill up a 32bit - value at `sp + 28`, which is later used as the value `n` in `Ok(n) => written += n`. This doesn't work on ARMv5 as the `strh` can't write to the unaligned contents of `fp`, so the upper bits of `n` won't get cleared, leading to the assertion failure in Vec::drain.

With `+strict-align`, the code works as expected.

Change prefetch to avoid deadlock

Was abled to reproduce the deadlock in rust-lang#118205 and created a coredump when it happen. When looking at the backtraces  I noticed that the prefetch of exported_symbols (Thread 17 frame 4) started after the "actual" exported_symbols (Thread 2 frame 18) but it also is working on some of the collect_crate_mono_items (Thread 17 frame12 ) that Thread 2 is blocked on resulting in a deadlock.

This PR results in less parallell work that can be done at the same time but from what I can find we do not call the query exported_symbols from multiple places in the same join call any more.

Change prefetch to avoid deadlock

Was abled to reproduce the deadlock in rust-lang#118205 and created a coredump when it happen. When looking at the backtraces  I noticed that the prefetch of exported_symbols (Thread 17 frame 4) started after the "actual" exported_symbols (Thread 2 frame 18) but it also is working on some of the collect_crate_mono_items (Thread 17 frame12 ) that Thread 2 is blocked on resulting in a deadlock.

This PR results in less parallell work that can be done at the same time but from what I can find we do not call the query exported_symbols from multiple places in the same join call any more.

Change prefetch to avoid deadlock

Was abled to reproduce the deadlock in rust-lang#118205 and created a coredump when it happen. When looking at the backtraces  I noticed that the prefetch of exported_symbols (Thread 17 frame 4) started after the "actual" exported_symbols (Thread 2 frame 18) but it also is working on some of the collect_crate_mono_items (Thread 17 frame12 ) that Thread 2 is blocked on resulting in a deadlock.

This PR results in less parallell work that can be done at the same time but from what I can find we do not call the query exported_symbols from multiple places in the same join call any more.

Change prefetch to avoid deadlock

Was abled to reproduce the deadlock in rust-lang#118205 and created a coredump when it happen. When looking at the backtraces  I noticed that the prefetch of exported_symbols (Thread 17 frame 4) started after the "actual" exported_symbols (Thread 2 frame 18) but it also is working on some of the collect_crate_mono_items (Thread 17 frame12 ) that Thread 2 is blocked on resulting in a deadlock.

This PR results in less parallell work that can be done at the same time but from what I can find we do not call the query exported_symbols from multiple places in the same join call any more.
