The collector was asserting a total absence of projections, but some projections are expected, even in trans: in particular, projections containing higher-ranked regions, which we don't currently normalize.

2016-09-19Remove data structure specialization for .zip() iteratorUlrik Sverdrup-38/+31
Go back on half the specialization, the part that changed the Zip struct's fields themselves depending on the types of the iterators. This means that the Zip iterator will always carry two usize fields, which are unused. If a whole for loop using a .zip() iterator is inlined, these are simply removed and have no effect. The same improvement for Zip of for example slice iterators remain, and they still optimize well. However, like when the specialization of zip was merged, the compiler is still very sensistive to the exact context. For example this code only autovectorizes if the function is used, not if the code in zip_sum_i32 is inserted inline it was called: ``` fn zip_sum_i32(xs: &[i32], ys: &[i32]) -> i32 { let mut s = 0; for (&x, &y) in xs.iter().zip(ys) { s += x * y; } s } fn zipdot_i32_default_zip(b: &mut test::Bencher) { let xs = vec![1; 1024]; let ys = vec![1; 1024]; b.iter(|| { zip_sum_i32(&xs, &ys) }) } ``` Include a test that checks that Zip<T, U> is covariant w.r.t. T and U.

2016-09-12memrchr: Use a conditional instead of subtracting a complicated minUlrik Sverdrup-1/+1
This makes the critical calculation easier to understand.
2016-09-12memrchr: Correct aligned offset computationUlrik Sverdrup-1/+23
The memrchr fallback did not compute the offset correctly. It was intentioned to land on usize-aligned addresses but did not. This was suspected to resulted in a crash on ARMv7 platform! This bug affected non-linux platforms. I think like this, if we have a slice with pointer `ptr` and length `len`, we want to find the last usize-aligned offset in the slice. The correct computation should be: For example if ptr = 1 and len = 6, and size_of::<usize>() is 4: [ x x x x x x ] 1 2 3 4 5 6 ^-- last aligned address at offset 3 from the start. The last aligned address is ptr + len - (ptr + len) % usize_size. Compute offset from the start as: offset = len - (ptr + len) % usize_size = 6 - (1 + 6) % 4 = 6 - 3 = 3. I believe the function's return value was always correct previously, if the platform supported unaligned addresses.
