fcf88b8f87 coretest: Ensure that pointer formatting flags are cleaned up 2014-09-09 20:34:41 +01:00
Piotr Czarnecki
5aaa606932 Optimize for the most common cases of format!
Format specs are ignored and not stored in case they're all default.
Restore default formatting parameters during iteration.
Pass `None` instead of empty slices of format specs to take advantage
of non-nullable pointer optimization.

Generate a call to one of two functions of `fmt::Argument`.

9639cafd36 fixes for Box<[T]>
The pointer in the slice must not be null, because enum representations
make that assumption. The `exchange_malloc` function returns a non-null
sentinel for the zero size case, and it must not be passed to the
`exchange_free` lang item.

Since the length is always equal to the true capacity, a branch on the
length is enough for most types. Slices of zero size types are
statically special cased to never attempt deallocation. This is the same
implementation as `Vec<T>`.

Closes #14395

rand: inform the optimiser that indexing is never out-of-bounds.

This uses a bitwise mask to ensure that there's no bounds checking for
the array accesses when generating the next random number. This isn't
costless, but the single instruction is nothing compared to the branch.

A `debug_assert` for "bounds check" is preserved to ensure that
refactoring doesn't accidentally break it (i.e. create values of `cnt`
that are out of bounds with the masking causing it to silently wrap-
around).

Before:

test test::rand_isaac   ... bench: 990 ns/iter (+/- 24) = 808 MB/s
test test::rand_isaac64 ... bench: 614 ns/iter (+/- 25) = 1302 MB/s

After:

test test::rand_isaac   ... bench: 877 ns/iter (+/- 134) = 912 MB/s
test test::rand_isaac64 ... bench: 470 ns/iter (+/- 30) = 1702 MB/s

(It also removes the unsafe code in Isaac64Rng.next_u64, with a *gain*
in performance; today is a good day.)

The performance hit from these checks is significant, but unoptimized
builds are already incredibly slow. Enabling these checks results in
better test coverage since there are bots doing unoptimized builds, and
the cost is relatively small in the context of an unoptimized build.
This also allows using `JEMALLOC_FLAGS` to override the default
configure flags.

eb678ff87f librustc: Change the syntax of subslice matching to use postfix ..
instead of prefix `..`.

This breaks code that looked like:

    match foo {

    }

Change this code to:

    match foo {
        [ first, middle.., last ] => { ... }

325808a33d auto merge of #16952 : alexcrichton/rust/windows-large-console-write, r=brson
I've found that 64k is still too much and continue to see the errors as reported
in #14940. I've locally found that 32k fails, and 24k succeeds, so I've trimmed
the size down to 10000 which the included links in the added comment end up
recommending.

It sounds like the limit can still be hit with many threads in play, but I have
yet to reproduce this, so I figure we can wait until that's hit (if it's
possible) and then take action.

I've found that 64k is still too much and continue to see the errors as reported

the size down to 8192 which libuv happens to use as well.

22179f49e5 librustc: Feature gate subslice matching in non-tail positions.
This breaks code that uses the `..xs` form anywhere but at the end of a
slice. For example:

    match foo {
        [ 1, ..xs, 2 ]
        [ ..xs, 1, 2 ]
    }

Add the `#![feature(advanced_slice_patterns)]` gate to reenable the
syntax.

RFC #54.

Closes #16951.

3ca53d3a10 librustc: Make sure lifetimes in for loop heads outlive the for loop
itself.

This breaks code like:

    for &x in my_vector.iter() {
        my_vector[2] = "wibble";
        ...
    }

Change this code to not invalidate iterators. For example:

    for i in range(0, my_vector.len()) {
        my_vector[2] = "wibble";
        ...
    }

The `for-loop-does-not-borrow-iterators` test for #8372 was incorrect
and has been removed.

Closes #16820.

This was inspired by seeing a LLVM flatline of **~600MB** when running rustc with jemalloc (each type's `t_box_` is allocated on the heap, creating a lot of fragmentation, which jemalloc can deal with, unlike glibc).
