std/crypto: add chacha20
 2018-08-28 16:07:58 -04:00
Marc Tiehuis
87eb95f816 speed up chacha20 
The main changes are:

    Unrolling the inner rounds of salsa20_wordtobyte which doubles the speed.
    Passing the slice explicitly instead of returning the array saves a copy (can optimize out in future with copy elision) and gives ~10% improvement.
    Inlining the outer loop gives ~15-20% improvement but it costs an extra 4Kb of code space. I think the tradeoff is worthwhile here.
    The other inline loops are small and can be done by the compiler if it is worthwhile.
    The rotate function replacement doesn't alter the performance from the former.

The modified throughput test I've used to benchmark is as follows. Interestingly we need to allocate memory instead of using a fixed buffer else Zig optimizes the whole thing out.

ecc5464024 Handle unions differently in std.fmt (#1432) 
* Handle unions differently in std.fmt

Print the active tag's value in tagged unions. Untagged unions considered unsafe to print and treated like a pointer or an array.

Fixed compile error when passing enum to fmt 
Caused by struct printing behavior. Enums are different enough from structs and unions that the field iteration behavior doesn't do what we want even if @memberName didn't error on enums.

5c1ec20c9a MacOS stack traces use the already mmapped executable 
...rather than trying to find the executable on the file system.

Also use a more robust PIE offset calculation based on the
available metadata.

And for the last function, use the data that tells the end
rather than assuming 4K.

Also they print in a consistent way with Linux stack traces.

53b18b0791 Add secureZero function 
This is identical to `mem.set(u8, slice, 0)` except that it will never
be optimized out by the compiler. Intended usage is for clearing
secret data.

The resulting assembly has been manually verified in --release-* modes.

It would be valuable to test the 'never be optimized out' claim in tests
but this is harder than initially expected due to how much Zig appears
to know locally. May be doable with @intToPtr, @ptrToInt to get around
known data dependencies but I could not work it out right now.

fixed handling of [*]u8 when no format specifier is set 
If fmt was called on with a [*]u8 or [*]const u8 argument, but the fmt string did not specify 's' to treat it as a string, it produced a compile error due to accessing index 1 of a 0 length slice.

    value: i32,
};

fn number(node: *rb.Node) *Number {
    @fieldParentPtr(Number, "node", node);
}

fn compare(l: *rb.Node, r: *rb.Node) rb.Compare {
    var left = number(l);
    var right = number(r);

    if (left.value < right.value) {
        return rb.Compare.LessThan;
    } else if (left.value == right.value) {
        return rb.Compare.Equal;
    } else if (left.value > right.value) {
        return rb.Compare.GreaterThan;
    }
    unreachable;
}

A version that caches rb.Tree.first() could be added in the future.

std.io: PeekStream and SliceStream 
SliceStream is a read-only stream wrapper around a slice of bytes. It
allows adapting algorithms which work on InStreams to in-memory data.

PeekStream is a stream wrapper which allows "putting back" bytes into
the stream so that they can be read again. This will help make
look-ahead parsers easier to write.

a3f55aaf34 add event loop Channel abstraction 
This is akin to channels in Go, except:
 * implemented in userland
 * they are lock-free and thread-safe
 * they integrate with the userland event loop

The self hosted compiler is changed to use a channel for events,
and made to stay alive, watching files and performing builds when
things change, however the main.zig file exits after 1 build.

Note that nothing is actually built yet, it just parses the input
and then declares that the build succeeded.

Next items to do:
 * add windows and macos support for std.event.Loop
 * improve the event loop stop() operation
 * make the event loop multiplex coroutines onto kernel threads
 * watch source file for updates, and provide AST diffs
   (at least list the top level declaration changes)
 * top level declaration analysis

fd75e73ee9 add f16 type 
Add support for half-precision floating point operations.

Introduce `__extendhfsf2` and `__truncsfhf2` in std/special/compiler_rt.

Add `__gnu_h2f_ieee` and `__gnu_f2h_ieee` as aliases that are used in
Windows builds.

The logic in std/special/compiler_rt/extendXfYf2.zig has been reworked
and can now operate on 16 bits floating point types.

`extendXfYf2()` and `truncXfYf2()` are marked `inline` to work around
a not entirely understood stack alignment issue on Windows when calling
the f16 versions of the builtins.

dc8bda7e02 Add arbitrary-precision integer to std 
A few notes on the implementation:

 - Any unsigned power of two integer type less than 64 bits in size is supported
 as a Limb type.
 - The algorithms used are kept simple for the moment. More complicated
 algorithms are generally only more useful as integer sizes increase a
 lot and I don't expect our current usage to be used for this purpose
 just yet.
 - All branches (practically) have been covered by tests.

See 986a2b3243/bench
for rough performance comparison numbers.

Closes #364.

Before 1.0.0 we might remove some of this API, because you can use
`toSlice()` for everything, but it's ok to add these functions as
an experiment before then.

Also, remove `Json` from Parser names. The namespace `json` is sufficient.

f06bce5dda introduce [*] for unknown length pointers 
See #770

Currently it does not have any different behavior than `*`
but it is now recommended to use `[*]` for unknown length
pointers to be future-proof.

Instead of [ * ] being separate tokens as the proposal
suggested, this commit implements `[*]` as a single token.

fcbb7426fa use * for pointer type instead of & 
See #770

To help automatically translate code, see the
zig-fmt-pointer-reform-2 branch.

This will convert all & into *. Due to the syntax
ambiguity (which is why we are making this change),
even address-of & will turn into *, so you'll have
to manually fix thes instances. You will be guaranteed
to get compile errors for them - expected 'type', found 'foo'
