By factoring out the comptime parts of this computation, vectors are no
longer useful in this function.
|
|
|
|
|
|
There are still a few occurrences of "stage1" in the standard library
and self-hosted compiler source, however, these instances need a bit
more careful inspection to ensure no breakage.
|

closes #13535
|
|
Vectors are not yet implemented in the C backend, so no reason to
prevent code using the standard library from compiling in the meantime.
|
|
See #3811
|
|
The miscompilation in question has been fixed upstream in LLVM 13.
closes #8117

Adds error for taking a non comptime parameter in a function returning a
comptime-only type but not when that type is dependent on a parameter.

Update basic usage test to account for these, and by extension for addOneAssumeCapacity.
|
|
Ever since a semi-recent language specification update, pointers to
zero-sized types still have runtime bits.

This also adds `std.sort.sortContext` and
`std.sort.insertionSortContext` which are more advanced methods that
allow overriding the `swap` method. The former calls the latter for now
because reworking the main sort implementation is a big task that can be
done later without any changes to the API.

This reverts commit 1f10cf4edf2b645e63dedc42f5d7475914bf2311.
Re-opens #10618
I want to solve this a different way. `align(S)` where S is a 0-byte
type should work in this context.
This also caused issues such as
https://github.com/Vexu/arocc/issues/221

Also fixes error with ArrayHashMap when both key and value are 0 sized

Calling `insert` on a `std.MultiArrayList` currently fails with a compiler error due to using a `try` without the `!` annotation on the return type
```zig
this.list.insert(allocator, 0, listener);
```
```zig
/Users/jarred/Build/zig/lib/std/multi_array_list.zig:192:13: error: expected type 'void', found '@typeInfo(@typeInfo(@TypeOf(std.multi_array_list.MultiArrayList(src.javascript.jsc.node.types.Listener).ensureUnusedCapacity)).Fn.return_type.?).ErrorUnion.error_set'
try self.ensureUnusedCapacity(gpa, 1);
```

We already have a LICENSE file that covers the Zig Standard Library. We
no longer need to remind everyone that the license is MIT in every single
file.
Previously this was introduced to clarify the situation for a fork of
Zig that made Zig's LICENSE file harder to find, and replaced it with
their own license that required annual payments to their company.
However that fork now appears to be dead. So there is no need to
reinforce the copyright notice in every single file.

- hash/eql functions moved into a Context object
- *Context functions pass an explicit context
- *Adapted functions pass specialized keys and contexts
- new getPtr() function returns a pointer to value
- remove functions renamed to fetchRemove
- new remove functions return bool
- removeAssertDiscard deleted, use assert(remove(...)) instead
- Keys and values are stored in separate arrays
- Entry is now {*K, *V}, the new KV is {K, V}
- BufSet/BufMap functions renamed to match other set/map types
- fixed iterating-while-modifying bug in src/link/C.zig

Master branch added `try` to a bunch of testing function calls, and some
lines also had changed how to refer to the native architecture and other
`@import("builtin")` stuff.

Same as c8ae581fef6506a8234cdba1355ba7f0f449031a, but for
MultiArrayList.

Closes #8211

Reverts bf642204b373e01314ecfb0c50a643dc4b05746f and uses a different
workaround, suggested by @LemonBoy.
There is either a compiler bug or a design flaw somewhere around here.
It does not have to block this branch, but I need to understand exactly
what's going on here and make it so that nobody ever has to run into
this problem again.

Also known as "Struct-Of-Arrays" or "SOA". The purpose of this data
structure is to provide a similar API to ArrayList but instead of
the element type being a struct, the fields of the struct are in N
different arrays, all with the same length and capacity.
Having this abstraction means we can put them in the same allocation,
avoiding overhead with the allocator. It also saves a tiny bit of
overhead from the redundant capacity and length fields, since each
struct element shares the same value.
This is an alternate implementation to #7854.
