It's quite silly to have this override which nonetheless makes
assumptions about the input type. Encode the actual complexity of the
sort.
Also, simplify the sorting logic, and fix a bug (grab min and max
*after* the sort, not *before*!)
Most of these changes seem like improvements. The PDB thing had a TODO
saying it used to crash; I anticipate it works now, we'll see what CI
does.
The `std.os.uefi` field renames are a notable breaking change.
The compiler actually doesn't need any functional changes for this: Sema
does reification based on the tag indices of `std.builtin.Type` already!
So, no zig1.wasm update is necessary.
This change is necessary to disallow name clashes between fields and
decls on a type, which is a prerequisite of #9938.
This commit changes how we represent comptime-mutable memory
(`comptime var`) in the compiler in order to implement the intended
behavior that references to such memory can only exist at comptime.
It does *not* clean up the representation of mutable values, improve the
representation of comptime-known pointers, or fix the many bugs in the
comptime pointer access code. These will be future enhancements.
Comptime memory lives for the duration of a single Sema, and is not
permitted to escape that one analysis, either by becoming runtime-known
or by becoming comptime-known to other analyses. These restrictions mean
that we can represent comptime allocations not via Decl, but with state
local to Sema - specifically, the new `Sema.comptime_allocs` field. All
comptime-mutable allocations, as well as any comptime-known const allocs
containing references to such memory, live in here. This allows for
relatively fast checking of whether a value references any
comptime-mtuable memory, since we need only traverse values up to
pointers: pointers to Decls can never reference comptime-mutable memory,
and pointers into `Sema.comptime_allocs` always do.
This change exposed some faulty pointer access logic in `Value.zig`.
I've fixed the important cases, but there are some TODOs I've put in
which are definitely possible to hit with sufficiently esoteric code. I
plan to resolve these by auditing all direct accesses to pointers (most
of them ought to use Sema to perform the pointer access!), but for now
this is sufficient for all realistic code and to get tests passing.
This change eliminates `Zcu.tmp_hack_arena`, instead using the Sema
arena for comptime memory mutations, which is possible since comptime
memory is now local to the current Sema.
This change should allow `Decl` to store only an `InternPool.Index`
rather than a full-blown `ty: Type, val: Value`. This commit does not
perform this refactor.
Searching GitHub indicated that the only use of these types in the wild is
support in getty-zig, and testing for that support. This eliminates 3 more uses
of usingnamespace from the standard library, and removes some unnecessarily
complex generic code.
Follow up to #19079, which made test names fully qualified.
This fixes tests that now-redundant information in their test names. For example here's a fully qualified test name before the changes in this commit:
"priority_queue.test.std.PriorityQueue: shrinkAndFree"
and the same test's name after the changes in this commit:
"priority_queue.test.shrinkAndFree"
Current implementation fails to handle the following enum
```zig
const E = enum {
X,
pub const X = 1;
}
```
because `@field(type, name)` prefers declarations over enum fields.
This way people can use `const` with a `std.EnumMap`
and be able to `getPtrAssertContains(...)` like the
would with a mutable `var` instance.
Aligns with the existing `getPtr(...)`/`getPtrConst(...)`
methods.
In general, I don't like the idea of std.meta.trait, and so I am
providing some guidance by deleting the entire namespace from the
standard library and compiler codebase.
My main criticism is that it's overcomplicated machinery that bloats
compile times and is ultimately unnecessary given the existence of Zig's
strong type system and reference traces.
Users who want this can create a third party package that provides this
functionality.
closes#18051
Seems like this restriction was actual when Ziglang had extern enums,
but now it's not neccessary and can be lifted. It was present since
original PR which introduced std.enums, https://www.github.com/ziglang/zig/pull/8171.

* Make `count` comptime_int instead of usize
With previous type, creating EnumIndexer for enum(usize) and enum(isize)
would cause compile error since `count` could not store maxInt(usize) + 1.
Now it can store it and reflects len field from std.builtin.Type.Array
(most common use case of count field inside std.enums functions is creating arrays).

* Add missing period in Stack's description
This looks fine in the source, but looks bad when seen on the documentation website.
* Correct documentation for attachSegfaultHandler()
The description for attachSegfaultHandler() looks pretty bad without indicating that the stuff at the end is code
* Added missing 'the's in Queue.put's documentation
* Fixed several errors in Stack's documentation
`push()` and `pop()` were not styled as code
There was no period after `pop()`, which looks bad on the documentation.
* Fix multiple problems in base64.zig
Both "invalid"s in Base64.decoder were not capitalized.
Missing period in documentation of Base64DecoderWithIgnore.calcSizeUpperBound.
* Fix capitalization typos in bit_set.zig
In DynamicBitSetUnmanaged.deinit's and DynamicBitSet.deinit's documentation, "deinitializes" was uncapitalized.
* Fix typos in fifo.zig's documentation
Added a previously missing period to the end of the first line of LinearFifo.writableSlice's documentation.
Added missing periods to both lines of LinearFifo.pump's documentation.
* Fix typos in fmt.bufPrint's documentation
The starts of both lines were not capitalized.
* Fix minor documentation problems in fs/file.zig
Missing periods in documentation for Permissions.setReadOnly, PermissionsWindows.setReadOnly, MetadataUnix.created, MetadataLinux.created, and MetadataWindows.created.
* Fix a glaring typo in enums.zig
* Correct errors in fs.zig
* Fixed documentation problems in hash_map.zig
The added empty line in verify_context's documentation is needed, otherwise autodoc for some reason assumes that the list hasn't been terminated and continues reading off the rest of the documentation as if it were part of the second list item.
* Added lines between consecutive URLs in http.zig
Makes the documentation conform closer to what was intended.
* Fix wrongfully ended sentence in Uri.zig
* Handle wrongly entered comma in valgrind.zig.
* Add missing periods in wasm.zig's documentation
* Fix odd spacing in event/loop.zig
* Add missing period in http/Headers.zig
* Added missing period in io/limited_reader.zig
This isn't in the documentation due to what I guess is a limitation of autodoc, but it's clearly supposed to be. If it was, it would look pretty bad.
* Correct documentation in math/big/int.zig
* Correct formatting in math/big/rational.zig
* Create an actual link to ZIGNOR's paper.
* Fixed grammatical issues in sort/block.zig
This will not show up in the documentation currently.
* Fix typo in hash_map.zig
Currently, the compiler (like @typeName) writes it `fn(...) Type` but
zig fmt writes it `fn (...) Type` (notice the space after `fn`).
This inconsistency is now resolved and function types are consistently
written the zig fmt way. Before this there were more `fn (...) Type`
occurrences than `fn(...) Type` already.
Most of this migration was performed automatically with `zig fmt`. There
were a few exceptions which I had to manually fix:
* `@alignCast` and `@addrSpaceCast` cannot be automatically rewritten
* `@truncate`'s fixup is incorrect for vectors
* Test cases are not formatted, and their error locations change
ccf670c made using `return` from within a comptime block in a non-inline
function illegal, since it is a use of runtime control flow in a
comptime block. It is allowed if the function in question is `inline`,
since no actual control flow occurs in this case. A few functions from
std (notably `std.fmt.comptimePrint`) needed to be marked `inline` to
support this change.
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.
