Too many bugs have been found with `truncate` at this point, so it was
rewritten from scratch.
Based on the doc comment, the utility of `convertToTwosComplement` over
`r.truncate(a, .unsigned, bit_count)` is unclear and it has a subtle
behavior difference that is almost certainly a bug, so it was deleted.
This commit allows using ZON (Zig Object Notation) in a few ways.
* `@import` can be used to load ZON at comptime and convert it to a
normal Zig value. In this case, `@import` must have a result type.
* `std.zon.parse` can be used to parse ZON at runtime, akin to the
parsing logic in `std.json`.
* `std.zon.stringify` can be used to convert arbitrary data structures
to ZON at runtime, again akin to `std.json`.
Closes#21311
The sign of the result `r` needs to be initialized before the correction
`r.addScalar(r.toConst(), -1)`, or the intended end result could be off
by 2 (depending on the original sign of `r`).
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.
* 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
All of the std except these few functions call it "eql" instead of "eq".
This has previously tripped me up when I expected the equality check function to be called "eql"
(just like all the rest of the std) instead of "eq".
The motivation is consistency.
If search "eq" on Autodoc, these functions stick out and it looks inconsistent.
I just noticed there are also a few functions spelling it out as "equal" (such as std.mem.allEqual).
Maybe those functions should also spell it "eql" but that can be done in a future PR.
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
- `bytes` -> `buffer`
- Correct naming consistency between
1. fn argument and doc comment of `(read|write)PackedTwosComplement`
2. fn arguments of `(read|write)PackedTwosComplement` and `(read|write)TwosComplement`
The majority of these are in comments, some in doc comments which might
affect the generated documentation, and a few in parameter names -
nothing that should be breaking, however.
When a big.Int.Mutable had more than two limbs, it was possible for
this function to change the `len` field without zeroing limbs in the
active range. These uninitialized limbs would then be used in
`truncate()` and could cause invalid results.
Closes#13571
This pull request removes the optional allocator argument from functions
`divFloor` and `divTrunc`. As a result, the comments related to accepting an
optional `allocator` are no longer applicable. The support for accepting
an optional allocator was removed in #10017.
