Like ELF, we now have `std.debug.MachOFile` for the host-independent
parts, and `std.debug.SelfInfo.MachO` for logic requiring the file to
correspond to the running program.
|
|
This is the logic that LLD uses. It is pretty silly, but it is what it is.

std.fmt.Formatter -> std.fmt.Alt
std.fmt.format -> std.Io.Writer.print
|

and delete deprecated alias std.io

Embrace the Path abstraction, doing more operations based on directory
handles rather than absolute file paths. Most of the diff noise here
comes from this one.
Fix sorting of crtbegin/crtend atoms. Previously it would look at all
path components for those strings.
Make the C runtime path detection partially a pure function, and move
some logic to glibc.zig where it belongs.

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 avoids mixing preads with reads which do not mix well especially
on Windows.

Deprecated aliases that are now compile errors:
- `std.fs.MAX_PATH_BYTES` (renamed to `std.fs.max_path_bytes`)
- `std.mem.tokenize` (split into `tokenizeAny`, `tokenizeSequence`, `tokenizeScalar`)
- `std.mem.split` (split into `splitSequence`, `splitAny`, `splitScalar`)
- `std.mem.splitBackwards` (split into `splitBackwardsSequence`, `splitBackwardsAny`, `splitBackwardsScalar`)
- `std.unicode`
+ `utf16leToUtf8Alloc`, `utf16leToUtf8AllocZ`, `utf16leToUtf8`, `fmtUtf16le` (all renamed to have capitalized `Le`)
+ `utf8ToUtf16LeWithNull` (renamed to `utf8ToUtf16LeAllocZ`)
- `std.zig.CrossTarget` (moved to `std.Target.Query`)
Deprecated `lib/std/std.zig` decls were deleted instead of made a `@compileError` because the `refAllDecls` in the test block would trigger the `@compileError`. The deleted top-level `std` namespaces are:
- `std.rand` (renamed to `std.Random`)
- `std.TailQueue` (renamed to `std.DoublyLinkedList`)
- `std.ChildProcess` (renamed/moved to `std.process.Child`)
This is not exhaustive. Deprecated aliases that I didn't touch:
+ `std.io.*`
+ `std.Build.*`
+ `std.builtin.Mode`
+ `std.zig.c_translation.CIntLiteralRadix`
+ anything in `src/`

Support linking against tbd-v3 SDKs such as those bundled with
Xcode 10.3 → 11.3.1 .
- Map target os=`ios` and abi=`macabi` to macho.PLATFORM.MACCATALYST.
This allows for matches against tbdv4 targets, eg. `x86_64-maccatalyst`.
- When parsing old tbdv3 files with `zippered` platform, we append
[`ARCH-macos`, `ARCH-maccatalyst`] to list of "tbd" targets. This
enables linking for standard targets like `ARCH-macos-none` and
maccatalyst targets `ARCH-ios-macabi`.
- Update mappings for macho platform and zig target macabi. While this
is not full maccatalyst support, a basic exe can be built as follows:
```
zig libc > libc.txt
zig build-exe z0.zig --libc libc.txt -target x86_64-ios-macabi
```
closes #19110

Turns out that around 10.13/10.14 macOS release version, Apple changed the target tags in
tbd files from `macosx` to `macos`. In order to be compliant and therefore actually support
linking on older platforms against `libSystem.tbd`, we add `<cpu_arch>-macosx` to target strings.

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
|
|
Everywhere that can now use `splitScalar` should get a nice little performance boost.
