zig/lib/libc/include/x86_64-macos.10-none/sys/attr.h
Jakub Konka 5b813f1a2a Set macOS/iPhoneOS/tvOS/watchOS ABI to none (unspecified) by default 
Prior to this change we would assume the ABI for Apple targets to
be GNU which could result in subtle errors in LLVM emitting calls
to non-existent system libc provided functions such as `_sincosf`
which is a GNU extension and as such is not provided by macOS for example.
This would result in linker errors where the linker would not be
able to find the said symbol in `libSystem.tbd`.

With this change, we now correctly identify macOS (and other Apple
platforms) as having ABI `unknown` which translates to unspecified
in LLVM under-the-hood:

```
// main.ll
target triple = "aarch64-unknown-macos-unknown"
```

Note however that we never suffix the target OS with target version
such as `macos11` or `macos12` which means we fail to instruct LLVM
of potential optimisations provided by the OS such as the availability
of function `___sincosf_stret`. I suggest we investigate that in a
follow-up commit.

/*
* VOL_CAP_FMT_PERSISTENTOBJECTIDS: When set, the volume has object IDs
* that are persistent (retain their values even when the volume is
* unmounted and remounted), and a file or directory can be looked up
* by ID. Volumes that support VolFS and can support Carbon File ID
* references should set this bit.
*
* VOL_CAP_FMT_SYMBOLICLINKS: When set, the volume supports symbolic
* links. The symlink(), readlink(), and lstat() calls all use this
* symbolic link.
*
* VOL_CAP_FMT_HARDLINKS: When set, the volume supports hard links.
* The link() call creates hard links.
*
* VOL_CAP_FMT_JOURNAL: When set, the volume is capable of supporting
* a journal used to speed recovery in case of unplanned shutdown
* (such as a power outage or crash). This bit does not necessarily
* mean the volume is actively using a journal for recovery.
*
* VOL_CAP_FMT_JOURNAL_ACTIVE: When set, the volume is currently using
* a journal for use in speeding recovery after an unplanned shutdown.
* This bit can be set only if VOL_CAP_FMT_JOURNAL is also set.
*
* VOL_CAP_FMT_NO_ROOT_TIMES: When set, the volume format does not
* store reliable times for the root directory, so you should not
* depend on them to detect changes, etc.
*
* VOL_CAP_FMT_SPARSE_FILES: When set, the volume supports sparse files.
* That is, files which can have "holes" that have never been written
* to, and are not allocated on disk. Sparse files may have an
* allocated size that is less than the file's logical length.
*
* VOL_CAP_FMT_ZERO_RUNS: For security reasons, parts of a file (runs)
* that have never been written to must appear to contain zeroes. When
* this bit is set, the volume keeps track of allocated but unwritten
* runs of a file so that it can substitute zeroes without actually
* writing zeroes to the media. This provides performance similar to
* sparse files, but not the space savings.
*
* VOL_CAP_FMT_CASE_SENSITIVE: When set, file and directory names are
* case sensitive (upper and lower case are different). When clear,
* an upper case character is equivalent to a lower case character,
* and you can't have two names that differ solely in the case of
* the characters.
*
* VOL_CAP_FMT_CASE_PRESERVING: When set, file and directory names
* preserve the difference between upper and lower case. If clear,
* the volume may change the case of some characters (typically
* making them all upper or all lower case). A volume that sets
* VOL_CAP_FMT_CASE_SENSITIVE should also set VOL_CAP_FMT_CASE_PRESERVING.
*
* VOL_CAP_FMT_FAST_STATFS: This bit is used as a hint to upper layers
* (especially Carbon) that statfs() is fast enough that its results
* need not be cached by those upper layers. A volume that caches
* the statfs information in its in-memory structures should set this bit.
* A volume that must always read from disk or always perform a network
* transaction should not set this bit.
*
* VOL_CAP_FMT_2TB_FILESIZE: If this bit is set the volume format supports
* file sizes larger than 4GB, and potentially up to 2TB; it does not
* indicate whether the filesystem supports files larger than that.
*
* VOL_CAP_FMT_OPENDENYMODES: When set, the volume supports open deny
* modes (e.g. "open for read write, deny write"; effectively, mandatory
* file locking based on open modes).
*
* VOL_CAP_FMT_HIDDEN_FILES: When set, the volume supports the UF_HIDDEN
* file flag, and the UF_HIDDEN flag is mapped to that volume's native
* "hidden" or "invisible" bit (which may be the invisible bit from the
* Finder Info extended attribute).
*
* VOL_CAP_FMT_PATH_FROM_ID: When set, the volume supports the ability
* to derive a pathname to the root of the file system given only the
* id of an object. This also implies that object ids on this file
* system are persistent and not recycled. This is a very specialized
* capability and it is assumed that most file systems will not support
* it. Its use is for legacy non-posix APIs like ResolveFileIDRef.
*
* VOL_CAP_FMT_NO_VOLUME_SIZES: When set, the volume does not support
* returning values for total data blocks, available blocks, or free blocks
* (as in f_blocks, f_bavail, or f_bfree in "struct statfs"). Historically,
* those values were set to 0xFFFFFFFF for volumes that did not support them.
*
* VOL_CAP_FMT_DECMPFS_COMPRESSION: When set, the volume supports transparent
* decompression of compressed files using decmpfs.
*
* VOL_CAP_FMT_64BIT_OBJECT_IDS: When set, the volume uses object IDs that
* are 64-bit. This means that ATTR_CMN_FILEID and ATTR_CMN_PARENTID are the
* only legitimate attributes for obtaining object IDs from this volume and the
* 32-bit fid_objno fields of the fsobj_id_t returned by ATTR_CMN_OBJID,
* ATTR_CMN_OBJPERMID, and ATTR_CMN_PAROBJID are undefined.
*
* VOL_CAP_FMT_DIR_HARDLINKS: When set, the volume supports directory
* hard links.
*
* VOL_CAP_FMT_DOCUMENT_ID: When set, the volume supports document IDs
* (an ID which persists across object ID changes) for document revisions.
*
* VOL_CAP_FMT_WRITE_GENERATION_COUNT: When set, the volume supports write
* generation counts (a count of how many times an object has been modified)
*
* VOL_CAP_FMT_NO_IMMUTABLE_FILES: When set, the volume does not support
* setting the UF_IMMUTABLE flag.
*
* VOL_CAP_FMT_NO_PERMISSIONS: When set, the volume does not support setting
* permissions.
*
* VOL_CAP_FMT_SHARED_SPACE: When set, the volume supports sharing space with
* other filesystems i.e. multiple logical filesystems can exist in the same
* "partition". An implication of this is that the filesystem which sets
* this capability treats waitfor arguments to VFS_SYNC as bit flags.
*
* VOL_CAP_FMT_VOL_GROUPS: When set, this volume is part of a volume-group
* that implies multiple volumes must be mounted in order to boot and root the
* operating system. Typically, this means a read-only system volume and a
* writable data volume.

* style locks via vnop_advlock. This includes the O_EXLOCK and O_SHLOCK
* flags of the open(2) call.
*
* VOL_CAP_INT_EXTENDED_SECURITY: When set, the volume implements
* extended security (ACLs).
*
* VOL_CAP_INT_USERACCESS: When set, the volume supports the
* ATTR_CMN_USERACCESS attribute (used to get the user's access
* mode to the file).
*
* VOL_CAP_INT_MANLOCK: When set, the volume supports AFP-style
