This reverts commit 93f0bcb649087b5db5cfcba5de5faaaf59047751.
This is not correct (from #mingw-w64 IRC):
<andrewrk> is there no .def file for ntdll on arm 64 bit?
<andrewrk> or does mingw-w64-crt/lib64/ntdll.def apply to both x86_64
and aarch64?
<wbs> andrewrk: there's none at the moment (as apps rarely link directly
against ntdll, and I didn't want to guess needlessly around that one
originally when I added arm64 support, before I actually had a real
arm64 windows device)
<wbs> andrewrk: but I guess I could/should complete that now
<wbs> (if you need one right now, the libarm32 one probably is the
closest match)
* anonymous decls have automatically generated names and symbols, and
participate in the same memory management as named decls.
* the Ref instruction is deleted
* the DeclRef instruction now takes a `[]const u8` and DeclRefStr takes
an arbitrary string instruction operand.
* introduce a `zir.Decl` type for ZIR Module decls which holds
content_hash and name - fields that are not needed for `zir.Inst`
which are created as part of semantic analysis. This improves the
function signatures of Module.zig and lowers memory usage.
* the Str instruction is now defined to create an anonymous Decl and
reference it.
This commit generalizes `std.fs.wasi.PreopenList.find(...)` allowing
search by `std.fs.wasi.PreopenType` union type rather than by dir
name. In the future releases of WASI, it is expected to have more
preopen types (or capabilities) than just directories. This commit
aligns itself with that vision.
This is a potentially breaking change. However, since `std.fs.wasi.PreopenList`
wasn't made part of any Zig release yet, I think we should be OK
to introduce those changes without pointing to any deprecations.
This commit adds some unit tests for `std.fs.File.readAllAlloc`
function. It also updates the docs of `Reader.readNoEof`
which were outdated, and swaps `inStream()` for `reader()` in
`File.readAllAlloc` with the former being deprecated.
Adds Windows stub (still needs to be implemented on Windows),
adds WASI implementation, adds unit test testing basic chain of
ops: create file -> symlink -> readlink.
zig fmt previously would write a temp file, and then either rename it
into place if necessary, or unlink it if nothing was changed. Now zig
fmt renders into a memory buffer, and only writes the temp file and
renames it into place if anything changed.
Based on the performance testing I did this actually did not have much
of an impact, however it's likely that on other operating systems and
other hard drives this could make a big difference.
* `std.fs.Dir.Entry.Kind` is moved to `std.fs.File.Kind`
* `std.fs.File.Stat` gains the `kind` field, so performing a stat() on
a File now tells what kind of file it is. On Windows this only will
distinguish between directories and files.
* rework zig fmt logic so that in the case of opening a file and
discovering it to be a directory, it closes the file descriptor
before re-opening it with O_DIRECTORY, using fewer simultaneous open
file descriptors when walking a directory tree.
* rework zig fmt logic so that it pays attention to the kind of
directory entries, and when it sees a sub-directory it attempts to
open it as a directory rather than a file, reducing the number of
open() syscalls when walking a directory tree.
The original check for a directory was for the `readAllAlloc` so move the check from open to read. This in turn fixes the fmt step in the build script for directories.
