Tracked by #25684
|
|
got the build runner compiling
|
|
the ziglang/translate-c package has its own test suite, so these are
redundant
|
|
generic_function_returning_opaque_type.zig was salvaged as it's still worth
having.
|
|
backend=auto (now the default if backend is omitted) means to let the compiler
pick whatever backend it wants as the default. This is important for platforms
where we don't yet have a self-hosted backend, such as loongarch64.
Also purge a bunch of redundant target=native.
|
|
These were low value and unfocused tests. We already have coverage of the
important aspects of these tests elsewhere. Additionally, there was really no
need for these to have their own test harness.

Skips tests in test/cases/compile_errors.

This reverts commit 83960e0eb068f786c46c3fe559016e1e9faea3cd.
|
|
no active maintainer, and it's failing to lower some basic stuff
|
|
|
|
This struct is larger than 256 bytes and code that copies it
consistently shows up in profiles of the compiler.
|
|
e.g. `x86_64-windows.win10...win11_dt-gnu` -> `x86_64-windows-gnu`
When the OS version is the default this is redundant with checking the
default in the standard library.
|
|
For instance, the file 'cases/compile_errors/undeclared_identifier.zig'
now corresponds to test name 'compile_errors.undeclared_identifier'.
This is useful because you can now filter based on the case dirname
using `-Dtest-filter`.

chore(std.mem): Rename `trimLeft` and `trimRight` to `trimStart` and `trimEnd`
|
|
|
|
|
|
Rename `trimLeft` to `trimStart`, and `trimRight` to `trimEnd`.
`trimLeft` and `trimRight` functions remain as deprecated aliases for
these new names.
|
|
|
|
We now run incremental tests with `tools/incr-check.zig` (with the
actual cases being in `test/incremental/`).

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`.

Acts as a replacement for `addSharedLibrary` and `addStaticLibrary`, but
linking mode can be changed more easily in build.zig, for example:
In library:
```zig
const linkage = b.option(std.builtin.LinkMode, "linkage", "Link mode for a foo_bar library") orelse .static; // or other default
const lib = b.addLibrary(.{
.linkage = linkage,
.name = "foo_bar",
.root_module = mod,
});
```
In consumer:
```zig
const dep_foo_bar = b.dependency("foo_bar", .{
.target = target,
.optimize = optimize,
.linkage = .static // or dynamic
});
mod.linkLibrary(dep_foor_bar.artifact("foo_bar"));
```
It also matches nicely with `linkLibrary` name.

Without doing this, we don't actually test whether the data layout string we
generate matches LLVM's.
A number of targets had to be commented out due to this change:
* Some are using a non-working experimental LLVM backend (arc, csky, ...).
* Some don't have working LLD support (lanai, sparc, ...).
* Some don't have working self-hosted linker support (nvptx).
* Some are using ABIs that haven't been standardized (loongarch32).
Finally, all non-x86 uefi targets are hopelessly broken and can't really be
fixed until we change our emit logic to lower *-uefi-* verbatim rather than to
*-windows-*. See: https://github.com/ziglang/zig/issues/21630

Under some architecture/operating system combinations it is forbidden
to return a pointer from a merge, as these pointers must point to a
location at compile time. This adds a check for those cases when
returning a pointer from a block merge.

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.

I'm so sorry.
This commit was just meant to be making all types fully resolve by
queueing resolution at the moment of their creation. Unfortunately, a
lot of dominoes ended up falling. Here's what happened:
* I added a work queue job to fully resolve a type.
* I realised that from here we could eliminate `Sema.types_to_resolve`
if we made function codegen a separate job. This is desirable for
simplicity of both spec and implementation.
* This led to a new AIR traversal to detect whether any required type is
unresolved. If a type in the AIR failed to resolve, then we can't run
codegen.
* Because full type resolution now occurs by the work queue job, a bug
was exposed whereby error messages for type resolution were associated
with the wrong `Decl`, resulting in duplicate error messages when the
type was also resolved "by" its owner `Decl` (which really *all*
resolution should be done on).
* A correct fix for this requires using a different `Sema` when
performing type resolution: we need a `Sema` owned by the type. Also
note that this fix is necessary for incremental compilation.
* This means a whole bunch of functions no longer need to take `Sema`s.
* First-order effects: `resolveTypeFields`, `resolveTypeLayout`, etc
* Second-order effects: `Type.abiAlignmentAdvanced`, `Value.orderAgainstZeroAdvanced`, etc
The end result of this is, in short, a more correct compiler and a
simpler language specification. This regressed a few error notes in the
test cases, but nothing that seems worth blocking this change.
Oh, also, I ripped out the old code in `test/src/Cases.zig` which
introduced a dependency on `Compilation`. This dependency was
problematic at best, and this code has been unused for a while. When we
re-enable incremental test cases, we must rewrite their executor to use
the compiler server protocol.

Adds a missing call to addLazyPathDependenciesOnly in
std.Build.Module.addCSourceFiles. Also fixes an issue in
std.Build.Step.WriteFile where it wasn't updating all the GeneratedFile
instances for every directory. To fix the second issue, I removed
all the GeneratedFile instances and now all files/directories reference
the steps main GeneratedFile via sub paths.

closes #20077

You don't know if it's possible to run a binary until you try. The build
system already integrates with executors and has the
`skip_foreign_checks` for exactly this use case.

writeFile was deprecated in favor of writeFile2 in f645022d16361865e24582d28f1e62312fbc73bb. This commit renames writeFile2 to writeFile and makes writeFile2 a compile error.

this patch renames ComptimeStringMap to StaticStringMap, makes it
accept only a single type parameter, and return a known struct type
instead of an anonymous struct. initial motivation for these changes
was to reduce the 'very long type names' issue described here
https://github.com/ziglang/zig/pull/19682.
this breaks the previous API. users will now need to write:
`const map = std.StaticStringMap(T).initComptime(kvs_list);`
* move `kvs_list` param from type param to an `initComptime()` param
* new public methods
* `keys()`, `values()` helpers
* `init(allocator)`, `deinit(allocator)` for runtime data
* `getLongestPrefix(str)`, `getLongestPrefixIndex(str)` - i'm not sure
these belong but have left in for now incase they are deemed useful
* performance notes:
* i posted some benchmarking results here:
https://github.com/travisstaloch/comptime-string-map-revised/issues/1
* i noticed a speedup reducing the size of the struct from 48 to 32
bytes and thus use u32s instead of usize for all length fields
* i noticed speedup storing KVs as a struct of arrays
* latest benchmark shows these wall_time improvements for
debug/safe/small/fast builds: -6.6% / -10.2% / -19.1% / -8.9%. full
output in link above.

This commit adds several fixes and improvements for the Zig compiler
test harness.
1. -Dskip-translate-c option added for skipping the translate-c tests.
2. translate-c/run-translated-c tests in test/cases/* have been added to
the steps test-translate-c and test-run-translated-c. Closes #18224.
3. Custom name added to the CheckFile step for the translate-c step to
better communicate which test failed.
4. Test manifest key validation added to return an error if a manifest
contains an invalid key.
|
|
* make test names contain the fully qualified name
* make test filters match the fully qualified name
* allow multiple test filters, where a test is skipped if it does not
match any of the specified filters

std: make options a struct instance instead of a namespace

This also makes a long-overdue change of extracting common state from
Build into a shared Graph object.
Getting the semantics right for these flags turned out to be quite
tricky. In the end it works like this:
* The override only happens when the target is fully native, with no
additional query parameters, such as versions or CPU features added.
* The override affects the resolved Target but leaves the original Query
unmodified.
* The "is native?" detection logic operates on the original, unmodified
query. This makes it possible to provide invalid host target
information, causing confusing errors to occur. Don't do that.
There are some minor breaking changes to std.Build API such as the fact
that `b.zig_exe` is now moved to `b.graph.zig_exe`, as well as a handful
of other similar flags.
