The new CI images provided by GitHub no longer provide ninja.exe, so
this commit installs it explicitly, using the suggested method from
GitHub.
See https://github.com/actions/runner-images/issues/8343 for more
details.
Simplify wording and add some formatting in several locations.
Expand sentinel array tests to highlight (non-)handling of internal
sentinels.
Fix format of symbol names in function pointers example.
Clarify wording a bit on the builin atomic* documentation.
Remove the (second) builtin compileLog example that demonstrated a lack of
compileLog entries.
* langref: address comments from rohlem
Use "0-terminated" instead of "null-terminated".
Undo some changes that were not as clear an improvement as I though.
* langref: remove stray ""
Thanks to rohlem for spotting this typo.
previously, in the container view (the type of view that you see when
you look at `std` for example), when listing types and namespaces, we
would only show doc comments places on the direct child decl, which in
the case of the `std` namespace, for example, it's just a bunch of
re-exports.
now, if we don't find a direct doc comment, we chase indirection and
display doc comments placed directly on the definition, if any.
this is the precise priority order:
```
/// 1
pub const Foo = _Foo;
/// 2
const _Foo = struct {
//! 3
};
```
The numbers show the priority order for autodoc.
It is very common, and well-defined, for a pointer on one side of a C ABI
to have a different but compatible element type. Examples include:
- `char*` vs `uint8_t*` on a system with 8-bit bytes
- `const char*` vs `char*`
- `char*` vs `unsigned char*`
Without this flag, Clang would invoke UBSAN when such an extern
function was called.
Might be nice to file an upstream issue and find out if there is a more
precise way to disable the problematic check.
`-fsanitize-cfi-icall-generalize-pointers` looks promising according to
the documentation, but empirically it does not work.
release/17.x branch, commit 8f4dd44097c9ae25dd203d5ac87f3b48f854bba8
This adds the flag `-D_LIBCPP_PSTL_CPU_BACKEND_SERIAL`. A future
enhancement could possibly pass something different if there is a
compelling parallel implementation. That libdispatch one might be worth
looking into.
* some manual fixes to generated CPU features code. in the future it
would be nice to make the script do those automatically. I suspect
the sm_90a thing is a bug in LLVM.
* add liteos to various target OS switches. I know nothing about this
OS; someone will need to work specifically on support for this OS
when the time comes to support it properly in zig.
* while waiting for the compiler, I went ahead and made more
conservative choices about when to use `inline` in std/Target.zig
Currently, the compiler (like @typeName) writes it `fn(...) Type` but
zig fmt writes it `fn (...) Type` (notice the space after `fn`).
This inconsistency is now resolved and function types are consistently
written the zig fmt way. Before this there were more `fn (...) Type`
occurrences than `fn(...) Type` already.
