comptime T: type,

) std.meta.Vector(len, T)
Constructs a vector from a & b, based on the values in the predicate vector. For indices where the predicate value is true, the corresponding
element from the a vector is selected, and otherwise from b.
c_void is *not* simply `const c_void = opaque{};`. It has unique
semantics as any pointer type may coerce to `*c_void` which is not true
for an arbitrary `*opaque{}`.
The "Zig Test" section of the language reference has been moved between the
current "Hello World" section and the "Comments" section. This was done to
introduce the Zig test syntax before it is used in later sections.
The description of the Zig test feature has NOT been updated in this commit.
Closes#5837
This is for consistency with the documentation on sentinel-terminated
{arrays,slices,pointers} which already use `N` for a comptime-inferred
size rather than `X`.
Also adds a behavioral test to assert that a string literal is returned.
This was already the case, but the documentation failed to point out
that the returned value is of type `*const [N:0]u8`, i.e. that of a
string literal.
Also adds a behavioral test to assert that this is the case.
The Zig language specification will support identifiers and field access
in order to refer to which declaration to export with `@export`.
This commit implements the change in AstGen and updates the language
reference.
I want the language reference to be divorced from any particular
community. Also remove the call to action since the docs are
known to be incomplete and are not the current focus of the project.
Closes#9055
This matches the behaviour for other targets in that
```
zig build-lib math.zig -target wasm32-freestanding
```
produces now `libmath.a` while
```
zig build-lib math.zig -dynamic -target wasm32-freestanding
```
is required to create a loadable Wasm module.
This matches the behaviour of other languages and leaves us
the ability to create actual static Wasm archives with
```
zig build-lib -static some.zig
```
which can then be combined with other Wasm object files and linked
into either a Wasm lib or executable using `wasm-ld`.
Update langref to reflect the fact we now ship WASI libc.

Master branch added `try` to a bunch of testing function calls, and some
lines also had changed how to refer to the native architecture and other
`@import("builtin")` stuff.
Conflicts:
lib/std/crypto/25519/field.zig
lib/std/crypto/poly1305.zig
I had resolved those by removing `comptime` but master branch decided to
make the parameters `comptime`.
This also pulls in the updated default `zig build` install directory.
