* Every decl provides a 16 byte source hash which can be used to detect
if the source code for any particular decl has changed.
* Include comptime decls, test decls, and usingnamespace decls in the
decls list of namespaces.
- Tests are encoded as extended functions with is_test bit set.
Notably this exposed an issue with the language having to do with the
secret safety tag on untagged unions. How can we have our cake and eat
it too? Not solved in this commit. I will file a language proposal to
tackle this issue soon.
Fixes a compile error in `std.fs.File.readvAll`.
Inside a nosuspend block, emit function calls as nosuspend calls.
Also inside a comptime block, emit function calls as comptime calls.
Also emit `async foo()` calls as async calls.
Remove compile error for `nosuspend` block inside `suspend` block.
Instead of implicitly treating every `suspend` block also as a
`nosuspend` block (which would make sense), we leave suspension points
as compile errors, to hint to the programmer about accidents. Of course
they may then assert `nosuspend` by introducing a block within their
suspend block.
To make room in `Zir.Inst.Tag` I moved `typeof_peer` and `compile_log`
to `Extended`.
* AstGen: implement `anyframe_literal` and `anyframe_type`.
* Introduce `makeSubBlock` to avoid redundant AstGen code for GenZir
scopes. Allows adding/removing a field without possibility of
accidentally introducing a bug of forgetting to set the new field.
* Add to GenZir `nosuspend_node` and `suspend_node` in preparation for
implementing `suspend` blocks and `nosuspend` blocks.
* AstGen: fix assembly to support clobbers, multiple outputs, and
outputs without `->` syntax.
- `asm` and `asm_volatile` move to `Extended` enum with `small` being
repurposed for a few things. This frees up 2 ZIR tags, 1 of which
is used in this commit and 1 is leftover.
* AstGen: fix `simple_types` incorrectly having multiple conflicting
values for "undefined" and "null".
- Also add "anyframe" to `simple_types`.
* Add `anyframe_type` to type.zig, value.zig and `Zir.Inst.Ref`.
- Also add i128 and u128 types to `Zir.Inst.Ref` and `simple_types`.
* Sema/Zir: Fix incorrect math causing the function body to be messed
up for Extended-encoded functions.
* Zir: support `i32` fields for "extra" payloads.
* `comptime const` is redundant
* don't use `extern enum`; specify a tag type.
`extern enum` is only when you need tags to alias. But aliasing tags
is a smell. I will be making a proposal shortly to remove `extern enum`
from the language.
* there is no such thing as `packed enum`.
* instead of `catch |_|`, omit the capture entirely.
* unused function definition with missing parameter name
* using `try` outside of a function or test
