`stage2_spirv64` -> `stage2_spirv`
|
|
|
|
This rewrite improves some error messages, hugely simplifies the logic,
and fixes several bugs. One of these bugs is technically a new rule
which Andrew and I agreed on: if a parameter has a comptime-only type
but is not declared `comptime`, then the corresponding call argument
should not be *evaluated* at comptime; only resolved. Implementing this
required changing how function types work a little, which in turn
required allowing a new kind of function coercion for some generic use
cases: function coercions are now allowed to implicitly *remove*
`comptime` annotations from parameters with comptime-only types. This is
okay because removing the annotation affects only the call site.
Resolves: #22262

This also includes some compiler and std changes to correct error
messages which weren't properly updated before.
|
|
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.

Besides the Intel OpenCL CPU runtime, we can now run the
behavior tests using the Portable Computing Language. This
implementation is open-source, so it will be easier for us
to patch in updated versions of spirv-llvm-translator that
have bug fixes etc.

A pointer type already has an alignment, so this information does not
need to be duplicated on the function type. This already has precedence
with addrspace which is already disallowed on function types for this
reason. Also fixes `@TypeOf(&func)` to have the correct addrspace and
alignment.

Some tests are now failing due to debug info changes, some tests
now pass due to improved compiler functionality.
|
|
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.

Good riddance.

Closes #12910
|

This avoids the following confusing error message:
error: expected type 'fn(i32, i32) void', found 'fn(i32, i32) void'
|

This fixes a bug exposed by cd1833044ab7505bc101c85f59889bd3ea3fac80
where a function type would be converted to generic_poison even after
being instantiated due to containing comptime only types.
This could also be fixed by just checking `is_generic_instantiation`
but this way also provides better type names.
Closes #12625

All tests have been manually verified which are now passing. This means that any remaining
TODO is an actual to-be-fixed or to-be-implemented test case.

* make it always return a fully qualified name. stage1 is inconsistent
about this.
* AstGen: fix anon_name_strategy to correctly be `func` when anon type
creation happens in the operand of the return expression.
* Sema: implement type names for the "function" naming strategy.
* Put "enum", "union", "opaque", or "struct" in place of "anon" when
creating respective anonymous Decl names.
* std.testing: add `expectStringStartsWith`. Didn't end up using it
after all.
Also this enables the real test runner for stage2 LLVM backend (sans
wasm32) since it works now.

- generic "struct:L:C" naming if rloc is NodeTypeStructValueField
- generic "struct:L:C" naming if rloc is NodeTypeFnCallExpr
- move some tests from test/behavior/misc to test/behavior/typename

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.

And fix test cases to make them pass. This is in preparation for
starting to pass behavior tests with self-hosted.
