This implements improvements/fixes to get all the union, tuple, and array behavior tests passing.
Previously, we lowered parent pointers for field_ptr and element_ptr incompletely. This has now
been improved to recursively lower such pointer.
Also a fix was done to `generateSymbol` when checking a container's layout.
Previously it was assumed to always be a struct. However, the type can also be a tuple, and therefore
panicking. Updating to ask a type's container layout instead allows us to keep a singular branch for both cases.
Example scenario:
test {
const a: i32 = blk: {
if (false) break :blk 24;
};
_ = a;
}
Prior to this, this would panic the compiler with a source needed error.
This provides the source as `sema.src`. This is not ideal, since the
line it points to is pretty far from the true issue. (One block out)
But, this prevents the compiler from straight up crashing and follows a
pattern used by similar ZIR which don't provide a src loc.
Add placeholder files for Codegen, Emit, and Mir stages, complete with
a placeholder implementation of generate() to make it able to be plugged in
to the frontend. At the moment the implementation just panics, it'll be
worked on incrementally later.
Also, this registers the sparcv9 backend files into CMakeLists.txt.
* Identify the ones that are passing and stop skipping them.
* Flatten out the main behavior.zig file and have each individual test
disable itself if it is not passing.
This function took a parameter that was only ever used with one value,
obscuring the fact that it was a regular `block` which should be used with
`.break` and not `.break_inline`.
* 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.
Instead of doing it before the switch tower, do it afterwards, so that
special handling may be done before undefined gets casted to the
destination type.
In this case the special handling we want to do is *[N]T to []T setting
the slice length based on the array length, even when the array value is
undefined.
