This implements the semantics as discussed in today's compiler meeting,
where the alignment of pointers to fields of default-layout unions
cannot exceed the field's alignment.
Resolves: #15878
Most of this migration was performed automatically with `zig fmt`. There
were a few exceptions which I had to manually fix:
* `@alignCast` and `@addrSpaceCast` cannot be automatically rewritten
* `@truncate`'s fixup is incorrect for vectors
* Test cases are not formatted, and their error locations change
The signature is `getOrCreateSubrange(int64_t Lo, int64_t Count)`, so this updates the bindings to match.
This fixes a crash in `lowerDebugTypeImpl` when analyzing slices that have a length of 2^32 or
larger (up to `2^64 >> 3`, which still crashes, because above that the array size in bits overflows u64).
Opaque and `noreturn` makes sense since they don't represent real
values, but `null` and `undefined` are perfectly normal
comptime-only values.
Closes#16088
The runCases function incorrectly called the introspect.findZigLibDir
function, causing a possible error, depending on the location of the
local cache directory, since the current executable is check-case.
Use findZigLibDirFromSelfExe, passing the zig_exe_path argument.
The current CI scripts work correctly because ZIG_LOCAL_CACHE_DIR is set
to "$(pwd)/zig-local-cache".
Fixes#15044
Make to avoid releasing request's connection twice.
Change the `Request.connection` field optional. This field is null while the connection is released.
Fixes#15965
I achieved this through a major refactor of the logic of analyzeMinMax.
This change should be compatible with vectors of comptime_int, which
Andrew said are supposed to work (but which currently do not).
We now resolve undefined symbols during incremental-compilation
where we discard the current symbol if we detect we found
an existing symbol which is not the one currently being updated.
The symbol will always be discarded in favor of the existing symbol
in such a case.
When lowering a decl value we verify whether its owner decl index
equals to the decl index of the decl being lowered. When this is not
the case, we are lowering an alias. So instead, we will now lower
the owner decl instead and call its symbol to ensure its type
is being correctly generated.
Calling into coercion logic here is a little opaque, and more to the
point wholly unnecessary. Instead, the (very short) logic is now
implemented directly in Sema.
