The data structure was originally added in
41e1cd185b82a518c58c92544c45f0348c03ef74 and then removed in
50a336fff899ebd8a687c453ec6beb18a5a9baf9, but brought back in
711bf55eaa643c3d05640bebbf3e4315477b8ed8 for Decl in the compiler
frontend, and then the last reference to it was eliminated in
548a087fafeda5b07d2237d5137906b8d07da699 which removed Decl in favor of
Nav and Cau.

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.

Follow up to #19079, which made test names fully qualified.
This fixes tests that now-redundant information in their test names. For example here's a fully qualified test name before the changes in this commit:
"priority_queue.test.std.PriorityQueue: shrinkAndFree"
and the same test's name after the changes in this commit:
"priority_queue.test.shrinkAndFree"

This reverts commit 0c99ba1eab63865592bb084feb271cd4e4b0357e, reversing
changes made to 5f92b070bf284f1493b1b5d433dd3adde2f46727.
This caused a CI failure when it landed in master branch due to a
128-bit `@byteSwap` in std.mem.

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

Closes #11787
|

There are still a few occurrences of "stage1" in the standard library
and self-hosted compiler source, however, these instances need a bit
more careful inspection to ensure no breakage.

Rather than allocating Decl objects with an Allocator, we instead allocate
them with a SegmentedList. This provides four advantages:
* Stable memory so that one thread can access a Decl object while another
thread allocates additional Decl objects from this list.
* It allows us to use u32 indexes to reference Decl objects rather than
pointers, saving memory in Type, Value, and dependency sets.
* Using integers to reference Decl objects rather than pointers makes
serialization trivial.
* It provides a unique integer to be used for anonymous symbol names,
avoiding multi-threaded contention on an atomic counter.
|
|
* Remove the Allocator field; instead it must be passed in as a
parameter to any function that needs it.
* Rename `push` to `append` and `pushMany` to `appendSlice` to match
the conventions set by ArrayList.

I want to use it for the self-hosted compiler.

I spent a long time working on this data structure, and I still think
it's a neat idea, but it has no business being in the std lib.
I'm aware of the few remaining references to SegmentedList that exist in
the std lib, but they are dead code, and so I'm leaving the dead
references as a clue that the code is dead. Cleaning up dead code will
be a separate effort that involves code coverage tools to make sure we
find it all.

This change was mostly made with `zig fmt` and this also modified some whitespace. Note that in some files, `zig fmt` produced incorrect code, so the change was made manually.

* Implements #3768. This is a sweeping breaking change that requires
many (trivial) edits to Zig source code. Array values no longer
coerced to slices; however one may use `&` to obtain a reference to
an array value, which may then be coerced to a slice.
* Adds `IrInstruction::dump`, for debugging purposes. It's useful to
call to inspect the instruction when debugging Zig IR.
* Fixes bugs with result location semantics. See the new behavior test
cases, and compile error test cases.
* Fixes bugs with `@typeInfo` not properly resolving const values.
* Behavior tests are passing but std lib tests are not yet. There
is more work to do before merging this branch.

std.heap.direct_allocator is still available for now but it is marked
deprecated.

that's all this commit does. further commits will fix cli flags and
such.
