* add TypedValue.Managed which represents a Type, a Value, and some
kind of memory management strategy.
* introduce an analysis queue
* flesh out how incremental compilation works with respect to exports
* ir.text.Module is only capable of one error message during parsing
* link.zig no longer has a decl table map and instead has structs that
exist directly on ir.Module.Decl and ir.Module.Export
* implement primitive .text block allocation
* implement linker code for updating Decls and Exports
* implement null Type
Some supporting std lib changes:
* add std.ArrayList.appendSliceAssumeCapacity
* add std.fs.File.copyRange and copyRangeAll
* fix std.HashMap having modification safety on in ReleaseSmall builds
* add std.HashMap.putAssumeCapacityNoClobber
* introduce std.ArrayListUnmanaged for when you have the allocator
stored elsewhere
* move std.heap.ArenaAllocator implementation to its own file. extract
the main state into std.heap.ArenaAllocator.State, which can be
stored as an alternative to storing the entire ArenaAllocator, saving
24 bytes per ArenaAllocator on 64 bit targets.
* std.LinkedList.Node pointer field now defaults to being null
initialized.
* Rework self-hosted compiler Package API
* Delete almost all the bitrotted self-hosted compiler code. The only bit
rotted code left is in main.zig and compilation.zig
* Add call instruction to ZIR
* self-hosted compiler ir API and link API are reworked to support
a long-running compiler that incrementally updates declarations
* Introduce the concept of scopes to ZIR semantic analysis
* ZIR text format supports referencing named decls that are declared
later in the file
* Figure out how memory management works for the long-running compiler
and incremental compilation. The main roots are top level
declarations. There is a table of decls. The key is a cryptographic
hash of the fully qualified decl name. Each decl has an arena
allocator where all of the memory related to that decl is stored.
Each code block has its own arena allocator for the lifetime of
the block. Values that want to survive when going out of scope in
a block must get copied into the outer block. Finally, values must
get copied into the Decl arena to be long-lived.
* Delete the unused MemoryCell struct. Instead, comptime pointers are
based on references to Decl structs.
* Figure out how caching works. Each Decl will store a set of other
Decls which must be recompiled when it changes.
This branch is still work-in-progress; this commit breaks the build.
This is not a meaningful abstraction. Use a for loop on the result
of `toSlice` or `toSliceConst`.
An iterator can be implemented on top of ArrayList by applications which
want additional functionality, such as removing elements while
iterating.
Closes#3037.
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.
Added ArrayList.initCapcity() as a way to preallocate a block of memory to reduce future allocations.
Added a test "std.ArrayList.initCapacity" that ensures initCapacity adds no elements and increases capacity by at least the requested amount
* Add some documentation for standard library things.
Added a bunch of descriptions for array_list.
Added some usage notes for failing_allocator.
Documented some of mem.Allocator.
