The names of these functions should probably change, but at least
the semantics are correct now:
* type_is_codegen_pointer - the type is either a fn, ptr, or promise
* get_codegen_ptr_type -
- ?&T and &T returns &T
- ?promise and promise returns promise
- ?fn()void and fn()void returns fn()void
- otherwise returns nullptr
Allow implicit casts from container types to nullable const pointers to
said container type. That is:
fn f() void {
const s = S {};
g(s); // Works.
g(&s); // So does this.
}
fn g(_: ?&const S) void { // Nullable const pointer.
}
Fixes#731.
Add basic address->symbol resolution support. Uses symtab data from the
MachO image, not external dSYM data; that's left as a future exercise.
The net effect is that we can now map addresses to function names but
not much more. File names and line number data will have to wait until
a future pull request.
Partially fixes#434.
Use std.heap.FixedBufferAllocator combined with
std.heap.DirectAllocator instead.
std.mem.FixedBufferAllocator is moved to std.heap.FixedBufferAllocator
* DirectAllocator does the underlying syscall for every allocation.
* ArenaAllocator takes another allocator as an argument and
allocates bytes up front, falling back to DirectAllocator with
increasingly large allocation sizes, to avoid calling it too often.
Then the entire arena can be freed at once.
The self hosted parser is updated to take advantage of ArenaAllocator
for the AST that it returns. This significantly reduces the complexity
of cleanup code.
docgen and build runner are updated to use the combination of
ArenaAllocator and DirectAllocator instead of IncrementingAllocator,
which is now deprecated in favor of FixedBufferAllocator combined
with DirectAllocator.
The C allocator calls aligned_alloc instead of malloc, in order to
respect the alignment parameter.
Added asserts in Allocator to ensure that implementors of the
interface return slices of the correct size.
Fixed a bug in Allocator when you call realloc to grow the allocation.
