While iterating over all files in tarball set root_dir in diagnostic if
there is single root in tarball. Will be used in package manager with
strip_components = 0 to find the root of the fetched package.
The 64-bit backend supports printing all floats up to 64-bits. The
128-bit continues to be used for larger values.
This backend is approximately ~3x faster. Code size is a little smaller
in the full table case and much smaller if using the samll tables.
The implementation uses the same code-paths, parameterized by a set of
tables and their pow5 implementations. We continue to use the same
rounding/formatting mechanisms. Initially I explored a separate
implementation, as upstream does this and has specific optimizations for
these paths but for simplicity we don't. The performance loss is small
enough at this point and keeping them combined keeps them in sync.
Closes#19264.
- Changed `modf_result` to `Modf` to better fit naming conventions
- Reworked `modf` to be far simpler and support all floating point types (as well as vectors) (I have done benchmarks and can confirm that the performance is roughly equivalent to the old implementation)
- Added more descriptive tests for modf
- Deprecated `modf32_result` and `modf64_result` in favor of `Modf(f32)` and `Modf(f64)` respectively
Now that `-femit-docs` includes all modules, including the builtin
module, in the generated source tarball, it makes sense to apply the
same logic to the std-docs server. std-docs constructs its own tarball,
so a different approach is needed to achieve the same end result.
This commit changes how we represent comptime-mutable memory
(`comptime var`) in the compiler in order to implement the intended
behavior that references to such memory can only exist at comptime.
It does *not* clean up the representation of mutable values, improve the
representation of comptime-known pointers, or fix the many bugs in the
comptime pointer access code. These will be future enhancements.
Comptime memory lives for the duration of a single Sema, and is not
permitted to escape that one analysis, either by becoming runtime-known
or by becoming comptime-known to other analyses. These restrictions mean
that we can represent comptime allocations not via Decl, but with state
local to Sema - specifically, the new `Sema.comptime_allocs` field. All
comptime-mutable allocations, as well as any comptime-known const allocs
containing references to such memory, live in here. This allows for
relatively fast checking of whether a value references any
comptime-mtuable memory, since we need only traverse values up to
pointers: pointers to Decls can never reference comptime-mutable memory,
and pointers into `Sema.comptime_allocs` always do.
This change exposed some faulty pointer access logic in `Value.zig`.
I've fixed the important cases, but there are some TODOs I've put in
which are definitely possible to hit with sufficiently esoteric code. I
plan to resolve these by auditing all direct accesses to pointers (most
of them ought to use Sema to perform the pointer access!), but for now
this is sufficient for all realistic code and to get tests passing.
This change eliminates `Zcu.tmp_hack_arena`, instead using the Sema
arena for comptime memory mutations, which is possible since comptime
memory is now local to the current Sema.
This change should allow `Decl` to store only an `InternPool.Index`
rather than a full-blown `ty: Type, val: Value`. This commit does not
perform this refactor.
This extension to the typical `<>` Markdown autolink syntax allows
HTTP(S) links to be recognized in normal text without being delimited by
`<>`. This is the most natural way to write links in text, so it makes
sense to support it and allow documentation comments to be written in a
more natural way.
Closes#19265
This commit implements support for Markdown autolinks delimited by angle
brackets. The precise syntax accepted is documented in the doc comment
of `markdown.zig`.
Some users are hitting this limit. I think it's primarily due to not
deduplicating (solved in the previous commit) but this seems like a
better limit regardless.
