There is no way to know the expected parent pointer attributes (most
notably alignment) from the type of the field pointer, so provide them
in the first argument.
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.
Closes#19403
This commit adds all modules in the compilation to the generated
`sources.tar` when using `-femit-docs` (including `std` and `builtin`).
Additionally, it considers the main module when doing so, rather than
the root module, so the behavior when running `zig test -femit-docs
test.zig` is now correct.
Notably, this improves string printing from
`@as(*[5:0]u8, &@as([5:0]u8, "hello".*))` to `@as(*[5:0]u8, "hello")`,
omitting the pointless ref-deref pair.
