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.
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.
Symmetry with parse_float and to hide the implementation from the user.
Additionally, we expose the entire namespace and provide some aliases so
everything is available to a user.
Closes#19366
