8 rounds ChaCha20 provides a 2.5x speedup, and is still believed
to be safe.
Round-reduced versions are actually deployed (ex: Android filesystem
encryption), and thanks to the magic of comptime, it doesn't take much
to support them.
This also makes the ChaCha20 code more consistent with the Salsa20 code,
removing internal functions that were not part of the public API any more.
No breaking changes; the public API remains backwards compatible.
Bring this in line with how variable declarations are handled.
Open a new indentation level for the initialization expression to handle
nested expressions like blocks.
Closes#7618
The main realization here was that getting rid of the early returns
in renderWhile() and rewriting the logic into a mostly unified execution
path took things from ~200 lines to ~100 lines and improved consistency
by deduplicating code.
Also add several test cases and fix a few issues along the way:
Fixes https://github.com/ziglang/zig/issues/6114
Fixes https://github.com/ziglang/zig/issues/8022
Add failing testcase to reproduce issue 8088
Tidy up renderWhile(), factoring out renderWhilePayload()
Ensure correct newline is used before 'then' token in while/for/if
Handle indents for 'if' inside 'for' or 'while'
Stop special-casing 'if' compared to 'for' and 'while'
fix drivers: zig {cc,c++}
- `-dynamiclib` is an alias to `-shared`
- associate `-dynamiclib` with zig `.shared` semantics
fix drivers: zig {cc,c++,build-lib,build-exe}
- use `-dynamic` for {exe,dylib}
- for dylib this fixes a regression
- for exe this replaces incorrect use of `-static`
A warning is emitted when using the debug option --debug-log when the compiler
was not compiled using the build option -Dlog. Additionnaly, the scopes are not
added to log_scopes as they have no effect.
