These changes update the benchmark numbers and repeat counts in the
example files. The benchmark results have slightly varied, and these
updates reflect the most recent measurements.
This commit updates the benchmark results for various examples. The
benchmark times and repeat counts have been adjusted to reflect current
performance characteristics.
This commit updates the benchmark numbers in various example files. The
changes reflect recent performance optimizations or adjustments to the
benchmarking environment.
This commit updates the benchmark metadata in several example files. The
benchmark runs and repeat counts have been slightly adjusted due to
optimizations or minor variations in execution.
This commit introduces purity inference to the compiler's optimizer.
This allows for more aggressive constant folding and dead code
elimination by tracking which functions and global variables
are free of side effects.
Key changes include:
- Added `global_purity` field to `Optimizer` and `Environment`.
- Modified `Optimizer::is_pure` to recursively determine if an
AST node represents a pure computation.
- Introduced `Optimizer::try_fold_pure` to replace the old
`try_fold_intrinsic`, enabling folding of pure function calls
with constant arguments.
- Updated `Environment::register_native` and
`Environment::register_constant`
to optionally record purity.
- Added purity flags to several built-in functions in `core.rs` and
`datetime.rs`.
- A new example `optimizer_purity.myc` demonstrates the new feature.
