Yukihiro "Matz" Matsumoto 4ab07c74d6 mruby-method: add comprehensive call-seq documentation for Method extensions
Added complete call-seq documentation for all Method extension methods in
mrblib/method.rb (3 methods):

## Method Extension Methods:

- to_proc: converts Method object to Proc for functional programming
  patterns, enables use with &: syntax for concise method references
  and supports full argument passing including blocks and keyword arguments

- << (left composition): method composition operator that calls other_proc
  first then this method, enables right-to-left function composition with
  mathematical notation f(g(x)) for building complex transformations

- >> (right composition): method composition operator that calls this method
  first then other_proc, enables left-to-right function composition with
  pipeline notation for intuitive data flow transformations

Yukihiro "Matz" Matsumoto 12d77d447b mruby-bigint: optimize division with single-limb divisor fast path
Implement comprehensive single-limb division optimization providing
significant performance improvements for the common case of dividing
by small numbers.

Technical implementation:
- Added mpz_div_limb() function with three optimization strategies:
  * Power-of-2 divisors: use bit shifts (q = x >> log₂(d), r = x & (d-1))
  * Single-limb to single-limb: direct hardware division
  * Multi-limb to single-limb: optimized digit-by-digit algorithm
- Integrated fast path in udiv() for yy->sz == 1 condition
- Manual bit-shift implementation to avoid function dependencies
- Proper edge case handling (zero dividend, division by zero)

Performance improvements:
- Single-limb division: 1,156K ops/sec (3.4x vs multi-limb)
- Multi->single-limb: 457K ops/sec (1.3x vs multi-limb)
- Power-of-2 division: 437K ops/sec (1.3x vs multi-limb)
- Mixed small divisions: 662K ops/sec (1.9x vs multi-limb)

Algorithm benefits:
Power-of-2 detection using (d & (d-1)) == 0 enables ultra-fast bit
operations. Multi-limb algorithm processes from MSB to LSB using
double-limb arithmetic to prevent overflow, avoiding expensive
normalization and trial division phases of general algorithm.

Applications:
Optimizes common operations like base conversion, modular arithmetic
with small moduli, and mathematical computations involving division
by constants. Particularly beneficial for embedded systems where
division by small integers is frequent.

Testing:
- All existing tests pass (1712/1712 successful)
- Comprehensive correctness verification for all optimization paths
- Performance benchmarks confirm expected speedup ratios
- Edge cases properly handled (zero, equal operands, out-of-range)

Yukihiro "Matz" Matsumoto e2c4e2f4a7 mruby-errno: add comprehensive call-seq documentation for errno handling
Added complete call-seq documentation for all errno module methods in
mrblib/errno.rb (3 methods):

## Errno Module Methods:

  dynamic errno constant detection by querying both system-defined errno
  values and superclass constants with proper boolean return values

- const_missing: handles dynamic errno constant definition when undefined
  constants are referenced, automatically defines errno classes for valid
  system error codes and delegates to superclass for invalid names

- constants: returns array of all available errno constant names on the
  system, includes both already defined constants and those that can be
  dynamically defined, with dependency note for mruby-metaprog gem

Yukihiro "Matz" Matsumoto b689f58651 mruby-bigint: optimize modular exponentiation with barrett reduction
Implement Barrett reduction optimization for modular exponentiation operations
to significantly improve performance for cryptographic and mathematical
computations. This optimization reuses the Barrett parameter throughout the
exponentiation algorithm instead of recalculating it for every modular
reduction.

Technical implementation:
- Optimized mpz_powm() and mpz_powm_i() functions for Barrett reduction
- Automatic optimization selection based on modulus size:
  * Small moduli (1 limb): existing single-limb optimization
  * Medium moduli (2-8 limbs): Barrett reduction with parameter reuse
  * Large moduli (>8 limbs): general division fallback
- Added temporary variable management for efficient memory usage
- Maintained backward compatibility with existing API

Performance improvements:
- 37% performance improvement for medium-sized moduli operations
- Benchmark results: 76K ops/sec (Barrett) vs 55K ops/sec (general)
- Optimal for cryptographic applications (RSA, DSA, ECC operations)
- Memory efficient with no persistent state between operations

Algorithm benefits:
Barrett reduction avoids expensive division operations by precomputing
a parameter μ and reusing it throughout the binary exponentiation process.
For a^b mod m operations, this provides significant speedup when the modulus
size is in the optimal range for Barrett reduction (64-512 bits).

Testing:
- All existing tests pass (1712/1712 successful)
- Comprehensive correctness verification with various input sizes
- Performance benchmarks confirm expected optimization behavior

Yukihiro "Matz" Matsumoto 6190234e3d mruby-bigint: integrate barrett reduction algorithm into modular arithmetic
Implement and integrate Barrett reduction algorithm to optimize modular
arithmetic operations for moderate-sized moduli (64-512 bits). This algorithm
provides significant performance improvements for cryptographic applications
and repeated modular operations.

Technical implementation:
- Added mpz_barrett_mu() to compute Barrett parameter μ = ⌊2^(2k)/m⌋
- Added mpz_barrett_reduce() with full 7-step Barrett algorithm
- Integrated into mpz_mod() with automatic selection criteria:
  * Single-limb modulus: existing fast path (unchanged)
  * Moderate moduli (2-8 limbs, dividend ≥ modulus + 2): Barrett reduction
  * Large moduli: general division fallback (unchanged)

Performance characteristics:
- Barrett reduction is most effective for 64-512 bit moduli
- Complements existing single-limb optimization for small moduli
- Transparent optimization with no API changes
- All existing tests pass (1712 tests successful)

Algorithm details:
Barrett reduction avoids expensive division by precomputing a parameter
and using only multiplications and bit shifts. The 7-step algorithm
approximates the quotient, performs modular reduction using power-of-2
operations, and applies final corrections to ensure 0 ≤ result < modulus.

Yukihiro "Matz" Matsumoto a39aabe2ac mruby-bigint: optimize modular arithmetic with single-limb fast path
Implement specialized modular reduction algorithm for single-limb modulus
to avoid expensive division operations. The optimization uses repeated
division with double-precision arithmetic for multi-limb dividends and
direct modulo operation for single-limb dividends.

Algorithm:
- Single-limb dividend: direct modulo operation (x % m)
- Multi-limb dividend: iterative reduction using double-precision arithmetic
  processing limbs from most significant to least significant

Purpose:
- Accelerate common modular arithmetic operations with small moduli
- Reduce computational overhead for cryptographic and mathematical operations
- Improve performance of rational number arithmetic that relies on modular ops

Performance impact:
- Single-limb modulus: ~1.04M ops/sec (6x improvement over general case)
- Maintains correctness for all existing modular arithmetic operations
- Zero impact on large modulus operations (fallback to existing algorithm)

for improved performance on large numbers:

- Implement binary GCD (Stein's algorithm) avoiding expensive division operations
- Use bit shifts and subtraction instead of modulo operations
- Handle special cases (zero values) efficiently
- Preserve common factors of 2 for correct results
- Maintain full compatibility with existing rational number functionality

Binary GCD is significantly faster for large numbers as it avoids the costly
division operations used in the Euclidean algorithm, using only bit operations,
addition, and subtraction.

implemented the behavior.

Yukihiro "Matz" Matsumoto ebc10f3c57 Add NODE_BEGIN for explicit begin...end blocks
This commit introduces NODE_BEGIN as a distinct AST node type for
explicit begin...end blocks, separate from NODE_STMTS which represents
general statement sequences. This distinction will be essential for
implementing CRuby-compatible begin...end while/until constructs.

Key changes:
- Added NODE_BEGIN enum in node.h
- Added new_begin() function in parse.y using optimized cons() structure
- Modified begin...end grammar rule to generate NODE_BEGIN nodes
- Added NODE_BEGIN codegen support in codegen.c
- Added NODE_BEGIN to parser dump functionality

NODE_BEGIN uses a simpler cons() structure instead of list2() for
better memory efficiency, as it only contains a single body node.
