Pull request overview
Fixes Arm64 SVE mask-related test failures by treating float/double “mask lanes” as bit-patterns rather than numeric values, ensuring correct handling when masks are produced via reinterpret/bitcast semantics.
Changes:
- Default “all-true” masks for
double[]/float[]now use a non-zero bit-pattern viaBitConverter.*BitsTo*. - Mask checks in
AddSequentialAcrossnow evaluate mask lanes by checking their raw bits for non-zero. MaskBothSetnow checks for raw bit-pattern equality (== 1) instead of numeric equality (== 1.0).
