Fix IEEE 754 NaN comparisons in constant folding (#7721)

2025-07-11T17:12:17+00:00

* Fix IEEE 754 NaN comparisons in constant folding Added proper NaN handling in SCCP optimization pass to follow IEEE 754 standard: - NaN \!= any value returns true - All other NaN comparisons return false - Added double precision NaN detection support - Fixed type detection to check operands instead of result type * Avoid differentiating NaN and non-NaN cases * format code (#76) --------- Co-authored-by: slangbot

Fix the sign-extending issue in right shift (#3820)

2024-03-26T18:05:00+00:00

Fix issue (#3637). In constant folding of a right shift operation,slang always uses signed interger as the operand no matter the input source code is signed or unsigned, this could causes sign-extending issue if the input source is unsigned integer with highest bit set to 1. Fix the issue by checking the original type of the input and use the unsigned type if the input is unsigned.
