* Tests: Add a test to reproduce #3509 * Tests: Compile without tautological-compare check because bit op tree optimization is disabled in the test. * Internals: Dedup code. No functional change is intended. * Fix #3509. "2'b10 == (2'b11 & {1'b0, val[0]})" and "2'b10 != (2'b11 & {1'b0, val[0]})" were wrongly optimized to "!val[0]" and "val[0]" respectively. Now properly optimize them to 1'b0 and 1'b1. * Commentary * Commentary: Update Changes |
