Wilson Snyder	7c6c6a684b	Add SPDX copyright identifiers, and get 'reuse' clean. No functional change.	2026-01-26 20:24:34 -05:00
Geza Lore	af1be26b96	Fix O(n*2) analysis in const-bit-op-tree (#6791 ) Note this might miss some cases where a sub-tree within an And/Or/Xor tree is optimizeable, but not the whole tree, but in practice this seems to work better than the alternative of keeping a set of failed nodes and bail early.	2025-12-11 14:32:25 +00:00
Geza Lore	d9701e6406	Automatically split some packed variables (#5843 ) This patch adds a heuristic to V3SplitVar, and it attempts to split up packed variables that are only referenced via constant index, non-overlapping bit/range selects. This can eliminate some UNOPTFLAT cases.	2025-03-09 10:31:01 -04:00
Wilson Snyder	2c52119d6c	Tests: Rename some tests into proper groups. No functional change.	2024-09-21 10:04:58 -04:00
