Subject [Harmony Wiki] Update of "Jitrino OPT/hvn" by George Timoshenko
Date Tue, 06 May 2008 08:54:30 GMT
Dear Wiki user,

You have subscribed to a wiki page or wiki category on "Harmony Wiki" for change notification.

The following page has been changed by George Timoshenko:
http://wiki.apache.org/harmony/Jitrino_OPT/hvn

New page:
Hash value numbering pass eliminates common sub-expressions. This pass uses an in-order depth-first
traversal of the dominator tree instead of the more expensive iterative data flow analysis.
High-level value numbering effectively eliminates redundant address computation and check
instructions. For example, chkzero(), chknull(), and chkcast() HIR instructions are redundant
if guarded by explicit conditional branches.
