72347 2011-11-14 20:14:04 -0800 DFG should support deep OSR 2011-11-15 16:56:19 -0800 1 1 1 Unclassified WebKit JavaScriptCore 528+ (Nightly build) All All RESOLVED WONTFIX P2 Normal --- 72348 1 fpizlo webkit-unassigned oldest_to_newest 502599 0 fpizlo 2011-11-14 20:14:04 -0800 The runtime may realize that any further execution of a code block optimized by the DFG is impossible. We can make this work by jettisoning the code block and performing OSR even though the code block could be in use by any number of stack frames beneath the current one. 503451 1 fpizlo 2011-11-15 16:56:15 -0800 I originally posted this because I thought it would block https://bugs.webkit.org/show_bug.cgi?id=72312. But I've decided that the best way to do this is to avoid deep OSR altogether. Closing unless we find another reason why we need to do this.
