pthier 733c76b95c Reland "[heap] Transition/Shortcut strings only during GCs without stack" ... This is a reland of commit 7bf94d0336 Changes since revert: - Update string forwarding table with evacuated objects in mark compact. - Always mark forward objects in string forwarding table. Original change's description: > [heap] Transition/Shortcut strings only during GCs without stack > > By limiting transitions of (shared) strings and shortcutting of > Thin/Cons strings to GC withouts stacks, optimizing compilers can rely on > the invariant that string maps do not change during a GC, allowing them > to eliminate map checks and enable more aggressive optimizations. > > Change-Id: Ic9c9ed7b04b2ceed369484bf048965c083a9a693 > Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/4030578 > Commit-Queue: Patrick Thier <pthier@chromium.org> > Reviewed-by: Dominik Inführ <dinfuehr@chromium.org> > Cr-Commit-Position: refs/heads/main@{#84347} Change-Id: I1ab0965ff421635457a66fbe7f178d951afe4402 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/4035240 Reviewed-by: Dominik Inführ <dinfuehr@chromium.org> Commit-Queue: Patrick Thier <pthier@chromium.org> Cr-Commit-Position: refs/heads/main@{#84424}		2022-11-22 16:37:57 +00:00
