2012-10-10 Thread Xian, Yuqiang
Hi, As you may already know there's a new x32 ABI - a 32-bit psABI for x86-64 with 32-bit pointer size. It tries to leverage the advantage of more registers and IP relative addressing from x64 and the advantage of smaller memory footprint from IA32. You can find more details of the x32 ABI

My guess is that frequency of hits on given cache items approximately follows a power law distribution, and therefore increasing cache size gives diminishing returns. FWIW, a few years back I did some in-depth data gathering on this score using real world websites. I found that, for encoded

Hi, I don't think another branch on webkit.org will help you much; then you can as well have a branch anywhere. If you want this code to be well tested and maintained, you need to get it upstream (through all the review process) and promise that you have resources to keep maintaining it. It will
