            Bug ID: 250676
           Summary: Use memcpy in SVGPathByteStreamSource::readType
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2

          Assignee: webkit-unassigned at lists.webkit.org

Hi Team,

While going through Blink's commit, I came across following refactoring / optimization:

Blink Commit - https://chromium.googlesource.com/chromium/blink/+/f9411437595a5782eb1adba1f719d4448530bd93

WebKit Source - https://searchfox.org/wubkat/source/Source/WebCore/svg/SVGPathByteStreamSource.h#57

'''

This avoids having the compiler beating around the bush trying to
recognize the memcpy, and results in smaller code (roughly 50% smaller
measured for GCC 4.8). All at the affordable price of upsetting a few
language purists.

'''

Appreciate if someone can share input.

Thanks!
