6 * Precompiled header for WebKit when built on Windows using

7 * GYP-generated project files. Not used by other build

8 * configurations.

9 *

10 * Using precompiled headers speeds the build up significantly. On a

11 * fast machine (HP Z600, 12 GB of RAM), an ~18% decrease in full

12 * build time was measured with only the stdlib headers added. More

13 * with the Blink specific headers.

24 // In Blink a lot of operations center around dom and Document, or around

25 // layout/rendering and LayoutObject. Those two headers are in turn pulling

26 // in large parts of Blink's other headers which means that every compilation

27 // unit is compiling large parts of Blink. By precompiling Document.h and

28 // LayoutObject.h we only have to compile those parts once rather than

29 // 1500 times. It can make a large difference in compilation times.

30 // config.h contains some base macros that headers can expect are present.
