https://bugs.webkit.org/show_bug.cgi?id=307692
Reviewed by Antti Koivisto.
Streamline the parser for the CSS display property by dispatching
from a single switch and using a compile time generated mapping of
<display-outside> + <display-inside> pairs to CSSValueIDs.
* Source/WTF/wtf/EnumeratedArray.h:
- Make remaining functions constexpr.
* Source/WebCore/css/parser/CSSPropertyParserConsumer+Display.cpp:
(WebCore::CSSPropertyParserHelpers::makeDisplayOutsideInsideMap):
- Generate a compile time mapping of <display-outside> + <display-inside>
pairs to CSSValueIDs, using EnumeratedArray as the backing to allow a
nice syntax for lookup.
(WebCore::CSSPropertyParserHelpers::consumeAfterInitialDisplayOutside):
(WebCore::CSSPropertyParserHelpers::consumeAfterInitialDisplayInside):
(WebCore::CSSPropertyParserHelpers::consumeDisplay):
- Implement the initial dispatch using a single switch on all possible
initial keywords and two generic helpers for the <display-outside> then
<display-inside> case and the <display-inside> then <display-inside> case.
