But since searching characters are all ASCII, this method can be easily applied to 16bit characters too: Use NEON SIMD to load 16bit characters in interleaved manner (lowers and uppers), and checking uppers are zero and lowers are searching characters via table lookup. * Source/WTF/wtf/SIMDHelpers.h: (WTF::SIMD::findInterleaved): * Source/WebCore/html/parser/HTMLDocumentParserFastPath.cpp: (WebCore::HTMLFastPathParser::scanText): (WebCore::HTMLFastPathParser::scanAttributeValue): Canonical link: https://commits.webkit.org/280741@main To unsubscribe from these emails, change your notification settings at https://github.com/WebKit/WebKit/settings/notifications _______________________________________________ webkit-changes mailing list webkit-changes@lists.webkit.org https://lists.webkit.org/mailman/listinfo/webkit-changes
