https://bugs.webkit.org/show_bug.cgi?id=110179 Reviewed by Oliver Hunt. Share the SourceProvider's string instead of making our own copy. This chops off 16MB - 32MB from the CodeCache's memory footprint when full. (It's 16MB when the strings are LChar, and 32MB when they're UChar.) * runtime/CodeCache.cpp: (JSC::CodeCache::getFunctionExecutableFromGlobalCode): * runtime/CodeCache.h: Removed a defunct enum value. (JSC::SourceCodeKey::SourceCodeKey): (JSC::SourceCodeKey::isHashTableDeletedValue): (SourceCodeKey): (JSC::SourceCodeKey::hash): (JSC::SourceCodeKey::length): (JSC::SourceCodeKey::isNull): (JSC::SourceCodeKey::string): (JSC::SourceCodeKey::operator==): Store a SourceCode instead of a String so we can share our string with our SourceProvider. Cache our hash so we don't have to re-decode our string just to re-hash the table. git-svn-id: http://svn.webkit.org/repository/webkit/trunk@143348 268f45cc-cd09-0410-ab3c-d52691b4dbfc
