JavaScriptCore:

Some string speedups. Makes sony.com cached 11% faster.

  • kjs/ustring.h: Made it possible for UChar objects to be uninitialized, which gives a speed boost. Inlined CString's +=, UString's destructor, +=, and +.
  • kjs/ustring.cpp: (UString::UString): Optimize const char * version, which showed up heavily in performance analysis. Added new two-UString version, which makes the + operator fast. (UString::ascii): Remove thread safety changes. Change static buffer to remember its size, and to always be at least 4096 bytes long; that way we never have to reallocate unless it's for a long string. Also make code to extract the characters significantly faster by getting rid of two pointer dereferences per character. (UString::is8Bit): Avoid one pointer dereference per character. (UString::toDouble): Use ascii() instead of cstring() to avoid copying the string.
  • kjs/collector.cpp: Remove unneeded APPLE_CHANGES.
  • kjs/regexp.cpp: Remove ifdefs around some APPLE_CHANGES that we want to keep, because they just fix warnings.
  • kjs/value.h: Remove obsolete APPLE_CHANGES comment.
  • JavaScriptCore.pbproj/project.pbxproj: Project Builder decided to move a line around in the file.

WebCore:

  • force-clean-timestamp: JavaScriptCore headers changed that require a full build here.
