Message:

Remove WTF::SpinLock
​https://bugs.webkit.org/show_bug.cgi?id=148208

Reviewed by Geoffrey Garen.

Source/JavaScriptCore:

Remove the one remaining use of SpinLock.

• API/JSValue.mm:

(handerForStructTag):

Source/WTF:

Remove the SpinLock.h file and remove references to the SpinLock class. Put the old SpinLock
algorithm in LockSpeedTest.cpp - which isn't compiled as part of a WTF or WebKit build - just
so we can still benchmark our locking algorithms against a spinlock baseline.

• WTF.vcxproj/WTF.vcxproj:
• WTF.xcodeproj/project.pbxproj:
• benchmarks/LockSpeedTest.cpp:
• wtf/CMakeLists.txt:
• wtf/Lock.h:
• wtf/SpinLock.h: Removed.
• wtf/WordLock.h:

File:

• trunk/Source/JavaScriptCore/API/JSValue.mm (modified) (2 diffs)
