https://bugs.webkit.org/show_bug.cgi?id=123107 Reviewed by Geoffrey Garen. * runtime/JSLock.cpp: (JSC::JSLock::unlock): (JSC::JSLock::dropAllLocks): Modified to take a SpinLock, used only on iOS. (JSC::JSLock::dropAllLocksUnconditionally): Modified to take a SpinLock, used only on iOS. Also use pre-increment instead of post-increment when we're not using the return value of the instruction. (JSC::JSLock::grabAllLocks): Modified to take a SpinLock, used only on iOS. Also change places where we were using post-increment/post-decrement to use pre-increment/pre-decrement, since we don't use the return value of such instructions. (JSC::JSLock::DropAllLocks::DropAllLocks): Modified to support releasing all locks unconditionally. Take a spin lock before releasing all locks on iOS. Also, use nullptr instead of 0. (JSC::JSLock::DropAllLocks::~DropAllLocks): Take a spin lock before acquiring all locks on iOS. * runtime/JSLock.h: Remove extraneous argument name "exec" from DropAllLocks as the data type of the argument is sufficiently descriptive of its purpose. git-svn-id: http://svn.webkit.org/repository/webkit/trunk@157809 268f45cc-cd09-0410-ab3c-d52691b4dbfc
