-// in V8 ABI. All 64 bits are preserved in V9 ABI for all registers.
-
-// g2-g4 are scratch registers called "application globals".  Their
-// meaning is reserved to the "compilation system"--which means us!
-// They are are not supposed to be touched by ordinary C code, although
-// highly-optimized C code might steal them for temps.  They are safe
-// across thread switches, and the ABI requires that they be safe
-// across function calls.
-//
-// g1 and g3 are touched by more modules.  V8 allows g1 to be clobbered
-// across func calls, and V8+ also allows g5 to be clobbered across
-// func calls.  Also, g1 and g5 can get touched while doing shared
-// library loading.
-//
-// We must not touch g7 (it is the thread-self register) and g6 is
-// reserved for certain tools.  g0, of course, is always zero.

-// The compiler requires that G5_megamorphic_method is G5_inline_cache_klass,
-// because a single patchable "set" instruction (NativeMovConstReg,
-// or NativeMovConstPatching for compiler1) instruction
-// serves to set up either quantity, depending on whether the compiled
-// call site is an inline cache or is megamorphic.  See the function
-// CompiledIC::set_to_megamorphic.
-//
-// If a inline cache targets an interpreted method, then the
-// G5 register will be used twice during the call.  First,
-// the call site will be patched to load a compiledICHolder
-// into G5. (This is an ordered pair of ic_klass, method.)
-// The c2i adapter will first check the ic_klass, then load
-// G5_method with the method part of the pair just before
-// jumping into the interpreter.
-//
-// Note that G5_method is only the method-self for the interpreter,
-// and is logically unrelated to G5_megamorphic_method.
-//
-// Invariants on G2_thread (the JavaThread pointer):
-//  - it should not be used for any other purpose anywhere
-//  - it must be re-initialized by StubRoutines::call_stub()
-//  - it must be preserved around every use of call_VM
-
-// We can consider using g2/g3/g4 to cache more values than the
-// JavaThread, such as the card-marking base or perhaps pointers into
-// Eden.  It's something of a waste to use them as scratch temporaries,
-// since they are not supposed to be volatile.  (Of course, if we find
-// that Java doesn't benefit from application globals, then we can just
-// use them as ordinary temporaries.)
-//
-// Since g1 and g5 (and/or g6) are the volatile (caller-save) registers,
-// it makes sense to use them routinely for procedure linkage,
-// whenever the On registers are not applicable.  Examples:  G5_method,
-// G5_inline_cache_klass, and a double handful of miscellaneous compiler
-// stubs.  This means that compiler stubs, etc., should be kept to a

-// pops back to that caller's stack frame, and executes that
-// caller's exception handler.  Obviously, this process will
-// iterate until the control stack is popped back to a method
-// containing an applicable catch block.  A key invariant is
-// that the Oissuing_pc value is always a value local to
-// the method whose exception handler is currently executing.
-//
-// Note:  The issuing PC value is __not__ a raw return address (I7 value).
-// It is a "return pc", the address __following__ the call.

+// call site is an inline cache or is megamorphic.  See the function
+// CompiledIC::set_to_megamorphic.
+//
+// If a inline cache targets an interpreted method, then the
+// G5 register will be used twice during the call.  First,
+// the call site will be patched to load a compiledICHolder
+// into G5. (This is an ordered pair of ic_klass, method.)
+// The c2i adapter will first check the ic_klass, then load
+// G5_method with the method part of the pair just before

+// Note that G5_method is only the method-self for the interpreter,
+// and is logically unrelated to G5_megamorphic_method.

+//  - it should not be used for any other purpose anywhere
+//  - it must be re-initialized by StubRoutines::call_stub()
+//  - it must be preserved around every use of call_VM
+
+// We can consider using g2/g3/g4 to cache more values than the
