/*	Extract the inline cache tag for the object in sourceReg into destReg. The

	to distinguish
	objects of different classes. In Spur this is either the tags for
	immediates, (with
	1 & 3 collapsed to 1 for SmallIntegers, and 2 collapsed to 0 for
	Characters), or
	the receiver's classIndex.
	If forEntry is true answer the entry label at which control is to enter
	(cmEntryOffset). If forEntry is false, control enters at the start.
	If forEntry is true, generate something like this:
	Limm:
	andl $0x1, rDest
	j Lcmp
	Lentry:
	movl rSource, rDest
	andl $0x3, rDest
	jnz Limm
	movl 0(%edx), rDest
	andl $0x3fffff, rDest
	Lcmp:
	If forEntry is false, generate something like the following.
	At least on a 2.2GHz Intel Core i7 the following is slightly faster than
	the above,
	136m sends/sec vs 130m sends/sec for nfib in tinyBenchmarks
	Lentry:
	movl rSource, rDest
	andl $0x3, rDest
	jz LnotImm
	andl $1, rDest
	j Lcmp
	LnotImm:
	movl 0(%edx), rDest
	andl $0x3fffff, rDest
	Lcmp:
	But we expect most SmallInteger arithmetic to be performed in-line and so
	prefer the
	version that is faster for non-immediates (because it branches for
	immediates only). */

/*	replaceFrom: start to: stop with: replacement startingAt: repStart. 
	
	The primitive in the JIT tries to deal with two pathological cases, copy
	of arrays and byteStrings,
	which often copies only a dozen of fields and where switching to the C
	runtime cost a lot.
	
	Based on heuristics on the method class, I generate a quick array path
	(typically for Array),
	a quick byteString path (typically for ByteString, ByteArray and
	LargeInteger) or no quick 
	path at all (Typically for Bitmap).
	
	The many tests to ensure that the primitive won't fail are not super
	optimised (multiple reloading
	or stack arguments in registers) but this is still good enough and worth
	it since we're avoiding 
	the Smalltalk to C stack switch. The tight copying loops are optimised. 
	
	It is possible to build a bigger version with the 2 different paths but I
	(Clement) believe this 
	is too big machine code wise to be worth it.

/*	replaceFrom: start to: stop with: replacement startingAt: repStart. 
	
	The primitive in the JIT tries to deal with two pathological cases, copy
	of arrays and byteStrings,
	which often copies only a dozen of fields and where switching to the C
	runtime cost a lot.
	
	Based on heuristics on the method class, I generate a quick array path
	(typically for Array),
	a quick byteString path (typically for ByteString, ByteArray and
	LargeInteger) or no quick 
	path at all (Typically for Bitmap).
	
	The many tests to ensure that the primitive won't fail are not super
	optimised (multiple reloading
	or stack arguments in registers) but this is still good enough and worth
	it since we're avoiding 
	the Smalltalk to C stack switch. The tight copying loops are optimised. 
	
	It is possible to build a bigger version with the 2 different paths but I
	(Clement) believe this 
	is too big machine code wise to be worth it.
