-// The target keeps two redundant pointer copies alive in the entry block --
-// spriteGroup1_ in r4 and spriteGroup2_ in r5 -- which agbcc otherwise deletes
-// in cse1, again in loop and again in combine. Two constructs keep them:
-// the r4 pin on spriteGroup1_, and the empty asm("") barriers below (they emit
-// no instructions and the "r" constraint accepts any register; they only stop
-// the alias pointers being coalesced with the pointers they duplicate, and stop
-// the OAM pointers being re-folded into base+displacement addressing).
-// spriteGroup2_ cannot also be pinned -- the target reuses r5 as a scratch
-// register once the alias dies, and a pin would reserve it for the whole
-// function. Three barriers is the floor; their exact placement is required for
-// a byte-identical match, so do not move or remove them.
