35 the logic unchanged otherwise except for using bdst as the destination
36 register of the compare_and_swap insn.

38 returned to the function comment. Rename scratch variable to
39 neg_bval. Adapt initialization of variables holding operands to the
40 new operand numbers. Use return register to hold result of store
41 exclusive for Thumb-1, scratch register otherwise. Construct the
42 appropriate cbranch for Thumb-1 targets, keeping the logic unchanged
43 for 32-bit targets. Guard Z flag setting to restrict to 32bit targets.
