According to the calling convention, the registers q4-q7 should be preserved by functions. The caller (generated by the compiler) could be using those registers anywhere for any intermediate data. Functions that use 12 or less of the qX registers can avoid violating the calling convention by simply using other registers instead of the callee saved registers q4-q7. This change only remaps the registers used within functions - therefore this does not affect performance at all. E.g. in functions using registers q0-q7, we now use q0-q3 and q8-q11 instead. |
