George Koehler b90c97b00b Teach top to merge or delete "addi sp, sp, X". ... This reduces code size, because ncg emits too many "addi sp, sp, X" instructions when unstacking things. Now top lowers "addi sp, sp, X" by lifting other instructions. This sometimes creates chances to merge or delete _addi_ instructions. If no such chance is found, the _addi_ remains uselessly lowered. Edit ncg/table to remove something that top now does. Edit ncg/mach.c to remove some spaces after commas. This removes a whitespace difference between *.s and *.so files, because top removes the space.		2018-01-05 17:55:50 -05:00
