bc: only check for ^C in bc_program_exec() main loop
Checking it in individual operations such as SQRT is not necessary since they usually do not take very long to complete. We repeatedly return to main loop. TODO: re-add more fine-grained ^C checks - but only with examples where it is actually needed. E.g. I suspect simplest ops like addition or compare won't need it. function old new delta bc_program_index 66 64 -2 bc_num_s 258 246 -12 bc_num_cmp 294 275 -19 bc_num_compare 84 59 -25 bc_num_subArrays 74 47 -27 bc_num_a 474 445 -29 bc_program_exec 4530 4500 -30 bc_num_p 518 472 -46 bc_num_d 604 558 -46 bc_num_k 1005 957 -48 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 0/10 up/down: 0/-284) Total: -284 bytes text data bss dec hex filename 988601 485 7296 996382 f341e busybox_old 988317 485 7296 996098 f3302 busybox_unstripped Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com> |
