downloadbusybox-c1dc5d947384a338d7630e035c42a76c43eeb340.tar.gz
reduced .bss size by dynmaically allocating a certain large
array instead of letting it be static. objdump -t busybox \ | grep .bss \ | sed 's/^.*\.bss //' \ | grep -v ABS \ #| perl -e 'while(<>) { @x = split; @y = reverse split(//, $x[0]); for ($i=0; $i<@y; $i++) { $s += $y[$i] * (16 ** $i); if ($y[$i] && $i > 2) { print "> $y[$i] * 16 ** $i $x[1]\n"; } } } print "$s\n";'
