There are 49 steps from AST to final assembly code. all define in ssa source.
That is, 53 columns are shown in default.
If you want to generate SVG of those 49 steps, please use -f myfunc:x-y,z, in which x, y, z are ssa passes name.
for example, -f main:number_lines-early_copyelim,stackfram. ("_" will be replaced by space when parsed)
