Question

I tried to use astyle to format the code base I’ve to work with. When I use the option –add-brackets the executable is not identical (If I only use -t and/or -b the output is identical).

if(a) return b

is modified to

if(a)
{
     return b
}

So my question is. Does gcc generate the same output if I only add and/or delete braces (obviously only for one liners like above). I tried some simple test case but already got an bit identical executable.

Answer 1

1, No

2, Use the – s flag to see the assembler ( or Using GCC to produce readable assembly? to get more readable assembler)
