Does GCC tell us in any way (via the debug info) that a single source
line has more than a single statement?
If not, the only way for GDB to figure that out is to parse the source
code by itself.
No, it doesn't, but there is more information available from the
machine code than there is from the source code. For "for" statements,
it's conceivable to work out that there are multiple places in the
statement which serve as branch targets, via assembly analysis. Better
would be to record this in the debug info; there's no way to do it,
yet, but someone was bouncing around a proposal to record it in the
line table.
