test.c:4: error: overflow in enumeration values
It would be difficult to make the front-end track also the column number where
it encountered (estimated) the error?
That's gcc, and 4 is the line number (and the wrong line number) of the error.
No column number.
This will make error messages a bit more clear (and in the line of thos in gcc),
especially for long code lines (where you could have, for example, several
instructions on the line).
At the beginning, until the feature is really implemented, the front-end could
always provide "column=1", ie stick with current approach.
But this will help the gdc/ldc-implementations to be in line with the messages
provided by gcc and clang.
Tracking the column number is certainly doable, but it comes at a cost of memory
consumption and some compile speed, since it has to be tracked in every token. I
used to do it in the Digital Mars C compiler, but it was of only marginal
utility and I dropped it.
