/* How do we represent a source location? I mean, how should we
represent them within GDB; the user wants to use all sorts of
ambiguous abbreviations, like "break 32" and "break foo.c:32"
number." This is analogous to the way GCC reports errors in
#include files:
- $ gcc -c base.c
- In file included from header2.h:8,
- from header1.h:3,
- from base.c:5:
- header3.h:1: parse error before ')' token
- $
+ $ gcc -c base.c
+ In file included from header2.h:8,
+ from header1.h:3,
+ from base.c:5:
+ header3.h:1: parse error before ')' token
+ $
GCC tells you exactly what path of #inclusions led you to the
problem. It gives you complete information, in a way that the
following would not:
- $ gcc -c base.c
- header3.h:1: parse error before ')' token
- $
+ $ gcc -c base.c
+ header3.h:1: parse error before ')' token
+ $
Converting all of GDB to use this is a big task, and I'm not really
suggesting it should be a priority. But this module's whole
line info, but not in macro info. This means that GDB's symtabs
(built from the former, among other things) may mention filenames
that the #inclusion tree (built from the latter) doesn't have any
- record of. See macroscope.c:sal_macro_scope for how to accomodate
+ record of. See macroscope.c:sal_macro_scope for how to accommodate
this.
It's worth noting that libcpp has a simpler way of representing all
the same source location (although 'gcc -DFOO -UFOO -DFOO=2' does
do that in GCC 4.1.2.). */
