Emit macro expansion related diagnostics
In this third instalment the diagnostic machinery -- when faced with
the virtual location of a token resulting from macro expansion -- uses
the new linemap APIs to unwind the stack of macro expansions that led
to that token and emits a [hopefully] more useful message than what we
have today.
diagnostic_report_current_module has been slightly changed to use the
location given by client code instead of the global input_location
variable. This results in more precise diagnostic locations in
general but then the patch adjusts some C++ tests which output changed
as a result of this.
Three new regression tests have been added.
The mandatory screenshot goes like this:
[dodji@adjoa gcc]$ cat -n test.c
1 #define OPERATE(OPRD1, OPRT, OPRD2) \
2 OPRD1 OPRT OPRD2;
3
4 #define SHIFTL(A,B) \
5 OPERATE (A,<<,B)
6
7 #define MULT(A) \
8 SHIFTL (A,1)
9
10 void
11 g ()
12 {
13 MULT (1.0);/* 1.0 << 1; <-- so this is an error. */
14 }
[dodji@adjoa gcc]$ ./cc1 -quiet -ftrack-macro-expansion test.c
test.c: In function 'g':
test.c:5:14: erreur: invalid operands to binary << (have 'double' and 'int')
