| void diagnostics::maybe_unwind_expanded_macro_loc | ( | text_sink & | text_output, |
| location_t | where ) |
Unwind the different macro expansions that lead to the token which
location is WHERE and emit diagnostics showing the resulting
unwound macro expansion trace. Let's look at an example to see how
the trace looks like. Suppose we have this piece of code,
artificially annotated with the line numbers to increase
legibility:
$ 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 }
Here is the diagnostic that we want the compiler to generate:
test.c: In function ‘g’:
test.c:5:14: error: invalid operands to binary << (have ‘double’ and ‘int’)
test.c:2:9: note: in definition of macro 'OPERATE'
test.c:8:3: note: in expansion of macro 'SHIFTL'
test.c:13:3: note: in expansion of macro 'MULT'
The part that goes from the third to the fifth line of this
diagnostic (the lines containing the 'note:' string) is called the
unwound macro expansion trace. That's the part generated by this
function.

This is a diagnostic finalizer implementation that is aware of virtual locations produced by libcpp. It has to be called by the diagnostic finalizer of front ends that uses libcpp and wish to get diagnostics involving tokens resulting from macro expansion. For a given location, if said location belongs to a token resulting from a macro expansion, this starter prints the context of the token. E.g, for multiply nested macro expansion, it unwinds the nested macro expansions and prints them in a manner that is similar to what is done for function call stacks, or template instantiation contexts.
