BTW, is there a way yet in Coccinelle to match a fully qualified (?)
identifier? For example, if I have two lines in C:
A)
array_size(variable, 5);
B)
array_size(instance->member.size, 5);
C)
array_size(instance->member.size + 1, 5);
D)
array_size(function_call(variable), 5);
This matches A, B, C, and D:
@@
expression ARG1;
expression ARG2;
@@
array_size(ARG1, ARG2);
This matches only A:
@@
identifier ARG1;
expression ARG2;
@@
array_size(ARG1, ARG2);
How do I get something to match A and B but not C and D (i.e. I do not
want to match any operations, function calls, etc, only a variable,
which may be identified through dereference, array index, or struct
member access.)
