[Cocci] Code wrapped in macros ignored by script

[Timur Tabi]

My cocci script (attached) ignores lines that are embedded inside other
macros.  Example:

#define DB(x)   x

void func()
{
    DB(if (DEBUG_IO_TRACE())
                DBG_PRINTF((DBG_MODULE_GLOBAL, DBG_LEVEL_INFO, "inb
%#04x \n", addr));)
}

Is there a way to get coccinelle to ignore the DB( and )?

No. Either Coccinelle can parse the macro use as is, which is not
possible here, because an if can't be an argument to a function call, or
it expands the macro, in which case no transformation is possible.
