Might it be possible to alternatively add an attribute symbol hook so that a
target may easily define an arbitrary target specific named attribute which
may be utilized without having to patch the parser, etc. to do so?

Thereby one could easily define a ROM and/or PMEM attribute hypothetically
for not only __FUNCTION__, but any arbitrary declared type or parameter
declaration, preserved through to the back end to aid in target specific
code generation and/or memory allocation?

PMEM __FUNCTION__ 

ROM static const x[] = "some string"

char y[] = ROM "some string"

struct {int a; int b;} z = PMEM {5312, 3421};

For example? (with a little luck this could kill two bird with one stone)
