Where to declare functions exported by fold-const.c (*_double)

[Kaveh R. Ghazi]

These functions:

add_double
neg_double
mul_double
lshift_double
rshift_double
lrotate_double
rrotate_double

are redundantly declared in both rtl.h and tree.h (and are defined in
fold-const.c.)

The functions are used in these files (with counts):

  34 ./fold-const.c:
   9 ./simplify-rtx.c:
   4 java/jcf-parse.c:
   3 ch/typeck.c:
   3 ./stmt.c:
   2 ch/lex.c:
   2 ch/decl.c:
   2 ch/convert.c:
   1 java/jcf-write.c:
   1 config/rs6000/rs6000.c:
   1 ch/expr.c:
   1 ./tree.c:
   1 ./explow.c:

My question is what's the best place to declare them: rtl.h, tree.h or
someplace else?  Neither rtl.h or tree.h seems to cover all the uses
right now.  So either way I'd have to add some includes.  I wanted
some input which way people prefer.
