In expr.h: /* For tree_fits_[su]hwi_p, tree_to_[su]hwi, fold_convert, size_binop, ssize_int, TREE_CODE, TYPE_SIZE, int_size_in_bytes, */ #include "tree-core.h"
However the functions tree_to_shwi(), tree_fits_shwi(), etc. are not declared in tree-core.h, but in tree.h This is not a problem because tree_to_shwi() gets called from within macros in expr.h, (eg: from ADD_PARM_SIZE and SUB_PARM_SIZE macros), and when these macros are called, tree.h has been already included in that translation unit before including expr.h (for example, in alias.c tree.h, is included before expr.h). I am replacing macros by static inline functions (http://gcc.gnu.org/ml/gcc/2013-12/msg00148.html), changing ADD_PARM_SIZE() from macro to function now gives an error, that tree_to_shwi() (and other things like ssizetype, etc.) are not defined in scope. Including tree.h removes these errors. Would it be better to include tree.h instead of tree-core.h (tree.h includes tree-core.h anyway), or shall I leave these macros untouched ?
