Replace BB_HEAD et al macros with functions
gcc/
2014-08-19 David Malcolm <dmalcolm@redhat.com>
* basic-block.h (BB_HEAD): Convert to a function. Strengthen the
return type from rtx to rtx_insn *.
(BB_END): Likewise.
(BB_HEADER): Likewise.
(BB_FOOTER): Likewise.
(SET_BB_HEAD): Convert to a function.
(SET_BB_END): Likewise.
(SET_BB_HEADER): Likewise.
(SET_BB_FOOTER): Likewise.
* cfgrtl.c (BB_HEAD): New function, from macro of same name.
Strengthen the return type from rtx to rtx_insn *. For now, this
is done by adding a checked cast, but this will eventually
become a field lookup.
(BB_END): Likewise.
(BB_HEADER): Likewise.
(BB_FOOTER): Likewise.
(SET_BB_HEAD): New function, from macro of same name. This is
intended for use as an lvalue, and so returns an rtx& to allow
in-place modification.
(SET_BB_END): Likewise.
(SET_BB_HEADER): Likewise.
(SET_BB_FOOTER): Likewise.
