basic-block.h (BLOCK_HEAD, BLOCK_END): Remove.
2003-12-11 Steven Bosscher <steven@gcc.gnu.org>
* basic-block.h (BLOCK_HEAD, BLOCK_END): Remove.
(BLOCK_HEAD_TREE, BLOCK_END_TREE): Remove.
(basic_block_def): Rename `head' to `head_' and `end' to `end_'.
(BB_HEAD, BB_END): New accessor macros for the `head_' and `end_'
fields of a basic block.
* bb-reorder.c, bt-load.c, caller-save.c, cfg.c, cfganal.c,
cfgbuild.c, cfgcleanup.c, cfglayout.c, cfgloop.c, cfgloopanal.c,

accessing the `head' and `end' fields of a basic block directly.
* gengtype.c: Add missing piece from earlier patch. Dunno what

|
|
|
(2) Any read outside an operand causes any chain it overlaps
|
|
|
|
|
|
with to be closed, since we can't replace it.
|
|
|
|
|
|
(3) Any read inside an operand is added if there's already
|
|
|
|
|
|
an open chain for it.
|
|
|
|
|
|
(4) For any REG_DEAD note we find, close open chains that
|
|
|
|
|
|
overlap it.
|
|
|
|
|
|
(5) For any write we find, close open chains that overlap it.
|
|
|
|
|
|
(6) For any write we find in an operand, make a new chain.
|
|
|
|
|
|
(7) For any REG_UNUSED, close any chains we just opened. */
