invoke.texi (graphite-max-bbs-per-function): Remove.
2017-09-27 Richard Biener <rguenther@suse.de>
* doc/invoke.texi (graphite-max-bbs-per-function): Remove.
(graphite-max-nb-scop-params): Document special value zero.
* domwalk.h (dom_walker::STOP): New symbolical constant.
(dom_walker::dom_walker): Add optional parameter for bb to
RPO mapping.
(dom_walker::~dom_walker): Declare.
(dom_walker::before_dom_children): Document STOP return value.
(dom_walker::m_user_bb_to_rpo): New member.
(dom_walker::m_bb_to_rpo): Likewise.
* domwalk.c (dom_walker::dom_walker): Compute bb to RPO
mapping here if not provided by the user.
(dom_walker::~dom_walker): Free bb to RPO mapping if not
provided by the user.
(dom_walker::STOP): Define.
(dom_walker::walk): Do not compute bb to RPO mapping here.
Support STOP return value from before_dom_children to stop
walking.
* graphite-optimize-isl.c (optimize_isl): If the schedule
is the same still generate code if -fgraphite-identity
or -floop-parallelize-all are given.
* graphite-scop-detection.c: Include cfganal.h.
(gather_bbs::gather_bbs): Get and pass through bb to RPO
mapping.
(gather_bbs::before_dom_children): Return STOP for BBs
not in the region.
(build_scops): Compute bb to RPO mapping and pass it to
the domwalk. Treat --param graphite-max-nb-scop-params=0
as not limiting the number of params.
* graphite.c (graphite_initialize): Remove limit on the
number of basic-blocks in a function.
* params.def (PARAM_GRAPHITE_MAX_BBS_PER_FUNCTION): Remove.
(PARAM_GRAPHITE_MAX_NB_SCOP_PARAMS): Adjust to documented
default value of 10.
