From 5affe17f859a0857b9d9c7c638f1e4e3939d1172 Mon Sep 17 00:00:00 2001 From: Abderrazek Zaafrani Date: Tue, 27 Oct 2015 15:58:05 +0000 Subject: [PATCH] isl schedule tree Use isl_schedule_node instead of isl_band_list for isl-0.15. Passes regtest and bootstrap for isl-0.15 and isl-0.12.2 on x86_64-linux. gcc/ChangeLog: * graphite-optimize-isl.c (get_schedule_for_node_st): New callback function to schedule based on isl_schedule_node. (get_schedule_map_st): New schedule optimizer based on isl_schedule_node. (scop_get_domains): New. Return the isl_union_set containing the domains of all the pbbs. (optimize_isl): Call the new function get_schedule_map_st for isl-0.15 gcc/testsuite/ChangeLog: * gcc.dg/graphite/block-0.c: Changed to match pattern. * gcc.dg/graphite/interchange-1.c: Same. * gcc.dg/graphite/interchange-10.c: Same. * gcc.dg/graphite/interchange-11.c: Same. * gcc.dg/graphite/interchange-13.c: Same. * gcc.dg/graphite/interchange-3.c: Same. * gcc.dg/graphite/interchange-4.c: Same. * gcc.dg/graphite/interchange-7.c: Same. * gcc.dg/graphite/interchange-9.c: Same. * gcc.dg/graphite/uns-interchange-9.c: Same. * gfortran.dg/graphite/interchange-3.f90: Same.
