From 554fd8c5195424bdbcabf5de30fdc183aba391bd Mon Sep 17 00:00:00 2001 From: upstream source tree Date: Sun, 15 Mar 2015 20:14:05 -0400 Subject: obtained gcc-4.6.4.tar.bz2 from upstream website; verified gcc-4.6.4.tar.bz2.sig; imported gcc-4.6.4 source tree from verified upstream tarball. downloading a git-generated archive based on the 'upstream' tag should provide you with a source tree that is binary identical to the one extracted from the above tarball. if you have obtained the source via the command 'git clone', however, do note that line-endings of files in your working directory might differ from line-endings of the respective files in the upstream repository. --- gcc/ChangeLog.graphite | 9074 ++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 9074 insertions(+) create mode 100644 gcc/ChangeLog.graphite (limited to 'gcc/ChangeLog.graphite') diff --git a/gcc/ChangeLog.graphite b/gcc/ChangeLog.graphite new file mode 100644 index 000000000..c3fd0094f --- /dev/null +++ b/gcc/ChangeLog.graphite @@ -0,0 +1,9074 @@ +2011-01-20 Sebastian Pop + + * graphite-sese-to-poly.c (dr_indices_valid_in_loop): New. + (close_phi_written_to_memory): Call for_each_index with + dr_indices_valid_in_loop. + + * gfortran.dg/graphite/id-24.f: New. + * gfortran.dg/graphite/id-25.f: New. + +2011-01-19 Sebastian Pop + + * graphite-sese-to-poly.c (new_pbb_from_pbb): Only copy PBB_DOMAIN + when it is initialized. + + * gfortran.dg/graphite/id-23.f: New. + +2011-01-19 Sebastian Pop + + * graphite-scop-detection.c (stmt_has_simple_data_refs_p): Update + call to graphite_find_data_references_in_stmt. + * graphite-sese-to-poly.c (outermost_loop_in_sese_1): New. + (try_generate_gimple_bb): Call outermost_loop_in_sese_1.
