From f06ecc4bbaf059ac29c480a7de77c5132eb23c17 Mon Sep 17 00:00:00 2001 From: Riyadh Baghdadi Date: Thu, 30 Sep 2010 21:17:33 +0000 Subject: [PATCH] Dump each scop in a separate file. 2010-08-17 Riyadh Baghdadi * graphite-poly.c (init_graphite_out_file): New. (init_graphite_in_file): New. (apply_poly_transforms): Updated to enable reading and writing of multiple scop files. * toplev.c (init_asm_output): Remove graphite in/out file initialization.
