From b12ebd96ba91490e361a139dca9d0fc17a67312f Mon Sep 17 00:00:00 2001 From: Andrew MacLeod Date: Thu, 12 Sep 2013 13:30:31 +0000 Subject: tree-flow.h (FREE_SSANAMES): Move to tree-ssanames.c (SSANAMES... * tree-flow.h (FREE_SSANAMES): Move to tree-ssanames.c (SSANAMES, MODIFIED_NORETURN_CALLS, DEFAULT_DEFS, ptr_info_def, num_ssa_names, ssa_name): Move to tree-ssanames.h + prototypes. * tree-flow-inline.h (make_ssa_name, copy_ssa_name, duplicate_ssa_name, make_temp_ssa_name): move to tree-ssanames.h * tree-ssa-alias.h: Move prototype. * tree-ssa.h: Include tree-ssanames.h. * tree-ssanames.c (FREE_SSANAMES): Move to here. * tree-ssanames.h: New. Move items from tree-flow*.h * Makefile.in (tree-ssanames.h): Add to tree-ssanames.o and GTFILES.
