2009-10-15 Michael Meissner <meissner@linux.vnet.ibm.com> Pat Haugen <pthaugen@us.ibm.com> Revital Eres <ERES@il.ibm.com> Peter Bergner <bergner@vnet.ibm.com> Backport rs6000 changes from GCC 4.5 mainline to 4.3 that fixes some problems that show up with vectorization. 2009-06-05 Michael Meissner <meissner@linux.vnet.ibm.com> PR tree-optimization/40219 * tree.c (iterative_hash_expr): Make sure the builtin function is a normal builtin function and not a front end or back end builtin before indexing into the built_in_decls array. PR tree-optimization/40049 * tree-vect-transform.c (vectorizable_operation): If the machine has only vector/vector shifts, convert the type of the constant to the appropriate type to avoid building incorrect trees, which eventually have problems with garbage collection. diff -rupN --exclude='*~' --exclude=autom4te.cache sles-11sp1-orig/gcc/tree.c sles-11sp1/gcc/tree.c --- sles-11sp1-orig/gcc/tree.c 2009-10-09 17:07:59.000000000 -0400 +++ sles-11sp1/gcc/tree.c 2009-10-13 13:02:08.000000000 -0400 @@ -5348,11 +5348,13 @@ iterative_hash_expr (const_tree t, hashv return val; } case FUNCTION_DECL: - /* When referring to a built-in FUNCTION_DECL, use the - __builtin__ form.
