2125 * config/i386/i386.c (ix86_expand_builtin): [IX86_BUILTIN_PINSRW,
2126 IX86_BUILTIN_PINSRW128]: Fix wrong selector range in error message.
2127 * config/i386/i386.md (mmx_pinsrw, sse2_pinsrw): Fix selector
2129 (*mmx_pinsrw, *sse2_pinsrw): New patterns.
2130 * config/i386/i386/predicates.md (const_pow2_1_to_8_operand,
2131 const_pow2_1_to_128_operand): New predicates.

2135 * tree-mudflap.c (mf_varname_tree): decl_printable_name handles
2137 (mf_xform_derefs_1) [RESULT_DECL, STRING_CST]: Handle as innermost
2138 object. [ptr_type]: Remove unused variable.
2139 Remember nearest addressable array-element or record-component
2140 when checking bitfield components. Tolerate empty BIND_EXPR.

2144 * tree-vectorizer.c (vect_analyze_offset_expr): Strip conversions
2145 that don't narrow the value. Fail for other conversions.

2155 (cgraph_node_for_asm, cgraph_varpool_node_for_asm): New.
2156 (cgraph_varpool_node): Actually link up cgraph_varpool_nodes.
2157 * cgraph.h (struct cgraph_varpool_node): Add next.
2158 (cgraph_node_for_asm, cgraph_varpool_node_for_asm): Declare.
2159 * varasm.c (assemble_alias): Mark the target as needed.

2176 Olivier Hainque <hainque@act-europe.fr>
2178 * tree.c (int_fits_type_p): A narrower type always fits in a
2179 wider one, except for negative values into unsigned types.
2181 2005-01-01 Roger Sayle <roger@eyesopen.com>
2183 * tree.c (int_fits_type_p): Compare the result of force_fit_type
2184 with the original constant rather than require TREE_OVERFLOW.

2191 * tree-cfg.c (remove_useless_stmts_warn_notreached): Only warn if
2192 the source line is greater than 0.
2193 (remove_bb): Likewise.
