At least by einline (after SSA and CFG have been built) we have: (gdb) p debug(gs) c_92 = __builtin_copysignf128 (0.0, c_80(D)); c_92 has a type of TFtype: (gdb) p debug_tree(lhs) <ssa_name 0x7fffef2d23b8 type <real_type 0x7fffef5211b8 TFtype sizes-gimplified TF size <integer_cst 0x7fffef221038 constant 128> unit-size <integer_cst 0x7fffef221050 constant 16> align:128 warn_if_not_align:0 symtab:0 alias-set -1 canonical-type 0x7fffef251500 precision:127 context <translation_unit_decl 0x7fffef510960 a.i>> visited var <parm_decl 0x7ffff7f84f80 c> def_stmt 163c_92 = __builtin_copysignf128 (0.0, c_80(D)); version:92> $12 = void Whereas 0.0 has a type of _Float128: (gdb) p gimple_call_arg (gs, 0) $13 = (tree_node *) 0x7fffef54d1a0 (gdb) p debug($13) 0.0 $14 = void (gdb) p debug_tree($13) <real_cst 0x7fffef54d1a0 type <real_type 0x7fffef2516f8 _Float128 TF size <integer_cst 0x7fffef221038 constant 128> unit-size <integer_cst 0x7fffef221050 constant 16> align:128 warn_if_not_align:0 symtab:0 alias-set -1 canonical-type 0x7fffef2516f8 precision:128> constant 0.0>
