------- Comment #7 from pinskia at gcc dot gnu dot org 2006-11-14 09:46 -------
So the problem is that loop.c creates a tree for:
(plus:SI (reg:SI 3 bx)
(const:SI (unspec:SI [
(symbol_ref:SI ("dwarf_reg_size_table") [flags 0x2] <var_decl
0xb7ce10b0 dwarf_reg_size_table>)
] 1)))
From:
5106 expand_mult_add (rtx x, rtx target, rtx mult, rtx add, enum
machine_mode mode,
5107 int unsignedp)
(gdb) p debug_rtx(x)
(const_int 1 [0x1])
$6 = void
(gdb) p debug_rtx(mult)
(const_int 1 [0x1])
$7 = void
(gdb) p debug_rtx(add)
(plus:SI (reg:SI 3 bx)
(const:SI (unspec:SI [
(symbol_ref:SI ("dwarf_reg_size_table") [flags 0x2] <var_decl
0xb7ce10b0 dwarf_reg_size_table>)
] 1)))
