[Bug target/21623] New: [4.0 regression] ICE in reload_cse_simplify_operands, at postreload.c:391

["dank at kegel dot com" <gcc-bugzilla at gcc dot gnu dot org>]

Using crosstool-0.34, building glibc-2.3.5 on sh4 is ok with gcc-3.4.3, 
fails with gcc-4.0.0.  The attached reduced testcase shows the error:

foo2.i: In function 'plural_eval':
foo2.i:78: error: insn does not satisfy its constraints:
(insn 190 188 275 24 (set (reg/v:SI 76 fr12 [orig:169 n ] [169])
        (reg:SI 147 t)) 129 {movsi_ie} (insn_list:REG_DEP_TRUE 188 (nil))
    (nil))
foo2.i:78: internal compiler error: in reload_cse_simplify_operands, at
