When compiling attached file with "-march=iwmmxt -mtune=iwmmxt -O
-fno-omit-frame-pointer", then following error appears on line "score= sqr -
((diff*(int64_t)diff)>>(level+3))":

svq1enc.c: In function 'encode_block':
svq1enc.c:265: error: insn does not satisfy its constraints:
(insn 1636 1634 334 22 (set (reg:SI 43 wcgr0)
        (mem/c:SI (plus:SI (reg/f:SI 11 fp)
                (const_int -3888 [0xfffffffffffff0d0])) [0 D.8214+0 S4 A32]))
407 {*iwmmxt_movsi_insn} (nil)
    (nil))
svq1enc.c:265: internal compiler error: in reload_cse_simplify_operands, at
postreload.c:392

When compiling without -fno-omit-frame-pointer, everything works correctly.

Using built-in specs.
