Subject: [Bug target/19496] New: [4.0 Regression] ICE in gcc.c-torture/execute/ieee/fp-cmp-8.c for x86_64 and i686 with -msse2 -mfpmath=sse

Hello!

gcc -msse2 -O1 -mfpmath=sse -da fp-cmp-8f.c 
In file included from fp-cmp-8f.c:2:
fp-cmp-8.c: In function âtest_islessgreaterâ:
fp-cmp-8.c:71: internal compiler error: in ix86_expand_fp_movcc, at
config/i386/i386.c:9813

The problem is that ltgt is not a valid sse_comparison_operator and gcc_assert()
is triggered in i386.c:

(jump_insn 13 12 18 0 (set (pc)
        (if_then_else (ltgt (reg:CCFPU 17 flags)
                (const_int 0 [0x0]))
            (label_ref 20)
            (pc))) 338 {*jcc_1} (nil)
    (expr_list:REG_BR_PROB (const_int 6700 [0x1a2c])
        (nil)))

Uros.
