------- Comment #2 from pinskia at gcc dot gnu dot org 2006-03-31 19:11 -------
Confirmed, a litte more reduced testcase:
typedef unsigned long long U64;
typedef unsigned short U16;
typedef unsigned char U8;
U16 m_rh;
U8 m_gN_eQ;
void f()
{
U16 m_;
m_gN_eQ = ((m_rh) ? 0x1ULL
: (U64)(m_ != 0x3fff))
== 0xffffffffffULL;
}
