           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3

A recent powerpc64-linux build of gcc:

gcc version 4.7.0 20110630 (experimental) (GCC) 

gets an ICE with the following testcase (originally from a kernel compile):

static inline __attribute__((always_inline)) void zot(unsigned a, unsigned b)
{
    if (__builtin_constant_p(a > 4096 || b > 0))
        asm volatile("":::"memory");
}

int foo(unsigned long a)
{
    unsigned b = 4096 - a;
    zot(a + b, 0);

    return 1;
}

fs/buffer.i:13:1: internal compiler error: tree check: expected ssa_name, have
integer_cst in set_cond_stmt_execution_predicate, at ipa-inline-analysis.c:1188
