[Bug target/16624] New: [3.5.0 regression] [arm] segmentation fault on float accesses in the ?: operators' body


There is something wrong with the float access when the ?: operators are
used on arm. If the body of the ?: operators contain float variables the
compiler'll drop some errors.

I made several crosscompiler, and I only found that arm-*-linux 
doesn't handle the following c code:

float a;
void foo(float b) {
  a = (b > 0 ? 1  : (b < 0 ? -1 : 0));
}

Command line (arm-linux-gcc (GCC) 3.5.0 20040718):
arm-linux-gcc -c -O1 foo.i

Output:
foo.i: In function `foo':
foo.i:6: internal compiler error: in elim_reg_cond, at flow.c:3244
