This patch is causing a crash in our builds. here is a repro:

  clang -cc1 -triple aarch64-cros-linux-gnu -emit-obj -ffp-contract=fast -ffast-math -O2 -x c crash.txt
  
  double a();
  int b(char *d) {
    _Bool e;
    double exponent;
    char *c = d;
    e = 1;
    do
      exponent = 10.0 * exponent - '0';
    while (c);
    a((e ? -1.0 : 1.0) * exponent);
  }
