preprocess: Global variables do not have newlines

[ChrisCummins]

>>> print(clgen.preprocess("""
constant const float c = 3.5f;
#define DTYPE float
#define ALPHA(a) c * a

inline DTYPE ax(DTYPE x) { return ALPHA(x); }

kernel void saxpy( /* SAXPY kernel */
    global DTYPE *input1,
    global DTYPE *input2,
    const int nelem)
{
    unsigned int idx = get_global_id(0);
    // = ax + y
    if (idx < nelem) {
        input2[idx] += ax(input1[idx]); }}
"""))

Expected output:

constant const float Ga = 3.5f;

inline float A(float a) {
  return Ga * a;
}

kernel void B(global float* a, global float* b, const int c) {
  unsigned int d = get_global_id(0);

  if (d < c) {
    b[d] += A(a[d]);
  }
}

Actual output:

constant const float Ga = 3.5f; inline float A(float a) {
  return Ga * a;
}

kernel void B(global float* a, global float* b, const int c) {
  unsigned int d = get_global_id(0);

  if (d < c) {
    b[d] += A(a[d]);
  }
}
