[LLVMdev] Loop unrolling opportunity in SPEC's libquantum with profile info
...ach basis state */

The code is writing to the 'state' field. The data structures look like this:
typedef struct quantum_matrix_struct quantum_matrix;
struct quantum_reg_node_struct
{
COMPLEX_FLOAT amplitude; /* alpha_j */
MAX_UNSIGNED state; /* j */
};
typedef struct quantum_reg_node_struct quantum_reg_node;
/* The quantum register */
struct quantum_reg_struct
{
int width; /* number of qubits in the qureg */
int size; /* number of non-zero vectors */
int hashw; /* width of the hash array...

Joint modelling of survival data
Assume that we collect below data : -
subjects = 20 males + 20 females, every single individual is independence,
and difference
events = 1, 2, 3... n
covariates = 4 blood types A, B, AB, O

?m = hazards rates for male
?n = hazards rates for female
Wm = Wn x ?, frailty for males, where ? is the edge ratio of male compare to
female
Wn =

No. The vectorizer stated that it wasn't going to bother with the loop
because it wasn't profitable. Specifically:
