# FNAME : name of source file to generate - .h and .c files will be made
# N1 : block size (size of outer product matrix) (1..9)
# UNROLL1 : solver inner loop unrolling factor (1..)
# UNROLL2 : factorizer inner loop unrolling factor (1..)
# MADD : if nonzero, generate code for fused multiply-add (0,1)
# FETCH : how to fetch data in the inner loop:
# 0 - load in a batch (the `normal way')
# 1 - delay inner loop loads until just before they're needed
