# Note: the source modifier is the parameter before the source itself. So,
# src0_modifiers is the parameter in the list before src0, src1_modifiers before
# src1.
# For the srcN_modifiers, the following values are relevant for these tests:
# -  0: op_sel=0 and op_sel_hi=0
# -  4: op_sel=1 and op_sel_hi=0
# -  8: op_sel=0 and op_sel_hi=1
# - 12: op_sel=1 and op_sel_hi=1
# For every test where we test two register arguments, the size of the arguments
# and the used parts are encoded in the test name. Examples:
# - *_32_lo_lo_32_lo_lo: two args of size 32 where only the low parts are used
# - *_16_lo_hi_16_hi_hi: two args of size 16 where both parts of the first arg
#                        and the high part of the second arg are used
# For a "(lo|hi)_(lo|hi)" pair, the first field denotes the part controlled by
# op_sel, the second field the one controlled by op_sel_hi.
#
# For the mad_mix_* tests, op_sel and op_sel_hi have slightly different semantics:
# - op_sel_hi: selects if the full 32bit of the arg should be used or only a
#              16bit part (which is then selected by op_sel)
#     op_sel_hi=0 selects 32bit
#     op_sel_hi=1 selects 16bit
# - op_sel: selects low/high part of arg
# So, for the srcN_modifiers, we have the following values:
# -  0: op_sel=0 and 32bit (op_sel_hi=0)
# -  4: op_sel=1 and 32bit (op_sel_hi=0)
# -  8: op_sel=0 and 16bit (op_sel_hi=1)
# - 12: op_sel=1 and 16bit (op_sel_hi=1)
