The relocation constant name is determined as follows :
73
R_16C_<format><size>[_C]
77
<format> is one of the following:
78
NUM - R_NUMBER mnemonic,
79
DISP - R_16C_DISPL mnemonic,
80
REG - R_16C_REGREL mnemonic,
81
ABS - R_16C_ABS mnemonic,
82
IMM - R_16C_IMMED mnemonic,
83
<size> stands for R_S_16C_<size>
84
_C means 'code label' and is only added when R_ADDRTYPE subfield
85
is of type R_CODE_ADDR. */
