is_branch_taken | mpute branch direction of the expression "if (reg opcode val) goto target;"* and return:* 1 - branch will be taken and "goto target" will be executed* 0 - branch will not be taken and fall-through to next insn* -1 - unknown |
reg_set_min_max | Adjusts the register min/max values in the case that the dst_reg is the* variable register that we are working on, and src_reg is a constant or we're* simply doing a BPF_K check.* In JEQ/JNE cases we also adjust the var_off values. |
reg_set_min_max_inv | Same as above, but for the case that dst_reg holds a constant and src_reg is* the variable reg. |
