Analyze the branching code at the end of MBB, returning true if it cannot be understood (e.g.
This function can analyze one/two way branching only and should (mostly) be called by target independent side.
it's a switch dispatch or isn't implemented for a target). Upon success, this returns false and returns with the following information in various cases:
Note that removeBranch and insertBranch must be implemented to support cases where this method returns success.
If AllowModify is true, then this routine is allowed to modify the basic block (e.g. delete instructions after the unconditional branch).
First entry is always the opcode of the branching instruction, except when the Cond vector is supposed to be empty, e.g., when analyzeBranch fails, a BB with only unconditional jump. Subsequent entries depend upon the opcode, e.g. Jump_c p will have Cond[0] = Jump_c Cond[1] = p HW-loop ENDLOOP: Cond[0] = ENDLOOP Cond[1] = MBB New value jump: Cond[0] = Hexagon::CMPEQri_f_Jumpnv_t_V4 – specific opcode Cond[1] = R Cond[2] = Imm
