◆ analyzeBranch()
|
override |
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:
- If this block ends with no branches (it just falls through to its succ) just return false, leaving TBB/FBB null.
- If this block ends with only an unconditional branch, it sets TBB to be the destination block.
- If this block ends with a conditional branch and it falls through to a successor block, it sets TBB to be the branch destination block and a list of operands that evaluate the condition. These operands can be passed to other TargetInstrInfo methods to create new branches.
- If this block ends with a conditional branch followed by an unconditional branch, it returns the 'true' destination in TBB, the 'false' destination in FBB, and a list of operands that evaluate the condition. These operands can be passed to other TargetInstrInfo methods to create new branches.
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

◆ insertBranch()

override |
Insert branch code into the end of the specified MachineBasicBlock.
The operands to this method are the same as those returned by analyzeBranch. This is only invoked in cases where analyzeBranch returns success. It returns the number of instructions inserted.
It is also invoked by tail merging to add unconditional branches in cases where analyzeBranch doesn't apply because there was no original branch to analyze. At least this much must be implemented, else tail merging needs to be disabled.

◆ removeBranch()
|
override |
Remove the branching code at the end of the specific MBB.
This is only invoked in cases where analyzeBranch returns success. It returns the number of instructions that were removed.

override |
Reverses the branch condition of the specified condition list, returning false on success and true if it cannot be reversed.

◆ storeRegToStackSlot()
|
override |
Store the specified register of the given register class to the specified stack frame index.
The store instruction is to be added to the given machine basic block before the specified machine instruction. If isKill is true, the register operand is the last use and must be marked kill.
