Expand description

Function cursor.

A FuncCursor holds a mutable reference to a whole ir::Function while keeping a position too. The function can be re-borrowed by accessing the public cur.func member.

This cursor is for use before legalization. The inserted instructions are not given an encoding.

Fields

func: &'f mut Function

The referenced function.

Implementations

Create a new FuncCursor pointing nowhere.

Use the source location of inst for future instructions.

Create an instruction builder that inserts an instruction at the current position.

Trait Implementations

Get the current cursor position.

Set the current position.

Get the source location that should be assigned to new instructions.

Set the source location that should be assigned to new instructions.

Borrow a reference to the function layout that this cursor is navigating.

Borrow a mutable reference to the function layout that this cursor is navigating.

Exchange this cursor for one with a set source location. Read more

Rebuild this cursor positioned at pos.

Rebuild this cursor positioned at inst. Read more

Rebuild this cursor positioned at the first insertion point for block. This differs from at_first_inst in that it doesn’t assume that any instructions have been inserted into block yet. Read more

Rebuild this cursor positioned at the first instruction in block. Read more

Rebuild this cursor positioned at the last instruction in block. Read more

Rebuild this cursor positioned after inst. Read more

Rebuild this cursor positioned at the top of block. Read more

Rebuild this cursor positioned at the bottom of block. Read more

Get the block corresponding to the current position.

Get the instruction corresponding to the current position, if any.

Go to the position after a specific instruction, which must be inserted in the layout. New instructions will be inserted after inst. Read more

Go to a specific instruction which must be inserted in the layout. New instructions will be inserted before inst. Read more

Go to the position for inserting instructions at the beginning of block, which unlike goto_first_inst doesn’t assume that any instructions have been inserted into block yet. Read more

Go to the first instruction in block.

Go to the last instruction in block.

Go to the top of block which must be inserted into the layout. At this position, instructions cannot be inserted, but next_inst() will move to the first instruction in block. Read more

Go to the bottom of block which must be inserted into the layout. At this position, inserted instructions will be appended to block. Read more

Go to the top of the next block in layout order and return it. Read more

Go to the bottom of the previous block in layout order and return it. Read more

Move to the next instruction in the same block and return it. Read more

Move to the previous instruction in the same block and return it. Read more

Insert an instruction at the current position. Read more

Remove the instruction under the cursor. Read more

Remove the instruction under the cursor. Read more

Insert a block at the current position and switch to it. Read more

Get an immutable reference to the data flow graph.

Get a mutable reference to the data flow graph.

Insert a new instruction which belongs to the DFG.
