Expand description

An indication of where we are in the control flow graph. Used for printing extra information in dump_mir

Variants§

§

BeforeCFG

We have not started dumping the control flow graph, but we are about to.

§

AfterCFG

We just finished dumping the control flow graph. This is right before EOF

§

BeforeBlock(BasicBlock)

We are about to start dumping the given basic block.

§

BeforeLocation(Location)

We are just about to dump the given statement or terminator.

§

AfterLocation(Location)

We just dumped the given statement or terminator.

§

AfterTerminator(BasicBlock)

We just dumped the terminator for a block but not the closing }.
