Description |
Execute a given matcher table and return true if the match was successful and false otherwise. |
|
|
|
Return true if the specified operand is a G_PTR_ADD with a G_CONSTANT on the right‐hand side. GlobalISel's separation of pointer and integer types means that we don't need to worry about G_OR with equivalent semantics. |
|
Return true if MI can obviously be folded into IntoMI. MI and IntoMI do not need to be in the same basic blocks, but MI must preceed IntoMI. |
