- // Reschedule DBG_VALUEs to match any loads that were moved. When a load is
- // sunk beyond a DBG_VALUE that is referring to it, the DBG_VALUE becomes a
- // use-before-def, resulting in a loss of debug info.
-
- // Example:
- // Before the Pre Register Allocation Load Store Pass
- // inst_a
- // %2 = ld ...
- // inst_b
- // DBG_VALUE %2, "x", ...
- // %3 = ld ...
-
- // After the Pass:
- // inst_a
- // inst_b
- // DBG_VALUE %2, "x", ...
- // %2 = ld ...
- // %3 = ld ...
-
- // The code below addresses this by moving the DBG_VALUE to the position
- // immediately after the load.
-
- // Example:
- // After the code below:
- // inst_a
- // inst_b
- // %2 = ld ...
- // DBG_VALUE %2, "x", ...
- // %3 = ld ...
-
- // The algorithm works in two phases: First RescheduleOps() populates the
- // RegisterMap with registers that were moved as keys, there is no value
- // inserted. In the next phase, every MachineInstr in a basic block is
- // iterated over. If it is a valid DBG_VALUE or DBG_VALUE_LIST and it uses one
- // or more registers in the RegisterMap, the RegisterMap and InstrMap are
- // populated with the MachineInstr. If the DBG_VALUE or DBG_VALUE_LIST
- // describes debug information for a variable that already exists in the
- // DbgValueSinkCandidates, the MachineInstr in the DbgValueSinkCandidates must
- // be set to undef. If the current MachineInstr is a load that was moved,
- // undef the corresponding DBG_VALUE or DBG_VALUE_LIST and clone it to below
- // the load.
-
- // To illustrate the above algorithm visually let's take this example.
-
- // Before the Pre Register Allocation Load Store Pass:
- // %2 = ld ...
- // DBG_VALUE %2, A, .... # X
- // DBG_VALUE 0, A, ... # Y
- // %3 = ld ...
- // DBG_VALUE %3, A, ..., # Z
- // %4 = ld ...
-
- // After Pre Register Allocation Load Store Pass:
- // DBG_VALUE %2, A, .... # X
- // DBG_VALUE 0, A, ... # Y
- // DBG_VALUE %3, A, ..., # Z
- // %2 = ld ...
- // %3 = ld ...
- // %4 = ld ...
-
- // The algorithm below does the following:
-
- // In the beginning, the RegisterMap will have been populated with the virtual
- // registers %2, and %3, the DbgValueSinkCandidates and the InstrMap will be
- // empty. DbgValueSinkCandidates = {}, RegisterMap = {2 -> {}, 3 -> {}},
- // InstrMap {}
- // -> DBG_VALUE %2, A, .... # X
- // DBG_VALUE 0, A, ... # Y
- // DBG_VALUE %3, A, ..., # Z
- // %2 = ld ...
- // %3 = ld ...
- // %4 = ld ...
-
- // After the first DBG_VALUE (denoted with an X) is processed, the
- // DbgValueSinkCandidates and InstrMap will be populated and the RegisterMap
- // entry for %2 will be populated as well. DbgValueSinkCandidates = {A -> X},
- // RegisterMap = {2 -> {X}, 3 -> {}}, InstrMap {X -> 2} DBG_VALUE %2, A, ....
- // # X
- // -> DBG_VALUE 0, A, ... # Y
- // DBG_VALUE %3, A, ..., # Z
- // %2 = ld ...
- // %3 = ld ...
- // %4 = ld ...
-
- // After the DBG_VALUE Y is processed, the DbgValueSinkCandidates is updated
- // to now hold Y for A and the RegisterMap is also updated to remove X from
- // %2, this is because both X and Y describe the same debug variable A. X is
- // also updated to have a $noreg as the first operand. DbgValueSinkCandidates
- // = {A -> {Y}}, RegisterMap = {2 -> {}, 3 -> {}}, InstrMap = {X
- // -> 2}
- // DBG_VALUE $noreg, A, .... # X
- // DBG_VALUE 0, A, ... # Y
- // -> DBG_VALUE %3, A, ..., # Z
- // %2 = ld ...
- // %3 = ld ...
- // %4 = ld ...
-
- // After DBG_VALUE Z is processed, the DbgValueSinkCandidates is updated to
- // hold Z fr A, the RegisterMap is updated to hold Z for %3, and the InstrMap
- // is updated to have Z mapped to %3. This is again because Z describes the
- // debug variable A, Y is also updated to have a $noreg as the first operand.
- // DbgValueSinkCandidates = {A -> {Z}}, RegisterMap = {2 -> {}, 3 -> {Z}},
- // InstrMap = {X
- // -> 2, Z -> 3}
- // DBG_VALUE $noreg, A, .... # X
- // DBG_VALUE $noreg, A, ... # Y
- // DBG_VALUE %3, A, ..., # Z
- // -> %2 = ld ...
- // %3 = ld ...
- // %4 = ld ...
-
- // Nothing happens here since the RegisterMap for %2 contains no value.
- // DbgValueSinkCandidates = {A -> {Z}}, RegisterMap = {2 -> {}, 3 -> {Z}},

- // DBG_VALUE $noreg, A, .... # X

- // DBG_VALUE %3, A, ..., # Z
- // %2 = ld ...

-
- // Since the RegisterMap contains Z as a value for %3, the MachineInstr
- // pointer Z is moved to come after the load for %3 and the Basic Block
- // iterator is moved to after the DBG_VALUE Z's new position.
- // DbgValueSinkCandidates = {A -> {Z}}, RegisterMap = {2 -> {}, 3 -> {Z}},
