DiffConstants¶

public final class DiffConstants¶: Constants used during differentiation.

Fields¶

ADJOINT¶

protected static final int ADJOINT¶

ADJOINT_BWD¶

protected static final int ADJOINT_BWD¶

ADJOINT_FWD¶

protected static final int ADJOINT_FWD¶

ADJOINT_MODE¶

protected static final int ADJOINT_MODE¶

ADJOINT_SPLIT_MODE¶

protected static final int ADJOINT_SPLIT_MODE¶

ALT_DIFF_VAR¶

protected static final int ALT_DIFF_VAR¶: The index where we store an alternate diff name of a given variable. For instance for v, the std diff var may be vb, and me may need another diff var vb0 for instance for storing a previous value of vb…

BINOMIAL_LOOP¶

protected static final int BINOMIAL_LOOP¶

CHECKPOINT¶

protected static final int CHECKPOINT¶

COPY_DIFF_VAR¶

protected static final int COPY_DIFF_VAR¶

DIFFERENTIATED¶

protected static final int DIFFERENTIATED¶

DO_LOOP¶

protected static final int DO_LOOP¶

ENTRY_BLOCK¶

protected static final int ENTRY_BLOCK¶

FIXEDPOINT_LOOP¶

protected static final int FIXEDPOINT_LOOP¶

II_LOOP¶

protected static final int II_LOOP¶

INCALL¶

protected static final int INCALL¶

INCREMENT_VARIABLE¶

protected static final int INCREMENT_VARIABLE¶: Constants for the “kind” of differentiated statement.

INEXPR¶

protected static final int INEXPR¶: The possible values for the (stacked) contexts in which variables must be differentiated. May be INEXPR (default), INCALL, INHEADER

INHEADER¶

protected static final int INHEADER¶

LABELLED_REGION¶

protected static final int LABELLED_REGION¶

MOD¶

protected static final int MOD¶

MULTITHREAD_REGION¶

protected static final int MULTITHREAD_REGION¶

NATURAL_LOOP¶

protected static final int NATURAL_LOOP¶

NODIFF¶

protected static final int NODIFF¶

ORIGCOPY¶

protected static final int ORIGCOPY¶

PLAIN¶

protected static final int PLAIN¶

PLAIN_BLOCK¶

protected static final int PLAIN_BLOCK¶: Constants for the “kind” of FlowGraphLevel.

PLAIN_GROUP¶

protected static final int PLAIN_GROUP¶

PROC¶

protected static final int PROC¶

SET_VARIABLE¶

protected static final int SET_VARIABLE¶

TANGENT¶

protected static final int TANGENT¶

TANGENT_MODE¶

protected static final int TANGENT_MODE¶: The current mode of differentiation for the current unit. - in TANGENT_MODE we generate procedure FOO_D. - in ADJOINT_SPLIT_MODE we generate the two procedures FOO_FWD and FOO_BWD. - in ADJOINT_MODE we generate procedure FOO_B. ADJOINT_MODE also includes “CONTEXT” mode, where we only build a context from which to call the differentiated code.

TIMES_LOOP¶

protected static final int TIMES_LOOP¶

TOP_LEVEL¶

protected static final int TOP_LEVEL¶

TYPE¶

protected static final int TYPE¶

UNDEFSORT¶

protected static final int UNDEFSORT¶: The different sorts of differentiated Units or Variables that we may create. This integer is also the rank in the arrays of all such differentiated objects. Reserve -1 for UNDEFINED.

VAR¶

protected static final int VAR¶: Ranks in suffixes array.

WHILE_LOOP¶

protected static final int WHILE_LOOP¶

WILD_LOOP¶

protected static final int WILD_LOOP¶
