Reduction expressions

The parsing produces initially a list of red_atom

type 'a red_atom =
  1. | FBeta
  2. | FMatch
  3. | FFix
  4. | FCofix
  5. | FZeta
  6. | FConst of 'a list
  7. | FDeltaBut of 'a list
  8. | FHead

This list of atoms is immediately converted to a glob_red_flag

type strength =
  1. | Norm
  2. | Head
type 'a glob_red_flag = {
  1. rStrength : strength;
  2. rBeta : bool;
  3. rMatch : bool;
  4. rFix : bool;
  5. rCofix : bool;
  6. rZeta : bool;
  7. rDelta : bool;
    (*

    true = delta all but rConst; false = delta only on rConst

    *)
  8. rConst : 'a list;
}

Generic kinds of reductions

type ('a, 'b, 'c, 'flags) red_expr_gen0 =
  1. | Red
  2. | Hnf
  3. | Simpl of 'flags * ('b, 'c) Util.union Locus.with_occurrences option
  4. | Cbv of 'flags
  5. | Cbn of 'flags
  6. | Lazy of 'flags
  7. | Unfold of 'b Locus.with_occurrences list
  8. | Fold of 'a list
  9. | Pattern of 'a Locus.with_occurrences list
  10. | ExtraRedExpr of string
  11. | CbvVm of ('b, 'c) Util.union Locus.with_occurrences option
  12. | CbvNative of ('b, 'c) Util.union Locus.with_occurrences option
type ('a, 'b, 'c) red_expr_gen = ('a, 'b, 'c, 'b glob_red_flag) red_expr_gen0
type ('a, 'b, 'c) may_eval =
  1. | ConstrTerm of 'a
  2. | ConstrEval of ('a, 'b, 'c) red_expr_gen * 'a
  3. | ConstrContext of Names.lident * 'a
  4. | ConstrTypeOf of 'a
type raw_red_expr = (r_trm, r_cst, r_pat) red_expr_gen
type 'a and_short_name = 'a * Names.lident option
type glob_red_expr = (g_trm, g_cst, g_pat) red_expr_gen
