From fc2613e871dffffa788d90044a81598f671d0a3b Mon Sep 17 00:00:00 2001 From: letouzey Date: Thu, 5 Jul 2012 16:56:16 +0000 Subject: ZArith + other : favor the use of modern names instead of compat notations - For instance, refl_equal --> eq_refl - Npos, Zpos, Zneg now admit more uniform qualified aliases N.pos, Z.pos, Z.neg. - A new module BinInt.Pos2Z with results about injections from positive to Z - A result about Z.pow pushed in the generic layer - Zmult_le_compat_{r,l} --> Z.mul_le_mono_nonneg_{r,l} - Using tactic Z.le_elim instead of Zle_lt_or_eq - Some cleanup in ring, field, micromega (use of "Equivalence", "Proper" ...) - Some adaptions in QArith (for instance changed Qpower.Qpower_decomp) - In ZMake and ZMake, functor parameters are now named NN and ZZ instead of N and Z for avoiding confusions git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@15515 85f007b7-540e-0410-9357-904b9bb8a0f7 --- theories/FSets/FSetBridge.v | 4 ++-- theories/FSets/FSetEqProperties.v | 8 ++++---- theories/FSets/FSetFacts.v | 6 ++---- theories/FSets/FSetProperties.v | 2 +- 4 files changed, 9 insertions(+), 11 deletions(-) (limited to 'theories/FSets') diff --git a/theories/FSets/FSetBridge.v b/theories/FSets/FSetBridge.v index 25ce5577e..f0a588379 100644 --- a/theories/FSets/FSetBridge.v +++ b/theories/FSets/FSetBridge.v @@ -165,7 +165,7 @@ Module DepOfNodep (Import M: S) <: Sdep with Module E := M.E. case (for_all (fdec Pdec) s); unfold For_all in |- *; [ left | right ]; intros. assert (compat_bool E.eq (fdec Pdec)); auto. - generalize (H0 H3 (refl_equal _) _ H2). + generalize (H0 H3 Logic.eq_refl _ H2). unfold fdec in |- *. case (Pdec x); intuition. inversion H4. @@ -230,7 +230,7 @@ Module DepOfNodep (Import M: S) <: Sdep with Module E := M.E. unfold fdec in |- *; case (Pdec x); intuition. change ((fun x => negb (fdec Pdec x)) x = true) in |- *. apply (filter_2 (s:=s) (x:=x)); auto. - set (b := fdec Pdec x) in *; generalize (refl_equal b); + set (b := fdec Pdec x) in *; generalize (Logic.eq_refl b); pattern b at -1 in |- *; case b; unfold b in |- *; [ left | right ]. elim (H4 x); intros _ B; apply B; auto with set. diff --git a/theories/FSets/FSetEqProperties.v b/theories/FSets/FSetEqProperties.v index 755bc7dd0..ac495c040 100644 --- a/theories/FSets/FSetEqProperties.v +++ b/theories/FSets/FSetEqProperties.v @@ -206,7 +206,7 @@ intros. generalize (@choose_1 s) (@choose_2 s). destruct (choose s);intros. exists e;auto with set. -generalize (H1 (refl_equal None)); clear H1. +generalize (H1 Logic.eq_refl); clear H1. intros; rewrite (is_empty_1 H1) in H; discriminate.
