From e57aab0559297cff3875931258674cfe2cfbbba3 Mon Sep 17 00:00:00 2001 From: Maxime Dénès Date: Thu, 30 Jun 2016 14:22:02 +0200 Subject: Separate flags for fix/cofix/match reduction and clean reduction function names. This is a reimplementation of Hugo's PR#117. We are trying to address the problem that the name of some reduction functions was not saying what they were doing (e.g. whd_betadeltaiota was doing let-in reduction). Like PR#117, we are careful that no function changed semantics without changing the names. Porting existing ML code should be a matter of renamings a few function calls. Also, we introduce more precise reduction flags fMATCH, fFIX, fCOFIX collectively denominated iota. We renamed the following functions: Closure.betadeltaiota -> Closure.all Closure.betadeltaiotanolet -> Closure.allnolet Reductionops.beta -> Closure.beta Reductionops.zeta -> Closure.zeta Reductionops.betaiota -> Closure.betaiota Reductionops.betaiotazeta -> Closure.betaiotazeta Reductionops.delta -> Closure.delta Reductionops.betalet -> Closure.betazeta Reductionops.betadelta -> Closure.betadeltazeta Reductionops.betadeltaiota -> Closure.all Reductionops.betadeltaiotanolet -> Closure.allnolet Closure.no_red -> Closure.nored Reductionops.nored -> Closure.nored Reductionops.nf_betadeltaiota -> Reductionops.nf_all Reductionops.whd_betadelta -> Reductionops.whd_betadeltazeta Reductionops.whd_betadeltaiota -> Reductionops.whd_all Reductionops.whd_betadeltaiota_nolet -> Reductionops.whd_allnolet Reductionops.whd_betadelta_stack -> Reductionops.whd_betadeltazeta_stack Reductionops.whd_betadeltaiota_stack -> Reductionops.whd_all_stack Reductionops.whd_betadeltaiota_nolet_stack -> Reductionops.whd_allnolet_stack Reductionops.whd_betadelta_state -> Reductionops.whd_betadeltazeta_state Reductionops.whd_betadeltaiota_state -> Reductionops.whd_all_state Reductionops.whd_betadeltaiota_nolet_state -> Reductionops.whd_allnolet_state Reductionops.whd_eta -> Reductionops.shrink_eta Tacmach.pf_whd_betadeltaiota -> Tacmach.pf_whd_all Tacmach.New.pf_whd_betadeltaiota -> Tacmach.New.pf_whd_all And removed the following ones: Reductionops.whd_betaetalet Reductionops.whd_betaetalet_stack Reductionops.whd_betaetalet_state Reductionops.whd_betadeltaeta_stack Reductionops.whd_betadeltaeta_state Reductionops.whd_betadeltaeta Reductionops.whd_betadeltaiotaeta_stack Reductionops.whd_betadeltaiotaeta_state Reductionops.whd_betadeltaiotaeta They were unused and having some reduction functions perform eta is confusing as whd_all and nf_all don't do it. --- proofs/clenv.ml | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'proofs/clenv.ml') diff --git a/proofs/clenv.ml b/proofs/clenv.ml index 853410db8..ef3845857 100644 --- a/proofs/clenv.ml +++ b/proofs/clenv.ml @@ -72,7 +72,7 @@ let clenv_get_type_of ce c = Retyping.get_type_of (cl_env ce) (cl_sigma ce) c exception NotExtensibleClause let clenv_push_prod cl = - let typ = whd_betadeltaiota (cl_env cl) (cl_sigma cl) (clenv_type cl) in + let typ = whd_all (cl_env cl) (cl_sigma cl) (clenv_type cl) in let rec clrec typ = match kind_of_term typ with | Cast (t,_,_) -> clrec t | Prod (na,t,u) -> -- cgit v1.2.3
