From aba0e740f25ffa5c338dfa76cab71144802cebc2 Mon Sep 17 00:00:00 2001 From: Xavier Leroy Date: Sun, 21 Jun 2020 18:22:00 +0200 Subject: Replace `omega` tactic with `lia` Since Coq 8.12, `omega` is flagged as deprecated and scheduled for removal. Also replace CompCert's homemade tactics `omegaContradiction`, `xomega`, and `xomegaContradiction` with `lia` and `extlia`. Turn back on the deprecation warning for uses of `omega`. Make the proof of `Ctypes.sizeof_pos` more robust to variations in `lia`. --- cfrontend/Clight.v | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'cfrontend/Clight.v') diff --git a/cfrontend/Clight.v b/cfrontend/Clight.v index 8ab29fe9..239ca370 100644 --- a/cfrontend/Clight.v +++ b/cfrontend/Clight.v @@ -739,7 +739,7 @@ Proof. exploit external_call_receptive; eauto. intros [vres2 [m2 EC2]]. exists (Returnstate vres2 k m2). econstructor; eauto.
