From 2a0168fea37b68ad14e2cb60bf215111e49d4870 Mon Sep 17 00:00:00 2001 From: xleroy Date: Wed, 23 Jul 2014 08:54:56 +0000 Subject: Merge of "newspilling" branch: - Support single-precision floats as first-class values - Introduce chunks Many32, Many64 and types Tany32, Tany64 to support saving and restoring registers without knowing the exact types (int/single/float) of their contents, just their sizes. - Memory model: generalize the opaque encoding of pointers to apply to any value, not just pointers, if chunks Many32/Many64 are selected. - More properties of FP arithmetic proved. git-svn-id: https://yquem.inria.fr/compcert/svn/compcert/trunk@2537 fca1b0fc-160b-0410-b1d3-a4f43f01ea2e --- backend/Constpropproof.v | 2 ++ 1 file changed, 2 insertions(+) (limited to 'backend/Constpropproof.v') diff --git a/backend/Constpropproof.v b/backend/Constpropproof.v index ecae5dc6..b79c721e 100644 --- a/backend/Constpropproof.v +++ b/backend/Constpropproof.v @@ -159,6 +159,8 @@ Proof. inv H. inv H0. exists (Vint n); auto. - (* float *) destruct (Compopts.generate_float_constants tt); inv H. inv H0. exists (Vfloat f); auto. +- (* single *) + destruct (Compopts.generate_float_constants tt); inv H. inv H0. exists (Vsingle f); auto. - (* pointer *) destruct p; try discriminate. + (* global *) -- cgit
