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 --- cfrontend/SimplLocals.v | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-) (limited to 'cfrontend/SimplLocals.v') diff --git a/cfrontend/SimplLocals.v b/cfrontend/SimplLocals.v index 29565089..9c529280 100644 --- a/cfrontend/SimplLocals.v +++ b/cfrontend/SimplLocals.v @@ -45,7 +45,8 @@ Definition make_cast (a: expr) (tto: type) : expr := match classify_cast (typeof a) tto with | cast_case_neutral => a | cast_case_i2i I32 _ => a - | cast_case_f2f F64 => a + | cast_case_f2f => a + | cast_case_s2s => a | cast_case_l2l => a | cast_case_struct _ _ _ _ => a | cast_case_union _ _ _ _ => a @@ -59,6 +60,7 @@ Fixpoint simpl_expr (cenv: compilenv) (a: expr) : expr := match a with | Econst_int _ _ => a | Econst_float _ _ => a + | Econst_single _ _ => a | Econst_long _ _ => a | Evar id ty => if VSet.mem id cenv then Etempvar id ty else Evar id ty | Etempvar id ty => Etempvar id ty @@ -157,6 +159,7 @@ Fixpoint addr_taken_expr (a: expr): VSet.t := match a with | Econst_int _ _ => VSet.empty | Econst_float _ _ => VSet.empty + | Econst_single _ _ => VSet.empty | Econst_long _ _ => VSet.empty | Evar id ty => VSet.empty | Etempvar id ty => VSet.empty -- cgit
