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/ValueAnalysis.v | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'backend/ValueAnalysis.v') diff --git a/backend/ValueAnalysis.v b/backend/ValueAnalysis.v index e293028d..813944d6 100644 --- a/backend/ValueAnalysis.v +++ b/backend/ValueAnalysis.v @@ -166,7 +166,7 @@ Definition store_init_data (ab: ablock) (p: Z) (id: init_data) : ablock := | Init_int32 n => ablock_store Mint32 ab p (I n) | Init_int64 n => ablock_store Mint64 ab p (L n) | Init_float32 n => ablock_store Mfloat32 ab p - (if propagate_float_constants tt then F n else ftop) + (if propagate_float_constants tt then FS n else ftop) | Init_float64 n => ablock_store Mfloat64 ab p (if propagate_float_constants tt then F n else ftop) | Init_addrof symb ofs => ablock_store Mint32 ab p (Ptr (Gl symb ofs)) @@ -922,7 +922,7 @@ Proof. eapply VMTOP; eauto. - exploit BC'INV; eauto. intros (b'' & delta & J'). exploit Mem.loadbytes_inject. eexact IMEM. eauto. eauto. intros (bytes & A & B). - inv B. inv H3. eapply PMTOP; eauto. + inv B. inv H3. inv H7. eapply PMTOP; eauto. } (* Conclusions *) exists bc'; splitall. -- cgit
