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 --- lib/Camlcoq.ml | 9 +++++++-- 1 file changed, 7 insertions(+), 2 deletions(-) (limited to 'lib/Camlcoq.ml') diff --git a/lib/Camlcoq.ml b/lib/Camlcoq.ml index 8d6fd243..dd896367 100644 --- a/lib/Camlcoq.ml +++ b/lib/Camlcoq.ml @@ -320,9 +320,14 @@ let coqstring_of_camlstring s = (* Floats *) let coqfloat_of_camlfloat f = - Float.double_of_bits(coqint_of_camlint64(Int64.bits_of_float f)) + Float.of_bits(coqint_of_camlint64(Int64.bits_of_float f)) let camlfloat_of_coqfloat f = - Int64.float_of_bits(camlint64_of_coqint(Float.bits_of_double f)) + Int64.float_of_bits(camlint64_of_coqint(Float.to_bits f)) + +let coqfloat32_of_camlfloat f = + Float32.of_bits(coqint_of_camlint(Int32.bits_of_float f)) +let camlfloat_of_coqfloat32 f = + Int32.float_of_bits(camlint_of_coqint(Float32.to_bits f)) (* Int31 *) -- cgit
