| | | | | | | | | literals. This is a follow-up to commit 350354c. - Move Float.build_from_parsed to Fappli_IEEE_extra.Bparse - Add early checks for overflow and underflow and prove them correct. - Improve speed of Bparse by using a fast exponentiation (square-and-multiply).

- 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
