* Use PowerPC 64 bits instructions (when available) for int<->FP conversions.Xavier Leroy2015-09-131-1/+1
| | | | | | Also: implement __builtin_isel on non-EREF platforms with a branch-free instruction sequence. Also: extend ./configure so that it recognizes "ppc64-" and "e5500-" platforms in addition to "ppc-".
* Merge of "newspilling" branch:xleroy2014-07-231-4/+4
| | | | | | | | | | | | | | | - 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
