* Revert suppression of __builtin_{read,write}_reversed for x86 and ARM,xleroy2013-04-291-28/+35
| | | | | | | | for compatibility with earlier CompCert versions. But don't use them in PackedStructs. git-svn-id: https://yquem.inria.fr/compcert/svn/compcert/trunk@2216 fca1b0fc-160b-0410-b1d3-a4f43f01ea2e
* Add __builtin_bswap16 and __builtin_bswap32 to all ports.xleroy2013-04-201-15/+35
| | | | | | | | | Remove __builtin_{read,write}_reversed from IA32 and ARM ports. Machregs: tighten destroyed_by_builtin Packedstructs: use bswap if read/write-reversed not available. git-svn-id: https://yquem.inria.fr/compcert/svn/compcert/trunk@2208 fca1b0fc-160b-0410-b1d3-a4f43f01ea2e
