* - Recognize __builtin_fabs as an operator, not just a builtin,Gravatar xleroy2013-11-06
| | | | | | | | | enabling more aggressive optimizations. - Less aggressive CSE for EF_builtin builtins, causes problems for __builtin_write{16,32}_reversed. git-svn-id: https://yquem.inria.fr/compcert/svn/compcert/trunk@2363 fca1b0fc-160b-0410-b1d3-a4f43f01ea2e
