create base/fenv.c to standerdize fenv across platforms. It's a c file and not a cpp file because c99
(which defines fenv) doesn't necessarily extend to c++ and it is a problem with solaris. If really desired this could wrap the ieeefp interface found in bsd* as well, but I see no need at the moment. src/arch/alpha/isa/fp.isa: src/arch/sparc/isa/formats/basic.isa: use m5_fesetround()/m5_fegetround() istead of fenv interface directly src/arch/sparc/isa/includes.isa: use base/fenv instead of fenv directly src/base/SConscript: add fenv to sconscript src/base/fenv.hh: src/base/random.cc: m5 implementation to standerdize fenv across platforms. --HG-- extra : convert_revision : 38d2629affd964dcd1a5ab0db4ac3cb21438e72c
