Raw Normal View History

floating point environment, untested at present the i386 code does not support sse floating point, which is not part of the standard i386 abi. while it may be desirable to support it later, doing so will reduce performance and require some tricks to probe if sse support is present. this first commit is i386-only, but it should be trivial to port the asm to x86_64.
