Support floating point in e

archive


This package include basic floating point support for e.  It consists of an e wrapper for c floating point library that needs to be compiled into Specman order to be used.  A makefile is provided to accomplish that.  This is useful for people who want to do operations with real numbers in e.

  • I'm getting segmentation faults when I try to use this package on a 64 bit platform (64 bit SUSE linux on x86-64). Have you observed this? It's pretty easy to create the seg fault case, here's some example code:

    <'
    import vrst_snfp;
    extend sys {
    run() is also {
    var fpfn : snfp_floating_point_function_s = new;
    fpfn.op1.set("0.0");
    fpfn.op2.set("0.1");
    fpfn.its_type= FADD;
    fpfn.do_fp();
    outf("%s",fpfn.res.to_str());
    };
    };
    '>

    The seg fault occurs on the outf, when Specman attempts to access the .res field of fpfn. Any help would be much appreciated!
