Hi !! I want to use the MULTILIB feature for my powerpc gnu compiler. The question is how I have to work with this key words ? The only info which I has found is the paper http://gcc.gnu.org/onlinedocs/gccint/Target-Fragment.html , but I need mor info and I didn't find every keyword which I found in serveral t-files. (e.g. MULTILIB_HARDFLOAT_ONLY and MULTILIB_SOFTFLOAT_ONLY (see gcc/config/rs6000/t-rtems ) ) Another important point for me are the meening of the asterisks ('*'). So how can explain the following line MULTILIB_EXCEPTIONS = ... mcpu=7400/maltivec \ *mcpu=7400/*mspe=no* ... How I should decode the asterisk befor the mcpu option and why has the mspe=no option two asterisks ???
