Back in 1999, Torbjorn Granlund posted: http://gcc.gnu.org/ml/gcc/1999-07n/msg00553.html
That message contains an IEEE floating-point emulation library, like fp-bit.c. Howeve, the performance is considerably better; Joseph measured against fp-bit.c with a modern compiler, and ieeelib.c is about 10-15% better than the current code on EEMBC on a PowerPC 440. So, we're considering doing what it takes to get ieeelib.c into GCC, or, perhaps, borrowing some of its ideas for fp-bit.c. In his original message, Torbjorn indicated that Swox AB (the company of which he is CEO) donated the code, and the old copyright file had an entry for Torbjorn, though not Swox AB. I've contacted Torbjorn, and he'd still like to see ieeelib.c in GCC. Is there any copyright issue that would prevent inclusion of this code? Assuming all the technical bits were in order, would we need to get the FSF involved in any way before including the code? Thanks, -- Mark Mitchell CodeSourcery, LLC [EMAIL PROTECTED] (916) 791-8304
