If we think this is really true, we could move to using include/math- emu/* instead of the files in powerpc/math-emu. The problem I had was when I tried to recreate the history of the code in powerpc/math-emu and how it doesn't really match the glibc code base. There are some differences and I wasn't sure if they were do to trying to match PPC HW at a bit level or not. I was hoping that the work Liu Yu would get as a bit of a testsuite to see if there was any harm in moving over to include/math-emu. - k _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-dev
