Update
2002-09-10 Hartvig Ekner <hartvige@mips.com> * sysdeps/mips/memcpy.S: New file. * sysdeps/mips/memset.S: New file. * sysdeps/mips/fpu/e_sqrt.c: New file. * sysdeps/mips/fpu/e_sqrtf.c: New file. * fpu/fclrexcpt.c: Cleaned up the FPU exception stuff - was not functional before. Also removed all SHLIB_COMPAT stuff. * fpu/fegetenv.c: Likewise. * fpu/fesetenv.c:: Likewise. * fpu/feupdateenv.c: Likewise. * fpu/fgetexcptflg.c: Likewise. * fpu/fraiseexcpt.c: Likewise. * sysdeps/mips/fpu/fsetexcptflg.c: New file.
