------- Comment #5 from pinskia at gcc dot gnu dot org 2006-08-06 04:46 ------- Also one comment about your patch for soft-fp: + /* Wrap the sequence in REG_LIBCALL / REG_RETVAL notes so that loop + invariant code motion can move it. */
The tree level loop invariant motion should have moved it already. Why use LIBCALL here when we are already trying to remove it? -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=28618
