* math/test-misc.c (main): Add tests for rounding long double
values close to smallest double denormalized value to double. * soft-fp/op-common.h (FP_TRUNC): Correct off-by-one error in condition for truncating to 0. Set sticky bit for such truncation. 2007-05-03 Jakub Jelinek <jakub@redhat.com> * math/test-misc.c (main): Add tests for rounding long double values close to smallest double denormalized value to double. 2007-04-30 Joseph Myers <joseph@codesourcery.com> * soft-fp/op-common.h (FP_TRUNC): Correct off-by-one error in condition for truncating to 0.
