From 002f0b0b5df92cc1c1302c6b95c0c97fd986ed94 Mon Sep 17 00:00:00 2001 From: Jakub Jelinek Date: Thu, 3 May 2007 12:15:04 +0000 Subject: * 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 * 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 * soft-fp/op-common.h (FP_TRUNC): Correct off-by-one error in condition for truncating to 0.
