From c52ec94809807483ddf593e370daabb68f57a772 Mon Sep 17 00:00:00 2001 From: Janis Johnson Date: Tue, 6 Jan 2009 19:02:41 +0000 Subject: re PR c/34252 (DEC32_MIN_EXP, DEC32_MAX_EXP don't match TR 24732) gcc/ PR c/34252 * ginclude/float.h: Rename DECnn_DEN to DECnn_SUBNORMAL_MIN. * real.c (decimal_single_format): Correct values of emin and emax. (decimal_double_format): Ditto. (decimal_quad_format): Ditto. * c-cppbuiltin.c (builtin_define_decimal_float_constants): Adjust computation of DECnn_MIN and DECnn_MAX for corrected values of emin and emax. Define __DECnn_SUBNORMAL_MIN__ instead of __DECnn_MIN__, and adjust its computation for the corrected value of emin. gcc/testsuite/ PR c/34252 * gcc.dg/dfp/decfloat-constants.c: Check for DECnn_SUBNORMAL_MIN instead of DECnn_DEN. Support -DDBG to list lines that fail.
