From 7773dca7d22dad2a9e6d2385584411308913ab1b Mon Sep 17 00:00:00 2001 From: Richard Sandiford Date: Tue, 5 Sep 2017 19:57:09 +0000 Subject: (decimal_)float_mode_for_size in real.h This patch makes the binary float macros in real.h use float_mode_for_size and adds a corresponding decimal_float_mode_for_size for the decimal macros. 2017-09-05 Richard Sandiford gcc/ * machmode.h (decimal_float_mode_for_size): New function. * real.h (REAL_VALUE_TO_TARGET_LONG_DOUBLE): Use float_mode_for_size. (REAL_VALUE_TO_TARGET_DOUBLE): Likewise. (REAL_VALUE_TO_TARGET_SINGLE): Likewise. (REAL_VALUE_TO_TARGET_DECIMAL128): Use decimal_float_mode_for_size. (REAL_VALUE_TO_TARGET_DECIMAL64): Likewise. (REAL_VALUE_TO_TARGET_DECIMAL32): Likewise.
