From 9686a2e668aad033ef12b48c2d1e7f1ce6796838 Mon Sep 17 00:00:00 2001 From: Joseph Myers Date: Mon, 8 Sep 2014 13:22:56 +0100 Subject: Remove no-longer-needed fp-bit target macros. gcc: * defaults.h (LARGEST_EXPONENT_IS_NORMAL, ROUND_TOWARDS_ZERO): Remove. * doc/tm.texi.in (ROUND_TOWARDS_ZERO, LARGEST_EXPONENT_IS_NORMAL): Remove. * doc/tm.texi: Regenerate. * system.h (LARGEST_EXPONENT_IS_NORMAL, ROUND_TOWARDS_ZERO): Poison. * config/arm/arm.h (LARGEST_EXPONENT_IS_NORMAL): Remove. * config/cris/cris.h (__make_dp): Remove. libgcc: * fp-bit.c (pack_d, unpack_d): Remove LARGEST_EXPONENT_IS_NORMAL and ROUND_TOWARDS_ZERO conditionals.
