From e0f7170a43480e2fb81925223facd5eab6b27617 Mon Sep 17 00:00:00 2001 From: Geoff Keating Date: Mon, 11 Sep 2000 06:03:02 +0000 Subject: [PATCH] sysv4.h (MASK_LONG_DOUBLE_128): Define. * config/rs6000/sysv4.h (MASK_LONG_DOUBLE_128): Define. (TARGET_LONG_DOUBLE_128): Define. (SUBTARGET_SWITCHES): Add -mlong-double-64 and -mlong-double-128. (LONG_DOUBLE_TYPE_SIZE): Redefine. (MAX_LONG_DOUBLE_TYPE_SIZE): Define. (LIBGCC2_LONG_DOUBLE_TYPE_SIZE): Define depending on definition of __LONG_DOUBLE_128__. (CPP_SYSV_SPEC): Define __LONG_DOUBLE_128__ if -mlong-double-128 passed. (CPP_LONGDOUBLE_DEFAULT_SPEC): Define. (CPP_SYSV_DEFAULT_SPEC): Define. (SUBTARGET_EXTRA_SPECS): Add cpp_longdouble_default. (INIT_TARGET_OPTABS): Define.
