4Subject: [PATCH] * config/i386/i386.md (*movxf_internal): Disable CONST_DOUBLE
5 optimization for CM_MEDIUM and CM_LARGE code models. Fix usage
6 of standard_80387_constant_p.
7 (*movxf_internal_nointeger): Ditto.
8 (*movdf_internal): Remove dead code-size optimization.
9 (*movdf_internal_rex64): Fix usage of standard_80387_constant_p.
10 (*movdf_internal_nointeger): Ditto.
11 (*movsf_internal): Ditto.
12 (floating point move splitters): Ditto.
13 * config/i386/constraints.md (G): Ditto.
14 * config/i386/i386.c (ix86_preferred_reload_class): Ditto.
