[Patch 6/17] Migrate excess precision logic to use TARGET_EXCESS_PRECISION
gcc/
* toplev.c (init_excess_precision): Delete most logic.
* tree.c (excess_precision_type): Rewrite to use
TARGET_EXCESS_PRECISION.
* doc/invoke.texi (-fexcess-precision): Document behaviour in a
more generic fashion.
* ginclude/float.h: Wrap definition of FLT_EVAL_METHOD in
__STDC_WANT_IEC_60559_TYPES_EXT__.
gcc/c-family/
* c-common.c (excess_precision_mode_join): New.
(c_ts18661_flt_eval_method): New.
(c_c11_flt_eval_method): Likewise.
(c_flt_eval_method): Likewise.
* c-common.h (excess_precision_mode_join): New.
(c_flt_eval_method): Likewise.
* c-cppbuiltin.c (c_cpp_flt_eval_method_iec_559): New.
(cpp_iec_559_value): Call it.
(c_cpp_builtins): Modify logic for __LIBGCC_*_EXCESS_PRECISION__,
call c_flt_eval_method to set __FLT_EVAL_METHOD__ and
__FLT_EVAL_METHOD_TS_18661_3__.
gcc/testsuite/
* gcc.dg/fpermitted-flt-eval-methods_3.c: New.
* gcc.dg/fpermitted-flt-eval-methods_4.c: Likewise.
