gcc/ * real.c, real.h: Rewrite from scratch. * Makefile.in (simplify-rtx.o): Depend on TREE_H. (paranoia): New target. * builtins.c (fold_builtin_inf): Use new real.h interface. * c-common.c (builtin_define_with_hex_fp_value): Likewise. * c-lex.c (interpret_float): Likewise. * emit-rtl.c (gen_lowpart_common): Likewise. * optabs.c (expand_float): Use real_2expN. * config/ia64/ia64.md (divsi3, udivsi3): Likewise. * defaults.h (INTEL_EXTENDED_IEEE_FORMAT): New. (FLOAT_WORDS_BIG_ENDIAN): New. * cse.c (find_comparison_args): Don't pass FLOAT_STORE_FLAG_VALUE directly to REAL_VALUE_NEGATIVE. * loop.c (canonicalize_condition): Likewise. * simplify-rtx.c: Include tree.h. (simplify_unary_operation): Don't handle FIX and UNSIGNED_FIX with floating-point result modes. * toplev.c (backend_init): Call init_real_once. * fold-const.c (force_fit_type): Don't call CHECK_FLOAT_VALUE. * tree.c (build_real): Likewise. * config/alpha/alpha.c, config/vax/vax.c (float_strings, float_values, inited_float_values, check_float_value): Remove. * config/alpha/alpha.h, config/m68hc11/m68hc11.h, config/m88k/m88k.h, config/vax/vax.h (CHECK_FLOAT_VALUE): Remove. * doc/tm.texi (CHECK_FLOAT_VALUE): Remove. gcc/f/ * target.c (ffetarget_real1): Don't pass FFETARGET_ATOF_ directly to ffetarget_make_real1. (ffetarget_real2): Similarly. * target.h (ffetarget_cvt_r1_to_rv_, ffetarget_cvt_rv_to_r2_, ffetarget_cvt_r2_to_rv_): Use new real.h interface and simplify. gcc/java/ * jcf-parse.c (get_constant): Runtime check for IEEE format; use new real.h interface. * jcf-write.c (find_constant_index): Use new real.h interface. * lex.c (IS_ZERO): Use REAL_VALUES_EQUAL. contrib/ * paranoia.cc: New file.
