2002-03-31* libgcc2.c (__bb_exit_func): Make static.Richard Henderson1-1/+1
From-SVN: r51647
2002-03-25toplev.c: Don't include setjmp.h.Zack Weinberg1-4/+1
* toplev.c: Don't include setjmp.h. Kill float_handler_set, float_handled, float_handler, float_signal, set_float_handler, and do_float_handler. Set handler for SIGFPE to crash_signal. * toplev.h: Don't prototype do_float_handler. * c-lex.c: Fold parse_float into lex_number. Make warning about portability of hex float constants more informative, and don't issue it on top of a syntax error. * fold-const.c: Fold const_binop_1 and fold_convert_1 into their callers. * real.h: Define REAL_VALUE_ABS here... * simplify-rtx.c: ... not here. Fold check_fold_consts, simplify_unary_real, simplify_binary_real, and simplify_binary_is2orm1 into their callers. * tree.c: Fold build_real_from_int_cst_1 into caller. * doc/tm.texi: Document REAL_VALUE_ABS and REAL_VALUE_NEGATIVE. * tsystem.h: Include float.h here... * libgcc2.c: ... not here. java: * lex.c: Change java_perform_atof to take normal parameters instead of a pointer to a parameter block. Call it directly from java_lex. testsuite: * gcc.dg/c90-hexfloat-1.c: Adjust error regexps. From-SVN: r51336
2002-03-23real.h: Don't define REAL_INFINITY or REAL_IS_NOT_DOUBLE.Zack Weinberg1-26/+4
* real.h: Don't define REAL_INFINITY or REAL_IS_NOT_DOUBLE. Always make REAL_VALUE_TYPE a struct containing an array of HOST_WIDE_INT, not a double. Tidy up the code deciding how big it is. Don't declare or use union real_extract. * emit-rtl.c (init_emit_once), varasm.c (immed_real_const_1, decode_rtx_const, output_constant_pool), config/a29k/a29k.c (print_operand), config/arm/arm.c (output_move_double), config/arm/arm.md (consttable_4, consttable_8), config/romp/romp.c (output_fpops), config/s390/s390.h (ASM_OUTPUT_SPECIAL_POOL_ENTRY), config/xtensa/xtensa.c (xtensa_output_literal): Don't use union real_extract. * config/dsp16xx/dsp16xx.c (print_operand), config/i860/i860.c (sfmode_constant_to_ulong), config/ns32k/merlin.h (PRINT_OPERAND), config/ns32k/ns32k.c (print_operand), config/pdp11/pdp11.h (PRINT_OPERAND), config/we32k/we32k.h (PRINT_OPERAND): Don't use local version of union real_extract. * config/convex/convex.c (check_float_value), config/vax/vax.c (vax_float_literal), config/m88k/m88k.md (divdf3), config/dsp16xx/dsp16xx.md (fixuns_trunchfhi2), config/pdp11/pdp11.c (output_move_quad): Don't do host arithmetic on target floating point quantities. * config/a29k/a29k.md, config/dsp16xx/dsp16xx.c (output_dsp16xx_float_const): Don't test HOST_FLOAT_FORMAT. * fold-const.c (fold), simplify-rtx.c (simplify_binary_real): Use MODE_HAS_INFINITIES rather than #ifdef REAL_INFINITY. * real.c (earith): Test INFINITY rather than REAL_INFINITY; NANS implies INFINITY, so can drop #ifdef NANS inside #ifndef INFINITY. * print-rtl.c (print_rtx): Disable code which needs floating-point emulator. * libgcc2.c: Include float.h and use DBL_MANT_DIG, FLT_MANT_DIG, to define DF_SIZE and SF_SIZE, rather than depending on HOST_FLOAT_FORMAT to be defined properly. * ch/grant.c, cp/error.c: Always use REAL_VALUE_TO_DECIMAL; don't test REAL_IS_NOT_DOUBLE. * config/1750a/1750a.c (get_double, float_label): Delete. (print_operand): Delete huge commented-out chunk. Use REAL_VALUE_TO_DECIMAL. * config/1750a/1750a-protos.h: Delete prototypes of deleted functions. * config/convex/convex.h: Always set TARGET_FLOAT_FORMAT to IEEE_FLOAT_FORMAT. * config/i370/i370.h (PRINT_OPERAND [TARGET_HLASM version]): Use REAL_VALUE_TO_DECIMAL as ELF version does. * config/m88k/m88k.c (real_power_of_2_operand, legitimize_operand): Take the REAL_VALUE_TYPE and/or union real_extract out of the union; run the input through REAL_VALUE_TO_TARGET_DOUBLE, then plug the pair of longwords from that into the union. * config/pdp11/pdp11.c (output_move_double): Rearrange parentheses to make automatic indenter happy. * doc/tm.texi (Cross-compilation): Rename node to "Floating Point" and rewrite to describe current situation. Also adjust documentation of REAL_VALUE_TO_TARGET_SINGLE and friends to match code. * doc/rtl.texi: Adjust cross reference. From-SVN: r51210
