From f69fdf9bca80ac703890a51e124e408cbccbb743 Mon Sep 17 00:00:00 2001 From: Ulrich Weigand Date: Mon, 6 Nov 2017 15:56:35 +0100 Subject: Target FP: Add string routines to target-float.{c,h} This adds target_float_to_string and target_float_from_string, which dispatch to the corresponding floatformat_ or decimal_ routines. Existing users of those routines are changed to use the new target-float routines instead (most of those places already handle both binary and decimal FP). In addition, two other places are changes to use target_float_from_string: - define_symbol in stabsread.c, when parsing a floating-point literal from stabs debug info - gdbarch-selftest.c when initializing a target format values (to eliminate use of DOUBLEST there). gdb/ChangeLog: 2017-11-06 Ulrich Weigand * target-float.c (target_float_to_string): New function. (target_float_from_string): New function. * target-float.h (target_float_to_string): Add prototype. (target_float_from_string): Add prototype. * valprint.c: Include "target-float.h". Do not include "doublest.h" and "dfp.h". (print_floating): Use target_float_to_string. * printcmd.c: Include "target-float.h". Do not include "dfp.h". (printf_floating): Use target_float_to_string. * i387-tdep.c: Include "target-float.h". Do not include "doublest.h". (print_i387_value): Use target_float_to_string. * mips-tdep.c: Include "target-float.h". (mips_print_fp_register): Use target_float_to_string. * sh64-tdep.c: Include "target-float.h". (sh64_do_fp_register): Use target_float_to_string. * parse.c: Include "target-float.h". Do not include "doublest.h" and "dfp.h". (parse_float): Use target_float_from_string. * stabsread.c: Include "target-float.h". Do not include "doublest.h". (define_symbol): Use target_float_from_string. * gdbarch-selftests.c: Include "target-float.h". (register_to_value_test): Use target_float_from_string. --- gdb/stabsread.c | 10 +++------- 1 file changed, 3 insertions(+), 7 deletions(-) (limited to 'gdb/stabsread.c') diff --git a/gdb/stabsread.c b/gdb/stabsread.c index c51b3c7..830138b 100644 --- a/gdb/stabsread.c +++ b/gdb/stabsread.c @@ -41,7 +41,7 @@ #include "demangle.h" #include "gdb-demangle.h" #include "language.h" -#include "doublest.h" +#include "target-float.h" #include "cp-abi.h" #include "cp-support.h" #include @@ -798,19 +798,15 @@ define_symbol (CORE_ADDR valu, const char *string, int desc, int type, { case 'r': { - double d = atof (p); gdb_byte *dbl_valu; struct type *dbl_type; - /* FIXME-if-picky-about-floating-accuracy: Should be using - target arithmetic to get the value. real.c in GCC - probably has the necessary code. */ - dbl_type = objfile_type (objfile)->builtin_double; dbl_valu = (gdb_byte *) obstack_alloc (&objfile->objfile_obstack, TYPE_LENGTH (dbl_type)); - store_typed_floating (dbl_valu, dbl_type, d); + + target_float_from_string (dbl_valu, dbl_type, std::string (p)); SYMBOL_TYPE (sym) = dbl_type; SYMBOL_VALUE_BYTES (sym) = dbl_valu; -- cgit v1.1
