From 27bc4d809ea2b4a3e4833806494db3a2fee83c64 Mon Sep 17 00:00:00 2001 From: Thiago Jung Bauermann Date: Thu, 25 Oct 2007 18:01:58 +0000 Subject: 2007-10-25 Wu Zhou Thiago Jung Bauermann * c-exp.y (YYSTYPE): Add typed_val_decfloat for decimal floating point in YYSTYPE union. (DECFLOAT) Add token and expression element handling code. (parse_number): Parse DFP constants, which end with suffix 'df', 'dd' or 'dl'. Return DECFLOAT. * eval.c (evaluate_subexp_standard): Call value_from_decfloat to handle OP_DECFLOAT. * expression.h (enum exp_opcode): Add an opcode (OP_DECFLOAT) for DFP constants. (union exp_element): Add decfloatconst to represent DFP elements, which is 16 bytes by default. * parse.c (write_exp_elt_decfloatcst): New function to write a decimal float const into the expression. (operator_length_standard): Set operator length for OP_DECFLOAT to 4. * parser-defs.h (write_exp_elt_decfloatcst): Prototype. * valarith.c (value_neg): Add code to handle the negation operation of DFP values. * value.c (value_from_decfloat): New function to get the value from a decimal floating point. * value.h (value_from_decfloat): Prototype. --- gdb/eval.c | 5 +++++ 1 file changed, 5 insertions(+) (limited to 'gdb/eval.c') diff --git a/gdb/eval.c b/gdb/eval.c index ee1ac58..2e6a832 100644 --- a/gdb/eval.c +++ b/gdb/eval.c @@ -456,6 +456,11 @@ evaluate_subexp_standard (struct type *expect_type, return value_from_double (exp->elts[pc + 1].type, exp->elts[pc + 2].doubleconst); + case OP_DECFLOAT: + (*pos) += 3; + return value_from_decfloat (expect_type, exp->elts[pc + 1].type, + exp->elts[pc + 2].decfloatconst); + case OP_VAR_VALUE: (*pos) += 3; if (noside == EVAL_SKIP) -- cgit v1.1
