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/parse.c | 13 +++++++++++++ 1 file changed, 13 insertions(+) (limited to 'gdb/parse.c') diff --git a/gdb/parse.c b/gdb/parse.c index 9303dfd..8841e59 100644 --- a/gdb/parse.c +++ b/gdb/parse.c @@ -248,6 +248,18 @@ write_exp_elt_dblcst (DOUBLEST expelt) } void +write_exp_elt_decfloatcst (gdb_byte expelt[16]) +{ + union exp_element tmp; + int index; + + for (index = 0; index < 16; index++) + tmp.decfloatconst[index] = expelt[index]; + + write_exp_elt (tmp); +} + +void write_exp_elt_type (struct type *expelt) { union exp_element tmp; @@ -718,6 +730,7 @@ operator_length_standard (struct expression *expr, int endpos, case OP_LONG: case OP_DOUBLE: + case OP_DECFLOAT: case OP_VAR_VALUE: oplen = 4; break; -- cgit v1.1
