src/gdb ChangeLog target-descriptions.c testsu ...


CVSROOT:	/cvs/src
Module name:	src
Changes by:	wtedeschi@sourceware.org	2013-04-30 12:33:52

Modified files:
	gdb            : ChangeLog target-descriptions.c 
	gdb/testsuite  : ChangeLog 
Added files:
	gdb/testsuite/gdb.xml: maint_print_struct.exp 
	                       maint_print_struct.xml 

Log message:
	Fix display of structures/bitfields in register description.
	
	Add support for displaying structures and bitfields for registers when
	executing "maint print c-tdesc". This command is also used when
	converting the xml target description file into c file.
	
	Example of the behaviour is given below reporting a snipet of the xml file
	and a snippet of the c code generated.
	
	XML file contains:
	...
	<union id="vecint">
	<field name="v4" type="v4int8"/>
	<field name="v2" type="v2int16"/>
	</union>
	
	<struct id="struct1">
	<field name="v4" type="v4int8"/>
	<field name="v2" type="v2int16"/>
	</struct>
	
	<struct id="struct2" size="8">
	<field name="f1" start="0" end="34"/>
	<field name="f2" start="63" end="63"/>
	</struct>
	...
	
	Setting this xml file as target description file and
	issuing the maintenance print c-tdesc the following output
	is obtained:
	
	feature = tdesc_create_feature (result, "extra");
	field_type = tdesc_named_type (feature, "int8");
	tdesc_create_vector (feature, "v4int8", field_type, 4);
	
	field_type = tdesc_named_type (feature, "int16");
	tdesc_create_vector (feature, "v2int16", field_type, 2);
	
	type = tdesc_create_union (feature, "vecint");
	field_type = tdesc_named_type (feature, "v4int8");
	tdesc_add_field (type, "v4", field_type);
	field_type = tdesc_named_type (feature, "v2int16");
	tdesc_add_field (type, "v2", field_type);
	
	C output is not supported type "struct1".
	
	This is finally the issue.

	* target-descriptions.c (maint_print_c_tdesc_cmd):
	Add case to parse structures as register types and
	bitfields.
