From 3fcf899da106890f3948093c2424f9dff67d6fe0 Mon Sep 17 00:00:00 2001 From: Artemiy Volkov Date: Mon, 20 Mar 2017 13:47:52 -0700 Subject: Support rvalue references in the gdb python module (includes doc/) This patch adds the ability to inspect rvalue reference types and values using the gdb python module. This is achieved by creating two wrappers for valpy_reference_value(), using the ReferenceExplorer class to handle the objects of rvalue reference types and placing necessary checks for a TYPE_CODE_RVALUE_REF type code next to the checks for a TYPE_CODE_REF type code. gdb/ChangeLog PR gdb/14441 * doc/python.texi (Types in Python): Add TYPE_CODE_RVALUE_REF to table of constants. * python/lib/gdb/command/explore.py: Support exploring values of rvalue reference types. * python/lib/gdb/types.py: Implement get_basic_type() for rvalue reference types. * python/py-type.c (pyty_codes) : New constant. * python/py-value.c (valpy_getitem): Add an rvalue reference check. (valpy_reference_value): Add new parameter "refcode". (valpy_lvalue_reference_value, valpy_rvalue_reference_value): New wrappers for valpy_reference_value(). * python/py-xmethods.c (gdbpy_get_xmethod_result_type) (gdbpy_invoke_xmethod): Likewise. --- gdb/python/py-xmethods.c | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-) (limited to 'gdb/python/py-xmethods.c') diff --git a/gdb/python/py-xmethods.c b/gdb/python/py-xmethods.c index d01488f..e061da2 100644 --- a/gdb/python/py-xmethods.c +++ b/gdb/python/py-xmethods.c @@ -464,9 +464,10 @@ gdbpy_get_xmethod_result_type (const struct extension_language_defn *extlang, if (!types_equal (obj_type, this_ptr)) obj = value_cast (this_ptr, obj); } - else if (TYPE_CODE (obj_type) == TYPE_CODE_REF) + else if (TYPE_IS_REFERENCE (obj_type)) { - struct type *this_ref = lookup_lvalue_reference_type (this_type); + struct type *this_ref + = lookup_reference_type (this_type, TYPE_CODE (obj_type)); if (!types_equal (obj_type, this_ref)) obj = value_cast (this_ref, obj); -- cgit v1.1
