------- Comment #3 from tromey at gcc dot gnu dot org 2010-07-21 15:19 -------
The ordinary cases work fine with svn trunk gcc.
However, member pointers still don't have all the info emitted.
Consider this test case:
struct S { int f; };
template<int S::*MP> struct T { };
T<&S::f> v;
For v's type, I just see:
<2><4f>: Abbrev Number: 6 (DW_TAG_template_value_param)
<50> DW_AT_name : MP
<53> DW_AT_type : <0x58>
That is, this parameter has no value.

a simple test case
I'm attaching "temargs.cc", a simple test case from the gdb test suite.
I compiled this with today's svn trunk gcc.
When I dump the resulting DWARF I see good results for Base<double, ...>:
<1><47>: Abbrev Number: 5 (DW_TAG_structure_type)
<48> DW_AT_name : (indirect string, offset: 0x43): Base<double,
23, (& a_global), &S::f>
<4c> DW_AT_byte_size : 1
<4d> DW_AT_decl_file : 1
<4e> DW_AT_decl_line : 29
<4f> DW_AT_sibling : <0xb4>
<2><53>: Abbrev Number: 6 (DW_TAG_template_type_param)
<54> DW_AT_name : T
<56> DW_AT_type : <0xb4>
[...]
But I don't see the right results for Base<long, ...>. It is missing
all the template parameters:
<1><d0>: Abbrev Number: 5 (DW_TAG_structure_type)
<d1> DW_AT_name : (indirect string, offset: 0x191): Base<long int,
47, (& a_global), &S::f>
<d5> DW_AT_byte_size : 1
<d6> DW_AT_decl_file : 1
<d7> DW_AT_decl_line : 29
<d8> DW_AT_sibling : <0x105>
<2><dc>: Abbrev Number: 16 (DW_TAG_structure_type)
<dd> DW_AT_name : (indirect string, offset: 0x157): Inner<float>
