             Bug #: 14760
           Summary: gdb.cp/temargs.exp regression with FSF GCC HEAD
           Product: gdb
           Version: HEAD
            Status: NEW
          Severity: normal
          Priority: P2
         Component: c++
        AssignedTo: unassigned@sourceware.org
        ReportedBy: jan.kratochvil@redhat.com
    Classification: Unclassified
            Target: x86_64-unknown-linux-gnu


FAIL: gdb.cp/temargs.exp: test type of T in inner_m
FAIL: gdb.cp/temargs.exp: test value of I in inner_m
FAIL: gdb.cp/temargs.exp: test value of P in inner_m
FAIL: gdb.cp/temargs.exp: test value of MP in inner_m

ptype T
No symbol "T" in current context.
(gdb) FAIL: gdb.cp/temargs.exp: test type of T in inner_m
print I
No symbol "I" in current context.
(gdb) FAIL: gdb.cp/temargs.exp: test value of I in inner_m
print P == &a_global
No symbol "P" in current context.
(gdb) FAIL: gdb.cp/temargs.exp: test value of P in inner_m
print MP
No symbol "MP" in current context.
(gdb) FAIL: gdb.cp/temargs.exp: test value of MP in inner_m

I do not see if it is a GCC or GDB bug.

--- Comment #1 from Tom Tromey <tromey at redhat dot com> 2012-10-24 15:33:51 UTC ---
The difference is in the DWARF for the class Base.

GCC master emits:

 <1><f1>: Abbrev Number: 15 (DW_TAG_structure_type)
    <f2>   DW_AT_name        : (indirect string, offset: 0x191): Base<long int,
47, (& a_global), &S::f>    
    <f6>   DW_AT_byte_size   : 1    
    <f7>   DW_AT_decl_file   : 1    
    <f8>   DW_AT_decl_line   : 30    
    <f9>   DW_AT_declaration : 1    
    <f9>   DW_AT_sibling     : <0x155>    

The DW_AT_declaration causes gdb to ignore it.
However there is no concrete definition for the type.

I tend to think this is a gcc regression.
