Bug #: 14762
Summary: Debug info for anonymous structs with linkage names
Product: clang
Version: unspecified
Platform: PC
OS/Version: All
Status: NEW
Keywords: googler
Severity: enhancement
Priority: P
Component: C++
AssignedTo: [email protected]
ReportedBy: [email protected]
CC: [email protected], [email protected]
Blocks: 14330
Classification: Unclassified
The debug info for types such as:
typedef struct { foo f; } bar;
in Clang does not include the name 'bar' in any of the debug info for the
anonymous struct. GCC includes the MIPS_linkage_name for the anonymous struct
as '3bar' as well as emitting the DW_AT_name of the ctor and dtor as "bar" and
"~bar" respectively.
The latter (emitting the name of the ctor and dtor as bar/~bar) seems to be a
bug ( http://gcc.gnu.org/bugzilla/show_bug.cgi?id=47510 ) & instead should just
be emitted as the linkage name, possibly (though I don't know if that'll
resolve the test case).
This was found in the GDB 7.5 test suite (gdb.cp/anon-struct.exp).
