- Subject: [RFA]dwarf reader: Avoid complaint on const type
GDB CVS compiled for Linux arm gave several dwarf complaints
when debugging itself that I tried to fix.
Here is a first fix:
It seem that some symbol directly come as
DW_TAG_const_type, I believe it was due to
typedef const struct reloc_howto_struct reloc_howto_type;
from bfd-in.h (or bfd-in2.h), but I did not recheck this
carefully.
The patch below fixes that complaint.
Tested on compiler farm machine gcc16, no regression found.
Is this correct?
Maybe there are other position where DW_TAG_const_type
and DW_TAG_volatile_type should be added...

* dwarf2read.c (process_die): Also allow DW_TAG_const_type
and DW_TAG_volatile_type.
(new_symbol): Likewise.
