Hi,
one such a longstanding pain - accessing pretty-printed field name does not
work:
(gdb) p *type.main_type
$2 =
{name = 0x0,
[...]
field[0]:
########
{name = 0x2115978 "i",
[...]
bitpos = 0},
cplus_stuff = 0xf33b80}
(gdb) p/r *type.main_type
$3 = {code = TYPE_CODE_STRUCT, [...]
target_type = 0x0, flds_bnds = {fields = 0x21161f0, bounds = 0x21161f0},
####################################################
[...], func_stuff = 0xf33b80}}
(gdb) p type.main_type.field[0]
########
There is no member named field.
###############################
(gdb) p type.main_type.fields[0]
#########
There is no member named fields.
################################
(gdb) p type.main_type.flds_bnds.fields[0]
###################
$3 = {loc = {bitpos = 0, physaddr = 0, [...], name = 0x2115978 "i"}
Probably clear to check it in. I had to `print/r' to suppress gdb-gdb.py to
ba able to access GDB types fields.
Thanks,
Jan
