In O1 mode some of the functions are optimized out and it is impossible to call them.
In case of deque and queue (which is build over deque) it is a bummer for the size() method is calculated.
After finding some examples on the Internet we found nothing usable (I guess because our gcc was using different deque memory structure.)
So we created a new version.
pdequeue_info variable
- Shows size, first, and last element
pdequeue variable [firstidx [lastidx]]
- Shows contents or a range.
define pdequeue_info
set $var=($arg0)
set $sizeof=sizeof( **$var._M_impl._M_start._M_node )
set $size=$sizeof < 512 ? ( 512 / $sizeof ) : 1
set $i=0
while $i < $var._M_impl._M_map_size && $var._M_impl._M_map[ $i ] == 0
set $i++
end
set $rv = 0
while $i < $var._M_impl._M_map_size && $var._M_impl._M_map[ $i ] != $var._M_impl._M_finish._M_first
set $rv += $size
set $i++
end
if $var._M_impl._M_map[ $i ] != 0
set $rv += $var._M_impl._M_finish._M_cur - $var._M_impl._M_finish._M_first
end
printf "size : "
p $rv
if $rv > 0
printf "first : "
p *$var._M_impl._M_start._M_cur
if $rv > 1
printf "last : "
p *( $var._M_impl._M_finish._M_cur - 1 )
end
end
end
define __pdeque_show_group
set $cur=($arg0)
set $size=($arg1)
set $f=($arg2)
set $l=($arg3)
set $j=0
while $j < $size && $n <= $l
if $n >= $f
printf "[%i] : ", $n
p *$cur
end
set $cur++
set $j++
set $n++
end
end
define pdequeue
set $var=($arg0)
set $f=-1
set $l=9999999999
if $argc == 2
set $f=($arg1)
set $l=$f
end
if $argc == 3
set $f=($arg1)
set $l=($arg2)
end
set $sizeof=sizeof( **$var._M_impl._M_start._M_node )
set $size=$sizeof < 512 ? ( 512 / $sizeof ) : 1
set $i=0
while $i < $var._M_impl._M_map_size && $var._M_impl._M_map[ $i ] == 0

end
set $n=0

end
