## print-type-counts

Arguments: &optional location

Prints a list of quantities and sizes of lisp objects in the specified location in the heap, along with type names and type codes of each object type printed. The list is printed in sorted order starting with the object type with the most bytes in the specified location. Percentages are also printed; these are percentages of the total of the specified location. location is interpreted as follows:

`location` | Meaning
`:new` | Print information on objects in newspace
`:pan` | Print information on panified objects (see below)
`:notpan` | Print information on non-panified objects in newspace (see below)
`:old` | Print information on objects in oldspace, i.e. tenured objects
`:malloc` | Print information about the malloc arena.
`:holes` | Print information about the types and sizes of the objects that were removed on the most recent global-gc. Note that no output is available until the first global-gc is done. See the example below.
`t` | Print information on all objects. This is the default.

A panified object (from Peter Pan, who never grew up) has a bit set that prevents it from being tenured. Only the system can set this bit. Note that malloc space, stack space, and purespace are not considered to be the heap.

### Examples

Here is an example of the information printed when location is `:holes`. Note that no information is printed until the first global garbage collection is done (a global gc is triggered by a call to gc with argument `t`). The output you see will likely be different, of course.

    cl-user(1): (print-type-counts :holes)
    code   type                                 items     bytes

     total bytes = 0
    cl-user(2): (gc t)
    cl-user(3): (print-type-counts :holes)
    code   type                                 items     bytes
     96: (simple-array t)                           33      4656 34.3%
    101: (simple-array character)                   77      2888 21.3%
    100: (simple-array (unsigned-byte 32))           1      2504 18.5%
      1: cons                                      304      2432 17.9%
     15: structure                                  21       840  6.2%
      9: closure                                     7       112  0.8%
     18: bignum                                      9        88  0.6%
      7: symbol                                      1        24  0.2%
     11: readtable                                   1        16  0.1%

     total bytes = 13560
    cl-user(4):
