1.4.8.7. Type Entry
The type field in the symbol table entry contains information on the basic and
derived type for the symbol. The type information is generated for a symbol only
if the files are generated with symbolic debugging in mind. Type information is
generated when the compiler is invoked with the
-q
or
-q1
flag and/or the
assembler is invoked with the
-L
flag and
.type
directives are inserted into the
assembly language file. Each symbol has one basic or fundamental type and
from zero to six derived types. The following is the format of the 16-bit type entry:
d6 d5 d4 d3 d2 d1 type
Bits 0 through 3, identified as
type
, indicate one of the fundamental types listed
in Table 1.22. Bits 4 through 15 are arranged as six 2-bit fields identified as
d1
through
d6
. The fields
d1
through
d6
represent levels of the derived types listed
in Table 1.23.
