32 -- This package contains definitions for initial sizes and growth increments
33 -- for the various dynamic arrays used for the main compiler data structures.
34 -- The indicated initial size is allocated for the start of each file, and
35 -- the increment factor is a percentage used to increase the table size when
36 -- it needs expanding (e.g. a value of 100 = 100% increase = double)
38 -- Note: the initial values here are multiplied by Table_Factor as set by the
39 -- -gnatTnn switch. This variable is defined in Opt, as is the default value
40 -- for the table factor.
