The /inline_depth and /ipa_depth
qualifiers set the maximum level of subprogram nesting that KAP
will attempt to inline. Higher values instruct KAP to trace CALLs
and function references further. The values and their meanings are
as follows:
1 - 10 - Inline routines to this depth.
0 - Use the default value.
-1 - Inline only routines that do not contain
subroutin or function references.
The C*$* [no]inline and C*$* [no]ipa
directives, when enabled, are not affected by the
/inline_depth or /ipa_depth
restrictions.
