-- definition of the system implementation parameters to ensure

-- that the value of these parameters is available for analysis
|

-- of the declarations here (using Rtsfind at compile time).

-- The underlying priorities table provides a generalized mechanism
|

-- for mapping from Ada priorities to system priorities. In some

-- cases a 1-1 mapping is not the convenient or optimal choice.

|
||||
-- For DEC Threads OpenVMS, we use the full range of 31 priorities
|
||||
-- in the Ada model, but map them by compression onto the more limited
|
||||
-- range of priorities available in OpenVMS.
|
||||
|
||||
-- To replace the default values of the Underlying_Priorities mapping,
|
||||
-- copy this source file into your build directory, edit the file to
|
||||
-- reflect your desired behavior, and recompile with the command:
|
||||
|
||||
-- $ gcc -c -O3 -gnatpgn system.ads
|
||||

|
||||
|
||||
-- $ gnatmake -a -gnatn -O3 <your application>
|
