PowerAdaÆ 5.8b Release Notes
Mar. 4, 2015
These Release Notes contain information relevant to Version 5.8b of the
OCS PowerAda Compilation System, supplementing the PowerAda User's Guide:
http://www.ocsystems.com/user_guide/powerada
1. Introduction
Version 5.8b of the PowerAda Compilation System is a bug-fix and feature
update of the PowerAda development tools from OC Systems.
2. Getting Help
If you have any comments, would like additional information, need a
different media format, or you have any other installation or
configuration problems, please contact OC Systems by internet at
support@ocsystems.com or by telephone at (703)-359-8160.
3. Requirements
System Requirements for each of the PowerAda hosts are:
For PowerAda/AIX: any computer running AIX version 5.3 or later
For PowerAda/Linux: any modern Intel Pentium-based computer running
Red Hat Linux 8 or later (with a version 2.4.18 kernel or later)
Contact OC Systems for help installing PowerAda on versions or platforms
other than these.
The file "README" contains more detailed notes on requirements and
installation. Please refer to it before installing PowerAda on any
supported host. Typically, 700 MB of disk space are required for
installation of PowerAda on any of the host platforms.
4. Licensing
PowerAda 5.8b works with the software product FLEXlm. See the PowerAda
Installation Guide for more information about setting up the license
manager.
PowerAda 5.8b for AIX does not require a new license if you already have a
valid license for PowerAda 4.1 (or newer) for AIX. PowerAda 5.8b for Linux
does not require a new license if you already have a valid license for
PowerAda 5.3 (or newer) for Linux. Replacements for older licenses can be
reissued by support@ocsystems.com. The license keys for AIX are different
from those for Linux, as the products are sold separately.
5. Compatibility
No compabitility issues were introduced in PowerAda 5.8b relative to 5.8.
PowerAda 5.8 for AIX introduced a slightly different layout within the
subprogram call stack frames at runtime, to comply with the IBM published
standard Application Binary Interface. The ABI required each frame's
Register Save Area (RSA) to be minimal size, and omitted if unused, so the
formerly fixed sized RSA became varying in size. In effect, the GPR RSA
was shifted down to where the FPR RSA once was within that frame. The
subprogram body's instructions were NOT changed, but the body's prologue
and epilogue instructions that automatically save and restore non-volatile
registers (per ABI standard function calling conventions) will necessarily
use slightly different offsets within the stack frame. This change did
not apply to PowerAda 5.8 for Linux on IA32.
PowerAda 5.7d1 changed some non-native T'Bit_Order representation clauses.
New Ada rules for a record representation clause of non-native T'Bit_Order
endianness were clarified by AI95-00133, and implemented in PowerAda 5.7d1.
There's no change when native Bit_Order (i.e., default endianness) applies.
These new rules in RM95 13.5 Record Layout changed the semantic meaning and
legality of values within a Component_Clause and its associated attributes
R.C'Position, R.C'First_Bit, and R.C'Last_Bit. The new Ada language rules
now give users a way to write a single common record layout representation
clause that works for both Big-Endian and Little-Endian machines, to
enhance portability. For backwards compatibility, PowerAda also allows a
representation clause to specify a non-native layout that's smaller than a
typical machine scalar, without forcing it up to the next larger size.
Otherwise, PowerAda 5.8b version is source-code compatible with prior
PowerAda versions up to 5.2. This only means that a complete recompilation
of your source code is required.
PowerAda AIX 5.8b object code is NOT compatible with that produced by
versions *prior to 5.8*.
Projects created by versions prior to PowerAda 5.8 cannot be opened using
PowerAda 5.8b. If you are sure you know what you're doing, you can get
around this by doing the following
cd adaproj # or whatever is your project root directory
rm .adaproj # delete the current project state file
aprojinit -k # create a new project state file, keeping the directory
Note that this and future versions of PowerAda will support AIX 5.3 and newer.
OC Systems can provide PowerAda 5.8b for AIX 5.2, upon request.
PowerAda 5.2 will continue to be supported as the LegacyAda version of
PowerAda for use on older AIX 4 operating systems.

7. Limitations and Unimplemented Features
If you encounter any problem, or have any suggestions for improvement
or enhancement, please contact OC Systems at support@ocsystems.com.
We can't fix what we don't know about.
See APPENDIX C, "Implementation Characteristics" (corresponding to
Annex M of the Ada95 Reference Manual) for a detailed description
of which optional portions of the language have been implemented.
PowerAda/Linux does not do any stack overflow checking, and so it will
dump core on insufficient stack space rather than raise STORAGE_ERROR.
The user should make sure that all task stacks are given sufficient
storage to execute.
