CPU Architecture: VAX and Alpha
Version: v 6.2
Questions:
I'm trying to do a conversion of macro-32 code from
VAX (Open VMS 6.2 - Vax MACRO V5.4-3) to ALPHA
(Open VMS 6.2-1H3 - AMAC V2.1-17-267).
The source code is compiled (or assembled) on the
VAX successfully.
On the Alpha I have the following error :
%AMAC-E-ILLRELADR, (1) illegal relative addressing mode
-MACR
O-I-ATEXPLINE, at macro expansion line 89
The following is a portion of the listing which
contains the macro expansion :
X06/088 ?05F 0000004E .IIF IDN NEQ,EQL, BNEQ .+5
X06/089 ?05T 0000004E .IIF IDN NEQ,NEQ, BEQL .+5
X06/090 ?05F 00000050 .IIF IDN NEQ,GTR, BLEQ .+5
X06/091 ?05F 00000050 .IIF IDN NEQ,GEQ, BLSS .+5
X06/092 ?05F 00000050 .IIF IDN NEQ,LEQ, BGTR .+5
X06/093 ?05F 00000050 .IIF IDN NEQ,LSS, BGEQ .+5
X06/094 ?05F 00000050 .IIF IDN NEQ,GTRU, BLEQU .+5
X06/095 ?05F 00000050 .IIF IDN NEQ,GEQU, BLSSU .+5
X06/096 ?05F 00000050 .IIF IDN NEQ,LSSU, BGEQU .+5
If you look at this portion, I have more than one
relative addressing mode. Why the error occurs only
at line 089 ? Is it possible that the error message
is not correct ?
What should I do ?
Thank You

Please supply a small complete reproducer..

The listing indicates that inside the macro expansion at nested depth 6,
there is some nested (depth 5) conditional test that is only true at
relative line 89.. the other possibilities are all False and will not
be selected for further compilation.. it's unlikely that the error is
'not correct' but a reproducer should enable investigation of such a
possibility.

| 255.2 | Two questions, tqo answers | CPEEDY::FLEURY | | Mon Mar 10 1997 08:34 | 23 |
| re: .0
There are actually two issues here.
1) Why is the message only reported at line 89?
Close examination of the listing will show that line 89 is the only
line where the expansion is true. Only when the line is to be
processed will the compiler scan the line for syntax etc.
2) Why is the error reported at all?
From HELP/MESSAGE we find:
ILLRELADR, illegal relative addressing mode
Facility: AMAC, MACRO-32 Compiler for OpenVMS AXP
Explanation: A branch to a destination that is the offset from a
label (for example, BLSS FOO+2) is not allowed.
User Action: Place a label at the destination, and branch to that
label.

That entry arrived via the OpenVMS web site, short of contacting
the customer directly, it's not feasible to have a dialog...
I'll distill .2 and pass it along...

Well one wonders why we promote such a site if it's one-way traffic!

It's not an interactive site -- one has to use out-of-band methods
(direct e-mail, etc) to get more information on a problem. Various
questions and answers are batched-up, and are uploaded back to the
Wizards area of the web site.
