[Bug java/23404] New: Interpreted byte code does not run properly on ppc

[orion at cora dot nwra dot com]

This is on a Fedora Core 4 machine:

gij (GNU libgcj) version 4.0.1 20050727 (Red Hat 4.0.1-5)

The to be attached code does not run properly on ppc.  Runs fine on x86 (32 and
64 bit).  The byte-code appears to be correct because it runs fine using the IBM
JVM.

Compiled with:

javac plplot/*/*.java

Run with:

java plplot.examples.x08

The output is the arguments passed to plw3d().  In the source this is:

pls.w3d( 1.0, 1.0, 1.0, -1.5, 1.5, -0.5, 1.5, zmin, zmax,
                           alt[k], az[k] );

Output (first loop) is:

0.0
1.0
1.0
-1.5
1.5
-0.5
1.5
-5.093869927024149
NaN
-3.7431896459052014E-274
5.32506451E-315

Correct output should be:

1.0
1.0
1.0
-1.5
1.5
-0.5
1.5
-5.093869927024149
6.636602508481567
60.0
30.0

It looks like arg1, arg9, arg10, and arg11 are not passed properly.

I think this is a libffi issue rather than anything else.

I could not reproduce this problem using a powerpc64 gij.  However, I could when
using a powerpc gij.  Retargetting.
