23404 – gij trashes args of functions with more than 8 fp args (original) (raw)

Description Orion Poplawski 2005-08-15 17:27:24 UTC

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