Subject: kaffe: Builds broken package with gcc-4.3

Date: Mon, 25 Feb 2008 15:57:26 -0500

Package: kaffe
Version: 2:1.1.8-3
Severity: important
User: tbm@cyrius.com
Usertags: ftbfs-gcc-4.3

When I build kaffe in a pbuilder chroot with gcc -> gcc-4.3, the build 
succeeds but with some test failures:

FAIL: FileTest.java
FAIL: InterfaceSuperClass.java
FAIL: ImplementClass.java
FAIL: FieldErrors.java
FAIL: MethodErrors.java

The resulting binary also fails to build several other packages, which I 
erroneously reported as bugs against those packages.  See #467381, #467383, 
#467384 for details.

Rebuilding with gcc -> gcc-4.2, those problems go away.

I'm on the way of packaging a new kaffe upstream version. I will check
of this wokrs with it but this will take some time. Currently it doesn't
build at all and I need to find out why.

Subject: Investigations about failure

Date: Thu, 10 Apr 2008 10:06:20 +0200

gcc-4.2 and gcc-4.3 differ in the representation of char values: gcc-4.2
represents a char as a 32 bit value (bits 0..7 is the char value; bits
8..31 are always set to zero); gcc-4.3 uses only the lower 8 bits,
ignoring bits 8..31.

kaffe defines "typedef unsigned char jboolean;" in
kaffe-1.1.8/libraries/javalib/external/classpath/include/jni_md-x86-linux-gnu.h
but assumes %eax is 0/1 in compiled Java code. This makes compiled Java
code calling into native C code almost always assume "true" for jboolean
return values due to the non-zero "garbage" in bits 8..31.


Compiling the following source demonstrates the issue: compiled with
gcc-4.2, the return value in %eax always is either 0 or 1. Compiled with
gcc-4.3, only %al is set ot 0 or 1; the remaining bits 8..31 of %eax
remain unset.

Can you take a look into kaffe 1.1.9 (not packaged yet due to different
problems) if that is fixed? I haven't found the time yet for this)

Hi

Can we expect an upload shortly to fix this bug? It looks like building
with gcc-4.2 is the safest option?

Cheers

Luk

We can always hope for an upload. In particular, the FileTest.java
test results when compiling with gcc vs. gcc-4.2 seem to match the
description very well.
Test success is strictly increasing here and as noone else seems to
want to take a shot I'm uploading the following NMU.

Kind regards

T.
