Do any of the gcc java developers have access to intel darwin?
We are seeing segfaults on i686-apple-darwin9/10 and x86_64-apple-darwin9/10
when compiling code like...
public class testme {
public static void main(String args[]){
System.out.println("Hello");
}
}
with "gcj --main=testme -O testme.java" which produces segfaults of the
form...
gcj: Internal error: Abort trap (program ecj1)
Please submit a full bug report.
See <http://gcc.gnu.org/bugs.html> for instructions.
This failure is showing up on x86_64-apple-darwin9/10 for gcc 4.4.2
and gcc trunk. Interestingly, i686-apple-darwin9 doesn't show the
segfault for gcc 4.4.2 but does for gcc trunk. Both gcc 4.4.2 and
gcc trunk show the segfault for i686-apple-darwin10. The gcc compiler
with ftp://sourceware.org/pub/java/ecj-latest.jar in the top level
of the build directory to produce the ecj1 binary. The gcc configurations
are of the form...
../gcc-4.5-20091107/configure --prefix=/sw --prefix=/sw/lib/gcc4.5
--mandir=/sw/share/man --infodir=/sw/share/info

--build=i686-apple-darwin9 --host=i686-apple-darwin9
--target=i686-apple-darwin9
This issue has been filed as PR41991.

ps Using -v to figure out how ecj1 is called, I obtained the following backtrace
under gcc trunk...

This is caused by incorrect unwind information being generated by gcc, or
by a bug in gcc's unwinder library.

Andrew,
Shouldn't the libjava testsuite contain some rudimentary tests using gcj
to make sure it is functional? The recent testsuite results don't suggest
major problems with java on intel darwin...

This means that, whatever the cause of the bug, it wasn't present
when these tests were run.
You can easily verify that yourself by running 'make check-target-libjava'.

Andrew,
What exactly would I need to add to...
public class testme {
public static void main(String args[]){
System.out.println("Hello");
}
}
to convert it into a libjava compilation/execution test case for gcj?
It might be simplier to just try to run such a test case from within
the libjava dejagnu harness to verify that the issue doesn't exist
within it. I was considering something like...
gcj --main=testme -O pr41991.java
for the compilation and a scan for Hello on the output of the
execution run. Thanks in advance for any hints on where to place
such a test within the libjava dejagnu tests and what header
entries to add.

you need to add one file, testme.out, which contains the expected
output from testme. Put both files in libjava/testsuite/libjava.lang.

I find it very hard to believe that the rest of the tests would pass
while Hello, world fails.

Do you mean something like libjava.lang/Array_3?

Andrew,
Actually the nature of the testsuite will mask this failure on intel darwin.
The gcj compiler doesn't segfault when presented with a *.class file to compile
into an executable. Only when presented a *.java file will the gcj compiler abort.
The output to libjava.log suggests that all of the tests in libjava.lang are executed
via the class file contained in the associated jar file rather than compiling directly
the java file itself.

I suspect if the libjava harness was fixed to compile the java files if a ecj1 was

In that case, gcj isn't aborting. gcj only ever compiles .class -> .o, where
.java -> .class compilation is performed by ecj1.

Andreas Tobler Seems to think it's to do with stack execution, but
I can't understand how that can be: gcj doesn't generate executable
code on the stack.

That is what I told you, Andrew, on #irc.

Gcj not, but what is with ecj1? The suggestion I posted to the PR
affects the ecjx linking.
The patchlet I posted in the 41991 PR does allow me to compile a java
file into a class file and execute it with gij. Also the same for java
to binary compile. This was not the case before. I went back to Jan 31
09 and I always got an Abort with ecj1.
Note beside, I always installed the built gcc and tested the installed
binaries.

Andreas,
I'll try the proposed patch under x86_64-apple-darwin9 this weekend.
It wouldn't be a huge surprise if it worked as darwin10 has subsumed
libgcc into libSystem. Thus under darwin10, the system unwinder is
always in use (rather that the one in FSF libgcc as is the case under darwin9).
