[PATCH] Set correct source location for deallocator calls

Tue Sep 4 20:32:00 GMT 2012

Looks like even with addr2line properly installed, the gcj generated
code cannot get the correct source file/lineno. Do I need to pass in
anything to gcj to let it know where addr2line is?
Thanks,
Dehao

The java code is shown below:
stacktrace.java
/* This test should test the stacktrace functionality.
 We only print ClassName and MethName since the other information
 like FileName and LineNumber are not consistent while building
 native or interpreted and we want to test the output inside the dejagnu
 test environment.
 Also, we have to make the methods public since they might be optimized away
 with inline's and then the -O3/-O2 execution might fail.
