Hi,
following patch fixes the behavior of g++ for arm.
It is against the gcc-3_0-branch.
The difference can be seen by comparing following testresults :
before :
<http://gcc.gnu.org/ml/gcc-testresults/2002-02/msg00075.html>
after :
<http://gcc.gnu.org/ml/gcc-testresults/2002-02/msg00102.html>
This should also resolve the problem of compiling a
simple 'hello world' c++ program.
IMHO, this patch is definitely needed for gcc-3.0.4 !
Greetings,
