Hello, I'm working on a project for which a MN103 compiler is needed. We currently use Matsushita's standard compiler, which in turn is gcc 3.2.2 patched and corrected by RedHat. This one works well, but the corrections seem to have never been released to the open source community. So, in order to get rid of this compiler (which is furthermore very expensive) I am looking for a free GCC compiler for MN103 (i.e. one directly provided by GNU) and I have tested GCC 3.3.2 and GCC 3.4.5 for MN103 (cross compiler). Unfortunately, those compilers seem not to work correctly when used with optimization enabled (-O2). I cannot give a lot of information on this bug, except that our test suites crash when -O2 optimizations are activated (but not with Matsushita's GCC compiler). The bug is not so frequent and seem to happen especially when a lot of context switches occur (in multithreaded stress tests). So, my question is : do you have any information about a potential bug related to optimization in GCC's MN103 port ? Can you give me some advice ? Also, I think RedHat should have contributed back to the open source community by giving their corrections and patches to the FSF. Am I right ? Best regards,
