incorrect debug information with -O2 and above options

[M R Swami Reddy]

Hello Andrew,

Thanks for the reply.

OK. I will fill a PR for this issue.

And the test case is:
===
extern one();

main () { one(); }
===

I tried with all GCC 4.1.x and 4.2.x version. The same problem seen.

Btw, this issue is not seen with native (ie i386) gcc compiler.
Is there any macro definition missing for crx target port?


Thanks
Swami
