Hello all,
I have a question before I post a patch.
Gas on MIPS|Alpha targets, symbols in the common sections
should be moved to .sbss depends on its size.
I found a support in read.c / bss_alloc().
The symbol in .lcomm will be collected because bss_alloc
is called by s_lcomm. But there is no path for .comm.
So the symbols in .comm will be never moved to .sbss.
Is this a bug? or a correct behavior?

I don't think it would be correct to move .comm to .sbss, since the symbol
could be merged with a larger .comm symbol of the same name in a different
module during linking.

Thanks for your opinion.
Then, is it be correct to move .lcomm to .sbss?
And it seems symbols in .comm was moved to .sbss
when I use MIPS SDE. Is it SDE's bug?
Still I'm a little bit confused...

Sorry, I have a wrong address.
This question should be discussed at binutils-ML.
I sent it there again.
