Re: m68k linker scripts

Patch checked in. Thanks.

-- Jeff J.

Paul Brook wrote:
When compiling C++ code it's common to get comdat sections with names like .bss.foo. In the final output file these should be places in .bss. The libgloss m68k linker scripts don't handle these sections so ld sometimes places them after _end, with catastrophic results.

The attached patch fixes the linker scripts to include these sections.

Ok?
