In PR 15370, it is noted that gold does not distinguish between "*(.foo .bar)" and "*(.foo) *(.bar)" in linker scripts. In both cases, gold groups all .foo sections together, followed by all .bar sections, whereas in the first case, it should collect all .foo and .bar sections in the order seen. If you add sort specs, the Gnu linker has some bizarre corner cases that I do not try to replicate. In particular, "*(SORT_BY_NAME(.foo) SORT_BY_NAME(.bar))" does the same thing as "*(.foo) *(.bar)". But if you apply a sort spec to just one of several patterns, say, "*(SORT_BY_NAME(.foo) .bar)", the Gnu linker will collect any .bar section it sees before the first .foo, then all .foo sections, then all remaining .bar sections. With this patch, if any of the input patterns have a sort spec, gold will group them all as it did before; e.g., all .foo sections followed by all .bar sections. 2015-06-03 Cary Coutant <ccoutant@gmail.com> gold/ PR gold/15370 * script-sections.cc (Output_section_element_input::set_section_addresses): When there are several patterns with no sort spec, put all sections in the same bin. * testsuite/Makefile.am (script_test_12): New testcase.
