Rafael Espindola	1960bcd710	Don't sort sections in -r links. Unlike gold, bfd, gas or MC we were putting exidx sections first since they are ro. The spec doesn't explicitly say that they must come after, but it is definitely more convenient for the consumer, matches other producers and matches other areas in ELF (like SHT_GROUP) where sections are ordered in a natural way. llvm-svn: 286659	2016-11-11 22:43:27 +00:00

Don't sort sections in -r links.

Unlike gold, bfd, gas or MC we were putting exidx sections first since
they are ro.

The spec doesn't explicitly say that they must come after, but it is
definitely more convenient for the consumer, matches other producers
and matches other areas in ELF (like SHT_GROUP) where sections are
ordered in a natural way.

[ELF] Add sh_link field to .ARM.exidx sections for relocatable links

When doing a relocatable link the .ARM.exidx sections with the
SHF_LINK_ORDER flag set need to set the sh_link field to the executable
section they describe. We find the appropriate OutputSection by
following the sh_link field of the .ARM.exidx InputSections.
    
The getOutputSectionName() function rules make sure that when there are
multiple .ARM.exidx InputSections in an OutputSection they all have the
same sh_link field.
