[PATCH v3 09/10] MIPS: Add tests for orphan REL HI16 relocation addend processing

Previous message (by thread): [PATCH v3 08/10] MIPS/BFD: Fix howto orphan REL HI16 relocation addend processing
Next message (by thread): [PATCH v3 10/10] Move mips_hi16_list to mips_elf_section_data
Messages sorted by: [ date ] [ thread ] [ subject ] [ author ]
Add GAS and LD test cases for orphan REL HI16 relocation processing, 
including verification of the addends produced as well as the warning 
messages expected.

Due to the ordering used for the list of oustanding cached HI16 reloc 
entries warnings for non-ELF links are issued in the reverse order 
compared to one for ELF links.  This is not considered a defect as all 
the required warnings are produced in both cases, however separate 
warning lists are required and included here for ELF and srec output.
---
No change from v2.

New change in v2.
