Subject: [PATCH] or1k: fix pc-relative relocation against dynamic on PC
|
||
|
|
relative 26 bit relocation
|
||
|
|
|
||
|
|
When building openal we were seeing the assert failure:

|
This happens because in R_OR1K_INSN_REL_26 case we can't reference local
|
||
|
|
symbol as previously done but we need to make sure that calls to actual
|
||
|
|
symbol always call the version of current object.
|
||
|
|
|
||
|
|
bfd/Changelog:
|
||
|
|
|
||
|
|
* elf32-or1k.c (or1k_elf_relocate_section): use a separate entry
|
||
|
|
in switch case R_OR1K_INSN_REL_26 where we need to check for
|
||
|
|
!SYMBOL_CALLS_LOCAL() instead of !SYMBOL_REFERENCES_LOCAL().
