Subject: [PATCH] xtensa: fix relaxation of undefined weak references in
|
|
shared objects
|
|
|
|
The change c451bb34ae8b ("xtensa: don't emit dynamic relocation for weak
|
|
undefined symbol") didn't properly handle shrinking of relocation
|
|
sections due to coalescing of references to a dynamic undefined weak
|
|
symbol in a shared object, which resulted in the following assertion
|
|
failure in ld when linking uClibc-ng libthread_db for xtensa:
|
|
|
|
BFD (GNU Binutils) 2.31 internal error, aborting at elf32-xtensa.c:3269
|
|
in elf_xtensa_finish_dynamic_sections
|
|
|
|
Shrink dynamic relocations section for dynamic undefined weak symbols
|
|
when linking a shared object.

* elf32-xtensa.c (shrink_dynamic_reloc_sections): Shrink dynamic
|
|
relocations section for dynamic undefined weak symbols when
|
|
linking a shared object.
