Subject: [PATCH] xtensa: move dynamic relocations sections consistency
|
|
check
|
|
|
|
The function elf_xtensa_finish_dynamic_sections checks that sizes of
|
|
sections .rela.dyn and .rela.plt match number of corresponding relocation
|
|
records, but the check is only done when .rela.plt is non-empty, so, e.g.
|
|
it is never run for the static PIE.
|
|
Rearrange the test so that .rela.dyn and .rela.plt are checked always.

|
* elf32-xtensa.c (elf_xtensa_finish_dynamic_sections): Move
|
|
relocation sections consistency check to always check both
|
|
.rela.dyn and .rela.plt when they exist. Rearrange variable
|
|
definition and assignment places.
