Replace __attribute__((visibility("protected")))
|
|
|
fa3bfd |
|
|
|
fa3bfd |
With copy relocation, address of protected data defined in the shared
|
|
|
fa3bfd |
library may be external. Compiler shouldn't asssume protected data will
|
|
|
fa3bfd |
be local. But due to

|
|
|

|
|
|
fa3bfd |
__attribute__((visibility("protected"))) doesn't work correctly, we need
|
|
|
fa3bfd |
to use asm (".protected xxx") instead.
|
|
|
fa3bfd |
|
|
|
fa3bfd |
* elf/ifuncdep2.c (global): Replace
|
|
|
fa3bfd |
__attribute__((visibility("protected"))) with
|
|
|
fa3bfd |
asm (".protected global").
|
|
|
fa3bfd |
* elf/ifuncmod1.c (global): Likewise.
|
|
|
fa3bfd |
* elf/ifuncmod5.c (global): Likewise.
