[PATCH] elf: Remove LD_PROFILE for static binaries
|
||
|
|
|
||
|
|
The _dl_non_dynamic_init does not parse LD_PROFILE, which does not
|
||
|
|
enable profile for dlopen objects. Since dlopen is deprecated for
|
||
|
|
static objects, it is better to remove the support.
|
||
|
|
|
||
|
|
It also allows to trim down libc.a of profile support.
|
||
|
|
|
||
|
|
Checked on x86_64-linux-gnu.
