I use -ffunction-sections 
maybe this cause too many sections？

this opt option was used to reorder function in link stage

It seems relative to my custom ld script:

-Wl,-znorelro -Wl,-T,${CMAKE_SOURCE_DIR}/rpm/ld.lds

When I remove : -Wl,-T,${CMAKE_SOURCE_DIR}/rpm/ld.lds
It success.

The link script’s content is:

SECTIONS
{
 memory_context_static_id :
 {
   KEEP(*(SORT(memory_context_static_id*)));
 }
 co_buffer :
 {
   KEEP(*(*CO_BUFFER_BEGIN*))
   KEEP(*(*COBUFFER*))
   KEEP(*(*CO_BUFFER_END*))
 }
 co_hook :
 {
   KEEP(*(*CO_HOOK_BEGIN*))
   KEEP(*(*COHOOK*))
   KEEP(*(*CO_HOOK_END*))
 }
}


is it caused by incorrect usage of ld script for gold ?

If so, how can I use this script correctly for gold.
