It implements procedure reordering as linker plugin.
I have some questions :
1 ) Can you point me to some documentation for "how to write plugin
for linkers " I am I have not seen doc for structs with 'ld_' prefix
(i.e defined in plugin-api.h )
2 ) There is one more algorithm for Basic Block ordering with
execution frequency count in PH paper . Is there any implementation
available for it ?
Quite frankly - I don't know (I've only learned about Google
implementation recently).
I've added Sriram to maybe comment.
