Subject: [PATCH] ec: Use static linkage on nistp521 felem_{square,mul}
|
|
wrappers
|
|
|
|
Runtime selection of implementations for felem_{square,mul} depends on
|
|
felem_{square,mul}_wrapper functions, which overwrite function points in
|
|
a similar design to that of .plt.got sections used by program loaders
|
|
during dynamic linking.
|
|
|
|
There's no reason why these functions need to have external linkage.
|
|
Mark static.
