misaligned_

Uses variants that are reliant on the device allowing misaligned memory accesses. This can, in some cases, make the code slightly faster or smaller. This prefix cannot be used with the parameter no.

no

Always uses the default variant with standard optimizations. The prefix misaligned_ cannot be used with this parameter.

auto

Uses variants based on runtime model attributes that indicate the requested optimization goal:

If a module is compiled with -Ohs, and the DLIB library contains a fast variant of a function that is referenced in the module, that variant is used.

If all modules referencing a function are compiled with -Ohz, and the DLIB library contains a small variant of that function, that variant is used.

This is the default behavior of the linker.

tiny

Always uses a tiny variant (minimum code size) if there is one in the DLIB library.

small

Always uses a small variant (balances code size and execution speed, favoring size) if there is one in the DLIB library.

medium

Always uses a medium variant (balances code size and execution speed, favoring speed) if there is one in the DLIB library.

fast

Always uses a fast variant (maximum execution speed) if there is one in the DLIB library.
