Post subject:  How to align functions?

Use GCC compiler option "-falign-functions=n":
Align the start of functions to the next power-of-two greater than n.

"-fno-align-functions" and "-falign-functions=1" are equivalent and mean that functions will not be aligned.

"-O2" and "-O3" optimization will turn on this flag.
"-Os" optimization will disable it.

Andes GCC compiler provide option "-malign-functions" to align all functions to the next 4-bytes boundary.

Functions in library may not be aligned to 4-bytes boundary.
