/* The compiler might optimize loops or other constructs to library calls even
in freestanding mode. Although it is safe in most scenarios, on program
loading and static startup, iFUNC resolution might require other dynamic
relocation that are not yet done.
Instead of adding per-file compiler flags to avoid the libcall generation,
this header defines generic symbols that will be routed instead of the
default symbols name.
Each port can then make the required redirection to the expected generic
implementation if the symbol is provided as iFUNC, with a global definition
such as:
asm ("memset = __memset_generic");
