So for divc3 in libgcc2.c...
#elif defined(L_muldc3) || defined(L_divdc3)
# define MTYPE DFtype
# define CTYPE DCtype
# define MODE dc
I assume that BUILT_IN_COMPLEX_DIV_MIN and MIN_MODE_COMPLEX_FLOAT will be
available to me in darwin.c but where is dc defined? I am looking to be
able to execute...
tree fn = built_in_decls[BUILT_IN_COMPLEX_DIV_MIN + sc -
MIN_MODE_COMPLEX_FLOAT];
or is MODE not the same as mode?
