The c4x target does not build any more because a lot of code uses SImode and
DImode for 32 and 64 bit values. This is incorrect for the c4x target because
here QImode is 32 bits and HImode is 64 bits (chars/ints/longs = 32 bits, long
long = 64 bits).
I did a quick search on the current (20050209) version and found about 113
problems. The problems are listed below. I am not sure the list is complete
but it is a start.
I the past some changes were made for example to libgcc2.h, gcov-io.h. Also for
SImode one can write TYPE_MODE (integer_type_node). The same can be done for
DImode.
