[sdcc-devel] Support functions (multiplication) in sdcc

In generated code I see calls to support functions such as
__muluchar_rrx_s. There seem to be differences in these support
functions among the ports. Where can I find out what these functions are
supposed to do (the above one seems to multiply to unsigned chars to get
an unsigned int, but what does the "_rrx_s" mean?)? How can I introduce
new such functions, how remove them?
