The parameter defs are allocated from the parameter space using a minimum alignment of 4, and varargs functions get a va_list struct in place of the ... An "args" expression is unconditionally injected into the call arguments list at the place where ... is in the list, with arguments passed through ... coming after the ... Arguments get through to functions now, but there's problems with taking the address of local variables: currently done using constant pointer defs, which can't work for the base register addressing used in Ruamoko progs. With the update to test-bi's printf (and a hack to qfcc for lea), triangle.r actually works, printing the expected results (but -1 instead of 1 for equality, though that too is actually expected). qfcc will take a bit longer because it seems there are some design issues in address expressions (ambiguity, and a few other things) that have pretty much always been there.
