I have compiled GNU Smalltalk on the Itanium and found it to be
horribly slow --- Less than half the speed of an Intel chip with the
same clock! The reason is, the basic blocks in the interpreter are
too small for GCC to do nice instruction scheduling. Does anyone know
of pointers to papers on optimizing interpreters for VLIW
architectures?
