Well, I implemented four new opcodes (changing opcodes.h, ceval.c and
dis.py) in order to be able to play freely with compile.c. I can post
the diff outputs for anyone interested (if also it's ok in the
newsgroup, they're not long anyway), although the compile.c is not
"final" --the version I have now has only com_list_if, com_assert_stmt,
com_if_stmt and com_while_stmt touched-- but the build is stable and
passes all tests (at least test.testall, plus some checks of my own).
Bytecodes of .py[co] files are somewhat shortened, but pystone timings
are only marginally better, as expected.
At least the bytecode seems a little bit more tidy :)
