Hey there, sorry about not responding. My mailer hid this message from
me. I was actually about to reply asking what the deal was. ;)

This contains the Makefile, README, .pg grammar, a -harness.pir that

shabby is the answer, as it comes in at about 1/2 the time of a P::RD
version for the simple example, and gets a bigger lead the more complex
the input expression).
I can't get this to work. If I run 'make' in the target directory, I get a
PASM file (with the .pir) extension. Then if I run either of the PIR files,
I get:
$ parrot wptest-harness.pir
error:imcc:syntax error, unexpected LABEL, expecting $end
in file 'wptest.pir' line 3
That's odd. I double-checked the diffs to make sure I didn't send out an
old version. This code works fine on my box, which I just updated to
r14904. For me, line 3 of wptest.pir is "main:". Should that be a syntax
error?
That's the very first line of code output by:
../../../parrot -o wptest.pir ../../../compilers/pge/pgc.pir wptest.pg
so if there's a problem with it, I'm not sure that I could actually fix
it. Any pointers appreciated!
Here's what I get:
$ ../../../parrot wptest-harness.pir
