[9front] [PATCH] cc: take our pickle out of the peephole

[9front] [PATCH] cc: take our pickle out of the peephole

[Anthony Martin]

The -P flag is used to debug the peephole optimizer. The -Z flag is
used to output pickling code for various types. Don't confuse the two.

The pickling code was added in the third edition. It mistakenly reused
the -P flag which was later partially corrected to use the -Z flag in
2004. That change updated lex.c but missed the code in pickle.c.

So this applies to 9legacy, too?  Would it be a nice gesture to
cross-post to 9fans?

Sure. I'll send a note. Though, I think anyone that actually uses
Plan 9 should be subscribed to both lists.

Cheers,

Meh.

I use 9front as my main system, and I unsubscribed from 9fans months
ago.

That place is a cesspool.

cesspool? what, one email a month?

cesspooling is not about quantity but about attitude
