Subject: For PowerPC, never put a reg_float value in a reg_any.
X-Git-Url: https://git.ndcode.org/public/gitweb.cgi?a=commitdiff_plain;h=e6df553ebf6280e0821c32077bf02c6651c4ab46;p=ack.git

For PowerPC, never put a reg_float value in a reg_any.

With this type check, I can change the size checks into assertions.
