Subject: 1.0.41.25: compiler: Create sb!vm::static-fdefn-offset.
X-Git-Url: http://repo.macrolet.net/gitweb/?a=commitdiff_plain;h=34ef6951cd7243a4eaccf2efb10e6b3d2908e12b;p=sbcl.git

1.0.41.25: compiler: Create sb!vm::static-fdefn-offset.

  * Create sb!vm::static-fdefn-offset to provide the byte offset
from NIL to the tagged form of the fdefinition.

  * Reimplement sb!vm:static-fun-offset (a misnomer) in terms of
sb!vm::static-fdefn-offset.
