Subject: tweak NAME-CONTEXT
X-Git-Url: http://repo.macrolet.net/gitweb/?a=commitdiff_plain;h=7da051bf31bc6097e0096fd75df194cb1f5c6762;p=sbcl.git

tweak NAME-CONTEXT

  On platforms without UNWIND-TO-FRAME-AND-CALL vops we introduce an extra
  block, which then shows up there in the function names for eg. lambdas
  defined at the toplevel in high debug code. Fix that.

  CATCH also introduces a block. Filter those out too.
