Comment:

Operations like these:

POP GETSTATIC PUTSTATIC GETFIELD PUTFIELD xLOAD xSTORE

(and possibly some others)

can be found enclosed in CLEAR-VALUES instructions, however, by nature, they can't be causing currentThread()._values to be set: only (lisp) function calls do that.

Comment(by ehuelsmann):

Some work has been done in this department (on the unsafe-p-removal branch): specifically, all block types are now explicitly handled, while only TAGBODY was before - and incorrectly at that.

However, the main issue still stands.

Comment(by ehuelsmann):

One of the factors determining single-valued-ness of self-compiled functions is the %SINGLE-VALUED-P field in the compiland structure.

This field gets set to T during pass1 whenever any function call within that function returns T for the call to SINGLE-VALUED-P (which itself is located in pass2???).
