[cffi-devel] LispWorks 5.0/5.1 and LONG-LONG support

[Chun Tian (binghe)]

Hi, Oliveira

With new patch, I can compile CFFI on LWL64 5.0 now.

Thank, now I can run CFFI tests. I met following issues:

LWL64 5.0:

Cannot compile tests/foreign-globals.lisp, seems in somewhere the  
FLI:FORIEGN-TYPED-AREF been called for 64-bit integers which LW 5.0  
cannot support where I have no idea. For details, see test-reports-5.0  
in attach.

LWL64 5.1:

18 unexpected failures: FUNCALL.DOUBLE, FUNCALL.DOUBLE26,
    FUNCALL.FLOAT26, DEFCFUN.DOUBLE, DEFCFUN.BFF.1, DEFCFUN.BFF.2,
    DEFCFUN.DOUBLE26, DEFCFUN.FLOAT26, CALLBACKS.LONG,
    CALLBACKS.LONG-LONG, CALLBACKS.FLOAT, CALLBACKS.FUNCALL.2,
    CALLBACKS.DOUBLE26.FUNCALL, CALLBACKS.FLOAT26,
    CALLBACKS.FLOAT26.FUNCALL, FOREIGN-GLOBALS.READ-ONLY.1,
    STRING.ENCODING.UTF-16.BASIC, STRING.ENCODINGS.ALL.BASIC.

For details, see test-reports-5.1 in attach.
I'll try to look into them to see why they're failed on LispWorks, I  
don't know whether they're LW 5.1-only bugs until I can run tests on 5.0

Both 5.0 and 5.1 give me this result, I think it's OK:

CL-USER 6 > (cffi:with-foreign-string (s "abc") (cffi:foreign-string- 
to-lisp s))
"abc"
3
