After many merry rounds of compilation and discovery, it seems that the
ndk-build's compiler -falign-functions[=n] and friends align functions relative
to this option, but off by one (+1, or is that just |1?).;-)
In pico.h, sadly, I besmirched the code thusly,
#ifdef ANDROID_ARM
// android arm seems to have weird off-by-one alignment
#define FUNCT2LISP_ALIGN(f) ((f)-1) // hopefully optimise to
#define LISP2FUNCT_ALIGN(f) ((f)+1) // a single inc ...
#else
#define FUNCT2LISP_ALIGN(f) (f)
#define LISP2FUNCT_ALIGN(f) (f)
#endif
#define evSubr(f,x) (*(fun)( LISP2FUNCT_ALIGN( num(f) ) & ~2 ) )(x)
so in boxSubr in main.c,
if (num(FUNCT2LISP_ALIGN(f)) & 3)
giveup("Unaligned Function");
return (any)(num(FUNCT2LISP_ALIGN(f)) | 2);
(Er, I bet I missed some places, need to check.)
And then to talk with java I used the miniPicoLisp string-based library mods
mentioned earlier, with a little jni C glue to hold it together.
Cheers,
Doug
