Re: Proposal: provide cas and barriers symbols even without -threaded

Hi Simon,

That sounds like a good solution and I'll attempt a patch. I think the fix is only three lines. That is, replace these three lines with EXTERN_INLINE C functions:

#define write_barrier() /* nothing */ #define store_load_barrier() /* nothing */ #define load_load_barrier() /* nothing */

I think that should do it, yes.

That would fix the -threaded/unthreaded disparity. But I still don't see how to access this stuff properly from foreign-primops in a library such that GHCI doesn't barf when trying to load the library....

If you're referring to the problem with the missing stg_MUT_VAR_CLEAN_info symbol, I'll push a fix for that soon. Or is there something else? Cheers, Simon
